I came up with a slightly different answer, which also works. I'm just documenting it here for reference. I copied debug-shell.service from systemd to /etc/systemd/system/root-shell.service. I modified the file as below because I wanted to start a root shell on /dev/console, and I also wanted the target to be multi-user.target. I then enabled the service as usual: # systemctl enable root-shell On boot, it starts a root shell with no login required.

What I don't know is which specific updates have reintroduced the issue as I have only just noticed it. How do I identify whether this is an upstream issue or whether Fedora changes have caused the issue (I think changes to KDE Themes can cause this as well). From what I can see, this is (has) been an issue in kde-workspace in versions prior to 5.6.5. Verify the versions you have installed via dnf list installed kde-workspace* If it's later than 5.6.5, then you should probably bugzilla it to Fedora. Make sure you put all the pertinent data (KDE component versions, themes versions, etc.) in your report. The Fedora gang will see if it's something Fedora-specific. If not and it's from upstream, I think they'd push it up the food chain to KDE. Thanks for the response Rick. I issued the command and the only response I got was for kde-workspace-common.noarch which listed the version as 1:4.11.22-16.fc24.

I understand that, however the issue isn't that Steam doesn't work, but that some FPS-type games are too laggy to be usable, i.e. the problem is performance rather than function.

Developing Android apps under Fedora/KDE
I have an old smartphone (Samsung Galaxy S2), unlocked, and I'm thinking of trying to write simple apps for it on my Fedora-24 laptop. I'm fairly familiar with Java (and Eclipse) (Long ago I wrote a program modifying TeX web2c to output Java). I haven't found a reasonably authoritative article on this, and would welcome advice and/or suggestions from anyone who has gone down this route. I ran "dnf search android" and found quite a few appropriate sounding programs, but found it hard to tell how they would fit together. I'd like to do it in as simple and standard a way as possible, eg not writing in C++ and using a program to translate that to Java. I've looked at a number of sites claiming to teach this topic, but none of the ones I have seen had concrete instructions of how to transfer Hallo World, say, to the phone and run it there. And all seemed to have their own special programs, eg I was just looking at one which said "Android Studio is the official IDE for Android development" but none of the others mentioned this program (or suite). As I said, I would be very grateful for any knowledgeable adivice on this topic. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org

I have looked quickly through your long article, and will probably follow your advice. I find your hatred of Eclipse (that is what I assume you are talking about) slightly off-putting, as you seem to imply that all other works on the topic recommend it. I'm not particularaly fond of Eclipse, but not to the extent that I won't use it if it is recommended. It does come slightly between you and the app you want to write, but is it any more than the other programs you recommend? However, I suppose the issue that most worries me is this: Is developer.android.com the official Android site as they claim to be? Eg is it supported by google? And is studio the official Android IDE? Official as defined by who? Incidentally, I looked (quickly as I said) through your book/article, but didn't see anywhere where you explicitly said how to transfer your app from emulator to phone. Do you explain that somewhere, or do you consider it obvious? Again, does one have to have root access on the phone?

F23: KDE menu launch SSH inside konsole fails after update
I don't know when it stopped working working, but it was recently. Unfortunately, with almost daily updates I don't know what's caused it. I have menu entried within my KDE which start a ssh command inside a konsole. This has worked fine for as long as I can remember (F9 or before) However, now when I try, I get the launch feedback, the konsole window never opens. If I open a konsole session, e.g. by right clicking the desktop, and then run the ssh command then all works fine. Can annyone suggest how I can debug/fix the problem? ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org

Yep, that's the official google site. They have their own tutorials out there as well to guide you through developing example apps with android studio. > Incidentally, I looked (quickly as I said) through your book/article, > but didn't see anywhere where you explicitly said > how to transfer your app from emulator to phone. > Do you explain that somewhere, or do you consider it obvious? > Again, does one have to have root access on the phone? > Is that discussed in your article? I probably didn't think about it. What I mostly did was setup a directory on my desktop's web server where I copied the .apk files so I could download them on the phone via a web browser. You don't need root, but you do need to enable the "allow install from any source" over in settings so it will let you install the downloaded .apk file. You can certainly install them with a USB connection and adb commands though rather than downloading them over wifi. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org

Nah, it is just personal preference. I found it more convenient to download them via a web browser (which I already had setup and running) rather than fool with USB cables, but I think adb can do the install directly rather than a two stage download then install, whatever works for you. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org

Yes. I enabled hibernation months ago and it worked up until fairly recently (2 or 4 weeks roughly). Hence my conclusion that the Nvidia drivers have something to do with it. Unfortunately Googling the issue doesn't show up anything useful. If I kept notes of significant changes (or could understand the systemd journal) I could probably pin it down, but that's a big ask. I suspect many of us are in the same position. As I said, I'm happy enough with suspend for now.

kde plasmashell eating cpu - FC24 all updates on INTEL Q6700
I have just discovered (one of?) the reasons plasmashell was eating so much cpu and memory on my system. I have dual monitors and in circa FC20 I could get a panel on both screens then something happened (and I suspect I tried apparently unsuccessfully to restore a panel to one of the screens) and pretty well from then on the plasmashell problem grew. After looking on the kde lists for a clue as to what the problem might be (I notice its a "well known bug") I espied recently a comment about someone deleting a panel and finding there was another panel underneath So I deleted the panel on the screen that had one - lo' it was "still there" - I deleted that . for about 10 of them! The last one disappeared - but I could restore it (undo the delete) Now with just one panel my kde desktop has finally reverted to sanity after about 6 months! I will now try to work out exactly what happened and when it happened.
