Black Screen after Boot
 
I recently installed Red Hat 8.0, and the install went fine (apart from a problem with the Grub bootloader, so I had to do a re-install and choose Lilo instead. Which works fine)

The problem is that Linux boots, but when it finishes and is about to go to the graphical login, I just get a black screen.

I had the same problem when I tried to use the graphical installer as well. I did try to get the graphical install working by trying 'linux lowres', 'linux resolution=800x600', etc, but none worked.

How can I fix this?

do you have more than one video card? ie - one onboard and one agp/pci? you would need to specify which one to use during the install, also check to make sure the sync rates of your monitor are correct.

I have onboard graphics only.

Im using the ASUS A7N266-VM motherboard, which has onboard GeForce 2 graphics.

Any suggestions?

Just questions ... does the box die then?
Or can you get to a text console by
pressing Ctrl-Alt-F1 (or 2,3,4... :})?



Cheers,

try ctrl-alt_(f1 f2 )
then at the prompt login and try "startx"
or "Xconfigurator"( i am not sure abt. the correct command of Xconfigurator, i think this the one with X in caps)

Oaky, thanks.

I will give it a try.

I tried pressing Ctrl-Alt-F1 (F2, F3 and F4) when I got the black screen. But I didn't get anything.

I can press Ctrl-X at startup to get to a prompt saying 'boot:', but the only command that works there is 'Linux', which boots linux.

1) Add " 3" to your kernel arguments then when you boot you should be in CLI mode.
2) Login as root
3) Run "redhat-config-xfree86" to configure your hardware
4) Test your settings by running "Xtest", you will get a message on your screen asking if it has worked. If it hasn' then just leave it for 15 seconds and it will exit automatically. You can then go back to step 3 and reconfigure your hardware.

Thanks, but I am a bit of a Linux newbie. :) Sorry.

How do I add " 3" to my kernel arguments?

Will I need to boot into rescue mode to do this? and what is the command to do it?

I do get the last few bits though!

At the bootloader stage there should be an option to edit the proccess. You press "e" in grub - I'm not sure about LILO. Then look for the line starting with kernel and add " 3" (no quotes) to the end of that line.

HitmanIP7 05-14-2003 04:40 PM

Okay, I will give it a try.

I have the same motherboard as you and I do not have this problem (I use Mandrake 9.1)

Have you downloaded and installed the nVidia driver?

Also: I did have a problem with my on-board graphics due to a timing problem. If you have Windows, can you use Win to put your monitor into the desired resolution, then press the button(s) on the front of your monitor to find out the Vertical Refresh and Horizontal Sync.

Then as root, edit your XF86Config-4 file (if it is not there, use XF86Config), and ensure that the range given in the lines VSync and HSync or similar cover your monitor's timings. I did this and my picture went from a complete disaster (so much shaking it was impossible to read normal text) to solid.

I haven't downloaded the nVidia driver.

Thanks for the info, but I dont have Windows on the machine, only Linux, so I cant do what you said. If I get the same problem as you though, then at least I know what to try.

I dont know the option to edit the proccess in LILO, or the key to press. I have looked around, and searched on Google, but I cant seem to find what it is.
