Nvidia Separate X Screen Help

CynicalPride · October 3, 2008, 5:03am

Hello,

I am currently running openSUSE 11.0 x86_64, using KDE 3.5. I have a Nvidia 7600GT graphics card, with a Viewsonic VA720, and a Samsung Syncmaster 940BW connected.

I have the current nvidia driver 173.14.12. Configured to run Separate X screens via nvidia-settings.

My problem is, screen:0(syncmaster 940BW 1440x900) is the primary screen and the resolution is correct on the monitor, but the KDE desktop overlay is messed up. My panel bar is shorter than the width of the monitor, and the desktop extends below the bottom of the monitor. On the login screen, the bottom is cut off, and the right hand side is extended. screen:1(Viewsonic va720 1280x1024) is operating perfectly.

So my question is, how can I adjust my desktop size on screen:0 to that it is the correct size of the monitor. I have included my X config file. If you need screenshots, just ask.

Have you started x after your nvidia configuration?

CynicalPride · October 3, 2008, 5:22am

I have everything up and running, X is running, KDE 3.5 is loaded and working, and everything is usable, Just the desktop on the primary monitor isn’t right.

Thanks

Hello,

Hi
I would recommend backup your xorg.conf file and run through using sax2
rather than the nvidia one. If it doesn’t work you can just copy the
backup back and restart the X server.

Here is a link to my desktop, it’s a SLED machine but runs dual
monitors to have a look at http://nopaste.com/p/amwBisOW3

If screen 0 (samsung) has an auto image fit in the control panel you can try it and see if the resolution correspond to your nvidia settings before attempting another move.

CynicalPride · October 3, 2008, 6:13am

Hello,

Screen:0 Samsung Syncmaster 940BW reports 1440x900 resolution in the auto image setting. The resolution is correct on both monitor, the problem lies in the desktop size itself, It’s almost as if KDE is not setting the desktop size correctly. The bottom of the screen is cut off, and the right side is “extended”

http://www.myinfinity.net/screen0.jpg Screen:0
http://www.myinfinity.net/screen0app.jpg Screen:0 showing bottom cut off
http://www.myinfinity.net/screen1.jpg Screen:1 showing working perfectly
http://www.myinfinity.net/screen1app.jpg Screen:1 showing working perfectly with same app running

Thanks

Just for testing
Logout of kde and login using icewm or xfwvm if those were preinstalled and see if the problem persists.

CynicalPride · October 3, 2008, 6:25am

The login screen is also affected by this issue, I am unable to select a session type due to the fact that the bottom of the screen is cut off. Being that this is also affecting the login screen, I would have to imagine that it would also be present in other GUI’s, I will however check that out right now. Please take a look at the pictures I posted in my last link. I think they will help explain more of what my problem is.

Problem Exist in Gnome
Problem Exist in KDE4
Couldn’t duplicate problem in IceWM due to the fact that the second desktop wouldn’t appear.

Thanks
Mark Brown

conram · October 3, 2008, 6:35am

I can see it.
While in the login screen can you try pressing the samsung auto image adjust to see if you can resize the screen to fit the whole area of the login screen.

CynicalPride · October 3, 2008, 6:39am

Auto image adjust doesn’t work on the syncmaster, It just reports the current mode that the monitor is in, and reports that auto image is not available. It will not let me adjust the image manually either.

Thanks
Mark Brown

conram · October 3, 2008, 6:52am

I see it might be because the samsung is the one using the DVI.
I am not using my second monitor I brought it down the basement so I can’t test it here.
Can you try changing your two monitors setting in the nvidia-settings config to make the samsung as the second monitor and the other as the default.

CynicalPride · October 3, 2008, 7:02am

I have switched the viewsonic to screen:0 and the syncmaster to screen:1. The problem persist. I have attached the new xorg.conf file, As well as 2 new Screen shots

Hello,

Could still use some help on this problem if anyone has any idea’s

Thanks

I don’t know if this problem still going on, it’s been a while.
I just recalled that I have a samsung lcd monitor before and sometimes behaves almost the same as yours when I was still using it in the previuos suse versions. The cd that came with it with the monitor driver can be read by suse and can be installed using yast2. I am not sure now because the latest suse version just automatically recognize my viewsonic monitor so I haven’t use yast in configuring it.
