[f28] radiotray does not work

[Marco Guazzone]

Hello,

Just done a fresh installation of Fedora 28.

Unfortunately, radiotray does not work; it crashes on start with the
following error:

  pygobject_register_sinkfunc is deprecated (GstObject)

This is a well-known bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1388161

Until Fedora 27 the following workaround used to work:

  $ dnf install python-gstreamer1 dbus-python radiotray

But it does not in Fedora 28.

Any suggestion?

Thank you so much.

Marco

[F28] Unable to use ACM LaTeX class with pdflatex

[Marco Guazzone]

Hello,

I'm using the latest ACM LaTeX class (version 1.53):
  https://www.acm.org/binaries/content/assets/publications/
consolidated-tex-template/acmart-master.zip

I've installed the required packages.

With Fedora 27, no problem.
Instead, with Fedora 28, when I run the following command:

  $ pdflatex sample-sigconf

I get the following error:

  kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 0+540/600 --dpi 540
txsys
  mktexpk: don't know how to create bitmap font for txsys.
  mktexpk: perhaps txsys is missing from the map file.
  kpathsea: Appending font creation commands to missfont.log.
   )
  !pdfTeX error: pdflatex (file txsys): Font txsys at 540 not found
   ==> Fatal error occurred, no output PDF file produced!

As an alternative, I can use latex+dvipdfmx commands to first generate a
DVI and then convert it to a PDF. However, the resulting PDF looks
different from the one contained in the acmart-master.zip file.

I've just submitted a bug on Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1595278

Any idea?

Thanks for your help.

Hi,

Similar issues here, started since kernel-4.17.4.

Don't know how to reproduce this problem.
It happened under different situations (e.g., when running a backup program
or when watching a live video)

Marco

Just tried to rerun my backup program (duplicity writing to Google Drive):
With kernel 4.17.5 -> system hangs
With kernel 4.17.3 -> no problem.

Hi,

Before kernerl 4.17.7, I had issues during my duplicity-based backups.

With kernel 4.17.7, no issue to date.
I've been testing it since its release in Fedora 28.

[f28] Unable to print from Fedora 28

[Marco Guazzone]

Hello,

Today I am having trouble in printing from Fedora. I have tried two
different network printers without success.

Specifically, if I print a test page (in XFCE, open the "Print Settings"
application and click on the "Print Test Page"), cups says that the page
has been printed successfully:

Sep 17 10:27:33 wildcat cupsd[799]: UPO-KyoceraKM3035-LotB sguazt 172
[17/Sep/2018:10:27:33 +0200] 1 1 - localhost Test Page - -
Sep 17 10:27:34 wildcat cupsd[799]: REQUEST localhost - - "POST / HTTP/1.1"
200 364 Create-Printer-Subscriptions successful-ok

But the printer does not receive any data.

My system is an up-to-date Fedora 28 x86_64 (kernel:
4.18.7-200.fc28.x86_64).
Last time I have successfully printed to these printers from Fedora was Sep
12, 2018.
The printers work without problems under Windows 7.

Any idea?

Thank you in advance for your help.

Cheers,

Marco

For you interest, a downgrade of cups from ver. 2.2.6-22 to ver. 2.2.6-14
does not solve the problem.

Solved!
After downgrading ghostscript from from 9.24-1 to 9.23-1, I am able to
print again.
See: https://bugzilla.redhat.com/show_bug.cgi?id=1629086

F13: strange default for PDF viewer

[Marco Guazzone]

Hi,

I've noticed that the default PDF viewer in
"/usr/share/applications/mimeinfo.cache" is GIMP:

application/pdf=gimp.desktop;evince.desktop;

In fact, when I try to open a PDF from firefox, it is open with GIMP.

If I'm not wrong, in F12 the default was EVINCE

Any idea of this change?

Thanks,

Thank you very much for pointing it out.

