Description of problem: A minute or two after loging into graphical environment, my system hangs. The concrete behaviour is: 1) If I log into default KDE session, after a while the screen freezes, there is no response to mouse or keyboard - although the keyboard is not completely dead, the sysrq key combos work (after enabling sysrq via configfile in /etc/sysctl.d/ of course). 2) If I log into X11 KDE session, after a while the screen goes black. The keyboard responds somehow - pressing e.g. capslock changes the capslock light state (it does not happen in the above case), but I cannot switch to another (text) console or whatever. (Sysrq works too, of course.) 3) If I do not log into graphical environment via sddm, but rather switch to text console and use `startx`, the graphical KDE session starts and keeps running without any problem. Looking into logs just before the hang, it is highly suspicious that it says it is starting session while a session is started already bře 21 10:21:26 kvolny sddm-helper[4439]: Starting X11 session: "/usr/bin/X -nolisten tcp -background none -seat seat0 -noreset -keeptty -novtswitch -verbose 3" "/usr/bin/sddm-greeter --socket /tmp/sddm--iGfpta --theme /usr/share/sddm/themes/01-breeze-fedora"
This happens every other boot for me. Fedora 36 KDE
I have the same problem.
New information. I can connect to hanged system via ssh. See that kwin_wayland load one core to 100%.
I can reproduce. I downgraded to latest stable SDDM (sddm-0.19.0-19.fc36.x86_64) and the problem doesn't seem to occur. There was also a black screen delay for like 10s when I typed my password and clicked to log in and only then I could see Plasma loading, this doesn't happen with the stable version.
Proposed as a Blocker for 36-final by Fedora user vascom using the blocker tracking app because: KDE spin crashes because of non stable sddm version. This made F36 KDE fully unfunctional. Workaround now is downgrade sddm to last stable version.
Does mesa-22.0.1-1.fc36 (updates-testing) fix totally/partially this issue ?
With mesa-22.0.1 still the same problems.
Can folks affected by this report the output of: rpm -qa | grep sddm please? Thanks!
sddm-breeze-5.24.3-3.fc36.noarch sddm-kcm-5.24.3-1.fc36.x86_64 sddm-0.19.0^git20220228.c257a40-4.fc36.x86_64 sddm-x11-0.19.0^git20220228.c257a40-4.fc36.noarch sddm-themes-0.19.0^git20220228.c257a40-4.fc36.noarch
If you replace sddm-x11 with sddm-wayland-generic (you may need to use dnf swap, not sure) does the problem go away?
After that I see just black screen instead of sddm. But if I switch to Ctrl+Alt+F3 I can login to console. At top sddm-greeter use ~1% of one core and it on the top.
Hi, I can confirm this issue as well. Upgraded my Fedora 35 Kinoite installation to version 36-beta, by running `rpm-ostree rebase` and rebooting the system. After entering my username and password, it took much (about 15s) longer before the desktop appeared, compared to Fedora 35. Then after 1-2 minutes, the desktop hangs and is unresponsive to my keyboard and mouse. I was able to login my system using SSH (during this freeze), reboot and selected the previous Fedora 35 slot. Then I ran `rpm-ostree rollback` and in Fedora 35 everything works fine again. Kind regards, Sander de Leeuw
I've built a new git snapshot of SDDM which includes the merged version of the fix for another bug that seems like it might help here, does it help with this issue? https://koji.fedoraproject.org/koji/buildinfo?buildID=1942317

Hungs is absent at least for wayland session. But very long time black screen before KDE desktop show (about 30s) still present.

Can folks try this scratch build? https://koji.fedoraproject.org/koji/taskinfo?taskID=85124690
That build works fine.

I believe this is the same bug as bug 2070130.
