[SOLVED] Can't go above 1024x768

1349 · 03-03-2010, 07:42 PM

I'm using a 6200AGP and I'm having quite a problem fixing my xorg.conf files to make it so I can go beyond 1024x768. A friend of mine is trying his best to help but it got both of us baffle at why it's not working the way it should.

Below I present you fine gentlemen my Xorg.0.log and my xorg.conf. We have spent many hours trying out many different xorg.confs that end up in failure. This current one is the only one that allows to be started up at a sorta decent resolution of 1024x768. The default nvidia xorg.conf won't let me go above 640x480.

You're missing a quote after

Code:

Option "UseEDID" "FALSE

I'm not sure how xorg would interpret that, but that's the first thing that jumped out at me. Did you add that to try to force it to use something besides 1024x768? If not, try commenting that line out and see if your monitor will report higher resolution capabilities to the graphics card. If that didn't work already, you might have something wrong with your monitor.

Edit:
I took a closer look at your Xorg.0.log and it appears that the missing closing quote doesn't cause a problem. Xorg is parsing the option correctly without it. Same advice applies though - try commenting that line out to see if your monitor can provide the correct resolution information on its own.

That didn't fix it. Nothing is wrong with my monitor. I can set my monitor to very high resolutions on Windows with it's Nvidia drivers. Only Slackware had problems with this stuff.

Can you post another Xorg.0.log after removing the `Option "UseEDID" "FALSE"'? I'm curious what your monitor reports as valid modes.

Other thoughts - on Slackware 13, I can start my ATI card with the "radeon" driver with an empty xorg.conf. You don't specify Slackware version or nvidia driver versions - those might be useful to know. The empty xorg.conf may not work with the nvidia binary driver though. I can't test it - I'm using the nvidia driver on an older machine running Slackware 12.1. As far as I know I have to have an xorg.conf for this setup. I don't have anything in the monitor section other than an identifier though. No refresh rates or modelines are necessary.

How old is your monitor? Is it CRT or LCD?

CRT and using latest nvidia drivers so I guess they are 190.53. Hold on and I'll post another log. Testing some other things out

Hold on. Now its barely working at all. This is some stupid stuff right here.

I think the relevant section is:

Code:

I should've been more specific about "something wrong with your monitor". I was thinking along the lines that its EDID either isn't working correctly or the monitor's so old it doesn't have one. Try dropping back to the vesa driver to see if it can read the EDID correctly. You may just have a monitor that doesn't cooperate well with the nvidia binary driver.

The Linux graphics stack has been fairly messy lately ("lately" being since about 2008), and the binary drivers from Nvidia and ATI are a crap shoot with what xorg/mesa/drm/kernel/video hardware combination you have. The ATI driver is more sensitive to that, but you might be seeing it with the nvidia driver here. If you can find an older nvidia driver that might also be worth trying.

Are there performance hits with using older drivers? I might try this out then.

This conf fixed it all. Posting this for future people searching these forums.
