1. When the problem is happening, does the kernel log show any problems? (run: dmesg) When the problem is happening, the screen is black, so no easy to type command. I can try ssh before reproducing, but might not soon, I need to handover this machine to another guy today.
Before that, can you get message you need in syslog? or I can upload kern.log for your reference. 2. When the problem is happening, what do you get from running these commands? ls -l /proc/`pidof Xorg`/fd | wc -l ls -l /proc/`pidof Xorg`/fd When the problem is happening, the screen is black, so no easy to type command. I can try ssh before reproducing, but might not soon, I need to handover this machine to another guy today. Is there other way to get information you need in next boot? So that I can provide more on current environment that next boot of issue happened. 3. When the problem is happening, what do you get from: ps auxw | grep Xorg Same response as 2. 4. Please try the same test with "Ubuntu on Wayland" and tell us if it has the same bug. This would be my lower priory, the target of my testing is to make sure end user's experience on LTS.
