The requestor's log file entry has nothing to do with signals; it's just setting "display" to reverse video, outputs "interrupt", and resets to normal video (given that ^M stands for "Escape", which, I admit, may be a wild assumption).

xscreensaver-getimage-video

xscreensaver-getimage-video(1)					XScreenSaver manual				    xscreensaver-getimage-video(1)

NAME

       xscreensaver-getimage-video - put a video frame on the root window

SYNOPSIS

       xscreensaver-getimage-video [-display host:display.screen] [--verbose] [--stdout]

DESCRIPTION

       The xscreensaver-getimage-video program is a helper program for the xscreensaver hacks that manipulate images.  Specifically, it is invoked
       by xscreensaver-getimage(1) as needed.  This is not a user-level command.

       This program grabs a random frame of video from the system's video input, and then loads it on the root window.	It does this  by  figuring
       out  which  frame-grabbing  programs  are  installed on the system, and invoking the first one it finds.   Then it runs xscreensaver-getim-
       age-file(1) to load that image onto the root window.

OPTIONS

       xscreensaver-getimage-video accepts the following options:

       --verbose
	   Print diagnostics.

       --stdout
	   Instead of loading the image onto the root window, write it to stdout as a PBM file.
