https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #7 from Tito --- As of right now it just crashed to the login manager a few seconds after i try to login. although i dont really know if i did the stuff right, heres it what i did: applied the pach using the file provided. compiled and installed it following this as refernece: https://community.kde.org/KWin/Building installed a fresh copy of both plasma-meta and kde-applications-meta just to exclude any other possibilities of errors tried both with and without the edit to the env file as suggested in the previous link thanks for the help! -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #9 from Tito --- i followed the second method, and the result was pretty similar. the screens connected to the intel igpu behaved like shown before, tho after the loading of the logo finished, the desktop remained black, and any attempt at restarting/logging out trough the ctrl+alt+canc menu lead to weird and inconsistent behavior like poweroff or restart. should i try the first method? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #11 from Tito --- This patch seems to behave a bit better: First try the two screens connected to the igpu didnt have any graphical issues, although i didnt managed to go all the way to the desktop as it stalled to a black screen with the cursor, this time the ctrl+alt+canc menu behaved correctly logging me out without any problems. at a second try the two screens connected to the igpu were black (the screen was off) as they didnt recived any signal and went to power saving mode. the rest behaved as stated before. on this last try i also got a weird behavior as i heard the cpu fan spin up while logging out of kde, when i went back to check the cpu usage was at 100, any graphical resource monitor couldnt tell me which program was cousing this, except for htop wich showed some programs at around 260% cpu usage, killing the process fixed this. sadly i didnt noted the names of those as i thought they werent the cause of the issue. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #14 from Tito --- Attached the log file to the thread. This time the behavior war different, the two screens black from no signal, no deskop, but yukuake was working and applications opened from the console too (chromium). i dont thin this matters at this point, tho it might be worth mentioning. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #15 from Tito --- I might add that i got the same behavior with the cpu usage, and the top cpu intensive programs are this. as i never got anything like this, might this be another bug with the beta or the patch? https://imgur.com/R62OXCc These are my top cpu intensive programs after logging out of plasma -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #19 from Tito --- Great progress! Now it kinda works, i still have problems with plasma, as i cant really get to the desktop, but thanks to the drop-down terminal i can run something like chromium and move it in to every monitor to see if it works or not: https://imgur.com/a/kpFr1uU link shows the glitches on the screens connected to the Igpu, also the logout plasma crash is back. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #21 from Tito --- it gives me some compilation errors and it stops. i did the same thing for the previous patches, might it be a but in the code? kwin/build/plugins/platforms/drm/KWinWaylandDrmBackend_autogen/EWIEGA46WW/../../../../../../plugins/platforms/drm/egl_gbm_backend.h:49:10: error: ‘void KWin::EglGbmBackend::cleanupDmabufForSecondaryGpuOutput(KWin::AbstractOutput*)’ marked ‘override’, but does not override 49 | void cleanupDmabufForSecondaryGpuOutput(AbstractOutput *output) override; this seems to be present a few times while compiling, might it be the couse? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #25 from Tito --- Thanks so mutch for the help! I've been trying to install and compile everything from source with kdesrc-build, but i ran in a lot of dependencies even after following this guide https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Install_the_dependencies and installing the suggested packages. I ran in this package kross that wouldnt install, and now im stuck on this step. am i doing something wrong? seems that its not a problem of dependency... -- You are receiving this mail because: You are watching all bug changes.
