Re: XFree86 lockup with screensaver


(Another thread from a few months ago)

Thanks for this info Igor...

We weren't able to reproduce my coworker's problem until he hit it again
today.  I had him run "xev -display :0.0" from a separate cygwin prompt
while this was happening, then everything suddenly became responsive and he
could see his xterms again.  Maybe xev tickled something.  FYI for anyone
else that hits this problem.
