[mythtv-users] Can I change the default screen?

[DaveD]

I have a dual head Nvidia 5200 with DVI driving my 17" monitor and 
analog (15-pin) driving my 1080p LCD TV (actually a 37" monitor with 
external tuner).  With the dual head, single card, I can only have one 
display with two screens and only one of the screens gets the video 
overlay, screen 0.  I would like that to be the TV so I can adjust 
picture settings (brightness, contrast, etc) and take some of the load 
off of the CPU during video playback.  I am running KDE with two 
separate desktops, same user.  I thought I could do multiseat, but found 
that only works with dual DISPLAYs, not just dual SCREENs.  In other 
words, multiseat (different user on each display) requires dual video 
cards, which I can not accommodate (box is full!).

Sending screen 0 (DISPLAY :0.0) to the TV poses some problems when  my 
wife is watching the TV and I am working on the computer using the 
monitor on screen 1 (DISPLAY :0.1).  If I try to reboot, the logout 
prompt is displayed on the TV, which I don't see because the TV input is 
set to Tuner instead of PC.  If I put in a CDROM, the "What do you want 
to do" prompt, again, is sent to screen 0.  I have to wait for a 
commercial (remember commercials?) to switch the TV input to PC so I can 
see the prompt and respond.  There are LOTs of cases where things are 
sent to screen 0 by default.

What I would like to do is change my default display to be on screen 1.  
I would like the login prompt to be displayed on display :0.1 and my 
second desktop to be on :0.0.  Anyone heard of this?  Is it possible?  
Is there a better list to post this question to (I tried KDE forum but 
no luck)?
