DISPLAY PROBLEM

Nobody's Hero — Thu, 29 May 2003 13:54:40 GMT

This is a basic problem that I can't figure out.

I set my DISPLAY variable for my display, however this Nclass running 11.0 won't open with this display setting. Ok on all other systems. What could be causing this? This is a basic command executed on many systems many times per day. No problem on other systems?
When trying to run the sam or PV or GPM, I only get character base, not GUI.

I get error:

pv
Error: Can't open display: 10.31.1.106:0
Error: Couldn't find per display information

Is CDE running?

tail -n 20 /etc/rc.log

Starting the Apache subsystem
Output from "/sbin/rc3.d/S825apache start":

Doesn't DISPLAY need to be 10.31.1.106:0.0 ?

Nope, should have tried that one first!

yes CDE is running I believe. rc.log claims it has started. How can I verify 4 sure?

ps -ef |grep dtlogin will tell you if CDE is started.

10.31.1.106 is the ip of the N-class right ?

so does the N-class or 10.31.1.106 have a graphics card installed ? or is it a pc using Xmulation to provide a graphics device to the Xserver remotely from the N-class ?

Hi Robert,

Can your N-class system resolve the 10.31.1.106 IP address correctly? Does it have a valid route to that IP?

Robert,

Does this only happen for root or any user?

this happens to any user, not only root.

Robert,

What happens on your N-class box when you do this?

nslookup 10.31.1.106

John
what command can I use to see if the Nclass can resolve my ip address...traceroute????

Thsi is causing us some real problems....

John,
nslookup see's my workstation from DNS OK.
I can't figure this one out.

Re: DISPLAY PROBLEM

John Poff — Thu, 29 May 2003 14:22:38 GMT

Robert,

Ok, now try it the other way. From your W2k box try running nslookup [try getting to a DOS prompt] and see if it can resolve the IP address of your N-class box. If so, try it again with the hostname and then the fully qualified domain name of the n-class box. All that stuff has to work for your X machinery to be happy.

yes John,

I just tried all ways. w2k sees the N just fine. Im stumped. I may open a call with HP.
Unless you have any other ideas....

John, sorry. you were right. I cant ping or telnet from my workstation to the HP9 machine.
I think we have a vlan problem on this 10.31 network. I have an alternate lan card assignment with a 10.31 address. This was causing some problems on some other systems as well. I need to remove the alternate 10.31 ip assignment from the N. Thanks for helping me work through this.

The only other thing I've seen before is when the HP box has a problem with the hostname. When you do the 'hostname' command on the N box, does it give you the correct name? If so, does 'nslookup ' give the correct IP address for the N-class box? I had a situation once where a box got a mismatch between the hostname and its IP address and the X stuff just wouldn't work.