Looking at this file I can see:
 application/pdf=AdobeReader.desktop

So why does Firefox try to open a PDF with GIMP?

And why I have the entry
  application/pdf=gimp.desktop;evince.desktop;
in file
  /usr/share/applications/mimeinfo.cache
?

Thanks!

I partially agree with you. I selected "Always Ask" since in some
cases I just want to open a PDF file to have a quick look inside. ;)

Anyway, to overcome this issue I created an entry for PDF mime in my
own personal area:

$HOME/.local/share/applications/mimeinfo.cache

where I put this:

application/pdf=evince.desktop

Now all works right.

Thank you very much!!

F13: Delay in screen refresh

[Marco Guazzone]

Hi,

I've noticed that there is a some kind of "delay" in the screen refresh.
For instance, under VIM when I move the cursor (that is a black
rectangle) under a character,  it takes between 1 and 4 secs before
the character appears inside the cursor.
I've experienced the same issue under OpenOffice and FireFox.
This is really annoying. :(

Under F12 no problem

Does any other experienced this behaviour?

My system is:
* OS: F13 x86_64 - up-to-dated
* WM: OpenBox
* CPU: Intel Core 2 Duo
* GPU: Intel GM965/GL960
* RAM: 2GB

Thank you so much!

Hi!

It seems that this problem is only affecting me.

In the meanwhile I've noticed that this delay seems to be really X
dependent, since almost every applications exhibits it.
For instance, I've tried with:
* bash inside xterm (e.g., execute "ls" and then move up with Shift+PgUp)
* gvim
...

Please, can anyone help me?

Thank you very much!!

No process seems to have a great impact on CPU usage.
These below are the more time consuming processes:

 1563 root  20   0  172m  42m  11m S  3.6  2.1   4:39.59 Xorg
 2751 marco20   0  942m 173m  30m S  3.6  8.7   4:32.69 firefox
 2790 marco20   0  419m  19m  10m S  2.0  1.0   2:11.23 npviewer.bin

After refresh, Xorg goes from 1.0 to 2.5 % of CPU. This percentage
increase to ~16% when I switch between wm virtual desktops.

Done, but no meaningful information (or maybe I don't know what to look for).

Hi thank you for replying.

Here below is the information you have asked

But before you dig into it I want to say that it seem a problem of the
OpenBox window manager.
I say so since I've tried to use GNOME and apparently the problem
seems to be disappeared (for instance under ViM there is no delay in
showing characters under the cursor).
While the problem reappears if I turn to OpenBox (without GNOME).
Very strange, under F12 I had no problem even with the same version of OpenBox.
I think I should post a bug report, do you?

Sure here below the output. This is taken while moving the cursor
inside ViM character-by-character (I confirm the delay of some second
in showing the character under the cursor)

It's a light-weight window manager and you can try It with LXDE Fedora
spin: http://spins.fedoraproject.org/lxde/

I speak too quickly! :(

The problem appears also under GNOME.
I've tried with xterm, ViM, and OpenOffice.
For instance, with oowriter the "latency" problem happens during
tooltip drawing (e.g., go to File -> Recent Documents and then move
the mouse up and down along the list of open documents slow enough
(but not too slow) in order to let the tooltipo appears; in this case,
I can note a delay which make appear an empty cyan rectangle and after
a few the tooltip text)

:(((

Workspace cycle under GNOME

[Marco Guazzone]

Hi all,

Is there a way to tell GNOME to do workspace cycle?

By "workspace cycle" I mean that the WM considers:
* the Workspace 1 as the next workspace of the Last Workspace (e.g. to
pass from Workspace 1 to the last Workspace by pressing
Ctrl-Alt-LeftArrow), and
* the Last Workspace as the previous workspace of the Workspace 1
(e.g., to pass from the Last Workspace to Workspace 1 by pressing
Ctrl-Alt-RightArrow).

