xorg log
X session crashes after some use, several times a day under normal desktop
usage.
I'll attach xorg log
I've noticed one more strange thing that is possibly related. Output of this
command:
cat /proc/{xorg pid}/maps | grep mm | wc -l
(this looks for lines like this: 7fd313cc8000-7fd313d09000 rw-s 00000000 00:05
41728 /drm mm object (deleted))
goes to 10's of thousands. It seems to be growing quicker if some videa
application is being used (google hangouts). Stopping browser (and hangouts)
doesn't seem to release those mmaps.
The frequency of the crashing seems to be roughly correlated to time of hangout
usage and therefore it looks like crashes and number of mmaps growing without
bounds seems related.
This all happens with current iobaf build on Ubuntu Trusty (Mint). Rolling back
to vivid lts packages seems to be keeping number of mmaped regions to less than
150 and no crashes so far.</pre>
