I think I am getting closer to the issue. Yesterday I did a clean reinstall of 20.10 because I thought something in the update process from 20.04 to 20.10 had broken. However, even with a fresh 20.10 this issue persists.
I have the feeling that it may be related to Wayland and HiDPI scaling: As I am using an external screen I wanted to enable 125% scaling of Wayland right after my fresh installation. For that I need to enable the "experimental features": gsettings set org.gnome.mutter experimental-features "['scale-monitor- framebuffer']" Right after typing that command in the console GDM crashed. As requested by Maciej I attached my journalctl output. As you can see it is full of errors related to the icons. Next I will try do disable the experimental features and see if the problem persists - although this makes my external screen hardly usable (200% is way too large, 100% to small). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902918 Title: GDM crashes after upgrade to 20.10 due to apparmor and snap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1902918/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