I did a search and from what I found it seems GNOME does not allow it,
but I hope this is not true :(

Thank you very much,

Best,

Thank you.

Just tried.
It seems that you get this behavior only if you also select the option
"Workspaces on a Cube", something that I don't like too much :-/

Just for curiosity. Someone knows why this basic behavior (also
present in several old WM) is not included in "plain" GNOME (i.e.,no
compiz).

Thank you so much!

Thank you!

It works!
I've created two scripts: one for moving left and another for moving
right and I've bound them on Left and
Right respectively (disabling the default bindings for
these keys).

Thank very much!!

Finally, it seems that some of the recent updates solved this annoying problem.

F13: Empathy stop working after 'yum update'

[Marco Guazzone]

Hello,

After having successfully completed 'yum update', empathy stop working well.

Specifically, once executed, it does not show in the Gnome
notification area even it appears in the process list.

I attach a log file created with empathy-debugger.

Note: I use empathy for chatting with gtalk.

Hope this help.

Thank you very much.

Best,

By simply executing 'yum downgrade empathy' I get a dependency resolution error:

Hi!

I have a similar problem: every time evince starts, it does with a
large window (which cover my wm panel bar) which I have to resize.

I'm running F13 with openbox (and with gnome-settings-daemon running
in background).

Under F12 had no problem.

Any help would be very appreciated.

Best,

Yes, I have.

In order to quiet rkhunter, you can insert the line:

ALLOWHIDDENDIR=/etc/.java

in your /etc/rkhunter.conf

Never used but looking at the sample page

Here is a possible list of programs:

http://www.digitizeit.de/
http://www.ccp14.ac.uk/solution/hardcopy2data.htm

maybe not directly available through yum.

good luck! ;)

So I'm not alone.

I have a similar problem:

https://bugzilla.redhat.com/show_bug.cgi?id=1298826

but still waiting for a solution.

As you I have no workaround except for crossing my fingers before I open
LibreOffice. But, it works only occasionally.

I have a Dell Latitude E5430.

F25: XFCE won't start

[Marco Guazzone]

Hello,

I've installed F25 Workstation x64 from Live iso (GNOME window manager).
Now I want to run XFCE window manager.

I installed it with:

   dnf groupinstall Xfce

Then rebooted and tried to log in (by selecting XFCE from GDM).
But after clicking on the log in button, XFCE seems to have problems and
the screen immediately comes back to the GDM login.

Any idea?

Thanks.

It turns out that GDM doesn't like XFCE

Indeed, after enabling lightdm in place of GDM:

   sudo systemctl enable lightdm --force

XFCE can start.

I found these discussions very helpful:
-
https://stackoverflow.com/questions/53084955/why-does-slack-return-a-segmentation-fault-after-fedora-29-upgrade
- https://github.com/electron/electron/issues/13972

Try the following steps, where you are going to replace the original
"libnode.so" library shipped with Slack with another working version:
1. Download Electron v2.0.13
  $ wget
https://github.com/electron/electron/releases/download/v2.0.13/electron-v2.0.13-linux-x64.zip
2. Extract in a temp dir:
  $ mkdir electron
  $ cd electron
  $ unzip ../electron-v2.0.13-linux-x64.zip
3. Replace the Slack's libnode.so with the Electron's one:
  $ sudo cp -v /usr/lib/slack/libnode.so /usr/lib/slack/libnode.so.orig
  $ sudo cp -v libnode.so /usr/lib/slack/libnode.so
4. Run Slack.

I hope this helps.

