Some problems with Grub 2 and logging in

Hi thanks for e-mailing us about this.
Do you have the proprietary drivers installed, or are you using the open
source drivers?
I have an ATI Radeon GPU on my notebook and it works just fine.  It
seems odd that nomodeset would cause Xubuntu to work and not Lubuntu...
So, the first thing that will help is giving us a bit more info...
can you post the specific graphics card?
run this command form the ternimal:

 lspci | grep VGA

lspci lists all the pci devices, and grep searches the results for VGA.

We also would benefit from knowing exactly what processor arch and
kernel you are using.

uname -a

will list a lot of info which you can paste in an e-mail, however... so
you can just run

uname -r -p

which will print out the kernel version and processor arch.
I put both in because they are useful to know :)  And you may very well
already know these commands.
Someone on this list may have specific insight (having dealt with this
exact problem), but either way this info will help us to help you better.

And it may be that you simply need to clear your ./config and ./cache,
though I'd suggest backing them up before removing them.
But post your info first to see if there is an issue someone else has
dealt with specifically.
