If you think the layout is problematic, I'd suggest discussing it on
the Evo mailing list and eventually filing an RFE.

The icons are determined by the current style dictated by Gnome, not by
Evolution itself. The same applies to fonts.

RPM Fusion GPG not Found

2020-06-09 Thread Stephen Morris

Hi,
    As part of upgrading F31 to F32 using 'dnf system-upgrade download 
--releasever=32', dnf downloaded all packages and downloaded and 
installed the gpg for rpmfusion-free, but it was not able to download 
and install the gpg for rpmfusion-nonfree, and hence would not recognise 
the system as being rebootable to do the upgrade until I manually 
downloaded and imported the rpmfusion-nonfree gpg data. Has anyone else 
encountered this situation?


regards,
Steve

Thanks. I tested that and although the hdparm succeeded, the drives
don't power down. I think this particular dock has its own ideas about
idling the drives and won't do it as long as the interface is online.

DNF Upgrade of F31 to F32 did not Update Grub

2020-06-09 Thread Stephen Morris

Hi,
    After eventually getting 'dnf system-upgrade download 
--releasever=32' to download and reboot the system, when the upgrade had 
finished the system booted into sddm. When I selected KDE to start into 
all it did was display a black screen. If I selected Gnome, that did 
exactly the same thing. To try to work around this I booted into 
recovery mode to see if I could identify why this was happening. Looking 
at /boot I found that an F32 kernel had been installed, and when I 
looked at /boot/efi/EFI/fedora/grub.cfg I found that there was no entry 
for the F32 kernel. To circumvent this I issued the command 
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg, and rebooted via the 
F32 kernel entry, which then enabled KDE and Gnome to both start 
successfully. Has anyone else seen the issue of the F32 upgrade not 
updating grub?

Steve

Surely a VM would see only virtual cores and not be aware of the host.
However this is running on Windows, so who knows. You might want to
mention which VM it is (VirtualBox, VMware, Microsoft's, ...)

Re: How do I change the grub kernel boot parameters in F32 ?

update-grub{,2} is a debian/ubuntu-ism, I believe.  I typically use
grub2-mkconfig after modifying /etc/default/grub.

One thing I've noticed, if you've used grubby to add/modify kernel
arguments, on default Fedora configs, it modifies all the files in
/boot/loader/entries/*.conf to have hard-coded kernelopts.  By
default, it uses $kernelopts which is defined in the default grub.cfg
but once grubby is run they're hard-coded in each entry file.  So
running grub2-mkconfig doesn't do anything anymore.  You might not
even realize you've used grubby, but packages like the rpmfusion
akmod-nvidia package runs it to add the blacklist kernel options.

Maybe this is a bug that has been fixed since I encountered it?

Thanks Tom, I'll try that option and see what happens. There is also one 
other thing I don't understand. If I run dolphin, under the Remote 
Section in the left hand panel it shows the entry /mnt/HD/HD_a2:/mnt/nfs 
on 192.168.1.12 which matches the fstab entry, and when I click on that 
entry, dolphin successfully displays the contents of my nas drive. Given 
the manual mount process doesn't work what is dolphin using to actually 
access the drive?

Thanks Patrick, I'm using VirtualBox now, I was using Vmware Player, but 
I switched to VirtualBox because VirtualBox supports uefi where as 
Vmware doesn't. I was just wondering whether because the VM is sharing

the issue be that windows itself was using Core 7 and hence rcu couldn't

I just installed Fedora 32 on a machine 2 days ago, and had to install
the nvidia drivers because nouveau kept crashing (alas!).  I installed
the rpmfusion akmod-nvidia package, and the corresponding kernel entry
has this:

options $kernelopts

So it looks like the grubby issue has been fixed.

Re: NFS Mount Point Failed

2020-06-09 Thread Roger Heflin
I used linux in 2.0.X kernels (vintage 1998), and we used version=2,
so I am going to guess there was never a version 1 on linux.

And wikipedia says this interesting bit I did not know:
Sun used version 1 only for in-house experimental purposes.

So I guess that says no one outside of sun used version 1.

I suspected that's the case, so it'd be pointless complaining to
Evolution about the icons drawn by someone else.