Marco

I also experienced some problems with XFCE 4.13 in Fedora 29:
- weird colors in the workspace switcher (it is difficult to understand
what is the current workspace)
- icons in systray do not fit well
- windows sometimes forget their maximization status: if a window is
maximized and then "unmaximized", sometimes that window remains maximized
(currently, this happened only with xfce-terminal)
- some apps has strange behaviour; for instance, the welcome screen of
AndroidStudio does not appear at the center of the screen and the menu of
the AndroidStudio window looks shifted towards the left
- the XFCE's Applications Menu takes long to appear the first time

I'm also experiencing this flickering issue under XFCE.
If I open LibreOffice and leave the mouse pointer over a recent document
preview image, this image starts blinking.
A similar issue happens if I leave the mouse pointer over a menu icon
(e.g., open a document and move the mouse pointer over the "Save" button;
the image will start flickering).

This issue is not present under GNOME (I tried both in the Wayland and the
X.org version of GNOME).

[F29] Command dvipdfmx (texlive) does not work

[Marco Guazzone]

Hi,

On my Fedora 29, the command dvipdfmx does not work:

$ rpm -q texlive-dvipdfmx
texlive-dvipdfmx-20180414-28.fc29.x86_64
$ dvipdfmx
bash: dvipdfmx: command not found

Indeed, the executable file '/usr/bin/dvipdfmx' is a broken link that
points to a nonexistent file:

$ ls -al /usr/bin/dvipdfmx
lrwxrwxrwx. 1 root root 9 Nov 26 19:22 /usr/bin/dvipdfmx -> xdvipdfmx
$ ls -al /usr/bin/xdvipdfmx
ls: cannot access '/usr/bin/xdvipdfmx': No such file or directory

I tried to reinstall the texlive-dvipdfmx package with no success.
I already filed a bug: https://bugzilla.redhat.com/show_bug.cgi?id=1657755

I would like to know if some of you has this problem too, and if (s)he
already found a workaround.

Thank you in advance for your help.

Best,

[F29] Ext4 file system inconsistencies

[Marco Guazzone]

Hello,
I'm running an up-to-date Fedora 29 x86_64 (kernel 4.19.13-300.fc29.x86_64).

My ext4 file system got inconsistent twice in a week: the first time, the
'/home' partition; the last time, both '/root' and '/home' partitions.
I had to use a live distro to fix it with fsck.

I ran several disk test utilities to check for HW errors, including:
* HDDScan 4.0 (http://hddscan.com/): VERIFY, READ and BUTTERFLY tests
* Diagnostics tests from Dell's BIOS
* SMART self-test
All these tests succeded: no problem detected.

If I exclude HW errors, the only other option is a SW error (in the
kernel?).

Any idea?

Thank you for your help.

Hello,
Just for the record, ext4 has just become inconsistent again.
Luckily, I had with me a USB with a live image so I could run fsck.

Hi,

[I resend the message without the memtest screenshot because the previous
one is awaiting for moderation]

Yes, I ran memtest days ago and I've just run it again today. The memtest
version I'm using is the PassMark's memtest86 v.8.1.

All tests passed.

Thank you.

Cinnamon 4.6 makes my display flickering

[Marco Guazzone]

Hi,

I have just upgraded Cinnamon to the new 4.6 version with dnf and then
rebooted the system.

When I log in, Cinnamon makes my screen flickering, with half screen blue
and the other half screen showing (a half of) my background image.

Just for testing, I created a new user to start Cinnamon with a fresh new
configuration. Same problems experienced

If I use Gnome shell (Classic), then I log out, and then I use Cinnamon the
problem disappears, apparently.

Any idea?

I am experiencing similar issues in Fedora 33 (I performed a fresh install
as well).

Occasionally, my system has no audio (with pulseaudio that is unable to
connect), and to get it back I have to run these commands:
  $ pulseaudio --kill
  $ pulseaudio --start

I suspect that the problem could be ascribed to the desktop environment
that I am using (i.e., Cinnamon), as every time I tried to use Gnome I
didn't experience that problem.
There were no such problems in Fedora 32.
My audio interface is integrated in my laptop's motherboard.

