I just installed the Mandiva 2006 on my second computer and after I installed it and it reboots it goes to the following:
Mandriva Linux release 2006.0 (offical) for i586
Kernal 2.46 on a i686/tty1
localhost login:
after I type in my login and my password I get:
{rkvideo@localhost ~}$

Looks like it's defaulting to a non-gui run level. In other words there are 2 steps to be completed before you can use your gui from system startup. Firstly, you need to configure the gui to recognise your hardware and secondly you can modify your /etc/inittab file to select a gui run level on boot.

As far as configuring your gui goes, what happens when you type startx after you login? If you get to a gui, you can skip this step unless there are performance problems with the display. If there's no gui, you'll need to modify the config file (/etc/X11/xorg.conf) for the gui. To do this, try running one of the following (as root) xorgcfg, xorgconfig or xorgsetup. From memory, xorgcfg has a gui, and the other 2 are text based. Once you've run these tools, try startx again. This process may take a few iterations - there is the keyboard, mouse, monitor and video card to get working.

To get the gui happening from startup, modify /etc/inittab - there is a line in there that says id:3:initdefault:, for Mandriva it should probably be id:5:initdefault: (on Slackware it's id:4:initdefault:).

Hopefully that's all there is to it.

I tried the above when I run xorgcfg I get gfatal server error. My internet is not connect to the computer

when i tried xorgconfig iget smae message after rerunning startx

Did xorgsetup probe for your hardware? What can sometimes work is to use one of the sample config files in /etc/X11 by copying (for example) /etc/X11/xorg.conf.vesa to /etc/X11/xorg.conf and trying startx. The file usually needs to be modified but it can be a useful starting point.
