When trying to run the pharo vm on a 64bit Ubuntu, I get the following:
$ pharo Pharo.image
could not find display driver vm-display-X11; either:
- check that /usr/lib/pharo-vm//vm-display-X11.so exists, or
...
The file /usr/lib/pharo-vm/vm-display-X11 (without .so) exists already. If I also create a symlink, the problem is still around. What could be the problem please?