Best regards,
Marco

[F21] NetworkManager won't connect

[Marco Guazzone]

Hello,

I have connectivity problem since the last two updates of NM.
Specifically, when I boot the system and I log in in the graphical
environment (XFCE in my case), the NM applet continuesly animates,
trying to connect to my network.
I can wait any time (actually I've tried for a max waiting time of 10
minutes), but NM seems to have trouble to connect.
In order to connect I have to:
1. Right-click on the NM applet and deselect "Enable Networking". The
applet stops animating
2. Again, right-click on the NM applet and re-select "Enable
Networking". Now, NM successfully connects to the network.

Am I alone to experience such problem?

The NM version is 0.9.10.1-1.2.20150109git for Fedora 21 x86_64

Cheers,

-- Marco

I've just updated NM to the version that is currently in updates-testing
  http://koji.fedoraproject.org/koji/buildinfo?buildID=604111
and the problem seems to be fixed.

In my case, the patched NM solved the problem.

If you want, you can try it as follows:
1. Enable the yum repo /etc/yum.d/fedora-updates-testing.repo
   $ sudo vi /etc/yum.d/fedora-updates-testing.repo
   (change "enabled=0" in "enabled=1")
2. sudo yum update NetworkManager
3. Disable the "feodra-updates-testing" repo
   $ sudo vi /etc/yum.d/fedora-updates-testing.repo
   (change "enabled=1" in "enabled=0")
4. Reboot and cross your fingers

OK. Sorry for the typo. The right repo file is the one pointed out by poma

@antonio: the procedura I've described (except for the typo) is
exactly the same one I've done. Don't know why you don't see the new
NetworkManager.

Anyway, I think it will land in the fedora-updates repo soon.

F22: XFCE issues

[Marco Guazzone]

Hi,

the command

$ dnf group install XFCE

installs kernel debug stuff (kernel-debug-core, kernel-debug-modules,...).
I have to remove them after installation.

Also, XFCE runs gnome-shell!
Unless I miss something from last XFCE updates, I think this is wrong

Cheers,

Marco

Hi all,

For the kernel debug stuff, I think I've found the problem.

If you look at the output of:

$ dnf group info Xfce

you'll see the package NetworkManager-l2tp

Now, if you install this package, then you'll get the kernel debug
stuff. That is:

$ dnf install NetworkManager-l2tp

Installing:
 NetworkManager-l2tp   x86_64
  0.9.8.7-3.fc22
fedora 95 k
 kernel-debug-core x86_64
  4.0.4-301.fc22
fedora 20 M
 kernel-debug-modules  x86_64

fedora1.1 M
 xl2tpdx86_64

For the gnome-shell issue, I confirm I still use GDM (like I did in F21).
From GDM I choose the XFCE session.

I think not. I installed F22 workstation, then I run "yum update"
(which translated into "dnf update") and finally I installed XFCE with
the above command

Yes, it does. It also removed libreswan xl2tpd

But this has changed since F21. I'm pretty sure that in F21 the use of
GDM did not lead to the execution of gnome-shell under XFCE (not even
under MATE and CINNAMON, all of those started from GDM)
To me, it looks like a bug (not necessarily of XFCE, say of F22)-

Agree!

Indeed, lightdm has solved the problem.

OK. But unlike Fedora 22, in Fedora 21 there wasn't a gnome-shell
process running together with XFCE.
Probably something has changed in the GDM version shipped with F22
Indeed, I didn't noted the parameter "--mode=gdm" passed to
gnome-shell, which might run a "lightweight" version of gnome-shell
needed by GDM

Anyway, to see gnome-shell running inside XFCE was rather confusing
and disappointing (since I don't like gnome-shell) ;-)

F22: Touchpad and Middle click

[Marco Guazzone]

Hi,

I've installed F22 on a Dell E5430 laptop.
I've noted the following behavior upon text selection:
- with an external mouse, the middle works as expected, that it pastes
the currently selected text
- with the touchpad (which has two buttons), the simultaneous pressing
of left and right buttons does not paste the selected text as I expect
(until F21 it worked)

I've tried both on GNOME, XFCE and Cinnamon.