I usually delete by hitting the delete key on the keyboard, anyway. 
But I mention it as an example of an unclear icon.  Here's another: 
I've got an app on the phone for controlling smart lights, it lets you
pick provided icons for your presets, but the images all have no
meaning, and you can't create your own images.  Or the controllers on
video games that I never play, there's nothing sensible about why a
game uses the square button, or the green button, etc., it's all
arbitrary.  They do nothing to contribute to ease of use.

Bye,
Tim.

I think if you view /etc/mtab you'll see the parameters being used for
everything that's currently mounted.

AFAIK that wouldn't happen. The cores you are seeing in the guest are
virtualised. They aren't the real cores of your host CPU.

You could however make suggestions about the layout, i.,e. the order of
icons on the top row. That's determined by Evo.

Years ago, I think about the time OSX first appeared, there were 
reports of an eminent industrial psychologist (whose name I've forgotten) 
who had said that all modern GUIs were downright wrong-headed. Does 
anybody remember? And was that insight ever followed up on? (I believe

I don't recall that one, but I remember this little gem from Doug Gwyn in 1991:

It's my wife's previous machine, a System76 PC from several years 
back. (She thinks five to eight years.) Being from them, it arrived with 
Ubuntu (only, afaik). But I had so much trouble installing Fedora 
(trouble I had not had with an early System76 netbook) that I had to call 
a friend here, who came and did the install for me. 

All I can think of, and it seems unlikely, is that System76 might 
for some reason have started with a Windows machine, not bare metal. 
Maybe that's why. 

> It appears like you took a large hard drive and set it up for some

I don't know what the friend did. The whole PC is now a backup; so 
I'd have no hesitation to DBAN it, install F32, and recopy data from my 
present #1 machine. I did think it seemed to have surprisingly little 
storage when I did that df -h; but if I understand better now, that 1.7T 
is real -- and, I hope, available for other uses. Is that so? Maybe I 
don't need to wipe it?

Don Norman? He did have a lot of influence on HCI design (or at least
he was cited a good deal). This is probably his best-known book:

If 'df' says that space is there, then you can believe it. Wiping it or
not is up to you, but a new install will be happier on a clean
partition (or in fact several partitions in order to keep /home
separate from root). However AFAIK the standard Fedora installer will
do this for you.

You have a point, altho not completely correct. Among the icons on my 
KDE screen,
the Package Manager looks like a wrapped parcel, two CD icons (K3b and 
Brasero)
sort of look like CDs, KCalc looks like a pocket calculator, sort of, 
KPatience card
games looks like playing cards. And Thunderbird, while showing a letter, 
has it
wrapped in a wig that covers where ears would be. Is that supposed to be 
feathers?

Anyway, one gets used to the image associated with a given app--much better
than have every app look like a manila folder--thanx to Microsoft for 
that! Even they

realized their error rather quickly.

Re: How do I change the grub kernel boot parameters in F32 ?

2020-06-09 Thread linux guy
This is pretty interesting because I am trying to fix a problem caused by
transitioning from nouveau drivers to the Nvidia drivers.  I installed the
Nvidia drivers but my system continues to boot the nouveau drivers.   If I
blacklist the nouveau drivers, my system boots and runs the Nvidia drivers
just fine.   The kernel parameters I want to add are for blacklisting the
nouveau driver.  (See above).

Re: Interfaces

2020-06-09 Thread Matti Pulkkinen

Tim via users kirjoitti 9.6.2020 klo 17.55:

the controllers on video games that I never play, there's nothing
sensible about why a game uses the square button, or the green
button, etc., it's all arbitrary.  They do nothing to contribute to
ease of use.
I don't know about you, but I can't think of an icon or symbol that 
would convey useful semantic meaning for a button which you sometimes 
use to jump, sometimes to activate a contextual action, sometimes to 
select a menu item, sometimes to shoot, sometimes to either crouch or go 
prone depending on how long you hold the button down, sometimes to apply 
gas in a car, sometimes to pass a ball to another player player, or 
whatever else. There are a limited number of buttons you can fit on a 
controller of reasonable size, and an unlimited number of potential 
in-game actions players may be able to take with said controller. I 
would argue that a four-button controller – perhaps labelled with 
arbitrary geometric shapes – contributes to ease of use much better than 
a controller with who knows how many buttons labeled with their precise 
in-game action. Since learning to play with a regular controller as a 
child, I've never actually had any difficulty in learning the controls 
to any game using such a controller. Playing with a controller becomes 
second nature, even if it contains arbitrary elements, because you just 
get used to it.


