Hi all,
i have a question about DTU display variable.
normally when i login to the sunray server through DTU
and i can get the display name like ":3.0" from "echo $DISPLAY"
however I'd like to change to "hostname:3.0".
does anyone has an idea about it ??
It's relatively simple to do this, but why do you want to if I may ask?
Using :NN as your display number uses various optimized IPC
mechanisms which will give better performance than using
hostname:NN (e.g. shared memory versus socket/tcp/ip).
Are you using CAM/Kiosk mode or are you using a normal
Solaris/Linux login? The approach would be different for each.
In all cases you'd want a ksh stanza something like:
------- BEGIN STANZA ------------
if [ ":${DISPLAY#*:}" = "$DISPLAY" ]; then
DISPLAY=$(hostname)$DISPLAY
fi
------- END STANZA --------------
The question is where to put it? If you have a
standard Solaris login, then I'd put it into
$HOME/.dtprofile
This should work for Kiosk mode in Solaris SRSS
4.0 also.
For Linux I'd suggest putting it into $HOME/.login
if you use bash for your login shell, but other
people may have better suggestions. If you use
csh or tcsh for your login shell this won't work
because you'd need csh syntax and there's nothing
in csh quite like what I showed above. There are
obviously alternatives using sed or similar,
however.
However for pre-4.0 CAM mode you'll have to modify
an SRSS CAM startup script I'm afraid, and that's
subject to clobbering with a patch or SRSS upgrade
so you'd have to reapply it. Let us know if you
want to go this route and I'll send you
instructions later when I have access to a CAM
system I can poke around on (I'm downloading some
CentOS 5 DVDs at the moment (which should be
welcome news for many of you :-), so can't bring
my VPN tunnel up to Sun right now).
