Limited Screen Resolution Options
 

Hi everybody I just recently installed Fedora 7 (i386 on an AMD X2) and I have been unable to properly configure my display. Fedora properly recognizes my display in the control panel:

Monitor Type: Dell 2007FP (Digital)


and I think it is recognizing my graphics card:

Video Card: ATI Technologies Inc [Radeon X1300/X1550 Serries]
(Secondary)

but when I try to change the screen resolution in the pull down menu I am limited to 1280x1024 when I know I should be able to display 1600x1200. As a result everything seems comically large!

I am relatively new to linux and could really use a hand!
Thanks for the help!

My Dell 17" LCD has a Max resolution of 1280x1024.. are you SURE yours supports a higher resolution ?

the refresh rate settings for my screen is pretty much identical to yous.. you might want to check the specs again..

Thanks for the quick reply!
Yeah I am positive it is capable of higher resolutions. It is natively 1600x1200 @ 60 Hz and it was operating like that using xp. Any other ideas?

I just checked the specs and you are right 1600x1200 @ 60 with the refresh rates you have entered..

how very odd..

Might want to try one of the 'modeline' generator tools..

Try adding the line to your Screen->Display subsection.

If above (camh) is not enough, you can add option "UseEdid" "false" to the device section as well.

Well I added the the resolution to the modes section but that didn't change the available resolutions on the gui pull down menu. Here is my modification with the UseEdid althought that didnt seem to fix things either:

Section "Device"
Identifier "Videocard0"
Driver "vesa"
Option "UseEDID" "False"
EndSection

I am wondering if it not specifically recognizing my video card in the xorg.conf has anything to do with it. Thanks for all the help!

Oops, overlooked that :study: Forget all other remarks and install the driver first.

I didn't realize there was a driver. I was of the understanding ati drivers for Fedora 7 did not exist. Is there an open source driver I could use thats not part of the fedora 7 install that would work? I am totally lost on this one.

well theres the opensource driver 'ati' or you could download and install the proprietary ati Drivers 'fglrx'
