Comment 33 for bug 227717

Update of kernel to version 2.6.27.1 (Intrepid) today resulted in error msg nvidia: fail, resolve manually (I write from memory, thats not verbatim msg).

After that I tried envy, and get as above "envynggtk.py crashed with ImportError in <module>()"

I tried procedure you wrote above:

1.sudo apt-get --purge remove envyng-core
2.sudo rm -R /usr/share/envy
3.sudo apt-get install envyng-core
4.envyng -t

All went well, kernel at boot again loaded 177 module, everything is ok (and I know to test envyng in text mode next time before I start googling :-))
