Reverting to mirror mode suggests the system doesn't recognise the new config on wakeup as being equal to the old config before sleeping.
One of your configurations in ~/.config/monitors.xml seems to contain a disabled "unknown" monitor which likely was bug 2060268. So I suggest: 1. Make sure you have the fix for bug 2060268 installed (ubuntu-drivers- common >= 1:0.9.7.6ubuntu3.1) 2. Delete ~/.config/monitors.xml 3. Log in again and reconfigure your monitors. Does the problem still occur after that? If so then it could also be caused by a sub-par display cable reporting lower bandwidth upon waking from sleep (a common problem). This might make the system treat it as a new monitor and it won't remember the old layout. The fix for that is usually to use higher grade display cables. ** Package changed: xorg (Ubuntu) => mutter (Ubuntu) ** Changed in: mutter (Ubuntu) Status: New => Incomplete ** Summary changed: - Problems when my computer monitors go to sleep + Multimonitor layout is forgotten after waking from sleep -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2080782 Title: Multimonitor layout is forgotten after waking from sleep Status in mutter package in Ubuntu: Incomplete Bug description: Ubuntu 24.04.1 LTS Xorg 1:7.7+23ubuntu3 500 My default position for my two monitors is having the 34 inch ultrawide and on top of the 16:9 25 inch. This works well after boot up or if I restart with alt f2 and r. How4ever, after 'sleeping' when the monitors wake up the layout has changed with the content of the 25 incher duplicated, appearing both on itself and aligned left on top of the content of the ultrawide. If I use display settings to reposition the monitor with the ultrawide to the left of the 25 incher, things work as expected, with each monitor showing only their content, but when I try to move the ultrawide on top, the duplication/overlap effect happens again. I have tried several different nvidia drivers, this has not helped.
