I can confirm that this bug is still present in Karmic (I'm on a Dell D820). With the "reduce backlight" option enabled and the "dim backlight when idle" disabled, the backlight is automatically reduced to 50% when unplugging AC. When I then up the backlight to 100% and let the system sit idle for a while, the backlight is reduced to 50% again. The idle time seems to be random, sometimes it happens after 5 seconds, sometimes after 50 seconds. The maximum idle time is around a minute or so.
This issue seems more or less similar to what "drekbour" describes in this bug-report: https://bugs.launchpad.net/ubuntu/+source/gnome-power- manager/+bug/292840/comments/3 I can reproduce this bug. The only workaround I found so far is to disable the "reduce backlight" option. -- Screen brightness resets to default (half) with battery power https://bugs.launchpad.net/bugs/273446 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
