Thanks a bunch Haku!. I wished everybody was as descriptive as you were

. Well, you've got quite some problem there

. Try some or all of these:
1 - When you boot up linux and X tries to start, but fails, let it fail. When that happens press and hold CTRL + ALT + F[1-6], that means press any F key between 1 and 6. You will be in a terminal. You can return to X server anytime by pressing CTRL + ALT + F7(won't work for you now, but remember that). Now, try running:
xf86config
and answering the questions correctly. When done, try typing startx and see if works. It if fails(try it again bunch of times with different options first), then:
2 - edit the file located at:
/etc/X11/XF86Config
manually (depending on your distribution, it could also be XF86Config-4). Scroll down until you find:
Quote:
Section "Device"
Identifier "device1"
VendorName "nVidia Corporation"
BoardName "NVIDIA GeForce4 (generic)"
Driver "nv"
Option "DPMS"
|
Your drive may be different, depending how Linux had probed it. You could try to play with another driver, as vga, instead of nv. Change also the resolutions and refresh rate in there. Be always conservative. You can damage your monitor there if you don't know what you doing.
Either editing XF86Config or running xf86config, try using very low values for everything, like an ordinary screen resolution and dept color and keep trying to re-run startx when you're done editing. If still no go:
3 - Hopefully you've installed a text based browser and your network is working. If your network is working, but you did not install any text based browser, do it now(Mandrake):
urpmi lynx
you will be prompted for one your your Mandrake CD's. There should not be any problems, unless you are having a really bad day

. Now, fire up lynx and go to nvidia.com
lynx
www.nvidia.com
and grab a driver there. Don't get the latest one, it's always buggy. Get 44xx if you can find. Otherwise grab 55xx. Download it and install the driver:
sh NVIDIA-Linux-x86-1.0-xxxx-pkg1.run
Now, edit the file /etc/X11/XF86Config-4 again manually, and replace the marked line:
Quote:
Section "Device"
Identifier "device1"
VendorName "nVidia Corporation"
BoardName "NVIDIA GeForce4 (generic)"
Driver "nv"
Option "DPMS"
|
to:
Driver "nvidia"
be careful with upper/lower cases, Linux is a case sensitive OS

. By now, you should have nvidia drivers installed and running. Cross your fingers and type startx (can you really type startx with your fingers crossed?lol).
If you network is not working with Linux, hopefully you are dual-booting and can grab nvidia drivers from Windows, boot into Linux and install it as described above. It'll do just as well.
If all else fails, I've no more cards to play and I will have to leave you at LQ experienced members
Good luck mate!
P.S: keep always in mind to, when running xf86config, to keep as accurate and conservative as possible. A bad configured mouse can crash the X server, a high resolution with generic drivers won't be good. Wrong refresh rate can even be dangerous for the monitor. Start with something like 800x600x16 and try to initialize the server. If it crashes, keep going lower and lower.
Good luck once again!
