Comment 13 for bug 1194568

I also tried running this little C program below to print the X server idle time. I was curious if the idle time was increasing even though I was typing.

It's odd, but the idle time appears to be staying quite low:

$ while : ; do echo "$(date) : $(./xprintidle)"; sleep 10 ; done
...
Thu Feb 7 13:28:59 CST 2013 : 1310
Thu Feb 7 13:29:09 CST 2013 : 7
Thu Feb 7 13:29:19 CST 2013 : 6711
Thu Feb 7 13:29:29 CST 2013 : 911
...

The screensaver kicked in at 13:29:08 even though the idle time was no more than 11.3 seconds, and my xscreensaver timeout is at 60 seconds (normally it's 5 minutes, but I reduced it to 1 minute for debugging).
