Bug Description
I have tried both going into the system preferences and using the hardware adjustment ( function key + the left or right arrow key ) It used to work on the older Ubuntu 9.10 version. Please stop dropping the drivers for hardware. Especially for hardware that is barely older than 1 year. I am currently on 10.10 if that is not in the report. If Linux is to gain ground hardware support is crucial. And things like screen brightness is basic, much less printers, webcams, and other peripherals. I am not a advanced user at all. I am just a previous basic windows user trying to both switch to and support Linux.
Thank you and God Bless,
Daniel Clem

This is also happening to Acer Aspire Timeline 5810T and 4810T on Ubuntu 9.10, 10.04, and 10.10.

I tried "Step-by-step Troubleshooting" from https:/ /wiki.ubuntu. com/Hotkeys/ Troubleshooting
The Fn+Right/FN+Left (brightness down/up) keystrokes appears in Terminal (step 2 from link above) so the buttons work, system recognizes them.
*** But after pressing Fn+Right/FN+Left Ubuntu 10.10 completely freezes and I have to hard reset. ***
Pressing touchpad button stops operate touchpad, yes, but until next restart you cannot re-enable it. Same behavior is under Windows, this seems to be a BIOS bug.
