Hi, I am running F42. I have been trying the betas from @kdesig/kde-beta. All worked perfectly as far as a beta is supposed to be (actually the only issue was that the mallik (spelling?) keyboard was crashing frequently. After the update to qt 6.9.1 and on the next reboot sddm crashes on start: Stack trace of thread 1594: #0 0x00007fde0ac8111c __pthread_kill_implementation (libc.so.6 + 0x7311c) #1 0x00007fde0ac27afe raise (libc.so.6 + 0x19afe) #2 0x00007fde0ac0f6d0 abort (libc.so.6 + 0x16d0) #3 0x00007fde0ac106f3 __libc_message_impl.cold (libc.so.6 + 0x26f3) #4 0x00007fde0ac8b275 malloc_printerr (libc.so.6 + 0x7d275) #5 0x00007fde0ac9060c free (libc.so.6 + 0x8260c) #6 0x00007fde0bae3370 _ZL13init_platformRK7QStringS1_S1_RiPPc (libQt6Gui.so.6 + 0xe3370) #7 0x00007fde0bae628b _ZN22QGuiApplicationPrivate25createPlatformIntegrationEv (libQt6Gui.so.6 + 0xe628b) #8 0x00007fde0bae6e88 _ZN22QGuiApplicationPrivate21createEventDispatcherEv (libQt6Gui.so.6 + 0xe6e88) #9 0x00007fde0b3027ad _ZN23QCoreApplicationPrivate4initEv (libQt6Core.so.6 + 0x1027ad) #10 0x00007fde0baeb48d _ZN22QGuiApplicationPrivate4initEv (libQt6Gui.so.6 + 0xeb48d) #11 0x00007fde0c643aa5 _ZN19QApplicationPrivate4initEv (libQt6Widgets.so.6 + 0x43aa5) #12 0x00007fde0e16c9e7 _ZN4KWin11ApplicationC1ERiPPc (libkwin.so.6 + 0x16c9e7) #13 0x0000559ffbf61851 main (/usr/bin/kwin_wayland + 0xd851) #14 0x00007fde0ac115f5 __libc_start_call_main (libc.so.6 + 0x35f5) #15 0x00007fde0ac116a8 __libc_start_main@@GLIBC_2.34 (libc.so.6 + 0x36a8) #16 0x0000559ffbf69c55 _start (/usr/bin/kwin_wayland + 0x15c55) ELF object binary architecture: AMD x86-64 While searching for this I noticed a similar report on Arch where supposedly the cure was to rebuild the plasma packages with the new qt6 version: https://bbs.archlinux.org/viewtopic.php?id=306023 FWIW the symptom is that sddm crashes. The workaround for me was to open a tty terminal, launch the gdm service and log in to gnome (plasma naturally fails). Is this information helpful?
