Flashing screen on Linux mint 22 with Intel UHD620 graphics

[gillsman]

I have posted before on this issue and I thought I had solved it by upgrading the kernel from 6.8 to 6.9 however yesterday it started happening again so I searched around yet again for answers, this time I found a few people reporting this same problem & the general consensus seems to be Mint 22 has an issue with Intel graphics, specifically UHD620 & UHD520

I found this suggestion ~
Edit GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to read
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dc=0 intel_idle.max_cstate=2"

Then run sudo update-grub
and reboot.
I have done this and so far the problem has not surfaced although I thought I had solved it before and it returned, still, I'm monitoring the situation and hoping this time it works.

For clarity I should have said in 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 read
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dc=0 intel_idle.max_cstate=2"

Be sure to update grub after making that change.

sudo update-grub
