Unhappy trouble shooting the GUI


I am a new user of scientific linux 6 .
I am working on a project started by others and Unfortunatly , the GUI stopped working.
I need to find out how to trouble shoot the GUI to solve the problem .
What I have now When I open my PC is a complete black terminal .
I need to go back to the GUI and start troubleshooting.
Can somebody advice me how to start ?
Thanks

Welcome to Linux Questions!

Did you do any update resulting in this problem?

You may try reinstalling GUI packages.

Does Xorg starts? Can you atleast login in a VT (Virtual Terminal)?

Hope you can help

What graphics card/chip you have? Post the output of 'lspci' here.

Post the ouput of command 'ls /usr/lib/xorg/modules/drivers' here.

Can you run 'startx'? If it starts then it would produce a log. Post this log.

Give the exact output, when 'Xorg -configure' was run. See your current directory to see a file named 'xorg.conf.new' produced. Check it.

And post for all answer/steps listed here.

I am not familiar with this distro but I do have some experience with Redhat/Fedora and rpm.

It appears the xorg drivers for graphics and may be other hardware is missing.

Please post the output of:

Code:
rpm -qa | grep xorg
Do some research on xorg graphics and input drivers.

So the problem is you don't have xorg driver for

1) Intel chip you have as VGA.

2) Input driver for keyboards and mouse.

So install those xorg drivers from your installation cd/dvd disc or a repository. Note all drivers package start with 'xorg-'.

Well, with a VGA only chipset, most of the more recent GUI (Gnome, Cinnamon, and maybe even Mate) will not work. They are using GL capable hardware acceleration, which is not available with VGA only.

Might have to try something simpler like LXDE or Xfce.

But the GUI was working well at first .. Why did it stop now ?
How can I install these xorg drives from a repository ?
What shall I do certainly ? What command lines can be used for the installation ?

Many thanks for your help

Frequently, you would have to install them from the distribution first.

Since SL is based on RH, they should be in the repository (package groups like "LXDE Desktop", "Xfce Desktop" - note, I'm working from a Fedora release, so you have to check the list of desktops in the repository - "yum group list" should list all the available package groups including the desktops)

Then install it by 'yum groupinstall "<chosen group>"'.

Normally, this should be sufficient. Sometimes the GUI login isn't included causing issues, but I think that has been a packaging error. At a minimum, the old standby xdm can be used (should be in the package xorg-x11-xdm).
