When I first installed 10.10 I actually used your PPA for the
-lowlatency kernel. Yes, it was for Natty as was recommended by
several posts I found, but as you mentioned, the nvidia drivers didn't
work. If I understand correctly there must be three sets of drivers
for nvidia cards now:

nvidia - FLOSS
nvidia - proprietary

Am I correct in saying that by default the FLOSS drivers will be
installed? How would I remove the FLOSS drivers and go back to the NV
drivers if I want to install your -lowlatency kernel? Will the NV
drivers support the GeForce 8600GTS card?

Yup, that is the one fix I installed first.

Yes, I've used a combination of envy24control and alsamixer. I would
imagine that since I've got sound from Jack etc that I've got the
correct channels un-muted and volumes up (but it wasn't easy
understanding what was muted etc.)

That would be the PPA I used for the kernel stuff.

I'm thinking what I may do first is reinstall a clean 10.10 system and
get the NV driver working. Then install the -lowlatency kernel from
your PPA. Then get the 1010lt working with the onboard card disabled.

Thanks again for your help.
