Some problems with Grub 2 and logging in

[cozmic chris]

Hello folks,
This is my first message to  mailing list.
my name is Chris,   and I am not a trained developer, designer, etc.
I've been  using linux desktop environments on PCs, LT and Netbooks
since 2010. and I have been in love with "open source" since I first
used  "Open Office" around 2001.

I have notice something this week,  that I am not sure is a bug:   when
trying to in install lubuntu 13.10 on an old  Gateway netbook with a
Radeon Graphics processor I ran in to some initial problems...
to at least get some graphics (the graphics scramble after a couple
minutes)  
I edited     /etc/default/grub
line:     GRUB_CMDLINE_LINUX_Default  I added nomodeset
after adding  nomodeset       and updating grub and then rebooting
I could not start the lubuntu session.
I could start an openbox session
I installed the xubuntu-desktop and was able to login to the xubuntu
session,
but not the lubuntu session.

I don't know if this is a bug or not but I thought it was worth
mentioning because  the nomodeset is a good mode for trouble shooting a
propriety  driver issue in set up.
thanks.
