twinview, can't move windows between monitors

jsundqui · 01-18-07, 11:11 PM

Card: GeForce4 MX4000 Twin with two analogue D-subs

Distro: fresh Kubuntu Edgy install

I want to run twinview, with two monitors attached to the card. Default Xinerama install from Kubuntu very slow.

I installed driver from NVidia. Surprisingly, it said I had to use the legacy driver, so I did.

nvidia-xconfig originally still left the xinerama option in there, so I had to comment that out.

But since nvidia-xconfig seems to build upon the old/existing xorg.conf, when I run it under twinview, I get two separate displays. The mouse can travel from one to the other, but windows can't. Each window has it's own kpanel, too.

The problem is clear from my xorg.conf, where two screens are defined.

Here is the xorg.conf:

Code:

As you can see, I have two screens defined, so two X servers seem to be starting, one for each. If I comment out the second, then X won't start, since screen1 is referenced earlier.

So I think I can see the problem, but not sure how to fix it. Any suggestions?

Here is the full kitchen sink nvidia-bug-report.log

You're correct: this is not a TwinView configuration, but a dual screen configuration. You should remove "device1", "screen1" and "monitor1" entirely, along with the "Screen 1" line in the ServerLayout section. You also probably don't need all those modelines. In fact, the easiest thing to do might be to back up your current config and then run "nvidia-xconfig -a --twinview" to generate a new config from scratch.

I actually tried that after I posted my comment but ended up with a totally hosed X server, because even after I went back I got in the error log something about "resources already allocated" or similar. Running nvidia-xconfig --twinview got me back up and running ... with a working xinerama setup, not twinview.

I did that but got just a singe screen xorg.conf. So then I hand edited it to this which gives me what I needed. Only after I added in the custom metamodes did it work:
