Boot to command prompt directly


Hello,
I am trying out Red Hat Linux 9.0 (first venture into the Linux world). I got it working, but tried to modify the display settings (to increase the color settings to 24Bit true color). I got a message saying that my old settings were backed up as <filename>.bak (I don't recall the filename). When I rebooted, I found my display totally messed up... the screen is black and I can faintly see the characters written on the screen - none of them are legible though.

I think I will be able to restore the old configuration file, but I don't know how to boot directly into the command prompt - I tried booting using the boot diskette, but it still takes me to GRUB GUI and again, I can't read anything there...
Is there any way for me to bypass the GUI and go directly to the command prompt?

Please help!
Thanks
- Joseph

Hi,

As for the file which was backed up, it was probably /usr/X11R6/lib/X11/XF86Config. I don't know why the problem occurs even when you boot from a boot diskette; X wouldn't have started by the time you get the GRUB screen. Maybe you can try knoppix. Did you try pressing Ctrl-Alt-F1 after booting? What happened?

Thanks for your quick response Arvindn,
There apaprently was some problem with my boot diskette - I asked a friend for one and when I boot using that, I get a command prompt for GRUB. But it is not in the kernel - how do I go from the GRUB command prompt to the kernel prompt? normal unix commands like LS are not working at that prompt...
Any suggestions?
Thanks again!

When you say "kernel prompt" you mean bash prompt or shell prompt, because the kernel doesn't interact directly with the user :-)

Try typing "linux single" into the grub prompt.

Sorry - I meant shell prompt (I'm really new to Linux/Unix, so I'm not too familier with the terminology... )

I will try Linux Single at the grub prompt today and hopefully be able to restore that config file... I will let you know this evening about how it turned out...
Thanks again!! I really appreciate your help!
