Bug Description
Binary package hint: gnome-power-manager
I am having trouble after resuming from suspend to RAM on one of my laptops. This is on Lucid - it used to work perfectly on Jaunty.
This bug, which is a spin-off from bug #510004, concerns the power manager: after resume from suspend it seems to think that the laptop is now running on battery power, so it dims the screen, even though the machine is still connected to the mains.
This is reproducible on one of my laptop machines. On the second one, I have not observed this behavior.
How to reproduce:
0) Make sure you are logged in to Gnome.
1) Make sure your computer is connected to the mains.
2) Suspend to RAM.
3) Resume.
Expected behavior: The display should retain the same brightness level as before.
Actual behavior: The display is dimmed.
