fedora core 5

I know most of the post here are about windows. But I haven't found a cure so heres my problem. I've recently installed fedora core 5 on a backup machine so i can get into web servers and mail servers. But when i changed the resolution setting in admin display from 800x640 to 1024x768. the screen went blank and now the computer will load but at the point where I'm guessing the display settings are loaded it goes blank and you cant see anything. any help would be wonderfully.

 

You probably chose a setting your monitor cannot display (probably an invalid refresh rate). Press ctrl+alt+minus, wait a few seconds and see if an image shows. If not repeat the procedure until an image does appear. If after ten tries you still haven't got an image, try the ctrl+alt+plus method in the same way.
If the above fails, try ctrl+alt+backspace to kill the Xserver. You should see a console now.
Report back, so i can explain what to do next.

 

All-write ctr+alt+plus got it back up. is there now anything i need to do so it doesn't happen again, i now the monitor is a gateway 2000 crystal scan and it will Handel 1024x768 at 75hz but i think I'll wait till you get back to me. ho bye the way thanks not even the guys at fedoraforums came up with this. but thats not to say they don't now what there talking about. because if i did then i wouldn't be begging for help.

 

It shouldn't happen again, unless you change your resolution again.
X chooses its display settings from a couple of so-called 'modelines' in your xorg.conf file. If it decides to use one your monitor can't handle, you get a corrupt/black screen. Ctrl+alt+minus or ctrl+alt+plus forces X to use a different modeline, which your monitor can handle (not guaranteed).
If you know exactly what your monitor can handle, you can calculate your own modeline for optimal settings. You then have to insert the new modeline in xorg.conf and select it by further editing xorg.conf or using those key combinations. If you want to add your own modeline, let me know. I'll post exact instructions then

 

OK for some reason my last two post didn't show up. but yes i would like the instruction for xorg.config also thanks again.
