[SunRay-Users] xlock screen locking -

From previous description, it appears that he had a
hung xscreensaver *as well as* an xlock program
running. My guess is that it was the xscreensaver
that had the grab, so the xlock was actually blameless.
If xscreensaver is hung, and doesn't respond to
xscreensaver-cmd when it tries to lock it, utxlock
will incorrectly conclude that there is no xscreensaver,
and will run xlock. I believe this is what is occurring
in this case, which is why I asked Matthias to (the
next time the problem occurs):
- verify that an xscreensaver is running for that display
- try xscreensaver-cmd to communicate with it
My guess is that xscreensaver-cmd will fail.
