Created attachment 140381 [details] dump of kwin crash SUMMARY The moment I plug in a second monitor (HDMI) Kwin crashes and my session ceases. If the monitor is plugged in when logging in through SDDM, the session crashes immediately and I get thrown back to the log-in screen. The only way to use my computer currently is to not use a second monitor. This started to happen after a rather big system upgrade, which updated Kwin from 5.22.2.1 to 5.22.3 and the KDE-Frameworks from 5.83.0 to 5.84.0. Update to Kwin 5.22.4 didn't fix the issue. Unfortunately the issue could be related to another component too. At the same time, I also updated the kernel from 5.12.14 to 5.13.4, but after a downgrade the issue remained. POSSIBLY RELATED During lots of restarts, once the configuration worked when KDE forgot the display configuration and the displays where aligned horizontally. The moment I changed it back to vertically inside system settings, it crashed and I wasn't able to try it out again. How do I delete the (two-) monitor configuration manually? Also, the system is a notebook with Intel + Nvidia graphic cards, Kwin should run on the Intel card, but afaik the HDMI interface uses the Nvidia card somehow. Also, inside the log there where issues with Thunderbolt. I don't know if Thunderbolt and HDMI are related. I removed ›bolt‹ for now, but it didn't change anything. FURTHER Please let me know how I can obtain more useful information for you. I guess it's hard to do anything right now.
