Well, I forgot to disable my screen locker during an update and got bit
by this again. It's a pain typing it manually (especially when you run a
monitor in portrait mode.)
I had some time and put together a general-purpose bash script. A note
of warning, I'm not an expert at bash by any means, but I was able to
test this several ways as I haven't restarted my computer yet.
I'll attach it if someone else wants to try it out. It's simply called
ck-unlock-session.

# Possible actions:
# -h : Show help screen
# -l : List current consolekit sessions
# -u : Unlock specified session (one parameter required - the session name)
# -a : Attempt to unlock all sessions
# Return code documentation
#
# 0: Script executed normally
# 1: Root access is not present for script
# 2: No arguments passed
# 3: Multiple actions requested, can only do one at a time
# 4: Argument passed was not recognized
# 5: Multiple arguments passed for unlock single session, only one needed
# 6: The argument required for unlocksession() is missing (internal error)

The -u parameter requires a session name to unlock, use -l to list

Example:
To unlock a single session, use:
