https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #26 from Zamundaaa --- I honestly skipped installation of dependencies and just built things with kdesrc-build and installed non-KDE dependencies as needed. No idea if that could lead to problems but worked fine for the last year or so. If you have some sort of beta repository installed then I guess that could make problems with installing kross. I don't think it should matter though, you can just build it as well with kdesrc-build ¯\_(ツ)_/¯ -- 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.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #24 from Zamundaaa --- Thank you so much for your patience and testing! The patches are up and should get merged soon. For the problem with the desktop not starting (or crashing) you should make a bug report for plasmashell, although it's probably been fixed already and just not in the beta yet. If you're too impatient to wait for the release of 5.21 and the beta doesn't get updated with fixes then I would recommend you to compile a complete session with kdesrc-build. While it can take quite a while for the first run, everything currently works fine on master. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #20 from Zamundaaa --- I believe those glitches are caused by missing VSync, which should be fixed by https://invent.kde.org/plasma/kwin/-/merge_requests/642. If you could test that as well that would be very nice.

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 #17 from Zamundaaa --- Hmm so I did find some more information on the function I was using and one's not supposed to use it directly, it'll only cause problems. I'm rather confident to have found the actual source of the problem with the original code now though! A fix in the same branch, so just re-download possible-mgpu-fix-2. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=431968 --- Comment #16 from Zamundaaa --- The CPU usage is definitely from the beta - I had such things happen with my git master installation a while ago. You just need to reboot and it will go away, at least until you log in and out again. About the black screen: the log suggests that the driver doesn't accept the buffers for displaying. Are you sure that it worked correctly on the first try? Then I probably just have a bug in the patch somewhere. -- You are receiving this mail because: You are watching all bug changes.

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 #12 from Zamundaaa --- Well, that's good news then! I'll have to ask if the function I used has any caveats (there is effectively 0 documentation about it) but hopefully we can get this in for the release of 5.21 then :) I believe some of those problems may have been because of other problems in your installation / in the beta (as you stated you also had problems without any patches). Could you give me ~/.local/share/sddm/wayland-session.log again (after a reboot), so I can make sure? -- 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 #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 #8 from Zamundaaa --- That reference is for KDE4, I'm not surprised that it doesn't work. You should probably remove env file, it could potentially cause problems. For compiling KWin you can either use kdesrc-build (https://community.kde.org/Get_Involved/development#Set_up_kdesrc-build + add a section in .kdesrc-buildrc to switch to my branch) to compile a whole session to log into (overkill but safe) or install it like this: git clone https://invent.kde.org/zamundaaa/kwin.git -b possible-multi-gpu-fix mkdir build && cd build cmake .. sudo make install -j8 And then after testing reinstall the kwin package to replace the files with stable kwin (or wait for it to update). -- You are receiving this mail because: You are watching all bug changes.

I'll have to look into using modifiers to not require linear buffers if that's the case, although I'm not sure in what timeframe that could be solved. First though, let's see if there are some error messages. For that please run the session with the environment variable "QT_LOGGING_RULES=kwin_drm.debug=true" (for example you can put it in /etc/environment) and attach the file "~/.local/share/sddm/wayland-session.log" afer a reboot -- You are receiving this mail because: You are watching all bug changes.
