I am running Ubuntu Server 8.04 (no desktop). I've installed the
3.10-4 VM via the included INSTALL script (after changing to root).
I am able to launch an image headless just fine:
squeak -vm display=none myImage.image &
Now I want to run an image and display it on my remote laptop. I ssh
-X into the Ubuntu server box, but when I try to launch the image:
squeak myImage.image &
squeak: could not find any display driver
Make sure it is not a permissions issue:
sudo chmod -R 777 /usr/local/lib/squeak
Make sure it looks right:
ls -l /usr/local/lib/squeak/3.10-4/vm-display-X11
"-rwxrwxrwx 1 chris chris 217882 2008-11-10 18:43
/usr/local/lib/squeak/3.10-4/vm-display-X11"
Ok, it's there now with open permissions. Try again:
squeak -vm display=X11 myImage.image &
Same result. Try exporting my DISPLAY:
export DISPLAY=192.168.0.4:0.0
squeak -vm display=X11 vanilla.image &
Now I get a different message:
could not find display driver vm-display-X11; either:
- check that /usr/local/lib/squeak/3.10-4/vm-display-X11.so exists, or
- use the '-plugins <path>' option to tell me where it is, or
- remove DISPLAY from your environment.
Ah ha, could the problem be it is looking for a .so extension on the
plugin? Copy it to that name too:
cp -p /usr/local/lib/squeak/3.10-4/vm-display-X11
/usr/local/lib/squeak/3.10-4/vm-display-X11.so
I still get the same result, but it's tellling me to remove DISPLAY
from my environment..? Ok, done.
Shoot, back to the old message:
squeak: could not find any display driver
Now I try the same thing against a different server, a Ubuntu 8.04 (desktop).
xhost myServer
ssh -X chris at myServer
squeak myImage.image &
It works just fine, the image displays and operates on my laptop! So,
it would seem some installation problem on my Ubuntu *server* edition.
I'm starting to pull my hair, anyone have any ideas?
