That shows three monitors connected and active. Was the problem occuring at the time you ran the command?
Please also run this command while the problem is happening so we can see what the compositor thinks the current configuration is: gdctl show > gdctl.txt and attach the resulting text file here. It may also pay to try Nvidia 575 using the Additional Drivers app. ** Summary changed: - Monitor doesn't show any output after boot + [nvidia] One monitor doesn't show any output after boot -- 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/2117418 Title: [nvidia] One monitor doesn't show any output after boot Status in mutter package in Ubuntu: Incomplete Bug description: One of my monitors does not show the screen when Ubuntu boots, like the other monitors do, it just hangs on a black screen like it is not receiving any input. The only workarounds I have found so far are: 1. Unplug and re-plug the monitor 2. Turn the monitor off in the display settings, apply and keep changes, then turn it back on This did not exist on 24.04 or 24.10, but I have reproduced in 25.04 and 25.10. The monitor is an "Acer Nitro 34" 21:9 Curved UWQHD", and it works fine on Windows 11 as well, the problem appears to be exclusive to the newer Ubuntu.
