Public bug reported:
Binary package hint: gnome-power-manager
hi,
Laptop = Sony Vaio SZ2m-b (Centrino Duo)
until one or two weeks ago my laptop display was darkened when I
unplugged ac and enlightened when I plugged it in again. This is not the
case anymore and now I think it is the time to report the bug.
When I now plug ac in or out there is still this popup showing, that GPM
wants to dim, but after (un)plugging I have to manually dim the display
using Fn+F5 or Fn+F6.
Please note that due to having a small system I have not installed
ubuntu-desktop, but acpi-support which should be enough. I have
blacklistet sonypi, because it produces only errors in dmesg and GPM
doesn't dim even with it inserted. I have only the successor sony-laptop
loaded, and I am quite confused why Ubuntu wants to load both of them.
Will GPM eventually use xbacklight? Besides the Fn-Keys this tool works
well, too.
