I don't know if the following is related but I made settings according to: https://bugs.launchpad.net/gnome-shell/+bug/1968040
I added this option: MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 to /etc/environment Now both screens don't turn off - the internal screen and the external screen. The screens just get blank. -- 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/1973467 Title: [Ubuntu 22.04] [nvidia] [Wayland] Screen Blank: External screen is not turned off in sleep mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1973467/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
