You could just run eclipse on the domU and tell it to use your leisure
computer as its display. No need for GPU access on the domU.

- From your desktop environment on your leisure computer, open a command
window and run

ssh domU

now you can try running eclipse and if all goes well it should open
it's windows on your leisure computer. You may want to start by trying
to run xterm to test the display use, just in case eclipse has it's
own issues.

If not, then you have some debugging to do.

Some common problems are:

1) Ubuntu does not allow network connections to your display by
default. You should be able to turn this on through whatever control
panel you have available. If not, you'll have to dig into the
configuration files of whatever display manages you're using. For
exanmple, for gdm, you set DisallowTCP=false in /etc/gdm/custom.conf
Tunneling through ssh may bypass this issue.

2) SSH may not be configured to tunnel X windows. Check if the DISPLAY
environment variable is set. If tunneling is setup it should look like
'localhost:10'. Change the option in /etc/ssh/ssd_config on the domU
and restart ssh.
