Thanks for creating bug 1978764. The freeze does not appear to be one that is visible in stack traces so my next theory is a KMS/DRM screen update failure. To investigate that please try these separately:
* Disable atomic KMS in /etc/environment: MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 and reboot. * Follow the instructions in comment #19 so we can see all the interaction with the kernel DRM functions at the time of the freeze. -- 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/1976204 Title: Screen freeze To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1976204/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