I don't know if this may be a consequence of using libinput as described here:
https://fedoraproject.org/wiki/Changes/LibinputForXorg

I've found similar questions in the AskFedora and FedoraForum sites,
but for both there is no answer yet.

Anyway, does anybody have a tip to solve this issue?

Thank you very much for the help

Best,

Marco

Hi Bob,

Thank you for the suggestion.

Unfortunately, it doesn't work.
1. I've created that file and put the content you suggested
2. I've reboot the system
3. After logging in, I've tried to select & paste with touchpad from
the terminal:
- with XFCE terminal, the effect is like a right-click followed by a
left-click (i.e., it opens a new terminal window)
- with XTerm, the effect is a "do nothing"

I'm considering to report a bug, unless someone tells me this is a new
feature of F22

Cheers,

Marco

Thank you, Kevin.

Unfortunately, it doesn't work.

Also, note that this option and the man page to which you refer is for
the "mouse" driver.
As far as I know, input devices in Fedora are managed by the "evdev"
driver (see man evdev)

Just for the record, I've also tried to replace (in the file above)
the "evdev" driver with the "synaptics" driver.

As before, it doesn't work

Best,

Not exactly the same. This may depend by the fact that F22 uses

Hi,

There is a bug report here:

https://bugzilla.redhat.com/show_bug.cgi?id=1205771

It's already closed. I've just added a comment about my problem hoping
that it will be reopened.
Thank you both for the help.

Best,

F20: Touchpad vertical scroll for Dell Latitude E5430

[Marco Guazzone]

Hello,

I've installed F20 x86_64 on my Dell Latitude E5430.

Unfortunately, it seems that the vertical scroll with the touchpad
(i.e., when you vertically scroll the page by moving up & down your
finger) doesn't work.
This includes both the single-finger and the double-finger vertical scroll

Any idea on how to get it working?

Thank you for your time!

Hi poma,

Thanks for pointing it out.

I've realized that to make the single-finger vertical scrolling
working (at least in XFCE) I have to enable it on the system settings,
where, after selecting the device "AlpsPS/2 ALPS GlidePoint" and the
"Touchpad" section, you can choose between either 'edge scrolling'
(i.e., the single-finger scrolling) or the 'two-finger scrolling'.
If I select 'edge-scrolling', the single-finger scrolling works like a charm.

Cheers

Yeah, Xfce is cool & light.
And it allows you to customize your environment as you like...
Something that GNOME 3 (and also 2) don't allow (neither with the
gnome-tweak-ui tool) and this is the main reason why I don't like
GNOME.
There are very cool gnome-extensions, but it seems they become
unusable after a new GNOME 3 version is out (I experienced this in the
past)

Hi,

I've just tried mcpdf. Wrt pdftk is very limited as it does not
implement a lot of functionalities (e.g. encryption,...)

It seems it only supports the following operations: fill_form, output, flatten
Anyway, many of the missing functionalities are already available in iText

Re: Canon LIDE 120 scanner - should I expect this never to work?

[Marco Guazzone]

Hi,

I've experienced similar issues with an old CanonScan.
It worked until Fedora 19, but not in Fedora 20.
I've tried with:
simple-scan
xsane
gimp + sane plugin
command line: scanimage -d plustek ...
The last one returned an I/O error. Just to make sure it's not a
scanner problem, I've asked a collegue of mine (which runs a fedora
19) to test it and it worked.

I hope that Fedora 21 (that I'm going to install in the next few days)
can bring it back to life.

Best,

Re: Canon LIDE 120 scanner - should I expect this never to work?

