Problem is still happening after deleting ~/.config/monitors.xml. It seems to work fine without the external monitor.
Now there something related to the nvidia driver power management: - If I chose 'suspend' from the gnome power menu, it sleeps fine. - If I pressed the power button to suspend, it shows nvidia issue as in the attached screenshot. ** Attachment added: "nvidia error" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-575/+bug/2120744/+attachment/5900104/+files/signal-2025-08-19-170105.jpeg -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2120744 Title: Screen turn off while wakingup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2120744/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
