F24 - Blank Screen presented at SDDM
by Gerald B. Cox 26 Jun '16

26 Jun '16

I've noticed something strange and was wondering if anyone might have clues as to what is going on. I have a Lenovo ideapad with a radeon chipset. Everything appeared fine with F23 - but when I upgraded to F24 I started having issues getting a blank screen instead of the KDE login prompt screen from SDDM. If I boot into single user mode, and then issue an init 5 command, everything works fine. Any idea as to what this might be? I would think if it were a display driver problem the init 5 wouldn't work either. So to recap: Normal boot - blank screen Single user mode, followed by init 5 - everything works. Thanks!

New install freeze
by Robin Laing 25 Jun '16

25 Jun '16

Hello, Trying to run F24 KDE Live on a new machine. Never been used before, it's that new. Install checks the install medium with no issues but freezes after EDAC sbridge - Couldn't find mci handler. This was followed by kvm - disabled in bios. which was fixed by turning on VT in the bios. Motherboard is an ASUS X99 Sabertooth with latest BIOS. Processor is an i7 nVidia Titan X video card using HDMI output or DVI. Fedora 23 wouldn't even boot due to an X.509 error. I need to use secure boot as this will be a dual boot with Windows 10 for some games that won't run in a VM. Right now, I just want to get Fedora running on the machine. I would be happy with F23. I have left the machine in this state for almost an hour with no changes. Downloading basic Fedora now. Robin

Two Problems Upgrading From F23 To F24
by Garry Williams 25 Jun '16

25 Jun '16

I upgraded to Fedora 24 (from Fedora 23) and had two problems: The upgrade apparently deleted kdm and did not enable sddm as my login manager, so no graphical login. A "sudo systemctl --force enable sddm.service" corrected the problem. Oh well, I guess I should not have continued with kdm so long. :-) Kmail ignored my settings[*] and created settings as if I never had any. It _did_ know where my mail was. I had to copy kmail2rc from ~/.kde/share/config to ~/.config . All is well now. ___________________ [*] This is quite irritating since the KDE developers have been doing this sort of thing with the entire suite over the last several years. They have shown a complete disdain for users' settings for all of the KDE desktop applications and environment. It is amazing to me that it still goes on. -- Garry T. Williams

F23 KDE stability issues
by CLOSE Dave 24 Jun '16

24 Jun '16

Apologies if you've already seen this note which I previously sent to the general Fedora list. I'll be the first to admit that I don't use Fedora in a conventional way. But it suits me -- or it did until things started misbehaving a few weeks ago. Now I'm finally disgusted enough to write some notes and hope for good advice. I run F23 with the KDE desktop in what used to be called runlevel 3. I delete rhgb and quiet from /etc/default/grub and start X using startx because I like to see what happens during boot. I hate systems that try to hide what is really happening. Once KDE is running, I use eight desktops with several windows on each one, most of them XTerms with active SSH sessions to other machines. When I leave my desk, I lock the screen (using the default KDE locker as configured with System Settings) but I disable locking based on inactivity. As long as this works, I'm happy. But it doesn't work reliably for the last few weeks. If I'm away from my desk for more than a few minutes, the lock screen is frozen when I return. I can't unlock. I can switch to a different virtual terminal and kill X, but if I then try to restart X using startx again, it doesn't come up properly. No windows appear, no panels, and neither the keyboard nor the mouse do anything except move the cursor. I have to fall back to rebooting. When I reboot and startx again, things start up as they should. Except that all my previous windows are on the first desktop, overlapping like crazy. Moving them where they should be is very annoying and tedious. I have to do this at least once per day, sometimes more often. It's not just a matter of rearranging the windows, I also have to re-establish all the SSH sessions. And, of course, any active commands that were running were terminated so I may have some clean-up to do, also. My machine is completely up-to-date with the latest Fedora. Even the kernel is up-to-date due to the frequent reboots. The F23 was not an upgrade, it was originally installed fresh using the workstation image (but choosing KDE, not Gnome). -- Dave Close

Proper way to configure HiDPI font & icon scaling?
by r.green＠officeserve.com 24 Jun '16

