Display is darker after suspension and hibernation

Bug Description

Binary package hint: gnome-power-manager

OS: Ubuntu 9.10 x64.

After I awake my laptop after suspension or hibernation, the display is darker than normal (reduced backlight/dimmed) and remains darker, until I log off, when it becomes vivid again. Then I log on, and it is OK.

However this means that suspension or hibernation is not an option, since I will have to log off because of the issue.

I am posting with this message, my current power management settings, as screenshots.

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of GNOME Power Manager is available on Maverick and we are wondering if this bug is still an issue for you with that version? Could you please test and comment back? Thanks in advance.

There is still an issue under 10.04 x64.

I have not a 10.10 installation in this laptop, however I just tested suspension with the 10.10 x64 Live DVD, and it did not come back from suspension OK (only the mouse pointer was visible, and switching among consoles was working, and I rebooted from a console).

Laptop is Acer 8920G with the latest BIOS update.

Are you using the hardware drivers for this system? Please run
    sudo lspci -vvnn > lspci-vvnn.log

in a terminal and attach the lspci-vvnn.log to this report. This may be a video driver issue instead of gnome-power-manager issue. Thanks in advance.
