Default TwinView without Xinerama

Hi,

I am trying to get TwinView working without Xinerama. E.g. I do not want a single desktop 2560 * 2048. I want two desktops at 1280 * 1024 each. The 'NoTwinViewXineramaInfo' option does not seem to have anything to do with this.

Does anybody know how to do this? With the "ati" or "mga" drivers, I simply specify two instances of the card and I can use the 'Xinerama' option turned on or off and achieve the desired effect. This does not seem to work with the "nvidia" driver.

-Alex

You can configure the NVIDIA Solaris graphics driver to treat each display device as a separate X screen, which can then optionally be joined with Xinerama. Please see Appendix O. Configuring Multiple X Screens on One Card in the README for additional information.

I believe I tried the instructions in that section of the README, but I will attempt it again.

Thanks again!

Apparently I didn't try hard enough. It works now and I can turn on/off Xinerama as I darn well please. I am very pleased. In case it helps anybody I am pasting my xorg.conf below.
