Quick question

This is the 3rd Centos 6.2 server doing it.

We plug the server in to a big 47" screen we have mounted against the wall to do the clinet server installation. All done a working and ship it

Then on the client side, a normal 15" monitor is plugged into the server inside the rack, and there is no display ?

I am guessing it still has the display settings saved for our big monitor.

WHat command can I run to pick up the new monitor or refresh the display etc ?

Thanks in advance ( I have never seen this before )

I believe that X logs would help because X should complain something about not being able to find a monitor and hence not showing anything.

Hi There

IT is not an X server, it is running on runlevel 3

ANy more ideas ?

Hard to diagnose this kind of problem remotely. Although it sounds like hardware problems.
You said 3 different machines. So some questions.
- Are the machines send to the same customer or different ones.
- Do you use the standard vga interface (embedded or card).
- Does the customer have no text at all or only during boot.
- Have you tried a standard lcd yourself on the server.

Hi there ! Thanks for trying to help

1.) Sent to different customers
2.) I use the standard onboard vga connection, vga cable to big screen
3.) No text at all
4.) Yes, standard lcd small monitor, and nothing

I am so doubtfull that we will have 3 out of 6 servers now with "faulty" vga ??
I guess the only test is to bring one back all the way and plug it into our setup screen here in the office.

It makes no sense, I know

If the PC shows sweet nothing from switch on, then it tells me it is vga related, because once you have waited 3 minutes or so for the server to boot, I can log into it remote, and all fine, it is just when you stand infront of it and try to work on the actual server, there is no display.

You mean nothing like no problem or no screen.

If they worked when you configured them, I hardly think they're faulty.

You could check if the client uses a KVM switch. Have seen some strange behavior in the past with those.

Hi there

I meant no display, not working yes.

We used kvm switch in one location yes, not in the other two locations, will just verify that as well.
