I have an older Gateway 510x and I recently installed a GeForce 6200 card and upgraded fine to 11.10. However due to hibernate and wakeup problems and indication's that this could be due to the Nvidia driver, I, in my infinite wisdom, removed the driver and am now dead in the water - won't boot. I can get to the Grub splash screen (I also have a MS Windows 7 partition).
How do I reinstall the driver if I can't boot? I can come up with my 11.04 live CD. I am not expert at this and am 70 years old so complete explanations would be helpful.
