Nvidia 331.20-Oubuntu1~xedgers~saucy1 breaks ksnapshot

[James]

RELEASE : Ubuntu 13.10 (saucy)

331.20-Oubuntu1~xedgers~saucy1 appears to break ksnapshot.

ksnapshot will open and appear to operate correctly . However, after snapshot is taken, the result is a "black" blank photo.

I tested this by going back to an earlier kernel which did not include nvidia 331 and testing ksnapshot and it operated correctly -- then reinstalling nvidia 331 (It was installed using synaptic and I believe it was from http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu ) -- Retested ksnapshot at this point and it was then issuing the above referenced "black" blank photo. There were no other changes made in the interim.

The same output results when using another screenshot program -- kgrab.

Driver version 331.20 has a known bug which breaks signal processing entirely, resulting in various abnormal behaviours.
