My screen randomly becomes distorted and freeze in Ubuntu 20.04/22.04. After this only hard reboot works. I have been experiencing this for 2 months now and have tried several solutions but nothing helps. Also I can't find any error log in syslog, kern.log etc.

P.S - This started happening after I upgraded my 4GB+4GB RAM to 8GB+8GB. It also occurs less frequently in Wayland than in Xorg

Configurations

CPU: dual core Intel Core i3-5005U (-MT MCP-) speed/min/max: 1597/500/1900 MHz Kernel: 5.15.0-57-generic x86_64 Up: 31m Mem: 2427.1/15914.1 MiB (15.3%) Storage: 1.14 TiB (1.9% used) Procs: 232 Shell: Bash inxi: 3.3.13

I have already tried following solutions but no help :-

  1. Re seating the RAMS
  2. playing with few grub configurations like i915.enable_psr=0 etc
  3. Disabling browser hardware accleration
  4. Running memory test in the boot menu, everything is fine.

Any help in the right direction would be great.

    Does this answer your question? [How do I diagnose my issue, when I'm not sure if it is a hardware or software issue?](https://askubuntu.com/questions/1384357/how-do-i-diagnose-my-issue-when-im-not-sure-if-it-is-a-hardware-or-software-is) – karel Jan 15 '23 at 01:02
  • I am sure this is not a hardware issue as I already did memtest, but last time I disabled hardware acceleration for chrome I didn't reboot so the issue reoccurred but after again disabling hardware acceleration and reboot, the issue hasn't reappeared for last 2 days – Rohit Kumar Jan 15 '23 at 16:59
