[Bug 42406] When no Direct Rendering is available, OpenGL screen savers use CPU very much

[Oliver Gerlich]

Public bug reported:

Affects: gnome-screensaver (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


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
