Well, I'm kinda disappointed with Ubuntu so far...

I was looking at the dependencies for the ubuntu-mobile package, it is very heavy... it demands that you install all of xorg and hardware OpenGL, and won't let you install OpenGL software rendering (the only kind we can use on the tablet) instead...

I tried to set up the secondary LXDE desktop in Ubuntu, and they seem to have messed with the Xephyr x-server. It ignores the "-parent" parameter, so I can't put it in my host window, and it has some new parameters for hardware acceleration... I'll probably have to copy over the Debian version of Xephyr to get things working...
