Thanks for the bug report. I can see two possible problems here that might relate to screen flicker:
* The i915 kernel driver crashed, in intel_modeset_init * Xorg is using probably the wrong driver 'intel'. It should be using the modesetting driver on a modern system like yours. Please try removing that wrong driver: sudo apt remove xserver-xorg-video-intel or just try logging into "Ubuntu on Wayland" instead. Maybe it's some combination of the above two issues. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Also affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862459 Title: ubuntu 18 screen flicker/blink To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1862459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
