Corrupted display when booting without external monitor

[Martijn Bronkhorst]

Dear Mailinglist,

I have installed Fedora Core 2 and when I boot, I get my screen all 'torn
apart'. Fedora correctly recognized my videocard (ATI mobility 128mb) and I
have manually selected my display (Dell 104 x 768 Laptop LCD).

The funny thing is, when there is an external monitor connected and you
press the FN key to select to output on both displays .. The screen is
perfect on the laptop. When I boot without an external monitor connected,
the screen is unreadable again.

Can you advise me on what to do, where to look ????

Thnx.

Check the specs for your monitor, then go to:

http://koala.ilog.fr/cgi-bin/nph-colas-modelines

It will generate a modline for your xorg.conf (guessing that you're 
running FC2)

If you don't know what xorg.conf is and what to do with it, google for 
it for a while, and then ask here :)

actually

http://xtiming.sourceforge.net/cgi-bin/xtiming.pl

seems even more useful if you want to drain the last few Hz from your 
monitor :)
