Is there a way to make
xscreensaver run a single screen saver across the whole X display, ignoring Xinerama/XRANDR geometry?
I have three monitors appearing as a single X screen on one X display. XRANDR provides information about where each physical monitor starts and ends on the single X screen.
xscreensaver uses this to either run a different screen saver on each monitor, or to run the same screen saver three times, once for each monitor.
I would like to change this so that only one screen saver is run, and it spans all three monitors (i.e. it takes up the entire X screen.) This way animations in the screen saver will be free to roam from one monitor to the next.
Is this possible?
