Acer Aspire Timeline 4810T laptop and Backlight Control, part 2.

I have GREAT news for the 4810T owners the 2.30 BIOS[1], we now have backlight control keys working

There is a catch after you upgrade[2] to the 2.30 BIOS you will get a freeze type effect on the desktop (well I did). Also I noticed that my WiFi went funny to and I could not ping anything even tho Net. Mgr. was say I was connected to AP.

So DON’T play with backlight key till done the below changes.

You have to change from

xrandr –output LVDS –set BACKLIGHT_CONTROL native


xrandr –output LVDS –set BACKLIGHT_CONTROL kernel


xrandr –output LVDS –set BACKLIGHT_CONTROL combination

[2] Howto BIOS Update
