Bug#780990: xserver-xorg-video-intel: hangs startx on logout if xrandr rotate is used in session

[Chris Bainbridge <chris.bainbridge@gmail.com>]

Package: xserver-xorg-video-intel
Version: 2:2.21.15-2+b2
Severity: important

Dear Maintainer,

startx hangs on logout if xrandr rotate is used in session. There may
be other ways to hang it but xrandr rotate is reliably repeatable.

To reproduce:

1. Install minimal Jessie netinst system
2. apt-get install xorg blackbox # (bug does not seem to happen with gnome)
3. log in
4. startx
5. xrandr --output eDP1 --rotate left
6. right-click screen -> exit
7. terminal is hung. Nothing responds - can not change terminal,
ctrl-c, or anything.

Installing the latest upstream git appears to fix this bug.
