Long story, using a KVM switch, wanted to offset my video card output and so I made some changes to XF86Config.
After initial boot (from the login screen onwards) my video card output is beyond the range of my monitor. (Yep, I know that I am stoooopid!)
I'm running RH8.0 and am about to leave the realms of newbie but this one is defeating me. How can I boot to a command line?
Whilst I will build RH on another drive this weekend to access the old if necessary, can anyone tell me how to get into a full shell in order to change XF86Config back? RH8 only seems to give me a reduced shell (in recovery mode) with very few commands.
Unfortunately RH8 defaulted to GRUB as a boot loader which doesn't give me an option to add a switch. There appears to be only full boot or rescue mode.
(I used to use SuSe with LILO. Oh how I wish I had left it alone.....)
After the boot change to the second virtual terminal with <Ctrl><Alt><F2>, login as root and issue the command 'telinit 3', this will sent the box to runlevel 3 (multiuser without x), from there you can edit your X config.
I would advise that you set the runlevel to 3 when you intend to play with your X server settings, you can do this by editing /etc/inittab and changing the default runlevel, you can then login to a text console and do 'startx' to start x, if something goes wrong you will be dumped back at the text console where you can tweak the config untill it works.
