[gm45] Adjusting Brightness in Acer Aspire Timelines causes system
freeze
Experiencing this issue with Natty 11.04 on a 5810T.
I erroneously created another bug report for this issue at this URL
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/783262
Here's the description as my comment here. Feel free to remove the other
bug, if this is the proper place.
When I examined the function key press using logkeys
(http://code.google.com/p/logkeys/)
I noticed that a single key press of the Function key alone registers two times.
E-1d0E-1d0
The documentation for the logkeys logfile format, indicates that 1d0 is
the keycode in hexadecimal format.
The bug is still present on my 5810TZ.

Here is a workaround to set the Brightness via shell:

be careful with low values, 00 is completely black.

@TexLogic: since this bug is still unassigned, most probably not!
The problem however seems to be located in the intel video driver, and Intel
developers are suggesting to report such problems at bugs.freedesktop.org,
doing so might make it more visible to the right people.
