## Touchpad

Install xf86-input-synaptics to get multi-touch gestures working.

## Keyboard backlight

Currently the `thinkpad_acpi` module does not support to turn the keyboard backlight on. But you can turn it off with:

    # echo 0 > /sys/devices/platform/thinkpad_acpi/leds/tpacpi::thinklight/brightness

## Suspend

Works flawlessly with with pm-utilsAUR or any DE integration. If resuming from suspend works once but not a second time, try disabling Intel's Anti-Theft module in BIOS (see this kernel bug report).
