Straying off the beaten track, for newcomers to anything, is not recommended. In time one can do it - no doubt about that - too soon is diving in the deep end.
Yes, there can be many, many ways to achieve the same thing. I suggest you try the Ubuntu way, ie Ubuntu nvidia packages. The nvidia installer has this option you should run first,
Code:
--uninstall
Uninstall the currently installed NVIDIA driver.
Install the .debs (which should handle necessary kernel modules) and edit xorg.conf,
- remove the loading of dri module
- keep the glx module
(I'm not sure how Intel graphics handles the above)
- the "Screen" section references a "Device" section by a name you give, it can be "Intel Corporation 82915G/GV/910GL Express Chipset Family Graphics Controller" or "mycard" - up to you - the names you give have to be the same in both places
- your main "Device" section needs to have a 'Driver "nvidia"' (multiple device sections are possible but you will only use 1 at a time)
- reboot to enable the nvidia card in bios
- "startx"
