** Description changed:
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.
