           Summary: Cannot alter brightness as normal user
           Product: xorg
           Version: 7.4
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: r.spliet at student.tudelft.nl
         QAContact: xorg-team at lists.x.org


As a normal user using nouveau I cannot alter the screen brightness of my
laptop. Not using the function keys, not echo'ing the desired value to
/proc/acpi/video/VGA1/LCDD/brightness. I can however become root with su, and
then echo the desired value to this procfs node.

ls -alz shows:
-rw-r--r--. root root system_u:object_r:proc_t:s0      brightness

When I use Intel graphics on the exact same hardware (hybrid graphics - BIOS
option), I can use the function keys for altering brightness.

Hardware: Asus UL50Vg with hybrid graphics (Intel intergrated/Geforce G210M).
OS: Fedora 12, all updates installed.
