Comment 8 for bug 179846

I've had a stuck ctrl key that may be related the "hotkeys-setup" service. The following messages appeared in dmesg:

[4335062.871000] atkbd.c: Use 'setkeycodes e02a <keycode>' to make it known.

Disabling hotkeys-setup took care of the error messages, and appears to have solved the problem.
