Binary package hint: gnome-power-manager
Hi, I'm on a Thinkpad R60e, using Hardy, and gpm is version 2.22.1-1ubuntu4.
My problem is that occasionally, my laptop will just turn the screen up to full brightness, most noticeably when I'm trying to play a movie or doing anything after a short period of inactivity. I've looked around a little, and I think I see the problem. This is gpm's log just after I pressed a key after leaving the computer alone for half a minute.

Apparently this is where something goes wrong:

Disabling the screensaver doesn't help. Are there any workarounds until this is fixed? It's rather annoying, because I don't like reading at full brightness (and it's harder on the battery).
Thanks in advance!

Could you please include the log before this. GPM should have dimmed
the display when it thinks you are idle, and then renewed the setting
when you come back. That's the expected behavior.

You can turn off idle dimming by deselecting "Dim when idle" in
System-
