Hello,
Xorg tends to crash at least once per hour while I'm working, so I spent
some time tracking down the issue again.
Crashes began after the last apt-get upgrade, and I remember that
xserver-xorg-video-intel was in the list of the upgraded packages, so I
decided to try to revert it, but due to the missing xorg-video-abi-18
dependancy I was unable to do it normally, so I unpacked the archive,
backed-up the original intel driver and replaced it by the one in the
package manually. No more crashes since then.
The working intel driver is in the 2:2.99.917-2~bpo8+1 version from the
jessie-backports.
Something is wrong with the current version 2:2.99.917+git20160127-1+b1
ps: I'm unable to edit the bug report, so probably it should be edited
by administrator as the bug seems to be in the xserver-xorg-video-intel
package, not in the reported one.
Regards,
Stanimir
