Package: xscreensaver
Version: 4.21-3
Severity: wishlist

Some hacks crash / fail for me.  Most notably all the GL ones, since I have
recently run into problems with my nVidia drivers.  That a hack fails is not
necessarily because the hack itself is broken.

When a hack crashes / refuses to run, it seems to me that XScreensaver doesn't
really react to this in any way.  I have XScreensaver set to change hack every
two minutes, and AFAICT even the GL hacks that simply print...

... then exit with an error code stay on the screen for two minutes.

Instead, I would prefer if XScreensaver kept a black list of dysfunctional
hacks.  When a hack fails in a measurable way (such as exiting before told to,
with or without an error code), it should be added to the black list.

All hacks on the black list should be ignored when choosing the next hack to
run.

This would make my screen display more screen savers and less error messages
when I don't use it.
