[Solved] No video in VLC after kernel update to linux-lts 4.1.8-1

After an update on 2015-09-25 I noticed graphics problems. At login (with LXDM) the login screen did not fully appear (some elements were missing). And as I tried to watch a video file in VLC only the sound could be heard but no video could be seen.

To analyse the problem I tried to paly video files on a laptop also having Archlinux installed. But in this case the installation was not updated. And the video could be played with no problems at all. So I did a comparison of the versions of the installed software packages on the two machines.

A try with a downgrade of linux-lts (4.1.8-1 -> 3.14.52-1) solved the problem and video files are played as they should.

So it seems that linux-lts 4.1.8-1 caused the problems.
Has somebody an idea whats wrong with that?

What graphics driver you use?

While searching around for similar problems, I have noticed that other threads are concerned with GPU HANG issues.
Gusar mentions “that the 4.1 and 4.2 kernels are quite bad for intel graphics” here: https://bbs.archlinux.org/viewtopic.php … 8#p1566278

So I inspected my journalctl for it too and have found

when I used Kernel: 4.1.6-1-ARCH.

At the moment I can't see no other solution than avoiding an update of the kernel to a higher version than linux-lts 3.14.52-1.

Changing from SNA to UXA with my Intel graphics solved the problem for me!
