DISPLAY problem

Hi guys!!

Here's what may be a mult-threaded problem, but I'll start here. We have an Oracle implementation to take care of. I am setting up an rx7640 as the db server, and when I try to set the display for Xterm, I get:

# DISPLAY=10.128.11.1:0.0 ; export DISPLAY
# xclock
Error: Can't open display: 10.128.11.1:0.0
Error: Couldn't find per display information

Is there something I'm missing? This is just a small local network at 1st, and when it's setup, we'll take it onsite.

If you need any more information, please let me know.

You need to do
xhost +

in server 10.128.11.1

No luck:

# xhost +
xhost: unable to open display "10.128.11.1:0.0"

Re: DISPLAY problem

So, are you sure on server, check it with;
# getip `hostname`

indicates the correct IP ?

Re: DISPLAY problem

ok try this,
# whoami
and
# who am i

if they are different, you have to use logon userid to xhost , try this:

Ctrl + D
xhost +

This error message indicates the X application has failed to connect to the display.

Does the rx7640 have a graphics card and a display installed?

Let's start from the screen on which you would like to see the Xterm and other output. What's the computer it's plugged into? (Is it the rx7640 server, or e.g. your Windows workstation?)

What is the IP address of the computer that is connected to the screen you want to use? Is it 10.128.11.1 or something else?

Is that computer running an X11 server program of some sort? (On Windows workstations, this would be a commercial product like ReflectionX, or a free one like Xming.)

If you're logged on locally to the rx7640 server using the graphic CDE desktop, the DISPLAY value should be already set for you (probably to ":0.0"); don't mess with it in that case.

Re: DISPLAY problem

Also, from the workstation, you need to 'Enable X11 forwarding".
