Acer Aspire Timeline 4810T laptop and Backlight Control, part 2.
Posted by Quail in Debian, Hardware, Howto, LinuxI 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
to
xrandr –output LVDS –set BACKLIGHT_CONTROL kernel
or
xrandr –output LVDS –set BACKLIGHT_CONTROL combination
