I have a T60 with BIOS 2.1 and firmware 1.7 (according to dmidecode).
I am suffering from the problems you described in your earlier email.
Namely, fn-end and fn-home both work correctly to turn the brightness
up and down, but only fn-end (brightness down) is picked up by tpb.
fn-home generates the following acpi events:
Jan 1 09:46:23 calvin logger: ACPI event unhandled: ibm/hotkey HKEY
00000080 00001010
Jan 1 09:46:23 calvin logger: ACPI event unhandled: video LCD0
00000086 00000000
I do not have any confusion between fn-f7 and fn-home. `echo {4,5} >
/proc/acpi/ibm/cmos` work correctly to turn brightness up and down,
and tpb displays the results of both.
Can you recommend any immediate course of action?
Thanks for your work.
