Xorg crash

[dwilches]

Each time I turn my screen off I get logged out of my session. I have to log in again and all my apps have been forcefully closed (Chrome mentions it didn't close cleanly and offers me to restore my tabs, for example).

This happens after 5 minutes of inactivity (I have the setting for screen off at 5 minutes) and also when I turn off my screen by myself.

Some more info:

To diagnose this problem we still need a crash file. Please:

1. Apply the workaround from bug 994921.
2. Reboot and reproduce the crash.
3. Look in /var/crash for new crash files.
4. Run: ubuntu-bug /var/crash/YOURFILE.crash
5. Add a comment in this bug telling is the ID of the newly-created bug.

Tried two workarounds mentioned in that bug, none worked (the crash did not generate any files in /var/crash).

The first workaround I tried was:

    comment out line 23 ("'problem_types': ['Bug', 'Package'],") in '/etc/apport/crashdb.conf'.

I put an # at the beginning of line 20, not 23 because line 20 is the one that mentions problem_types, but after a restart and reproducing the crash I didn't get any new crash files in that folder.

Also tried adding `Crash` to the list of problem_types (as mentioned in https://bugs.launchpad.net/ubuntu/+source/apport/+bug/993450/comments/13 ) but same thing, no new files after a restart and a crash.

Something else I can try to generate the crash file?

[dwilches (dwilches)]

Found the issue when looking at `/var/log/apport.log`. This may be useful for other people to whom you ask to do that workaround:

RROR: apport (pid 2496) Tue Mar 6 21:33:37 2018: apport: report /var/crash/_usr_bin_gnome-shell.1000.crash already exists and unseen, doing nothing to avoid disk usage DoS

So I removed the crashes I already had in /var/crash. Will reproduce the crash now and report back in a moment.

@vanvugt I followed your instructions and created the bug https://bugs.launchpad.net/bugs/1753912 with the crash file

[Daniel van Vugt (vanvugt)]

Great, thanks. But I can't access that bug so it must be private. Unusual though, since as a member of ~ubuntu-bugcontrol I should be able to see it...

Please wait until that bug has finished retracing, then remove any sensitive personal information attachments from it, then change it from Private to Public (top right of the page).

[dwilches (dwilches)]

Went to the other bug and saw it is already public now.

[Daniel van Vugt (vanvugt)]

Great, thanks. This is now a duplicate of bug 1724439.
