lxc-start seems to reset properties of input devices

[Guilherme Salgado]

I change some properties of my trackpoint (via xinput) upon logging into unity, but when I lxc-start a container those properties are reset to their original values:

salgado@delgadito:~$ xinput --list-props pointer:"Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" | grep "Device Accel Velocity Scaling"
 Device Accel Velocity Scaling (257): 60.000000
salgado@delgadito:~$ sudo lxc-start -n launchpad -d
salgado@delgadito:~$ xinput --list-props pointer:"Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" | grep "Device Accel Velocity Scaling"
 Device Accel Velocity Scaling (257): 10.000000

Thanks for reporting this bug. It's known, and caused by your container running udevadm trigger. If you have precise containers, they will avoid running udevadm trigger to prevent that happening. You can update your containers by hand to do that otherwise.

I'm going to mark this a duplicate of bug 948447.
