Description Ross Burton 2008-01-03 06:57:01 UTC 
Totem on startup gets the screen's randr information so it can resize the screen if it needs to when playing a video, however calling XRRGetScreenInfo() causes an output probe, which means my monitor (connected via VGA) turns off for a second.

This can be replicated with a two-line program:

  Display *dpy = XOpenDisplay (NULL);
  XRRGetScreenInfo (dpy, DefaultRootWindow (dpy));

xserver 1.3.0, -intel 2.1.0, on Debian Sid.

Jesse should have patches for intel driver to get rid of those black screen flashes. 

Jesse, what's current status of your patch?
Comment 2 Jesse Barnes 2008-01-31 02:38:46 UTC 
I've got some early code in my personal tree; hopefully we can merge it along with some other modesetting cleanup in the 2.3 release.

Do you have a TV output?
If yes, I think this bug is a duplicate of  bug 13502.

Thanks,
Hong

I believe that my laptop - a thinkpad x60 - has a tv output.  Recently it was quirked out and I haven't seen this for a while either.  Certainly looks like a dup.
