Comment 7 for bug 330258

For some reason I have again problems with this.

The nvtest script gives as error:

Traceback (most recent call last):
  File "/tmp/nvtest.py", line 9, in <module>
    backend = NVidiaSwitcher()
  File "/usr/share/disper/src/switcher/swnvidia.py", line 32, in __init__
    self.nv = nvidia.NVidiaControl()
