Hmm.. according to Lenovo/IBM web pages the latest BIOS for my X60 tablet is 1.09. What I have is 1.04. How do these versions relate to 2.x? > 2a.

I booted to my miniroot and the brightness control works (Fn+Home/End changes brigthess level) without ibm-acpi/video/hal/hotkey-setup/gnome but of course without ibm-acpi I cannot observe any indications about what the SW thinks about the level :-) > 2b. rmmod video, modprobe ibm-acpi (if not loaded), make sure HAL is not > running. > > 2c. test brightness keys and /proc/acpi/ibm/brightness functionality. > > It should work just fine, from reports of some X60 owners. For me the control works (i.e. Fn+Home/End changes brigthess level) but the _indication_ in /proc/acpi/ibm/brightness stays unchanged. I can also control the brightness via echoing to /proc/acpi/ibm/brightness and then (as expected) the indication also changes. > 2d. modprobe video > > 2e. test brightness keys and /proc/acpi/ibm/brightness > > It is expected to break in weird ways.

If I rmmod video, the control does not work any more. If I modprobe video again, the control starts to work again. But the control does work without video module before it is loaded for the first time! > 3. load up HAL, and *only* HAL (not gnome) > > 4. test brightness functionality. Do they work fine?
