Find hardware events¶
The ThinkPad X220 Tablet has a hardware sensor that registers when the screen
is turned around. To find the code of the event, use
$ acpi_listen video/tabletmode TBLT 0000008A 00000001 video/tabletmode TBLT 0000008A 00000000
I started the command, turned the screen around, flipped it onto the keyboard and back again.
This then goes into an ACPI hook file like so:
event=video/tabletmode TBLT 0000008A 0000000 action=/usr/bin/thinkpad-rotate-hook %e
If you give us the output of
acpi_listen, we can try to get the hardware
event working for you. The hook in
tps/hooks.py needs to be made aware of
the hardware keys as well in order to decide which action to take.
