The picture posted by Flash suggests xserver can't get root permission. Before proceeding with the firmware and vesa solutions, I'd first try the following:
Run BionicDog again. When it halts, run:
Code: Select all
apt-get update && apt-get install xserver-xorg-legacy
startx
Code: Select all
echo "needs_root_rights=yes" >> /etc/X11/Xwrapper.config
startx

Edited the tip to be a little bit more nuanced.
