Hello,
two days ago I had to kill X because it was completley stuck and since than (I think it was since than) all videos are really slow. It doesn't matter if it is in firefox, chromium or just vlc. I just remembered I emerged playonlinux the day before .... Any ideas?

Thats wired I just noticed that the sound also doesn't work but when I went into the sound settings and changed the input(!!!) device level the sound came back. Now the video also does work again? What can that be? I updated everthing (world)!

chi86,

Do you really have separtate Intel and nVidia graphics systems or is it an Optimus graphic system?

Your current Xorg.0.log shows you are using the Intel graphics only.

chi86,

Not yet. Not until I know if you have Optimus or not.

Optimus is only one and a half graphics systems. The nVidia half has no connection to the display surface, so trying to use it alone always provides disappointing results.

Optimus has its own setup. The Intel chip always reads the pixel buffer to the display but you can switch between Intel and nVidia for drawing into the pixel buffer.

chi86,

OK, go for it. If you do have Optimus and don't know it, trying to use nVidia only will get you a blank screen.
We will be able to tell from your new Xorg.0.log if you have Optimus and you tried to use tho nVidia part on its own.

I found this manual (https://wiki.gentoo.org/wiki/NVIDIA_Driver_with_Optimus_Laptops) and I will try it this week because it looks a bit difficult ....
