Why are xorg.conf modes being ignored?

asdflol · 08-22-2007, 02:06 PM

I'm trying to get into the resolution 1440x900@75, and linux just wont do it. For some reason, it's running in a virtual window, and the virtual resolution is 1152x864. I don't know what the physical window's resolution is at though.

My monitor is an LG194WT, native resolution is 1440x900, it supports it's native resolution at 75hz. Horizontal: 30-83, Vertical: 56-75.

My video card is a nVidia Riva TNT2 with 32MB onboard ram.

I installed NVIDIA-Linux-x86-1.0-7185-pkg1 for my drivers (and I do see the logo when starting up).

This slackware install is pretty new, I installed dropline gnome after installing.

Drumroll, please...

I want to get rid of the virtual window completely and use my native resolution, I'm completely clueless.

I haven't check the specs but have you checked to see if you card can handle the widescreen aspect ratio. I have give or take the same card in my work machine and wide screen was not on viable solution at that resolution.

asdflol · 08-22-2007, 02:46 PM

I'm pretty sure it does. I've looked online and I've seen people talking about using this card on their 1600x1050(something like that) monitors. I could try to swap this card into my other PC (windows) and see if it will run at 1400x900.

I would rem out the modeline under the Monitor section and change the values of these two lines.
HorizSync 30-90
VertRefresh 56-75

Not sure if that is high enough for that resolution. May have to raise it a bit more.

also leave the 75 off the tail of the resolution line. Change to 1440x900

One thing you can try is running xorgsetup. It does a pretty good job of configuring X. I suspect that after you do you'll need to edit xorg.conf to put back the nVidia driver.

Hm. Never used xorgsetup before. I've always used xorgconfig. :P

FWIW I had a habit of using xorgconfig. So much so that I thought it was the only way to go (I'd long since known all of my hardware specs, which driver to use, etc.) I always had nice video, no probs. . . . .

Until Slackware 12.0 came along. I've (did and still do have) a dinasaur Matrox G450 AGP video adapter with 32 megs video memory. It uses the mga driver.

The freakin mga driver wasn't in the database using xorgconfig on Slackware 12.0 (I had no way to assign a correct driver for my video adapter).

I panicked and began googling. Uh oh the new X don't like to work nowadays with mga. Downloaded from Matrox (but never installed/tried or used it).

Then I saw on this forum someone praised xorgsetup

With nothing to lose (that vga driver and 60 Hz refresh on a 19 inch CRT monitor is not much fun though X and KDE did work).

I'll be darn! xorgsetup found and assigned the mga driver!

Why xorgconfig wouldn't show it (mga) for me as a choice, I don't know.

I've now some of the best if not the best video I've ever had. And it's due to merely doing a default run of xorgsetup. And I then compared its xorg.conf file with what I'd formerly grown accustomed to using in xorg.conf

I don't remember if I made any changes to xorg.conf. But if I did, they weren't much.

xorgsetup has always done a good job for me and it does back up your old xorg.conf just in case.

Also, you'll notice that xorgsetup will set up your keyboard too. In my case the volume controls on my Dell Latitude worked after running xorgsetup and I can set the Caps Lock as an extra CTRL. Sets up scroll mice, too.

If you type xorg <tab>, <tab> at the commandline you'll see your choices for configuring X. xorgsetup is the fastest and most user friendly.

Alright, I used xorgsetup, and I guess I made progress. There's no more virtual window, and the resolution is higher, but it's not the one I'm looking for. :/

It goes into 1280x1024. Even after I've listed "1440x900" first inside the modes line. I've even tried changing the default color depth to see if that would do anything.

Is there a command that would make xorg not use autodetected resolutions?
