Additionally, any further discussion regarding the bug should occur in the other report. Please continue to report any other bugs you may find.

[Stephan Springer (geryon)]

Duplicate of a private bug? This does not make sense to me. → Removed

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Alberto Salvia Novella (es20490446e)]

Does this bug render the system temporally unusable?

When answered, please set this bug status back to "confirmed". Thank you.

> Does this bug render the system temporally unusable?

Yes. I have to wait 2 to 30 seconds before i can login again. All programs are closed (Rhythmbox plays till 1 second before the Login Screen appears).

> Does this bug render the system temporally unusable?

see https://launchpadlibrarian.net/221306726/20151015_065628.jpg from https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1506384 for after click on button in Thunderbird and before login is possible. It happens happens too sometimes in LibreOffice and Firefox.

[Stephan Springer (geryon)]

Yes, the system is definitely unusable. The screen is black for about 30 seconds, and then the login screen appears.

Obviously, all running programs have been stopped, which means a potential data loss.

Today it happened two times in a row, both times when Shift-clicking on the “Reply” button at an e-mail in Thunderbird.

In the last three weeks while on Wily I've had this crash five or six times.

[Nikolas Hermann (nikolas-hermann)]

This ssems to be a duplicate of https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1510970 (see XorgLogOld.txt).

If so, disabling sna should be a workaround for now:

sudo bash -c 'cat <<EOF > /usr/share/X11/xorg.conf.d/20-intel.conf
Section "Device"
 Identifier "Card0"
 Driver "Intel"
 Option "AccelMethod" "uxa"
EndSection
EOF'

Reboot afterwards.

[Stephan Springer (geryon)]

Thank you, disabling SNA worked – no more crashes in the last three weeks.
