I'm running an LTSP server on Ubuntu 11.10 and can load the i386 image via PXE boot on a VirtualBox VM just fine. However, when I PXE boot a Dell FX130 thin client on the LTSP network the login screen ends up being a white screen with a bunch of wavy black lines going up and down it.

The 11.10 splash screen displays just fine as the image is booted, then I get a "INVALID CARD NUMBER" message, then a black screen, then finally the white screen with wavy lines.

I'm not sure if the "INVALID CARD NUMBER" message has anything to do with the issue, but in the end the white screen with wavy lines makes me think it's a video driver problem.

On the LTSP server, I chrooted into /opt/ltsp/i386 and made sure xserver-xorg-video-openchrome was installed. I did notice that no xorg.conf exits in /etc/X11 though.
