Hello everyone,
Yesterday I updated both my PC and laptop and it pulled in kde-plasma/kwin-6.5.5-r2. After this I started to notice that my whole plasma session crashes at initial startup, when clicking anywhere on the desktop or on the KDE logo or any icons on the desktop. Everything disappears for a second and then re-appears. I was wondering if anybody else encountered this issue recently and might have a solution This happens both on my laptop (Intel iGPU and NVIDIA dGPU) and my desktop (NVIDIA dGPU).
Since I'm experiencing this on both of my machines, I've also generated a bug report: https://bugs.gentoo.org/969811
kwin-6.5.5-r2 crashes after upgrading to the -r2 release

I've had the same issues recently on my amdgpu driver system with Wayland. The plasma session starts, and then crashes to a black screen with a cursor. Switching to any VT other than F1 will kill all of the VTs. I don't have the problem if I use X11 instead of Wayland as the display server.
The only clue the logs have shown me so far is "drmSetMaster failed: Device or resource busy" when it happens. Searching online, it seems multiple folks are encountering this issue with different drivers and different session setups. They all seem to be converging on some sort of race issue with the auto-reconfiguration of the fbdev and the modesetting drivers. It's random and intermittent, and started sometime within the past few weeks. I haven't had a chance to debug it further. If I can get it to consistently repeat I'm going to try pulling fbdev out of the kernel and see if that helps any.

It looks like some kind of a race condition. I also got black screen with a cursor several times, but it was still possible to log in without issues on another VT after that. And it's enough to wait a couple of seconds after prompt to enter login appears to avoid this 'empty blackness'. I use OpenRC, amdgpu driver and don't use any display manager.
Me too.
I see the following in my stdout for the startx command (or rather, my own equivalent thereof):
There's a Qt bug (with nobody taking any action) , though it's for Dolphin and may just mean it's irrelevant (why does KDE write so much cr*p to stdout and nobody bothers to fix the error messages? 
).
Then a trifle later:
Google Gemini reckons (slightly edited by me):
I see the following in my stdout for the startx command (or rather, my own equivalent thereof):
Code: Select all
kf.kio.core.connection: Socket not connected QLocalSocket::PeerClosedError
kf.kio.core: An error occurred during write. The worker terminates now.
QThreadStorage: entry 6 destroyed before end of thread 0x55e8bb7ce820Then a trifle later:

qt.dbus.integration: QDBusConnection: couldn't handle call to Teardown, no slot matched
qt.dbus.integration: Could not find slot Krunner1Adaptor::Teardown
qt.core.qobject.connect: QObject::disconnect: Unexpected nullptr parameter
(EE) failed to write to Xwayland fd: Broken pipe
The X11 connection broke (error 1). Did the X11 server die?
X connection to :0 broken (explicit kill or server shutdown).
The Wayland connection broke. Did the Wayland compositor die?
qt.qpa.wayland: Attempting wayland reconnect
This seems to be on the basis of a discussion on the Arch Linux forums, with solutions:Based on the error logs provided, this issue represents a collision between Qt6/DBus components during session termination or suspension, specifically involving KRunner and Xwayland. This frequently results in a momentary black screen or a crash to the login screen.
...
This is a known, recent issue related to Qt6 and DBus updates in KDE Plasma. A full system update or reinstalling qt6-base and plasma-workspace typically resolves it.
Analysis of the Errors
qt.dbus.integration: Could not find slot Krunner1Adaptor::Teardown: KRunner is trying to call a "Teardown" method, but the slot does not exist in the current adaptor. This indicates a mismatch between the running KRunner binary and the adaptor definition (often due to partial updates).
(EE) failed to write to Xwayland fd: Broken pipe: The Xwayland server (which allows X11 apps to run on Wayland) has closed its end of the connection, causing a crash
- If you are on Arch Linux or a similar rolling-release distribution, this is often caused by a partial upgrade where the plasma-workspace or qt6-base packages are out of sync.
- Wayland/NVIDIA Driver Issues - If this happens when waking up, closing a game, or turning off the screen, it may be related to driver conflicts with Xwayland.
- If KRunner keeps crashing, you can temporarily disable it to confirm it is the source of the Teardown error: Go to System Settings > Search > KRunner and disable it, or stop the service via command line.

Hello, this might be fully unrelated but downgrading mesa 25.3.X to mesa 25.2.X (updated around Feb 11 for someone in another topic, around Feb 9 for me) solved his gnome crash on log in. It also solved my external monitors not working anymore. He has an AMD GPU, I have an NVIDIA GPU so it appears to be mesa-specific.
I didn't reinstall Mesa 25.3.3 to troubleshoot further, but I don't remember seeing nouveau drivers initialized in dmesg with this mesa-25.3.3 or mesa-26.0.0 (and I do see it with mesa-25.2.8). I also remember messages about compositor crashing on screen allocation because EGL wasn't initialized yet.
This does not appear to be incompatible with the race condition (this new mesa version lazily starts EGL; leading to EGL being used prior to its initialization on kwin/gnome-shell/others... ?)
Why is it initialized after a first crash on KDE ? (it seems like this initialization does not happen at all on [gnome-43 || sway-1.11 || hyprland] && mesa-25.3)
This could also be fully unrelated...
I can provide more debugging logs later if it is helpful

There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors.

Just some more debugging. This is an intermittent problem that seems to appear mostly when doing a system reboot. I haven't seen a power-off / power-on cycle trigger it. Happened again on today's upgrade to stable kernel 6.18.12-gentoo.
Tried removing the framebuffer driver (/dev/fb0) from the kernel. Still crashed, so rebuilt it back in as a module. Still crashed.
System Info:
/var/log/sddm.conf shows this on a failed startup:
The log above shows sddm dies trying to start the X server (Xwayland). /var/log/Xorg.0.log shows:
The Xorg log shows that things start going wrong at "(EE) AMDGPU(0): [drm] device is not DRM master.", AMDGPU(0) becomes modeset(0), and it goes sideways from that point on.
Trying "rc-service display-manager restart" usually succeeds in killing all the VTs at this point and ALT-PRTSCR-S/U/B is needed to reboot.
After more reboots, eventually X succeeds and that looks like this in sddm.log:
And in Xorg.0.log:
So far neither google nor its AI doppelganger have pointed me to a reason why X is failing to recognize my AMD video card randomly after a reboot, when it had no problem doing so before. I'm running OpenRC not systemd, and I haven't used (or needed) an xorg.conf file for a few years now, and twiddling with those two things are the most commonly recommended options.
BTW, the successes always happen when sddm tries to start X on vt2, and the failures when it tries to launch on vt7. There's this forum post:
https://forums.gentoo.org/viewtopic-t- ... rt-0.html
and this bug report:
https://bugs.gentoo.org/913862
However, no one seems to know exactly what's going on. The debugging continues...

BTW, the successes always happen when sddm tries to start X on vt2, and the failures when it tries to launch on vt7. There's this forum post:
https://forums.gentoo.org/viewtopic-t- ... rt-0.html
and this bug report:
https://bugs.gentoo.org/913862
However, no one seems to know exactly what's going on. The debugging continues...
