[gentoo-user] [OT] external monitor

[Roger Mason]

Hello,

I have Gentoo running on a Toshiba Satellite M70 SR6.  I am using
ati-drivers to drive the Radeon Mobility X700 PCIE card, with this
xorg.conf (xorg 7.1.1):

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "aticonfig-Screen[0]" 0 0
        InputDevice    "Touchpad" "CorePointer"
        InputDevice    "Mouse0" "SendCoreEvents"
        InputDevice    "Keyboard0" "CoreKeyboard"
        Option  "BlankTime"  "5"  # Blank the screen after 5 minutes (Fake)
        Option  "StandbyTime"  "10"  # Turn off screen after 10 minutes (DPMS)
        Option  "SuspendTime"  "20"  # Full suspend after 20 minutes
        Option  "OffTime"  "30"  # Turn off after half an hour
EndSection

< -- snipped to save space -- >

Section "Screen"
        Identifier "aticonfig-Screen[0]"
        Device     "aticonfig-Device[0]"
        Monitor    "aticonfig-Monitor[0]"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
#               Modes "1280x800"
                Modes    "1280x1024"
        EndSubSection
EndSection

When I boot up without an external monitor or projector connected
I get 1280 x 800 dimensions on the lcd.  

Why is this, given that I specify 1280x1024 in the "screen" section above?

When an external monitor or projector is connected I get 1280 x 1024
dimensions on both lcd and monitor/projector.  Unfortunately, because
the real dimensions (in mm) of the (wide-screen) lcd and a standard
monitor are different, windows sized for the lcd are wrongly sized for
the monitor, and vice versa.  

Is there any way to have 1280x800 on the lcd and (simultaneously) 1280
x 1024 on the external monitor/projector?

Thanks,

Roger Mason

First, make sure you have xinerama in USE.  If not, add it, and do an
"emerge --newuse world".  Xinerama is the X extension that lets
applications know about multiple monitors, so that popups and font
sizes work out correctly.

I don't have an ATI graphics chip any more, but based on a thread [1]
on the rage3d forums, I believe you'll need the following lines in
your Device section:

        Option      "MerdgedFB" "true"
        Option	    "CRT2HSync" "30.0-90.0"
        Option      "CRT2VRefresh" "60-100"
        Option      "CRT2Position" "RightOf"
        Option      "MetaModes" "1280x800+1280x1024"
        Option	    "MergedXinerama" "on"
        Option	    "MergedNonRectangular" "on"
        Option	    "MergedXineramaCRT2IsScreen0" "false"

HTH,
-Richard

Thanks Richard, I'm compiling world now and will report back.

That now seems to be working, thanks.  The only problem remaining is
that objects that are equidimensional (circles etc) on the LCD are
stretched vertically on the external monitor/projector.  Do you know
of a fix for that?

Again, many thanks for you help.
