Linux mint 22 flashing screen on laptop with intel graphics
by Gillsman1 from LinuxQuestions.org on (#6Q97G)
This information is for anyone using a laptop with Intel UHD520/620 i915 graphics running Linux mint 22
If like me your screen sometimes flashes or you see horizontal lines on screen, the fix is as follows.
Open the terminal.
Open the grub configuration file by typing sudo nano /etc/default/grub.
Find the line that starts with GRUB_CMDLINE_LINUX_DEFAULT.
Change it to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dc=0 intel_idle.max_cstate=2".
Press Ctrl+X to exit, then Y to save changes.
Finally, update grub with sudo update-grub.
After trying many suggestions including using different kernels and a few tears (only joking) this finally worked for me & I hope it helps if anyone else is having the same issue.
