WORKAROUND: Before trying to log in, do this:
1. Ctrl+Alt+F4, log in to VT4 and run: sudo Xorg :4 vt4 2. Ctrl+Alt+F1, wait for the log screen to reappear, then log in normally. No crash. Something about having run Xorg as root already seems to be enough to avoid the bug in the Nvidia driver which is the root cause here. -- 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/1822616 Title: [regression][nvidia] gnome-shell/budgie-wm crashed with SIGABRT "assertion failed: (width > 0 && height > 0 && scale > 0)" in meta_monitor_manager_xrandr_update_screen_size Status in budgie-desktop package in Ubuntu: Invalid Status in gnome-shell package in Ubuntu: Invalid Status in mutter package in Ubuntu: In Progress Status in nvidia-graphics-drivers-410 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-418 package in Ubuntu: Confirmed Bug description: https://errors.ubuntu.com/problem/de2c123796506b10cd9d03070c91b581d7c6ae0c I am unable to use the NVIDIA drivers Ubuntu Budgie installed with 3 vertical displays.
