View Full Version : [kubuntu] Sony Vaio Fn keys (brightness) not working

October 31st, 2011, 08:46 AM
hi guys. I've just installed kubuntu 11.10 -clean install- and the only problem I face now is that the fn keys for +/- brightness are not working. I followed some guides in this forum to set the acpi off in the grub and to add a line to the grub but I still can't control the brightness of the monitor. Any idea?

Things that I've already did:

> Checked acpi-support: installed
> acpi_osi=linux, off acpi_backlight=vendor in grub: not solved
> Option “RegistryDwords” “EnableBrightnessControl=1″ added in xorg: not solved

Anyone to help?
Thanks in advance