[Marco Guazzone]

Hello,

Bad news.
I've just installed F21 but unfortunately I'm not able to scan with my
Canon (CanonScan N1240U)

It is recognized by the system:
$dmesg
...
[17610.424208] usb 3-3: new full-speed USB device number 4 using xhci_hcd
[17610.602439] usb 3-3: New USB device found, idVendor=04a9, idProduct=220e
[17610.602450] usb 3-3: New USB device strings: Mfr=64, Product=77,
SerialNumber=0
[17610.602456] usb 3-3: Product: CanoScan
[17610.602460] usb 3-3: Manufacturer: Canon

SANE recognizes it:

$ sudo sane-find-scanner
found USB scanner (vendor=0x04a9 [Canon], product=0x220e [CanoScan])
at libusb:003:004

but cannot scan:

$ scanimage -T
scanimage: no SANE devices found

$ scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).


On the SANE web page, it seems that this scanner is supported via the
plustek backend since version 0.52 (the version shipped with F21 is
1.0.24)

So, are you saying that scanimage -T/-L must be run via sudo?
I thought it could be run as a normal user.
Anyway, I've tried with "simple scan" (which I'm pretty sure it does
not require special permission) and don't work as well

Hi,

@Frank_McCormick: unfortunately your solution doesn't work for me.

@poma: before touching udev I opted for bugzilla ;)

I've found an already opened bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1100151

I confirm I successfully use rpmfusion in Fedora 21.
The repo is available at least since a week.

However, be aware that some package are still labeled as fc19 and you
get an error if you try to install it.
For instance 'gmameui':

$ sudo yum install gmameui

The GPG keys listed for the "RPM Fusion for Fedora 21 - Nonfree"
repository are already installed but they are not correct for this
package.
Check that the correct key URLs are configured for this repository.


 Failing package is: gmameui-0.2.13-0.4.20120704cvs.fc19.x86_64

Re: Radiotray no sound

[Marco Guazzone]

Hello,

The radiotray project seems to be dead.
I suggest using radiotray-ng which is available in the Fedora repo. I use
it since Fedora 30 without problems.
Alternatively, you may try radiotray-lite (
https://github.com/thekvs/radiotray-lite), which I used on my machine until
Fedora 30.
Both projects are written in C++ and are very lightweight; however,
radiotray-ng seems to be more actively maintained.

Regards,
Marco

Preserving @home brtfs subvolume on a fresh Fedora installation

[Marco Guazzone]

Hello,

I have just done a fresh installation of Fedora 34 on a new computer and
used the automatic disk partitioning proposed by the installer.
Now my disk has the following layout:
- /boot (ext4)
- /boot/efi (EFI system partition)
- / (btrfs), with two subvolumes: @root and @home.

In case of a new fresh installation of Fedora, I would like to preserve the
@home subvolume only and instead overwrite the rest. However, I am not sure
what I should do (note, I don't want to use dnf upgrade).

Just as an experiment, I tried to simulate a fresh (re)installation of
Fedora 34 and I selected "Custom" as the disk partitioning method. The
installer showed the above disk layout. So, my idea was to use the same
approach I used in the past (with ext4 partitions). Specifically:
* For the "/boot" and "/boot/efi" partitions, I specified "/boot" and
"/boot/efi" as mount points, respectively, and flagged the "Reformat"
checkbox.
* For the "/home" subvolume, I specified "/home" as the mount point,
without flagging the "Reformat" checkbox.
* For "/", I cannot tell the installer to reformat it. I am not sure what
to do. I would create a new btrfs filesystem with "/" as the mount point,
but I am not sure it is correct.

Do you have any suggestions?

Thank you.
Marco

Thanks a lot, Chris!

That page is exactly what I was looking for.
I followed each step and all went OK.
In case that document is targeted also to inexperienced users, I would
suggest the following changes:
* Step 5: specify to click on "Done" after selecting "Custom"
* Step 10: specify how to remove the "root" subvolume, also mentioning what
to do when the dialog box "Are you sure you want to delete all of the data
on root?" appears.

Thank you.
Best regards,
Marco
