Dual Head - Primary display

Message

Dipy74 · Post by **Dipy74** » Sat May 26, 2007 10:40 am

Hi,
I have a latop, and an external LCD screen which I connect to my laptop using the VGA output (graphic card is an ATI Radeon Mobility X600).
I'm trying to use dual head, but I've got a little problem: it works great (also with different resolutions on both screens), but the 'primary' display (the one kdm is launched on, and the one with my 'standard' desktop) is the external LCD screen. I would like it to be the lcd screen of my laptop instead, because this is the one I will use (the other will be used to dispaly video, web, ...).
I tried many thing in my xorg.conf (such as switching the screen names, ...), but can't get anything to work.

Here is my full xorg.conf:

Is what I'm trying to do possible (I've seen many person asking the same thing, but with no result)? If yes, how to do it; if no, is there a reason for not allowing it ?

Also, an other question: when using dual head, I can't get to play a video on neither screen: on both it just show a blue window (just like if the overlay was on the other screen). What option do I need to add to my device configuration to be able to play a video on at least one screen ?

Thanks

I just recently got around to set up dual head with my Radeon 9600 and fglrx. It's set up the way you want to, though you would need to tailor for a few differences

For the other question, you should probably check if your video player supports Xinerama. I added xinerame to my use flags and did emerge world --deep --update --newuse

Edit: Forgot to mention, the above was generated with the aticonfig utility, something like

Code: Select all

aticonfig --initial=dual-head --screen-layout=above

Thanks for your answer, but this doesn't seem to work like I want: the main differences between our xorg.conf is the device section, so I simply copied all yours to my xorg.conf, and result is still the same: the primary display with KDM and the 'default' desktop is the external CRT screen, rather than my laptop's screen. So the question still remains, is it possible to specify which screen is the master screen on a dual head configuration with an ATI card, and the fglrx drivers?

Thanks

Altering the following might switch them around, at least it does for me

Code: Select all

Option       "MonitorLayout" "NONE, AUTO"

just switch NONE to AUTO and vice-versa
