There are some fixes going in to the next Ubuntu 6.8 kernel coming out,
but I was wondering if you could test booting with the option
"i915.enable_psr2_sel_fetch=0" on the kernel command line.
You can either add this in grub when you reboot the machine, or by
adding it to the kernel command line in the grub config file, and
updating grub.
If you need info on any of this, please let me know.

Title:
(i915) external monitor flickering in 6.8.0-40.40~22.04.3
Status in linux-hwe-6.8 package in Ubuntu:
Confirmed
Bug description:
I used sudo apt-get upgrade in Ubuntu 22.04.4 .
Then karnel upgraded from 6.5.0-45.45~22.04.1 to 6.8.0-40.40~22.04.3.
Now I am facing problem to my external monitor(1920x1080), that was blinking.
Setting low resolution(ex:1680x1050) from settings for this monitor, blinking
has gone.
Another soluton That cause huze performance:- Changing karnel
6.5.0-45.45~22.04.1 to 6.8.0-40.40~22.04.3 at the time of booting.
I tried Ubuntu 24.04, But it has the same blinking problem.
