SUMMARY Fresh install OpenSuse Tumbleweed. Plasma 6.2 - X11 Session: When locking the session (Meta+L) the screen goes completly black with only a cursor. Upon turning monitor off and back on again the lock screen appears, when logging in icons on desktop are scrambled. Turning monitor off without locking and turning it back on results in same blackscreen. Plasmashell can be restarted then with opening a Konsole window via shortcut and running "killall plasmashell && kstart plasmashell" and desktop is back but icons are scrambled. STEPS TO REPRODUCE 1. login x11 session 2. lock session 3. turn monitor off - and back on again 4. log back in OBSERVED RESULT after lock session the screen is black, it comes back when monitor is restarted but after login the desktop icons are scrambled EXPECTED RESULT the lockscreen shows and remains after monitor off/on + the desktop icons remain in position. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.2 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.3
Ok issue seems not not happen everytime. sometimes the lockscreen actually appears, when the blackscreen appears waiting does not resolve it though even after 10min the lockscreen wont appear. Same for the monitor off/on cycles - sometimes the desktop comes right back. sometimes plasmashell seems to be frozen entirely (nothing in panel or desktop can be clicked but window shortcuts still work) either way turing monitor off/on again couple of times seems to cause plasmashell to come back and work normaly again. Anyway lockscreen (and desktop icons) unusable in X11 session with auto monitor sleep
Created attachment 174579 [details] kwin_x11 crash - added kwin crash dump: maybe related, maybe not but kwin_x11 crashes when monitor is turned off while no app is running. when at least one window is open the crash dialog does not come up when plasmashell shows up again display is connected via displayport to dedicated amd gpu, there is no second monitor shenanigans or any weird monitor setup, simple FHD (1920*1080) resolution and no other connection is used.
The kwin crash should be fixed with https://invent.kde.org/plasma/kwin/-/merge_requests/6582
I swear i try to search for existing bugs before i create new ones but i somehow missed this, probably cuz it was under theme component and didnt have "black" screen in it but its exactly what is happening on a fresh tumbleweed install when u change the theme to Breeze, wich is the only thing i did (always do this, to avoid distro themeing and rather use the KDE defaults) buit when changing back to the distro theme the blank/black screen does not appear. only with breeze theme: so that part is duplicate of this unresolved bug: https://bugs.kde.org/show_bug.cgi?id=483163 the desktop icon scramble sounds very much like this resolved bug: https://bugs.kde.org/show_bug.cgi?id=493569 which either is not resolved or triggered by a different issue, it happens everytime u cycle monitor power though just like described in that bug. Let me know if i should close this one as duplicate and reopen that one.
Some questions: 1. Can you upgrade to Plasma 6.2.1, then move and rename one item (to force a config refresh) and see if it still happens? 2. If it still happens, can you also try on Wayland to see if it happens there? 3. Regardless, can you comment on the number of monitors you have? If it's more than one, can you try with only one monitor and see if it still happens? Thanks!
Oh and one more question, if you don't mind: 4. For the monitor where you can reproduce the issue, how is it connected?
Both bugs still happen on 6.2.1, but this can be closed as duplicate as its exactly the 2 bugs i linked and those include more info. 1st bug (missing lockscreen) is only happening on X11 and with compositor turned on and is fixed with choosing different theme (note opensuse theme seems to be 1:1 breeze with just a different default desktop wallpaper) 2nd bug (scrambled icons) is happening on both wayland and x11 - but not after chaning default sort order to "top to bottom" its a single monitor connected via displayPort directly to dedicated amd gpu in a desktop-pc (no other gpu).
the kwin_x11 crash issue i thaught connected to bug 1 is fixed in 6.2.1 though.
When the icons become "scrambled", do they reset to alphabetical order? Or is the order they appear in something different? If it's alphabetical order, this is Bug 482875.
Never mind, it's only alphabetical the first time; after that it's random-looking. So yeah, this is Bug 482875. *** This bug has been marked as a duplicate of bug 482875 ***
