exporting Squeak's DISPLAY to another machine?

exporting Squeak's DISPLAY to another machine?
 
|
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@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? - Chris |

Chris,
I don't know if this will help you but I could imagine you try to connect a root server that has no graphic card?! I had to do this once ago and used therefore the virtual X-Server xvfb which was then connected via VNC with X11vnc. I did this with VMware workstation but it should work also with Squeak. E.g. to start a xterm this way I did /usr/X11R6/bin/Xvfb :1 -screen 0 1024x786x24 -fbdir /tmp :1 export DISPLAY=localhost:1; xterm & x11vnc -display :1 and from remote connect with a VNC client my-ip-address:5900 to the virtual X-Server.

I have never exported manually the DISPLAY variable.
I install only the basic packages (no X11 or desktop environment). Then I install by connecting with ssh the package aptitude install xbase-clients and after that I connect with: ssh -X user@server and run the program squeakvm my.image & and is shown in my local laptop but running on the remote server.

Hey Chris,
The last time I had that problem with vm-display-X11 I ran through a similar odyssey. I ended up running the squeak-vm through strace and it turned out to be libGL.so.1 (IIRC), the 32-bit version of it. Once I created a symbolic link in /usr/lib32/ everything was fine.
