gnome starter

[io]

According to a suggestion from Andrea, I used a simple .xinitrc:

exec twm
/opt/local/bin/metacity &

Then in MacOsX terminal by command startx below I had:

To execute a file of the current directory use ./
io in ~ $ startx
font_cache: Scanning user font directories to generate X11 font caches
font_cache: Updating FC cache
xauth:  file /Users/io/.serverauth.45702 does not exist

May be this gives any useful information?
