Seeing the following and wondered if it is particular to my installation?
Automount of USB drives no longer works from console
unix-user = '12345678'
realname = 'joe'
seat = 'StaticSeat1'
session-type = ''
display-type = 'Local'
open = 'TRUE'
active = 'FALSE' <== Seems to be the problem
x11-display = ':0'
x11-display-device = '/dev/tty1'
display-device = ''
remote-host-name = ''
is-local = 'TRUE'
switch-user to the same user and active goes to TRUE and USB drives automount again.
However, that's not a good workaround as logging out from the switch-user session seems to cause ConsoleKit to crash.
Screen goes to black with a flashing cursor (i.e. no greeter screen).
