Hello all: I've been using Gnome since I installed FC1, several months ago, and didn't realize until now that screensavers, especially those using 3D graphics, flicker annoyingly, at a rate which seems affected by the refresh rate. /sbin/lspci shows: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R100 QD [Radeon 7200] (rev 01) X11/xfree86config: Section "Device" Identifier "Videocard0" Driver "radeon" VendorName "Videocard vendor" BoardName "ATI Radeon 7200" EndSection I tried changing driver to ati, without any change. glxgears runs with the results 4368 frames in 5.0 seconds = 873.600 FPS which is comparable to the numbers I get with Gnome. I'm out of ideas -- any help? Scott
