(mdeslaur):
CONDITION:
settings > keyboard > hotkeys > next source: Caps Lock
# suppose num lock can be effected too
# Mod2+Caps Lock or Caps Lock doesnt matter
HOWTO:
1. lock screen with super + l
2. press caps lock then unity will blink and you will see desktop for a half
a second or so. on that period do clicks anywhere in window. on success unity
lock screen wont reappear and you will be inside.
BTW:
sometimes it works from 1st try, sometimes need some pron with clicking
after i done it on working machine i retried on virtualbox fresh installed
without any encryption. Works too.
i use hp probook 450 g1 hasswell. graphic card is intel builtin.
EXPECTED:
on pressing caps lock next source switch
HAPPENED:
