ok this is so dame simple, have been locking for a solution for months.
this is how you get g210m to work on ubuntu 9.10 / 10.04.
1. download and install nvidia drivers. (i have only tested the ones in the repos)
2. make sure you got an Xorg.conf that is correct. ( if not, run nvidia-xconfig )
3. reboot into bios (press delete while booting)
4. change the SATA option in the bios from enhanced to compatibility. ( yea, this makes sense? NOT! )
5. boot into linux and smile!
Anyone more then me who want to hit the people who wrote the bios?
running the latest bios. ends with 10.
