On a Thinkpad R61 this bug happens exactly as reported in the bug description (the "what works" and "what doesn't work" are the same).
However removing the script /usr/lib/hal/scripts/hal-system-lcd-get-brightness does not seem to help. After the script is removed pressing the Fn+keys to raise and lower the brightness while in the gnome session has no effect on actual brightness. Also removing this script prevents the brightness to be changed even when moving to a console with CTRL+ALT+n, which works if the script is present. Finally the solution reported in the comment by Mingming to write to /sys/class/backlight/acpi_video0/brightness doesn't have any effect on brightness and neither /sys/class/backlight/acpi_video0/brightness nor /sys/class/backlight/acpi_video0/brightness report the actual brightness value. -- brightness indicator does not work on thinkpad https://bugs.launchpad.net/bugs/137972 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
