X woes - can't set the correct resolution no matter what...

[Valent Turkovic]

Hi.

I have Fedora Core 6 and by default it choose i810 driver for X for my
Intel 915 chip. 
With i810 driver I had no problem using only my laptop screen - but when
I connected external 19" screen all hell broke loose :) to be a bit
poetic. or more to the point:

In my comment #8 you can see that I changed to intel driver, but even
that still doesn't work like I expect.

I need my external monitor running at it's full resolution of
1280x1024 and desktop also at that resolution. I got desktop running
with 1280x1024 but only on a 1024x768 screen resolution - I didn't
know that that was even possible! So my deskop acts as with beryl with
zoom plugin - I can see only portion on the desktop and the desktop
pans as I move my mouse from one corner to the other.

I was feeling lucky and tried setting up dual screen setup via
system-config-display - that turned to be a big mistake. I got config
that wouldn't even work everytime. I got 2 video cards configured -
one with intel and other with vesa driver ?!?

So please give me your insight on how to make X behave properly, just
dont rtfm me, thank you. Del.icio.us links, url's, blogs and any other
piece of info is greatly appreciated.

Do you have some concrete info regarding fc6+X+intel driver ?

I'll post any info you need about my hardware, logs, etc... just ask.

Thank you in advance,
Valent.
