Under X, if the RANDR extension is supported, you can use the Xrandr(3x) library to get and set the refresh rate for a screen (as well as changing screen size/modes). You ought to be able to query the current screen config before making modifications, and restore the original config later. The upcoming RandR 1.2 (will be part of the X.org 7.3 release) will also support display hotplug and run-time (re-)configuration of multi-head setups (also requires driver support). -- Leif Delgass [EMAIL PROTECTED] _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
