Description Bastien Nocera 2013-12-12 00:28:24 UTC 
When the screen is DPMS'ed, also turn off the touchscreen.

We should also do that when disabling outputs, and not just for touchscreens, but also for wacom tablets (such as Cintiqs).

common: Fix possible crash in GsdDeviceMapper

If the input device isn't known to the device mapper (say a keyboard for
example), we'd crash trying to check which output it was attached to.

power: Disable touchscreens when turning off its screen

For example, turning off a tablet's touchscreen when the screenlock
kicks in.
Comment 4 Bastien Nocera 2014-07-26 12:24:59 UTC 
The reason why I'm not pushing that is because X.org seems to replay a bunch of touch events when turning the screen back on, leading to very bizarre behaviour.

I can reproduce the problem by doing:
xinput disable 9 ; sleep 5 ; xinput enable 9

With 9 being the device ID for the touchscreen.