As for application and toolbar icons, usually after a while of looking 
at them, most will lose the metaphoric link between representation and 
reality, at least in my mind. In fact it didn't even register with me 
that the Files icon in Gnome is actually a filing cabinet until someone 
mentioned it earlier. It was just the symbol for the Files application.

It's possible that Windows was using that core for long enough that the 
kernel thought that it wasn't getting enough time.  Did you share all 
the cores with the VM?  That's not a good idea.

I just installed Fedora 32 on a machine 2 days ago, and had to install

the rpmfusion akmod-nvidia package, and the corresponding kernel entry
has this:

options $kernelopts

So it looks like the grubby issue has been fixed.

Not sure why the changes don't make it into grub.  If I blacklist nouveau

Re: How do I change the grub kernel boot parameters in F32 ?

2020-06-09 Thread linux guy
So both grubby and /etc/default/grub are set up correctly to run the nvidia
driver by blacklisting the nouveau driver.

But when I boot and edit the grub menu (with e), the kernal parameter
entries lack the blacklisting of the nouveau driver.

According to this page
https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/kernel-module-driver-configuration/Working_with_the_GRUB_2_Boot_Loader/
grub.cfg is generated from /etc/default/grub from anaconda and I'm only
supposed to run grub2-mkconfig as a last resort to regenerate grub.cfg.

This article must be out of date because my machine has neither
/boot/grub2/grub.cfg nor /boot/efi/EFI/fedora/grub.cfg

This confuses things even more.

See the reply from Adam Mercer.  He gives the whole command line argument.

As far as setting /etc/default/grub LINUX_CMDLINE args, those appear to 
be used by grub2-mkconfig, not grubby.

I used nVidia cards for over a decade with the drivers from rpmfusion 
and I never had to explicitly blacklist the noveau drivers.  I think 
that the best way to go is to install the drivers and see what happens. 
If they Just Work, leave well enough alone and Be Happy.  If they don't 
work right, then it's time to try things such as blacklisting.

re: Adam Mercer's suggestion:

grubby --update-kernel=ALL --args="rd.driver.blacklist=nouveau

Grubby is already returning the right kernel parameters.  Not sure why I
would need to run this.


re: As far as setting /etc/default/grub LINUX_CMDLINE args, those appear to
be used by grub2-mkconfig, not grubby.
So I ran this:

# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Generating grub configuration file ...
Adding boot menu entry for EFI firmware configuration
done

and it made no difference.

So I ran this:

# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Adding boot menu entry for EFI firmware configuration
done

Also made no difference.

Re: How do I change the grub kernel boot parameters in F32 ?

I've run Nvidia drivers since the RH8 days, back in the early 2000s.  Same
experience.  This is the first time I've had this issue.

I used linux in 2.0.X kernels (vintage 1998), and we used version=2,

So I guess that says no one outside of sun used version 1.
Hi Roger, earlier versions of Fedora (F28) supported version 1 of nfs as 
well as version 4 which they used by default, and I had to set nfsvers=1 
in the mount point in fstab to be able to mount my nas as it only

I seriously doubt there is any support for nfs 1 left
in the code (could be wrong).

Depending on random variations every time the nfs
utilities get updates, I've had to sometimes
specify "proto=udp" as well as or instead of
the nfs version in order to speak to antique servers.

Hi Tom, In another thread to Roger I've mentioned that in F28, and even 
though I didn't specify it, probably F30, Fedora used nfs4 by default 
which would not enable mounting of my nas, I had to specify nfsvers=1 in 
the mount instruction in fstab for the nas to be mounted, which now 
seems to no longer work. Following your suggestion I have tried 
nfsvers=3 and that has enabled the nas to be mounted. Now I have to try 
and figure out the right specification for the cifs mount point to be 
able to be mounted via the Windows share exposed by the nas. Thankyou 
for all your help.

