monitor lock out
 

When playing with my monitor settings, I set it to 1280X1028 and now it says' CAN NOT DISPLAY THIS SETTING. I'm very new linux and get stuck at grub on boot. I have fedora 2 core2.4. dell e152fpb flat panel. How do I reset it? Thanks for any help.

If you can somehow get into the file "/etc/X11/XF86Config" and edit it (you will need
to be root to do that), you can change the monitor section back to the resolution that
works. Here's how the section reads in mine, for a 19-inch monitor at 1280x1024 resolution:

If when you boot you get a choice of something like "press F1 for other options" you
can do that and chances are you may be able to go

su
<enter password>
cd /etc/X11
cp ./XF86.config XF86.config_bkp
vi ./XF86.config

or it might be "vim" for the editor--your system will surely have one or both.

Then press "insert" or "i" to enter editing mode and edit that section,
and when you have it the way you hope will work, press

esc
:
w
q

which will write the file and quit the editor. Then try booting and see
if this change did the trick. You can always restore the file from the
backup copy you made if need be.

I can't get to root from grub, can I? I can see /etc/X11/XF86Config" with knopp but can't write.

Hmm. I would think there's a way when you very first start to boot, to intervene and be able to change things.

I use Mandrake, not Fedora, so I don't have a way to test. With Mandrake, you are given a choice of pressing "Enter"
or "F1" depending on whether you want to boot normally or hold up booting to make changes or troubleshoot.

If this isn't the case with your normal boot process, could you boot from the first of your installation CD-ROM's
and be able to use F1 (or whatever other key suggested) to get into the system?

Can another Fedora user here help out?

I tried to fix with cd1 repair option from fedora but was told I have no partition's? But all is visible with knopp. how can a monitor settings change my partitions?
