Same problem here on my R61. Brightness stopped working after a Hardy upgrade a few days ago.
Also, when I press the brightness keys there is a 3 second delay before the indicator pops up - the level bar goes up and down but the brightness does not change. Whenever I press the brightness keys I get the following in the ring buffer: [ 707.516717] thinkpad_acpi: unknown LID-related HKEY event: 0x5010 [ 710.394765] thinkpad_acpi: unknown LID-related HKEY event: 0x5010 [ 710.508695] thinkpad_acpi: unknown LID-related HKEY event: 0x5010 -- Backlight adjustment no longer works on Thinkpad X61s https://bugs.launchpad.net/bugs/197929 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
