href="show_bug.cgi?id=28739">bug 28739</a>. It has also been reported at:
<a href="https://bugs.archlinux.org/task/32636">https://bugs.archlinux.org/task/32636</a>
Description:
On my Lenovo ThinkPad W500 running Arch Linux, waking the display from display
sleep causes the machine to lock up. In particular, either the screen goes
black and does not respond to any key combination (although the network light
keeps blinking) or the screen shows one frame of the screensaver with the
unlock dialog, but the dialog does not respond to input. The only recourse is
to do a hardware restart (using cntrl+alt+delete has no effect, and using
CTRL+ALT+F# has no effect). On restart, the brightness in X is set to its
lowest setting.
This problem started when upgrading from 2.20.9-2 to 2.20.12-1. Downgrading
back to 2.20.9-2 fixes the problem. The problem is consistently reproducible on
this laptop. It has not been tested whether versions between 2.20.9-2 and
2.20.12-1 also have the problem.
Additional info:
* xorg-video-intel 2.20.12-1 (or higher)
Steps to reproduce:
1. Let screen saver start
2. Let screen go to sleep
3. Attempt to wake the display from display sleep</pre>
