TwinView, fullscreen on TV

[brosen]

I've managed to get both crt and tv working, but have problems with the resolution on the tv.

At 1024x768,800x600 the screen doesn't fit on the TV (which is as it should be I assume) but NULL,800x600 or 800x600,800x600 also give me a larger virtual screen. Not very useful for watching those movies!

Any suggestions?

Thanks,
Bo

TwinView will compute the virtual desktop size by creating a bounding box using the largest mode listed in metamodes ... so if your metamode is :
Option "MetaModes" "1024x768,800x600; 800x600,800x600~

The bounding box is 2048x1536 ... (xinerama doesn't allow you to have a irregular bounding box) ... so the second head will use 800x600 but will pan across a 1024x768 area.

Even if you switch modes using <ctrl>+<alt>+<-> ... the desktop size don't change .. so both heads will pan across a 1024x768 area.

To solve it, you must run two X ... one in your TV and another in your CRT ... using the xnested or xggi xservers .....

Maybe you can find more info here:

Thanks, hopefully I'll be able to make some sense of Xnest, but looking at it I'm doubtful ;-)
