This is the Xorg.log.txt file . Please let me know if there's any way I can make it more useful.

Comment 3 Shlomi Fish 2015-11-12 10:47:59 CET 
OK, some news: the crash seems to happen with playing any video file that I tried (.webm, .flv or .mp4) with either mplayer or vlc.  This makes using this system much less usable.

Seems like this upstream commit fixes the problem here if I apply it locally:

http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=e769f9e6ca0b2575f598baf8e2f7dab02a48d6a0

( Thanks to the people on #intel-gfx on Freenode for this insight.)

Hi

Same xorg crash here 

Intel core i5

cauldron up to date

Xorg crash if something needs video hardware acceleration (video with mplayer, Plasma compositing)

Possible workaround : create an /etc/X11/xorg.conf (with XFdrake for exemple) then edit the driver device section and add : Option "AccelMethod"  "uxa"

Section "Device"
    Identifier "device1"
    VendorName "Intel Corporation"
    BoardName "Intel 810 and later"
    Driver "intel"
    Option "AccelMethod"  "uxa" #<--here
    Option "DPMS"
EndSection

It works for me.

I have needed to do the same thing an 15.10 ubuntu up to date (Intel driver too) last week. (but without crash : only pixels glitches in this case

Hint page for me : https://wiki.archlinux.org/index.php/Intel_graphics#SNA_issues
