I cannot enter my desktop after an update last night. I realize that they was add another release version(lines) in the GRUB. How can I fix the problem? should I run update again using recovery mode? If so, how?

What Ubuntu version are you using? Is it a clean install or an upgraded one from an earlier release (to see if you have grub or grub2)? –  papukaija Jan 28 '11 at 2:08
    
Ubuntu 10.10. It was clean install. GRUB 1.98 –  napi Jan 28 '11 at 14:20

I have a laptop Acer 4552 with a GPU ATI HD 4250 and after I upgrade from my former kernel to the current I run into this trouble.

I resolve doing the following:

1.- boot on recovery mode in the low graphic mode

2.- Because I have already my driver downloaded I just run the configuration and the reboot. This will cause the GPU driver to be updated to the current kernel and then be able to boot.

Updating my kernel also fixed my hang up problem when I put on suspension and be able to use it again.

I hope this information to be useful to someone. Cheers
