I'll have to try again with .39, the xorg and dri and kernel were at
the latest versions (and even tried experimental) at the time I

screensaver in random mode, and unfortunately the logs don't record
the info I need to determine screensaver (is there a way to get
xscreensaver to log each screensaver it uses?) in use.
