When running in Xephr, we are not doing a full emulation of a device,
but instead just running the stack from inside a chroot, so there are
various ways that you can break the model (like running software that
depends on specific hardware.)

One of the issues that we run against is that somehow the gconf system
is connecting to the gconf deamon from your workstation. The marquee
drop down list (with the exception of the catch-all category) is
populated from a gconf key, and since you don't have that key on your
desktop gconf settings then you see only 'All.'
You can work around this by running 'killall gconfd-2' before starting
Xephyr, but this exposes some bazaar side effects on your desktop
system.

The games are trying to use OpenGL, and your Xephyr server is not
exposing those X extensions.
People have shown that it is possible to build a Xephyr that enables
OpenGL capabilities, but nobody every push the changes into Ubuntu.

The ctrl-alt functionality was provided via your desktop window manager,
not the window manager matchbox running inside Xephyr.
But... matchbox can do this. We might just be missing a configuration
file to map matchbox hotkeys.