It's possible that Windows was using that core for long enough that 
the kernel thought that it wasn't getting enough time.  Did you share 
all the cores with the VM?  That's not a good idea.
I did specify that the VM had access to 8 cores, as I wanted the VM to 
be able to time slice all cores if I was doing graphic intensive 
processes like photo editing, video playing or video format conversions 
if I could figure out how to drive ffmpeg properly.

Yes, probably something like that.  Typically, in order to schedule a 
virtual machine run time, all of the CPUs that the guest will use must 
be free simultaneously.  As you allot more CPUs to a virtual machine, 
that becomes harder to schedule, and the guest can experience greater 
latency between run time.  If your host system doesn't have at least 12 
CPU cores, I would recommend against allotting 8 to the guest.  Fewer 
cores will be easier to schedule, and may perform better.

I used nVidia cards for over a decade with the drivers from rpmfusion
and I never had to explicitly blacklist the noveau drivers.  I think
that the best way to go is to install the drivers and see what
happens.
If they Just Work, leave well enough alone and Be Happy.  If they
don't
work right, then it's time to try things such as blacklisting.

if in /etc/default/grub you have the entry GRUB_ENABLE_BLSCFG=true   , 
that inserts a line into the grub processes to use the new BLS standard, 
in which case grub2-mkconfig and possibly grubby do nothing until that 
entry is set to false. I have always use grub2-mkconfig because I have 
never liked what grubby generated, and what BLS generates appears to be 
the same as what grubby does, and I found that I had to set that entry 
to false for grub2-mkconfig to continue to work.

I think there is a file added to /etc/modprobe.d with the blacklist 
entry.  You need to install a new kernel or regenerate the initramfs 
using dracut for it to take effect at boot.

I've installed several kernels since changing to the NVidia driver.

I should have said "ls -l".  I'm just curious what that is.  Can you do 
"file /.snapshots/alpha.0" and if it's a directory, do "ls -la 
/.snapshots/alpha.0""?


To find out how it's getting mounted, do "mount | grep snapshot" and 
"cat /etc/fstab". (You don't need to include the whole thing, just see 
if there's a relevant line in there.)



Also, what about "lsof /.snapshots"?


# lsof /.snapshots
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/65536/
gvfs
   Output information may be incomplete.

It says "incomplete"; but the lines above are its whole output.


Yes, you can ignore that warning.


It appears like you took a large hard drive and set it up for some
backup system, but I have no idea what one would work like that.


I don't know what the friend did. The whole PC is now a backup; so
I'd have no hesitation to DBAN it, install F32, and recopy data from my
present #1 machine. I did think it seemed to have surprisingly little
storage when I did that df -h; but if I understand better now, that 1.7T
is real -- and, I hope, available for other uses. Is that so? Maybe I
don't need to wipe it?


If there's nothing important on the computer or the hard drive, I would 
suggest reinstalling it.  You can use the SSD for the root filesystem 
and put /home on the big drive.

Some random suggestions.  I don't run nvidia anymore so never have
problems like this, but maybe one of these will at least give you some
insight to what is happening.

F32 should work with GRUB_ENABLE_BLSCFG=true since it is the default
for new installs.  Can you set it back to true and then run the
mkconfig for efi again.  Once you do that, can you show the output of 

cat /boot/loader/entries for the .conf file for the 5.6.16-300 kernel

Then show the line in /boot/efi/EFI/fedora/grub.cfg that has kernelopts
in it.  If the kernel options you want aren't in that line, I don't see
how they will get to your kernel.

I know whether the system is booting efi or not because a message comes
up during boot, before the selection menu, that says something like
using efi secure boot
I have rhgb and quiet turned off, though, so I see that message.  I see
you have them turned on.  If you remove them, there might be a clue to
what is happening in the kernel messages.

Does anything show up as an issue if you do a
journalctl -b
and go to a boot that didn't have the parameters you want?

Try reinstalling the nvidia packages from rpmfusion after you generate
a new grub.cfg, and forget about the nvidia options, to see if it will
install correctly the way it always has once you have a grub.cfg file (I
think you said initially you didn't have one).

What happens if you use the efi firmware boot menu to try to boot using
efi?
