Description Francis Kung 2007-01-17 11:48:47 UTC 
The Fn-F9/Fn-F10 brightness control keys on a HP nc6000 laptop stop working when
the glx module is loaded - commenting out this module and restarting the machine
results in brightness working (but, of course, no glx).

The video card is a rv350 (Radeon 9600 M10), using the radeon driver. 
Brightness works with glx when using the fglrx driver.

An interesting note to add - if I start up the computer with glx (and no
brightness control), and then comment out the glx module and restart the X
server (ctrl-alt-backspace), this still will not result in working brightness
control: I need to restart the computer in order to get brightness control back.

FWIW, I'm running Fedora Core 6, with all updates.  Let me know if you need any
other information.

Seems to be fixed in the latest update...
