Bug Description
[this bug is for the wishlist]
On machines where OpenGL doesn't use Direct Rendering (eg. because the nv driver is used, or because the hardware doesn't support 3d acceleration), OpenGL screen savers run only on the CPU and cause very high CPU load.
I think it would be nice if gnome-screensaver wouldn't run any OpenGL screensavers when the mode is set to "Random". Currently I have to explicitly select a 2d screen saver (or empty screen), but I think it would be better if gnome-screensaver would take care of that.
Thanks,
Oliver
