Re: Video problems on Acer after Kernel Update

Have you searched the forum for screen flickering issues? Seems like there were some threads on it recently.

Re: Video problems on Acer after Kernel Update

I'm not even sure what I'm seeing on your "screenshot". What are these white patches? Backlight bleeding?

So appearently linux falls by to text mode. What do kernel- and Xorg-log say?

I also have no idea what it could be and also don't know how to describe it.
I downgraded the kernel and those flickers were gone
