-grab_buster Some of the use of the RECORD extension can leave a
-nograb_buster tiny window for XGrabServer deadlock. This is only if
the whole-server grabbing application expects mouse
or keyboard input before releasing the grab. It is
usually a window manager that does this. x11vnc takes
care to avoid the the problem, but if caught x11vnc
will freeze. Without -grab_buster, the only solution
is to go the physical display and give it some input
to satisfy the grabbing app. Or manually kill and
restart the window manager. With -grab_buster, x11vnc
will fork a helper thread and if x11vnc appears to be
stuck in a grab after a period of time (20-30 sec)
then it will inject some user input: button clicks,
Escape, mouse motion, etc to try to break the grab.
-debug_grabs Turn on debugging info printout with respect to -debug_grabs Turn on debugging info printout with respect to

Some of the use of the RECORD extension can leave a
tiny window for XGrabServer deadlock. This is only if
the whole-server grabbing application expects mouse
or keyboard input before releasing the grab. It is
usually a window manager that does this. x11vnc takes
care to avoid the the problem, but if caught x11vnc
will freeze. Without \fB-grab_buster,\fR the only solution
is to go the physical display and give it some input
to satisfy the grabbing app. Or manually kill and
restart the window manager. With \fB-grab_buster,\fR x11vnc
will fork a helper thread and if x11vnc appears to be
stuck in a grab after a period of time (20-30 sec)
then it will inject some user input: button clicks,
Escape, mouse motion, etc to try to break the grab.
