Re: ./nvidia-installer: not found, Ubuntu 9.04
I think your huuuugely complicating things here.
Why are you running a 64bit kernel on 32bit ubuntu install? Why are you using a custom kernel/custom nvidia installer/envyng to install a driver which is readily available in your distribution? You should have the nvidia binary driver up and running graphically within a minute of installing ubuntu.
If you wanna grab a newer driver than 180 you can get them from the nvidia-vdpau ppa (and or upgrade to 9.10).
