I've seen lots of threads regarding this issue. The main resolution seems to be to add
to the /boot/grub/grub.cfg and then run
sudo grub-mkconfig -o /boot/grub/grub.cfg
It doesn't seem to be helping. I just upgraded to 11.04 (on my way to 12.04). I have this thing configured and need to avoid a complete re-install.
I have an Nvidia card.
I would really appreciate your help.
