[kwin] [Bug 475922] kwin_wayland freeze loop on DisplayLink connection
https://bugs.kde.org/show_bug.cgi?id=475922 --- Comment #20 from Kai Uwe Broulik --- If anyone experiencing this bug could test the above merge request that would be appreciated. I cannot reproduce the issue on my DisplayLink docking station so I’m wary of merging it without having verified it actually fixes the issue (and doesn’t make things worse) -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=475922 --- Comment #16 from Norbert --- To clear up my bad English. 1. With the `KWIN_DRM_NO_AMS=1` Variable, all Displays work correctly and does not freeze or reconnect anymore. This includes using all DP and HDMI ports on the docking station and the in build Laptop HDMI at once. 2. Some times ago(~Plasma6 Beta 2), one frozen Display would freeze the whole session, now only the causing Display is frozen. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=475922 --- Comment #15 from Norbert --- Hi, with `KWIN_DRM_NO_AMS=1` It works now without any issues, I noticed since the latest kwin update even without Variable, kwin does not freeze anymore on the working display outputs. It works even better than with xorg because the input latency is noticeably lower. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=475922 --- Comment #14 from Zamundaaa --- Okay, the drm_info output shows no difference between KWin driving the output when it works vs when it doesn't. Something weird is that drm_info doesn't show the output being driven at all in the X11 session - but that might just be the X11 driver doing weird stuff outside of KMS. As there's no difference between it working and not working from KWin's perspective, I'm confident to say that this is a driver bug, which you can report at https://github.com/DisplayLink/evdi/issues. Maybe we can look at some workarounds though. It looks like KWin us choosing the ABGR format for the output; Xorg is likely using XRGB. If you use `KWIN_DRM_NO_AMS=1` to make KWin do the same, does the issue go away? -- You are receiving this mail because: You are watching all bug changes.

I wanted to say, that there are more outputs visible on the kwin x11 sessions output. Which is weird because kscreen in the Wayland session is able to detect the DisplayLink Monitors. I will attach the kscreen output as well -- You are receiving this mail because: You are watching all bug changes.
