Nvidia card/driver and 2560x1440 Monitor

[NertSkull]

So I purchased a new monitor that lots of people have been talking about from Ebay. The Yamakasi Catleap 270

I plugged it into my Nvidia gtx 460 and first tried to boot up windows (I dual boot). Everything worked just perfect.

I then tried to boot up Kubuntu (12.04) and it went to a black screen, couldn't see anything. If I did ctrl+alt+F1 to get to a terminal, it worked and I could issue commands. So my computer wasn't frozen.

So I uninstalled all the nvidia drivers (I had the most current ones updated before adding the monitor) and when they were turned off, it works. Using the built in video drivers for kubuntu it works just fine.

But I'd really like to use the nivida drivers instead. So does anyone have any idea how I can do that? Clearly my video card works, since the monitor works in windows and with the default kubuntu drivers. So what do I do? I'm totally lost.

I have two monitors, and when I install the nvidia drivers again, and go to the nvidia-settings and have it "detect" the monitors. The new large one comes up with no identify information and a max resolution of like 320x460 (or something close to that).

Any ideas where I should go next? Thanks everyone.

So I made things a bit easier to work with.

I switched my two monitors around. So the new one is not in the primary DVI slot on the video card. So now my 2ndary monitor (an old one) will boot and show me a desktop using the nvidia drivers.

But the new monitor still remains black. But now, I can open nvidia settings and have it detect displays. It obviously picks up the old one just fine.

But for the new, high resolution, one it just says this.

DFP-2 (DFP-2 on GPU-0)

I can tell it to do twin view, but when I do it doesn't work, it just reverts back to the old setting. Also it tells me the max resolution is 640x480.

So it feels as though nvidia isn't recognizing the monitor at all. But I know it works, since it works in kubuntu when I turn off the nvidia driver and it works in windows.

Does this help any in getting closer to what to do?

I have the exact same problem.

"X screen information" in the Nvidia control panel reports that the screen is 640x480 pixels, measuring 217x163mm at 24bpp. Name: DFP-2.

My card is GTX 560Ti, driver is 295.40 x86_64

Any help would be appreciated

I should add that the monitor works perfectly under windows, detected as a "generic 2560x1440 display"

Allright, I have this solved on my system. So I'm going to document what I did here, in hopes that it may guide someone else to a possible solution. My situation may be unlike anyone elses, but this is what I did.

My Setup

Video Card = Nvidia GTX 460
Nvidia drivers = 295.49
OS = Kubuntu 12.04
Monitors = Asus VE247H (1920x1080) and Yamakasi Catleap Q270

The Problem

From what I can tell, the problem is that the monitor is not correctly reporting the EDID. Which is the information it sends to say what type of monitor it is, and everything about it. So the nvidia drivers can't figure it out.

Because of that, I decided to see if I could manually set it up by directly editing xorg.conf. I've never done that before, but I've got it working.

Resource I used to Fix

After searching for ages, I found this thread that directly confirmed my suspicion, and the basics of how to fix it.

http://www.codesim.com/tips/index.php?t=3

By using that link, you should in theory be able to fix yours. Thats all I used. I just had to play around with the xorg.conf to make it actually work for my system. You can see the link suggests this works with multiple monitors (Achieva Schimian, Catleap and Crossover)

Specifically fixed for my system

The problem I had with that, is I had never setup twinview manually. I was able get the Catleap up working alone really quick, but figuring out twinview was more difficult.

(Their example has twinview in it, but it wasn't the same as what my system needed. If you disable those two lines in their example, a single monitor should work just by pasting that into your xorg.conf)

I'll post my xorg.conf below twice. The first one I'll go through and explain as much as I can what I changed. And the 2nd time I'll just put it up straight as it is in my system.

I hope that helps people. Feel free to ask questions if what I did doesn't make sense. But I'm by no means an expert.

I know have my two monitors working using the Nvidia Drivers. Thanks for those who pointed me in the right direction.

Sidenotes
For those that may not know

xorg.conf is located in

/etc/X11/xorg.conf

If it doesn't exist, create it.

Also, this command is useful to restart to x-server

sudo service kdm restart     (if you are kubuntu)
sudo service gdm restart     (if you are ubuntu)

Also, since you often don't have a working monitor.

ctrl+alt+F1 and ctrl+alt+F7

will switch you back between terminal and graphical modes.

Hope that helps. Thanks

[Mearis]

That worked perfectly for me, thank you very much for the help!

[rockets]

Also worked for me. Catleap Q270 SE with NVIDIA GTX 560 on Kubuntu Lucid 10.04.

@NertSkull thanks for the instructions. They helped me get my Potalion 2710QW working in Ubuntu 12.04.

Both your instructions and the ones on codesim were for dual monitors and I only have one, so I had to modify the x.conf file to remove all the dual monitor stuff.

The lines I removed were:

    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "DFP-0"
    Option         "Xinerama" "0"

The line I changed was from this:

Option         "metamodes" "2560x1440_60 +0 +0, 2560x1440_60 +2560+0"

to this:

Option         "metamodes" "2560x1440_60 +0 +0"

I also changed some of the device and monitor strings for my setup. Full x.conf follows:

Section "Monitor"

I just ran across an alternate method for this fix - basically it uses a prebuilt EDID file for the monitor instead of typing it all out in the x.conf file. I tried it and it seems to work - I do like that it keeps your x.conf nice and tidy. I did get an error after boot saying that colord crashed, but I don't know if it's related (Ubuntu 12.04).

Hey - has anyone tried this with the Nvidia driver 304.43?

I can't seem to get it to work! (Although I had it working with the old driver).

Reason I want to upgrade is that this driver lets us do per physical screen colour correction, and I find the blue tint on my catleap is driving me a little crazy.

Anyone managed to get this working? I've tried both the custom EDID and also the modified xorg.conf file, and both either won't display or I get a really mangled screen.

Help?!

Many Thanks for all the good help contained here.
For a couple of days, I thought I was up the creek without a paddle
my korean Crossover 27Q monitor now works well on 12.04 @ 2560 x 1440

I patched an xorg.conf file together from the posts on this thread
after i finally got some ATI drivers to load for a Radeon 7750