24 Jun '16

The way to configure HiDPI font and icon scaling in KDE has changed at least a couple of times: (Note: Some programs, such as Chromium and Java, ignore all these settings and have to be configured independently.) 1. In the original implementation of HiDPI support for KDE, as documented in blog posts by KDE developer David Edmundson, it was necessary to set both "force font DPI" - for fonts - and "scale display" - for everything else. 2. In January when I first installed Fedora 23, setting both "force font DPI" and "scale display" produced unexpected results - I eventually figured out that in fact, it worked much better if I just set "scale display" to 2. 3. I've since changed jobs and installed Fedora 23 on a new laptop, and with all the updates installed, it's again necessary to set both "force font DPI" and "scale display" for everything to be legible without squinting. But this it's undesirable to set both, because now with both set, most KDE applications have huge fonts. Non-KDE applications like Thunderbird look OK though. Some possible clues as to why this has changed again: Clue 1: If I leave "force font DPI" unset, it's actually set to 0 in a config file, and the fonts are really tiny, suggesting that 0 is being interpreted as "very small". Clue 2: I now get these messages when I run a KDE application from a konsole: Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use: QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors. QT_SCREEN_SCALE_FACTORS to set per-screen factors. QT_SCALE_FACTOR to set the application global scale factor. So I'm guessing that Qt has been upgraded to a newer version, but KDE hasn't been updated to take account of the changes mentioned above. Since they are environment variables, it looks like I can set them myself without needing to wait for KDE to be fixed. So how should I set them? -- Robin

plasma-5.6.5 updates
by Rex Dieter 19 Jun '16

19 Jun '16

Now that F24 release is imminent (and freeze to be lifted), updates can start flowing. First up: plasma-5.6.5 Is now available in kde-testing repos, and queue'd for updates-testing: f24: https://bodhi.fedoraproject.org/updates/FEDORA-2016-541d258919 f23: https://bodhi.fedoraproject.org/updates/FEDORA-2016-58fb569ef8 autokarma is disabled to be on the safe side. I'll be largely unavailable next week, so other kde-sig members can decide when/if to push stable (if you don't want to wait on me). Coming soon after: KDE Frameworks 5.23.0, KDE Applications 16.04.2, Qt 5.6.1 -- Rex

firewall-config not functional
by Emmett Culley 19 Jun '16

19 Jun '16

I first posted this to the Fedora list, it then devolved to a nice discussion on NetworkManager. I now believe I should have posted it here first. ----- I have a number of machines (hardware and VMs) running CentOS 7 and KDE. In all cases firewall-config is not functional. First, the service check boxes are not functional. When you click on one, it don't change to "checked", and nothing changes on the firewall. However you do see a "Changes applied" in the status bar at the bottom. Sometimes, if you go to permanent mode and attempt to edit a zone, the whole desktop locks up as soon as you click on the default target dropdown. This only happened twice. When I run firewall-config from the command line I see the following: -------------------------- org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.NetworkManager was not provided by any .service files (firewall-config:5079): Gtk-CRITICAL **: gtk_tree_view_get_path_at_pos: assertion 'tree_view != NULL' failed -------------------------- with the second line repeating many times and often while attempting to interact with the GUI. We don't use NetworkManager except on laptops, and so do not install it. Though we do install NetworkManager-glib, if only because some packages require it. After seeing a similar bug on the RHEL I also installed NetworkManager-libnm, but that did not make a difference. That RHEL bug also mentioned this problem only occurs on KDE, and not Gnome. And we only install KDE when a GUI is required, or desired. Emmett

F23: System Load: Application memory calculation
by Terry Barnaby 16 Jun '16

16 Jun '16

Is the KDE/Plasma "System Load" calculation of application used memory correct ? Currently on my system the KDE "System Load" panel widget shows 11.3G of memory used by applications in a 24G memory system. ksysguard is the same. /proc/meminfo shows: MemTotal: 24689476 kB MemFree: 1081276 kB MemAvailable: 20106752 kB Buffers: 4722180 kB Cached: 7071252 kB SwapCached: 4156 kB Active: 8374976 kB Inactive: 6882576 kB Active(anon): 2623148 kB Inactive(anon): 1005372 kB Active(file): 5751828 kB Inactive(file): 5877204 kB Unevictable: 32 kB Mlocked: 32 kB The "top" program states 4G used which matches the /proc/meminfo. So the 11G seems incorrect...

krunner currency conversion
by Mattia Verga 16 Jun '16

16 Jun '16

In the past I used krunner to make on-the-fly currency conversion (alt-f2 -> type "1$" and get Euros or Pounds). Now it seems that this function doesn't work anymore: I can make other unit conversions (gallons to liters, meters to miles, etc.) but currency conversion does not work. Anyone knows why? I cannot find anything in configuration to enable or disable that. Thanks Mattia
