| |
Hi there,
With latest git kernel, I'm no longer able to control my Thinkpad (W500) brightness, although I can still control the backlight, bluetooth etc.
I originally got some errors (below), but I was able to get around them by changing /etc/modprobe.d/thinkpad_acpi from the (default OPENSUSE) options thinkpad_acpi experimental=1 hotkey=enable,0xffffff to options thinkpad_acpi experimental=1
Any ideas on how I can regain control over the brightness gas-pedal?
Niel
