Public bug reported: Kubuntu 8.04 with current updates 2008-06-04:
Although the brightness keys <Fn><Pos1>,<Fn><End> work fine, brightness settings are not remembered on Lenovo Thinkpad T61. I tried it with kde- guidance-powermanager and with kpowersave none of them remember the brightness settings when locking the screen and returning back to desktop session. Steps to reproduce: 1. Change brightness in kde-guidance-powermanager applet for example to 40% 2. Everything will be fine 3. Lock your screen > Main menu > Lock session 4. Screen goes black 5. Move your mouse and type in your password and the screen will go back to 100% brightness Output of /var/log/acpi: Brightness keys just work fine, but after unlocking session, there is no entry in log file that brightness jumped up to 100% again: [Wed Jun 4 10:12:16 2008] received event "video LCD0 00000086 00000000" [Wed Jun 4 10:12:16 2008] notifying client 5859[109:119] [Wed Jun 4 10:12:16 2008] notifying client 28287[0:0] [Wed Jun 4 10:12:16 2008] notifying client 32317[0:0] [Wed Jun 4 10:12:16 2008] client has disconnected [Wed Jun 4 10:12:16 2008] executing action "/etc/acpi/video_brightnessup.sh" [Wed Jun 4 10:12:16 2008] BEGIN HANDLER MESSAGES [Wed Jun 4 10:12:16 2008] END HANDLER MESSAGES [Wed Jun 4 10:12:16 2008] action exited with status 0 [Wed Jun 4 10:12:16 2008] completed event "video LCD0 00000086 00000000" [Wed Jun 4 10:12:22 2008] received event "ibm/hotkey HKEY 00000080 00001011" [Wed Jun 4 10:12:22 2008] notifying client 5859[109:119] [Wed Jun 4 10:12:22 2008] notifying client 28287[0:0] [Wed Jun 4 10:12:22 2008] executing action "/etc/acpi/thinkpad-brightness-down.sh" [Wed Jun 4 10:12:22 2008] BEGIN HANDLER MESSAGES [Wed Jun 4 10:12:22 2008] END HANDLER MESSAGES [Wed Jun 4 10:12:22 2008] action exited with status 0 [Wed Jun 4 10:12:22 2008] completed event "ibm/hotkey HKEY 00000080 00001011" [Wed Jun 4 10:12:22 2008] received event "video LCD0 00000087 00000000" [Wed Jun 4 10:12:22 2008] notifying client 5859[109:119] [Wed Jun 4 10:12:22 2008] notifying client 28287[0:0] [Wed Jun 4 10:12:22 2008] executing action "/etc/acpi/video_brightnessdown.sh" [Wed Jun 4 10:12:22 2008] BEGIN HANDLER MESSAGES [Wed Jun 4 10:12:22 2008] END HANDLER MESSAGES [Wed Jun 4 10:12:22 2008] action exited with status 0 [Wed Jun 4 10:12:22 2008] completed event "video LCD0 00000087 00000000" If you need more info just let me know ** Affects: kde-guidance (Ubuntu) Importance: Undecided Status: New -- Brightness settings not remembered on T61 https://bugs.launchpad.net/bugs/237291 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
