OK, this suggestion about the DISPLAY variable worked fine (it required the
localhost:0 option. thanks Dieter!). Now PD starts up and I get a new error
message: Audio I/O stuck and then it shuts down, usually leaving a window in
gnome which must be "annihilated". Starting with the -nosound option seems to
make no difference. Still doesn't work, although PD seems to make it much
farther through the initialization routine now. Audio and midi both work under
x-windows with other programs. Is this something to do with the frag option?
