468823 - Unittests should be run with DISPLAY=:2 on linux

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P2)

Description

[Chris AtLee [:catlee]]

Attachment: set DISPLAY=:2 in env.py

Unittests often fail on linux if buildbot isn't started with DISPLAY=:2

The attached patch puts this in the environment so that buildbot can be started via ssh.

Bonus points: make sure Xvfb and metacity are running

Why didn't we do this sooner? :)

Well, that didn't work at all :P

The following crontab entries seem to do the trick:
# Make sure Xvfb is running on :2
*/5 * * * *	ps -C Xvfb | grep -q Xvfb || exec Xvfb :2 -screen 0 1280x1024x24 &

# Make sure metacity is running on :2
*/5 * * * *	ps -C metacity -f | grep -q :2 || exec metacity --display :2 --replace &
