With 'sudo' you should not have this issue.
I agree, though, that having a separate user account to install
crystallographic programs is quite an advantage from an administrative
point of view.

Stuart,
Are you logged-in as root or are you working in a root shell ( using su
or sudo)? Depending on your security settings X-windows may not permit a
program that is run from a root shell to access the display, which
belongs to the user logged-in through X-windows.
I get around the administrator access issue by installing CCP4, and all
other non-OS software, with non-root ownership, a non-root administrator
account, which shares the environment with all other users. For one
thing, I do not want to source the multitude of /etc/csh.cshrc and
.bashrc files as root. I am sure that others have different, and
probably more elegant, solutions to this problem.
PS. It also seems that the TCL/TK environment is not set in the root
shell you are using.
Good luck,
Mark

Fellow users,
I just installed v6.1.2 on Ubuntu 9.0.4 today and have run
into the following problem when I try to run ccp4i for the
first time as root to configure the program:
r...@########:/home/########/Documents# ccp4i
No protocol specified
Application initialization failed: couldn't connect to
display ":0.0"
Error in startup script: can't read "tk_version": no such
variable
while executing
"catch "set system(TK_VERSION) $tk_version""
(file "/usr/local/ccp4/ccp4-6.1.2/ccp4i/bin/ccp4i.tcl"
line 1)
(file "/usr/local/ccp4/ccp4-6.1.2//bin/ccp4i" line 1)
The odd thing is that I can launch ccp4i just fine as a
regular user, but then of course I get the message about the
first time ccp4i has been run and the need to configure it,
which requires administrator level access.
Anyone have any ideas?
Thanks,
Stuart Endo-Streeter
