To all the 1900x1200 & 1680x1050 LCD monitor owners...

[russofris]

Good evening,

I just picked up a Dell 2407 WFP. Here are the relevant sections of my xorg.conf that I added to get things working.

I am certain that this won't work for people with a <155mhz pixel clock

I hope that this helps others with similar hardware configs get 1900x1200 going. I'm currently running 8774.

Thank you for your time,

Hi @all,

after long time of using my display in Analog (D-Sub) mode, I found a solution to get it work at 1920x1200 with DVI-D and my single-link Geforce 6800 GT (AGP).

this is what I have done.

Xorg.conf

Section "Monitor"
Identifier "BenQ FP231W"
Option "DPMS"
HorizSync 30-81
VertRefresh 50-76
Option "ModeValidation" "NoMaxPClkCheck"
Modeline "1920x1200" 154.0 1920 1968 2000 2080 1200 1203 1209 1235 +Hsync -Vsync
EndSection

I used this Modeline (Not really needed) which I found on the Inet and used this option which I found in the readme of the Beta driver (Linux-x86-1.0-9625) (Option "ModeValidation" "NoMaxPClkCheck").

Note I have tested this without any Modeline and it worked too. I Think in different cases you have to use one or not, this is a think you have to try.

So I couldn't believe it as I restartet GDM an had the full resolution of 1920x1200.

at least a little info of my Xorg.0.log

I hope this will help someone.

But don't forget everything you do is on your own RISK

I have some very strange problems with the acer in conjunction with NVIDIA cards.
This might be simply because I have 2 different kinds of monitors installed.

Anyway, I have a linux box with an FX5500, and a windows box with an FX6200.

I have a Samsung 173v plugged into the VGA and the Acer AL2216W plugged into my DVI. On the 6200 with Windows, with the latest NVidia drivers, I could switch to the proper resolution (1680x1050) and see images no problems, but watching videos was HORRIBLE - the resolution got all blocky and pixelated. Also, I can't get antialiasing working from GTK apps in windows as soon as the second monitor is connected - I can only get antialiasing with a single monitor attached. Which really sucks.

Anyway, I don't like Windows, I'd rather use Linux (kanotix - debian unstable) with my fx5500. I was using an older NVIdia driver (8xxx - I can't remember exactly which version now), with Xorg 7.0 which worked fine for about a month (october) and then in early november I upgraded to xorg 7.1.0-7 and it broke my previously installed driver, so I had to upgrade - now it's rev9629.

Now, my Acer is stuck in 1024x768! It seems not to matter what I put in my xorg.conf, it just keeps stepping down to 1024x768. I'd like to at least be able to go to 1400x900 again, but my old xorg.conf doesn't work on the new driver at all.

Anyway, I'm attaching my xorg.conf files here. The one I am using currently is based on some other ones I saw posted here. The one with nv8xxx in it was the one that worked fine with my older driver. I hope someone can help me get back to a reasonable resolution (even 1400x900 is preferable to what it is now!). I *know* it is a problem with my xorg.conf or the NVidia driver, because I saw it in the correct resolution earlier. I don't want to switch back to windows where it is all blocky and pixellated and my antialiasing doesn't work.

Help?
