There are a few issues there: * Permission denied happens more often with cursor-only updates than primary plane updates. And seemingly mostly happens to the login screen's gnome-shell instance (which is correct if it has since started the user session). If permission denied on cursor updates is somehow causing this bug then you might be able to work around it by adding MUTTER_DEBUG_FORCE_KMS_MODE=simple to /etc/environment and rebooting.
* The VT is changing from 2 to 6 in each log. Are you using Ctrl+Alt+F6 to manually recover? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2089709 Title: Ubuntu 24.04 sometimes logs in to a black screen if the mouse is moved during login Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: I recently upgraded from Ubuntu 22.04 to Ubuntu 24.04. Now whenever I log in, sometimes I'll get a blank screen. It will only show the mouse cursor as an X. The problem seems to be intermittent. So far it's only happened to me using X11. My current workaround: 1. Open another terminal (e.g. Ctrl+Alt+F6) 2. Restart gdm3 (sudo systemctl restart gdm3) This seems to be affecting many people, although I couldn't find an existing bug: https://askubuntu.com/questions/1514757/issue-with- ubuntu-24-04-black-screen-with-cursor-on-login $ lsb_release -rd No LSB modules are available.
