I've recently installed ubuntu 10.10 alongside windows vista as a dual-boot on both of my computers. This question pertains to my acer aspire 5735Z. I'm quite new to ubuntu, so I'm sure I'll be needing a lot of help.
I've been having problems with the screen brightness and the screen brightness application. When first installed I had no problems at all, but now the screen seems to be locked at around 50% brightness. When I click on the screen brightness application icon on the panel and try to change the brightness, my mouse cursor freezes and/or moves verrrry slowly for 30-90 seconds, then comes back to normal. Key commands are also suspended after attempting to adjust brightness.
I've tried adjusting the 'power management preferences', and have the display brightness set to 100%, but the screen is still dark.
I've tried opening 'gconf-editor'/apps/gnome-power-manager/ and setting all applicable settings to 100%. Still dark.
