X windows not working right (no windows or graphics display, only back

[tringuyen84]

I have been using Linux for about two weeks. I installed Red Hat Enterprise Linux WS (v. 4.0 for x86). Every thing has been great until now.

What’s wrong:
Previously Redhat would display a graphical status bar and then take me to the graphical login screen. Now I get no graphical any thing (status bar login screen, no windows of any kind). When the normal login screen would appear all I get is a blue screen. This is the normal background for my login.

What can I do to get it to work again.

So when it is done booting, are you at a console login, or at a "blue screen" where you can't log in, or what?

Did you install anything in these two weeks, or muck with the bootloader config file (/etc/grub.conf)?

If you can log in, show the contents of this command:

cat /proc/cmdline

I'm not sure if that fade-in bar is provided by the rhgb package or what, but try this command, to check on the status of that package:

rpm -qV rhgb

How did you shut down the system just before this problem occurred?

[tringuyen84]

I used command rpm -qV rhgb, i looked at the status of that package no problem.
can I recofigure Xorg.conf?

[tringuyen84]

I used shutdown command in console to shut down the system.

Have you tried using

system-config-display

Or, if you are unable to install that package:

Xorg :1 -configure

That should create the file /root/xorg.conf.new (a default xorg file), which you can copy to /etc/X11/xorg.conf.

Then you can make all needed changes.

Hope that helps.

Also, show the contents of these files:

/etc/grub.conf (or /boot/grub/grub.conf if the other is not found)

/etc/inittab

The first will tell what kernel arguments are passed at boot time (as will the 'cat /proc/cmdline' command I suggested earlier), and the second will tell your default runlevel (for RH, 3 = text-only/console and 5 = GUI).

Now, I have a problem following:

I used SSh shell to connect server.
After I used system-config-display command, then display screen was:
[root@oracle ~]# system-config-display
Trying with card: ATI ES1

How will i do next?

[atreyu]

Are you still trying to configure X/GUI on this box? If so, in order to do that you should be directly connected to it (Monitor and keyboard, etc.) and not by remotely logging in (via ssh or whatever).

The system-config-display command is only useful once you have a partially working X windows environment up. You'd be better off with the "X -configure" command, which will create your initial xorg.conf file.

[tringuyen84]

When I try using "X -configure" command, the display screen is:

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

So, what i do next?
