I’ve just stumbled upon a reliable way to crash Xorg while attempting to launch multiple LXC containers. It’s as simple as:
for i in {1..4}; do lxc launch ubuntu:f c${i} --profile k8s; done
Within a few seconds (or minutes if the image wasn’t fresh) of running that command, Xorg will crash and I’ll have to log in again and of course, all previously opened apps will have been closed unceremoniously and then several crash reports popup and I obediently them off somewhere via whoopsie. I’ve repeated this process 3 times with 100% repeatability on the Lenovo and 33% on the Dell - both are on Ubuntu 22.04. It actually might be 100% on the Dell, but I forgot to attach the k8s profile
on the first 2 tries.
So, it appears like the k8s profile I’m using might not be correct for Ubuntu 22.04???
Let me know what you’d like me to provide to help troubleshoot this issue.
I’m not using Wayland as it causes glitching towards the lower 3rd of the monitor whereby the mouse pointer jumps all over the place.
