Thanks for the command xhost the problem terminate.
Now when i run pgaccess result:
Error in startup script: coudn't load file "libpgtcl.so":
/usr/lib/libpgtcl.so: undefined symbol: crypt
while executing "load libpgtcl.so" (procedure "main" line 6) invoked
from within
"main $argc $argv"
(file "/usr/bin/pgaccess" line 4954)
so i can't run .
Thanks
