TwinView help?
 

Okay, so I've tried everything in the ReadMe trying to get TwinView to work. I have a two-port GeForce 4 ti4600 (one VGA and one DVI adapted to VGA) with a CRT attached to the VGA and a LCD attached to the DVI. When I load up my edited XF86Config-4 I get an image on the second monitor, but nothing on the first. My XF86Config-4 is below, can anyone help me? Has anyone had this problem?
I've commented out the stuff I added, it's sort of a Xinerama/TwinView hybrid at the moment...

nvidia configuration problem
 

I think your problem may be that in your config file you identify the displays as CRT. The DVI flat panel display should be identified as DFP
Option "ConnectedMonitor" "CRT,DFP"

Hope this helps

Use the nvidia driver, currently you have this which uses the xfree86 driver:
Driver "nv"

What Bill said is correct too.

Both are excellent advice, however I've tried both to no avail. Identifying the second monitor as DFP causes XFree86 to tell me that there are no monitors attached. Identifying the driver as "nvidia" also causes nothing to work....

The X error log may give you some more detail on why this is failing. I recommend that you try configuring each screen alone first, then worry about setting up the twinview option. I personally do not recommend using Xinerama and twinview together - I would set Xinerama to off.
I also do not recommend that you have a second screen defined. The twinview setup implicitly identifies the second screen. Adding another separate screen definition may be part of the problem.

Here is a copy of one of my config files if it helps. Look at the serverlayout and screen sections

I got it working, thanks very much for everyone's help. I'm not sure exactly what was wrong because I just fiddled with things and all of a sudden I had a picture on both monitors... So I fiddled more with what made sense and got it to work perfectly. I'm really happpy with it and I'll post my config later so others can look at it.

Would you please post your working config file for twinview?

thanks

TwinView
 

I have the same Video card using two matching Hp CRTs. I can't enable Twinview. Does anyone see where I am going wrong?

Zog:

Just got my Quadro 400 NVS card this week & had the same problem. Looks like you need to specify a MetaMode for EACH monitor, like this:

Option "MetaModes" "1600x1200,1600x1200"

Otherwise, the second screen defaults to NULL. Hope that helps.
