Thanks for the link - I've used method 1.
Though investigating i note that I have the 386 kernel and not the 686 ... I don't think that should matter - just means I'll be going through this again a bit later.
I do not have nvidia-settings ... installing nvidia-settings removes the package "nvidia-glx". So I'm leaving it alone for now. I have the 8762 driver and ASUS GeForce nv6600. And, naturally, kver:2.6.15-23-386
Method 2 basically involves using the nvidia installer.
Which is next on my list... only this thing worked in breezy.
I found the following
thread, in which is is commented that render acceleration has a memory leak ... turning this off allows me to run all the examples and any music with goom. DVD intros play... though Totem dosn't support the menue yet. Xine-ui just crashed playing a dvd, taking the entire x session with it. On reboot - the same bahaviour on all media occurred ... but was "fixed" by restarting the x server (re-restarting?)
