Description Ross Burton 2010-02-08 04:42:27 UTC 
gnome-screensaver 2.25.1 uses the sync extension in xext to detect idle. It installs multiple alarms so that it can fade the screen without locking and then lock after a few seconds, allowing the user to notice the fade and cause activity without having to unlock.

However, with xorg 7.5 (replicated with both xserver 1.7.3 and .4) only the initial alarm fires.

To replicate, download gnome-screensaver 2.25.2 from:

http://ftp.acc.umu.se/pub/GNOME/sources/gnome-screensaver/2.25/gnome-screensaver-2.25.2.tar.gz

Then configure, make, and run src/test-idle-monitor.  This installs three timers at 2.5s, 5s and 10s.  Only the 2.5s time will fire.

Is this still an issue?  Was this behaving as you expected in an earlier server 
or libXext?  If so, what was the last version that behaved that way?
