Hi  
successfully moved to puma2, but when I try to run the UMUI this happens.  
Any suggestions?

[vidale@puma2 ~]$ umui  
connect /private/tmp/com.apple.launchd.m1uVICVEKG/org.xquartz:0: Connection refused  
Application initialization failed: couldn’t connect to display “localhost:65.0”  
Error in startup script: invalid command name “option”  
while executing  
“option add \*foreground $colours(enabled\_fg)”  
(procedure “entry\_appearance” line 19)  
invoked from within  
“entry\_appearance”  
(file “/home/n02/n02/umui/umui/ghui2.0/tcl/entry.tcl” line 52)

Hi Pier-Luigi,

Have you managed to get any window open on PUMA2?  
Can you try running `xterm`, for example:

`puma2$ xterm`

It’s working ok from my Macbook Air.

Cheers,  
Ros.
