Thanks to Rogue and Ritesh, I made the following changes and all works well: Removed the Modules section (default is to load them all). Added the following: In the Section "Device": Option "NoRenderExtension" "False" Option "AllowGLXWithComposite" "True" Option "RandRRotation" "True" Option "XvmcUsesTextures" "True" Option "AddARGBGLXVisuals" "True" Option "DamageEvents" "True" (These were recommended as options that might be handy.) Added: Section "Extensions" Option "Composite" "Enable" EndSection Now it all works fine.
