screen blinking with i915... stuck for months... about to throw away my laptop
I'm using Ubuntu 14.04 LTS 64bit on my new Laptop.
The problem is that screen keeps blinking like rainbow.(blinks both in X and console)
This is what happened on my laptop http://www.youtube.com/watch?v=mOY4RDhi8sY
My workaround was editing /etc/default/grub.
But that wasn't a perfect solution, because I can't adjust screen brightness and laptop becomes so slow when I play graphical games after that.
So I want to know if there is a better solution.
I told you, it's sound on video. I can even hear the sound on that recording. Get the sound quiet and see if that changes things. Also post your driver details. Video these days relies on mesa, the kernel driver, xorg server, libdrm, libpixman, and perhaps a few other things.Correct versions are important. And get the sound to shut up. It sounds like you are out in the wind somewhere recording that.
BTW I tried with other kernel parameters such as
i915.reset=false , i915.enable_hangcheck=false
And they had same effects with i915.modeset=0
Screen blinking disappeared but screen brightness adjusting was disabled and gaming graphics became so slow(I guess hardware video acceleration was disabled)
Distribution: Debian Wheezy, Jessie, Sid/Experimental, playing with LFS.
If the problem is what I think it is, I only just saw the video so it may be different, you have to try various settings each one has a different effect. Some people use nomodeset, others use i915.modeset=1, while others use i915.modeset=0
If the issue isn't what I think it is are you using the correct firmware?
