--- Begin Message ---Package: xbacklight Severity: normal xbacklight -set sometimes has no effect. For example, when I suspend and resume my laptop, the backlight is reset to 100%, but is still reported as whatever I set it to before. xbacklight seems to do nothing if I try to set it to the same value; instead, I must first set it to a different value. -- System Information: Debian Release: 5.0 APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.26-1-686 (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages xbacklight depends on: ii libc6 2.7-16 GNU C Library: Shared libraries ii libx11-6 2:1.1.5-2 X11 client-side library ii libxrandr2 2:1.2.3-1 X11 RandR extension library ii libxrender1 1:0.9.4-2 X Rendering Extension client libra xbacklight recommends no packages. xbacklight suggests no packages.

If this is still an issue please open a bug against the video driver with the output of "xrandr --verbose" before and after suspend, and output of "grep -r . /sys/class/backlight/*/" (and your X log).
