xrandr messes up screensaver
Last modified: 2007-04-18 12:57:22 EDT
I changed my resolution in gnome-display-properties to 800x600, loged out and in
again. Now gnome-session set my resolution to 800x600. Then i changed back to
the default size (1024x768), and when the screensaver turned on it was only
covering the top-left 800x600.
alex: How did the resolution get changed? Via the RandR extension?
What does XF86VidModeGetViewPort return (see #81593)?
It returns "0,0", and the viewport is correctly placed at 0,0.
This is pretty easy to reproduce:
xrandr -s 800x600
xrandr -s 1024x768
<wait for screensaver to start, or preview it in the xscreensaver-demo app>
Notice that the screensaver is only 800x600.
Restarting xscreensave fixes the problem. I think xscreensaver needs to listen
to XRandR events so it can know when the screen changes size.

jwz's changelog page has this for the latest version of xscreensaver:
* Added support for the RANDR (Resize and Rotate) extension to detect
when the size of the desktop has been changed while xscreensaver is
I'll roll out new rawhide rpms soon.
This should be fixed in rawhide now.
