Xinerama, with acceleration

I have an nVidia GeForce FX 5900 XT graphics card, and two monitors. How do I get xinerama to work with opengl in both monitors?

Re: Xinerama, with acceleration

I'm afraid that I don't understand the question. Do you have the NVIDIA X driver installed and working?

Re: Xinerama, with acceleration

yes, I have the official nvidia driver installed and working, I have both monitors working, I have xinerama working. but opengl windows don't span between two monitors, and still have opengl working.

Re: Xinerama, with acceleration

Please generate and post a bug report, and provide instructions on how this problem can be reproduced.

Thanks,
Lonni

despite what the thing at the top says, my xorg.conf file is mostly hand-written

I start up kdm, login, and start blender. any portion of the program that I put in the second monitor doesn't display. the window displays, but the contents does not.

Re: Xinerama, with acceleration

Please generate and post a bug report, and provide instructions on how this problem can be reproduced.

Thanks,

Re: Xinerama, with acceleration

that is exactly what I just posted, I gave you my xorg.conf file, and all the information I can offer. I don't do anything special to create the problem, I just start up an opengl window, such as glxgears, drag it so that half of it is on one monitor, and half of it is on the other monitor. the half that is on the LCD monitor(monitor0), displays the opengl content such as the gears going, and the half that is on the CRT monitor(monitor1) does not display.

when I run blender and tell it to render, it puts the render window in the second monitor like I want it to, but nothing displays in the window.

Re: Xinerama, with acceleration

An xorg.conf is not a bug report. Please see the NVIDIA driver README, the web page where you downloaded the NVIDIA X driver, or here for how to generate a bug report:

Re: Xinerama, with acceleration

the log file is attached

Re: Xinerama, with acceleration

According to your bug report, you're not using Xinerama (its commented out in your xorg.conf). Was this bug report generated while the problem you're reporting was present?

Beyond that, I have a few questions:
0) Does this problem reproduce with 1.0-8178?
1) Why are you using the ConnectedMonitor option?
2) Per the NVIDIA README, please remove the dri and GLCore X modules from your X configuration. They are incompatible with the X nvidia driver.

Thanks,
Lonni

1) I am using the CommectedMonitor option, to force my flat panel as display0, the graphics card default is to have DVI as display1 and VGA as display0

3) I just did and the results remain the same.

oh, and one other iteresting tidbit, when I'm running in xinerama, nvidia-settings only recognizes one display. and it sometimes causes my computer to freeze when I'm running xinerama and switch to console, and back or to another x server.

Re: Xinerama, with acceleration

Your usage of the ConnectedMonitor option is incorrect, and that alone might be causing, or at least contributing to the problem you're experiencing. Per the NVIDIA README, the ConnectedMonitor option is meant solely to tell the driver about the existence of a display device that it could not normally probe for/detect on its own when X is started. ConnectedMonitor can *NOT* be used to force a display device to be the primary/secondary/etc display device. Attempts to do so will not work, and potentially confuse the driver resulting in unexpected results.

That said, I'd suggest commenting our your usage of ConnectedMonitor, and seeing if that helps at all.

If it does not, you're going to need to install 1.0-8178. 1.0-7174 is no longer supported for your videocard, and you could possibly be hitting a bug in 1.0-7174 that was long ago fixed in a later driver version.
