           Summary: Enabling GLX breaks brightness control on radeon
           Product: xorg
           Version: 7.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: francis.kung at utoronto.ca


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.
