It's either the video card driver (most likely) or the monitor (next-to-most-likely).

You'll probably need to boot to Runlevel 3 (text mode) to fix the problem.

To do this, reboot the computer (reset it manually if you have to).

At the GRUB bootloader screen highlight the kernel you wish to boot from using your up/ down arrow keys and type the letter e.

This will place you in edit mode

Scroll down to the kernel line and press "e" again.....your cursor will be at the end of the kernel the spacebar and type in the number 3

Hit enter

Then press "b" to boot.

You should be able to boot into text mode now.

Login as root.

Type the following command:


The display configuration window appears.

Click the Advanced'll see a section for monitor configuration and video card configuration. Select video card configuration.

In the list of video adapters look for VESA and select it. Click OK and exit out of the configuration tool.

Reboot. You should be able to boot into graphical mode with the generic Vesa driver. If you can do that, then I recommend getting Nvidia's driver from and installing that.

If you can't get the redhat-config-xfree86 menu to come up, let me know.

If you get the black screen again, then boot back into runlevel 3 like you did before.

login as root

Open the /etc/X11/XF86Config file with the following command:

vi /etc/X11/XF86Config

scroll down until you see the section called "Device"

press i to enter insert mode...edit the "Device" Section so it looks something like this:

Identifier "Videocard0"
Driver "vesa"
VendorName "Videocard vendor"
BoardName "VESA driver (generic)"
VideoRam 8192

The video ram section on your adapter may be different than what is above.

When you are finished typing, press the Esc key then type the following to save the file and exit the vi editor:


Once that is done, try starting x with startx.

Hopefully that will get you to where X will start without killing the monitor.....keep in mind that if this works you are running with the generic VESA driver, not your Nvidia one. If you want to take full advantage of the Nvidia card, I suggest downloading Nvidia's drivers.
