Higer Video Resolutions in Linux

[Speedy]

Hi all,

I just started using Linux again about a week and a half ago. So far I love that its so much faster than Windoze and I'm able to get pretty much everything running except WINE, which is a PITA. Anyways, I've got it set up with Dual Monitors, which was super easy to set up. However, I've got it running in 2048x768

I would like to run it in 2560x1024, which is what I was running in Windoze, however, I don't see that option and when I run in anything higher than 2048x768, I have to move my mouse up to the top or bottom of the screen to see the whole screen.

I'm running OpenSuse 10.2. I've got dual 19" Viewsonic Optiquest Q9 monitors and a Sapphire ATI Radeon X800pro video card. Is there any way to get the screen resolution I am looking for?

Thanks :)

The most effective way to change your resolution is to edit the file /etc/X11/xorg.conf. If you don't mind, open that file in a text editor, and post the complete content here.

Depth is how many colors -- Surely you are familiar with 24 bit color in windows? That's Depth 24 :)

At any rate - Here's my section


Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024"
EndSubSection

That gives me 1280x1024 @ 24 bit color :)

Enjoy

Hmm, I added it in and I still wasn't able to change it.

[leroys1000]

The section "modes" shows what the monitor is
capable as detected by linux.
It won't run at anything that is not in the list
So it looks like you might have to add "2560X800"
to the beginning of eack line in the sceen section
so you have it available for each bit depth.
If it is working,you should be able to change resolution
in the video controls.

[Speedy]

I was messing around with everything and I killed Linux. Oops. Anyways, I'm back at square one again. Do you think if I installed the ATI driver it might give me some higher res. options?

Suse hardware detector (SaX) is not correctly identifying your monitor(s). It thinks it's only capable of 1024x768 so is giving you the max it thinks it can.
I had similar issues with SaX not detecting my Phillips 109s 19"CRT.

Before you can safely run higher, you have to convince the X-server that the monitor can handle it.

Google your monitor make and exact model and see if you can find it's specs - particularly the vertical and horizontal refresh & sync modes supported and change that - either in your xorg.conf file or using the SaX GUI.

[Speedy]

Oooh, so that's the section I was supposed to look at. I think I actually have the original instruction manual for it, so I'm assuming it would probably be in there as well. Thanks, I'll report back with my results.

[Speedy]

So these are the specs, I'm kind of confused. Based off this link I should set my settings for what?

Will I have to change anything to make this work for the second monitor

[leroys1000]

You will need to install the ATI or fglrx driver to get out of vesa mode.
