I can confirm that on my Lenovo/IBM Thinkpad X61s laptop the brightness buttons don't work either. Worse still, however, the brightness doesn't seem to change *at all* - for example when going from AC to battery.
Pressing the "brightness up" key produces the following log: [Fri Mar 7 21:15:24 2008] received event "ibm/hotkey HKEY 00000080 00001010" [Fri Mar 7 21:15:24 2008] notifying client 5683[110:122] [Fri Mar 7 21:15:24 2008] notifying client 5830[0:0] [Fri Mar 7 21:15:24 2008] executing action "/etc/acpi/thinkpad-brightness-up.sh" [Fri Mar 7 21:15:24 2008] BEGIN HANDLER MESSAGES [Fri Mar 7 21:15:24 2008] END HANDLER MESSAGES [Fri Mar 7 21:15:24 2008] action exited with status 0 [Fri Mar 7 21:15:24 2008] completed event "ibm/hotkey HKEY 00000080 00001010" [Fri Mar 7 21:15:24 2008] received event "video LCD0 00000086 00000000" [Fri Mar 7 21:15:24 2008] notifying client 5683[110:122] [Fri Mar 7 21:15:24 2008] notifying client 5830[0:0] [Fri Mar 7 21:15:24 2008] executing action "/etc/acpi/video_brightnessup.sh" [Fri Mar 7 21:15:24 2008] BEGIN HANDLER MESSAGES [Fri Mar 7 21:15:24 2008] END HANDLER MESSAGES [Fri Mar 7 21:15:24 2008] action exited with status 0 [Fri Mar 7 21:15:24 2008] completed event "video LCD0 00000086 00000000" and similarly down: [Fri Mar 7 21:16:58 2008] received event "ibm/hotkey HKEY 00000080 00001011" [Fri Mar 7 21:16:58 2008] notifying client 5683[110:122] [Fri Mar 7 21:16:58 2008] notifying client 5830[0:0] [Fri Mar 7 21:16:58 2008] executing action "/etc/acpi/thinkpad-brightness-down.sh" [Fri Mar 7 21:16:58 2008] BEGIN HANDLER MESSAGES [Fri Mar 7 21:16:58 2008] END HANDLER MESSAGES [Fri Mar 7 21:16:58 2008] action exited with status 0 [Fri Mar 7 21:16:58 2008] completed event "ibm/hotkey HKEY 00000080 00001011" [Fri Mar 7 21:16:58 2008] received event "video LCD0 00000087 00000000" [Fri Mar 7 21:16:58 2008] notifying client 5683[110:122] [Fri Mar 7 21:16:58 2008] notifying client 5830[0:0] [Fri Mar 7 21:16:58 2008] executing action "/etc/acpi/video_brightnessdown.sh" [Fri Mar 7 21:16:58 2008] BEGIN HANDLER MESSAGES [Fri Mar 7 21:16:58 2008] END HANDLER MESSAGES [Fri Mar 7 21:16:58 2008] action exited with status 0 [Fri Mar 7 21:16:58 2008] completed event "video LCD0 00000087 00000000" For what it's worth, % sudo dmidecode --string system-manufacturer LENOVO This is Hardy, updated as of 7th March 2008 using acpi-support 0.105. IMHO this is a very important bug to fix given the power drain caused by high-brightness LCD. I'm quite sure it *used* to work, at least in Gutsy, though IIRC it was a bit unpredictable. -- Why isn't thinkpad-brightness-down.sh used for Lenovo thinkpads? https://bugs.launchpad.net/bugs/161745 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
