I'm not saying xorg is the culprit, I think problem is graphics related thus it happens when I choose Nouveau graphics driver instead of proprietary Nvidia.
My GPU is an integrated one and uses shared RAM, this bug is more frequent when hardware settings are "AUTODETECT FRAME BUFFER SIZE=enabled" otherwise when it's set to "FIXED=256MB" it isn't that frequent.
The steps to reproduce this bug are not pretty clear, this crash happens at least once a day, appearently when there's too much memory in use.
I used to use "Nvidia proprietary driver" with Ubuntu 14.10 with less problems but some crashes correctly managed by system without closing any application but with Ubuntu 15.04 this crashes make all applications get closed, that's why I decided to change to Nouveau but it gets so slow. I'm really considering rollback to Ubuntu 14.10 which caused less problems.
When Systems freezes both keyboard and mouse get irresponsive too. I've collected some data through SSH which are attached:
"Xorg.0.freezetime.log" is "/var/log/Xorg.0.log" at Freeze moment.
"kikedmesg.txt" is "dmsg.txt" at Freeze moment.
Please contact me with directions to help in solving this issue.
