Does refomatting change my installed drivers?

Question

I installed or updated nvidia drivers to support 3d or glx (something like that) in my Ubuntu 9.10...and now it's perpetually in Low-Graphics mode.

I tried to fix it but now I just want to do a clean reformat.
Does reformatting change the drivers back to normal (and rid me of the driver that has plagued my system with "Low-Graphics mode")?

Answer 1

Reformatting will erase your current filesystem and therefore Ubuntu. Then re-installing Ubuntu 9.10 will restore your drivers (and everything else) to the same state as when you previously did the install. Make sure you back up any documents and settings you would like to keep beforehand.
