Description Peter Williams 2007-11-10 05:54:36 EST
Description of problem:

Certain keycode mappings are supposed to set up by HAL through the "ThinkPad
Extra Buttons" input device. See
fdi/information/10freedesktop/30-keymap-module-thinkpad-acpi.fdi. On my
computer, a T61, the Extra Buttons device is registered by the thinkpad_acpi
kernel module, but for some reason HAL discards the device. 

Version-Release number of selected component (if applicable):


Additional Information:

HAL is definitely detecting the input device corresponding to the Extra Buttons,
but he input probe on it is failing for some reason. The relevant verbose output
of HAL is:

I can't figure out a way to determine why the prober is failing for this device.

Comment 2 Richard Hughes 2008-05-30 07:37:36 EDT
Should be fixed in F9, now the thinkpad-laptop driver had been un-fubar'd.
Please confirm.
Comment 3 Peter Williams 2008-05-30 12:46:13 EDT
I see the "Thinkpad Extra Buttons" in the output of lshal now, so I think this
is fixed. To be honest I forget exactly what problem this bug was causing for
me, or whether I found a workaround for whatever that problem was, but it's
probably fine.
