Comment 10 for bug 174191

> my first action on any new install is to select one of the low CPU screensavers as my default to prevent CPU burn out.

As mentioned in the other bug, the default is "Blank screen"

Your computer locking because of the screensavers is really the fault of your proprietary graphics drivers. However I am not gonna say that they should be removed from the repository :) Well, they are not in the main repo, but only in the "restrictive" anyway. The collection of screensavers (especially the 3D ones) can be a real stress test for the drivers since they ask things from the card that for instance your text processor would not.

Of course we try to sort out which screensavers are performing bad in general, but if they only break with one, proprietary graphic driver, I guess it is the driver that should be fixed. Which we ourselves can not do, since they are made in secrecy by the same people who sold you the hardware. Maybe they have a bug tracker where you can report these problems? So unless Nvidia starts working with the open source community like Intel and ATI do, I can not see any good solution. We could maybe disable all screensavers when we detect the nvidia driver... But again, the default is blank screen anyway.

The nvidia driver specific crashes are submitted in bug #110125.
