When you are returned to the login screen, does Ctrl+Alt+F2 fix it? If not then:
Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps: 1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Package changed: xorg (Ubuntu) => mutter (Ubuntu) ** Changed in: mutter (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1970107 Title: [nouveau] Xorg crash / Graphics Issue Status in mutter package in Ubuntu: Incomplete Bug description: I am using a wayland display manager, an internal graphics / Dedicated Graphics laptop where the HDMI is controlled by the dedicated graphics. Currently, with proprietary drivers on ubuntu 22.04 When I connect a display to the hdmi it only shows a white screen, when I try to change the projection to mirror, or external only, it crashes and goes back onto the logon screen. I currently cannot cast at all to a monitor. The monitor I am trying to connect is a 4k and my laptop screen is 1080p if that makes a difference. I am sure I am not the only one who uses this feature, but because I have a mixture of internal and dedicated control, it may have more an issue.
