X11 breaks my Multi Monitor Setup

#1 Post by marcel58095 »

Hey,
I got a problem with my X11 Configuration.
X11 does break my settings "randomly" and my monitors look like on the pictures below.If I change my settings in nvidia-settings (with root previleges) and save it to /etc/X11/xorg.conf it will work again. If I restart my PC it does work fine. But if i turn of my PC and turn it on it is broken again. Not sure why there is a difference at all.

On the pictures below you can see how it is supposed to look and how it looks if the problem appears.
Also I have to restart in recoverymode when this problem occurs to delete the xorg.conf file, because the mouse pointer is shown on the wrong position while I have this problem.
Not sure if it is related to this problem but if I click on an icon on the taskbar right, the menu opens to far on the left like shown on the picture.
If you got any questions just ask!

It would be useful to collect and compare X server logs before and after the issue occurs. These logs are usually in /var/log/ or in /.local/share/xorg/ .

Do you mean after suspension to ram or suspension to disk ?

I haven't seen something suspicious in the logs. But I will have a look again later.

And no, if I restart the PC (with sudo reboot), what should be the same like turning it off and on again everything works just fine. But if I shut down the pc (with sudo shutdown) and turn it on again it's broken again.

I just read something that this could be a bug in KDE Plasma 5.25.

Should be fixed in 5.27.
Hopefully it will realease quickly in Debian Testing.

Very unusual.

Yeah, that's really weird.
On KDE 5.20 I haven't had this problem.

The reference is the following:

Its not exactly my problem but my problem is similar.
