Confirming on Acer Aspire 2920 w/ Intel 965GM, Karmic up-to-date. When using Fn-Left or Fn-Right to adjust brightness, the bar on the screen moves, but display does not change. *).
Running "xorg --prop" is missing backlight control. However: m...@acer:/proc/acpi/video/GFX0$ cat DD0[1-5]/brightness <not supported> <not supported> levels: 10 20 30 40 50 60 70 80 90 100 current: 60 <not supported> <not supported> So, DD01, DD02, DD04 and DD05 claim not to support backlight, but DD03 does. *) The brightness DOES change, when trying to reduce brightness when /proc/acpi/video/GFX03/brightness is already at minimum (10), or when trying to increase brightness when the bar it's at maximum (100). Then brightness changes to dim or bright. Is that really minimum and maximum brightness, I really can't tell... -- xrandr backlight property control missing (when using KMS?) https://bugs.launchpad.net/bugs/428054 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
