From 20c9aa46f644b3ddb161a819d1b0c2b07097c4ee Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 12 Sep 2009 15:22:16 -0300 Subject: thinkpad-acpi: Fix procfs hotkey reset command echo "reset" > /proc/acpi/ibm/hotkey should do something non-useless, so instead of setting it to Fn+F2, Fn+F3, Fn+F5, set it to hotkey_recommended_mask. It is not like it will survive for much longer, anyway.
