Thank you for your report and work on this. Has anyone else tried updating BIOS as suggested by mason?
Something else to check out is bug #376924, specifically a link to a potential patch at: http://marc.info/?l=linux-acpi&m=124456088526538&w=2. If you are able, try that patch in acpi and report if it helps. To help with debugging can you post the following 3 pieces of information to this bug report: 1) hit the brightness up and down cominations 2) post the output of: cat /var/log/message | grep gnome-power-manager This will return the reason GNOME Power Manager did a specific action. 1) run the command: /usr/sbin/hald --daemon=no --verbose=yes --retain-privileges 2) hit the brightness up and down combinations and post the output of the terminal And finally, could you please attach the resulting log file of: /usr/share/gnome-power-manager/gnome-power-bugreport &> gpm.log to the report? ** Changed in: gnome-power-manager (Ubuntu) Status: New => Incomplete -- Brightness down key doesn't work properly on dell mini (Jaunty Beta) https://bugs.launchpad.net/bugs/355546 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
