Public bug reported:
Binary package hint: kde-guidance
guidance-power-manager cannot set the backlight of my Dell Latitude D620
notebook computer. The module dcdbas is loaded.
I get the following error message:
Warning: in getBrightness(): org.freedesktop.DBus.Error.NoReply: Did not
receive a reply. Possible causes include: the remote application did not send a
reply, the message bus security policy blocked the reply, the reply timeout
expired, or the network connection was broken.
