intel-2.6.99.902 support primary output for RandR 1.3?

[GordonYuan at viatech.com.cn]

Dear all,

    The same thing happens on Intel platform with the package xf86-video-intel-2.6.99.902. I enable VGA and HDMI device, and make HDMI shows the right contents of VGA. 

    Some documents mentions that the primary output holds the toolbar, shows the GDM login dialog and screensaver unlock dialog. So I thought the toolbar will move to the HDMI screen if I use the command “xrandr --output HDMI --primary”. But nothing happens. After I use the command “xrandr --verbose”, I find that CRTC of VGA and HDMI exchanges, but the display make no difference. 

    I use the OS Ubuntu 9.04 alpha 6 and xrandr 1.2.99.4.

    I’m puzzled now. Have the xf86-video-intel-2.6.99.902 not supported primary output? Or am I misunderstanding about the meaning of primary output?

    Thanks!

Best wishes,

Gordon

Subject: randr1.3 primary output using?

 

Dear All:

    Recently I am using RandR1.3, I found a little confuse with RandR1.3 primary output definition.

    What is this parameter for?

 

    I use the command

 xrandr  --output  VGA  --primary 

    I found if the VGA occupied the IGA2, after using the command line it occupied IGA1, see the info from xrandr --verbose 

    Before command

    In my opinion, because the crtc is changed we need to redraw the screen, but actually the screen do not redraw, so I now is a little confused about the function of this command? what is the right behavior of the command?

    Thanks!
