Since two months I have noticed X Server Crashes happening occasionally. After such a crash the login screen is appearing again.
So I have searched through journalctl for the string 'fatal IO error 11'. The latest occasion was:
journalctl --since=2015-08-01 | grep 'Aug 06 01:48'

Has somebody an idea what causes these crashes?

Thank you for your info.
So, if I got it right, there is still no solution for this bug!?

I'm having the same issue. It keeps causing lxdm to close my session, losing the current state of my desktop. Tends to happen when I leave it idol for a bit.

Some of the same errors are happening in this thread. It's being reported as an issue with rebooting, but they appear to be related. In particular, this series of errors seem to be common:
Jan 16 13:46:15 siona org.a11y.atspi.Registry[19935]: XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
Jan 16 13:46:15 siona org.a11y.atspi.Registry[19935]: after 9901 requests (9901 known processed) with 0 events remaining.

org.a11y.atspi.Registry appears to come from the at-spi2-core package. Perhaps we should file a bug with this package?

I am having this issue and the same error messages as well. I have noticed, however, that it seems to depend on which xscreensaver that I select. GLSlideshow will consistently result in an X crash after some time, and kick me back out to a VT. Others (GLMatrix) will not. I am unsure how all of this relates, but maybe another piece to the puzzle.

As I lay out in another forum post, for me this issue ultimately was an Xorg issue that gets solved in the linked post.

Thank you. Although it may still be too early to tell for sure, this seems to be effective for me as well. I have not yet had an issue since switching to UXA.

Any further tips on how to prevent this? I am running Violo's Catalyst (15.12) and Xorg(1.17). Most of the tips refer to intel drivers. This is driving me batty. Twice a week Xorg takes a big crap and restarts.
I can't believe I would actually consider going back to Windows for a stable desktop. Yet I need native docker and others.

For me the same problem occurs. Ubuntu 16.04, using video Sky Lake Integrated Graphics. After the computer lock the session, sometimes occurs, you can not unlock the session. The screen goes black. You must restart the lighdm.
Using the xorg below:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
Option "DRI" "3"
EndSection
