Public bug reported: I can confirm this problem: https://askubuntu.com/questions/1306700 /fixing-gpu-hang-caused-by-i915-driver
Symptom: unable to launch any application after login on to the system, login screen etc works fine. The system thus becomes completely unusable for regular users. I have tried both X and Wayland. Workaround: boot using "nomodeset" kernel parameter. The lowlatency kernel did not help in my case.
