    Default Is tv overscan possible in dual head configuration??

    Hello all,

    I am running the latest proprietary ATI linux drivers(8.31.5) on ubuntu edgy.
    I have set up in dual head mode so i can put videos on the TV for my G/F while still using the computer for my important stuff.

    This setup is working fine except that i can't seem to enable overscan on the tv-out in dual head mode. i can do it in clone and big desktop!

    here is a snippet of my xorg.conf

    Code:
    Section "Device"
    	Identifier  "aticonfig-Device[0]"
    	Driver      "fglrx"
    	Option	    "VideoOverlay" "on"
    	Option	    "OpenGLOverlay" "off"
    	Option	    "KernelModuleParm" "agplock=0"
    	Option	    "ForceMonitors" "tdms1,tv"
    	Option	    "TVHPosAdj" "0"
    	Option	    "TVVPosAdj" "0"
    	Option	    "TVHSizeAdj" "100"
    	Option	    "TVVSizeAdj" "100"
    	Option	    "TVFormat" "PAL-I"
    	Option	    "TVStandard" "SCART"
    	Option	    "OverlayOnCRTC2" "0"
    	BusID       "PCI:5:0:0"
    EndSection
    
    Section "Device"
    	Identifier  "aticonfig-Device[1]"
    	Driver      "fglrx"
    	BusID       "PCI:5:0:0"

    EndSection

    When i do
    aticonfig --tv-info

    i get
    The TV is not connected
    The TV geometry is "100x100+0+0"
    The horizontal position limits are [0, 146571128]
    The vertical position limits are [147396624, 146486216]
    TV overscan mode is enabled

    But the tv is definitly connected(eg. i have an instance of x running on it and i can see it!) and the overscan is definitly not enabled!!!!!

    Any gurus out there know if this is possible/how to do it???

    Cheers

    Does overscan work if you enable the second display dynamically with aticonfig using the DDM options?

    Thanks for the help,

    Tried that, got this
    Code:
    root@edgy-eft:/home/dave# aticonfig --enable-monitor=tmds1,tv
    ati_dm: FGLRX_EnableDisplays failed when try to enable display: c.
    Using /etc/X11/xorg.conf
    Saved back-up to /etc/X11/xorg.conf.fglrx-24
    root@edgy-eft:/home/dave# aticonfig aticonfig --query-monitor
      Connected monitors: tv, tmds1
      Enabled monitors: tv, tmds1
    Warning : Option 'QueryMonitor' is exclusive, other options will be ignored.
    root@edgy-eft:/home/dave#
    It didn't seem to work but i can't mess with it at the moment as my g/f is home and is watching tv

    I'll try some more experimentation tomorrow.

    Had you tried using the dynamic options when using a "simple" configuration (e.g. aticonfig --initial and then enabling overscan)?

    My conf. works ok. (overscan included) http://www.phoronix.net/forums/showp...21&postcount=7
    after initial configuration, you enable overscan. With edgy and 8.31.5 it works better if you
    sudo -i and then
    cd /etc/X11/
    aticonfig [options] instead of
    sudo aticonfig [options] from your current directory.

    Why would you want overscan on dual-head since you wouldn't see the panels to control the second monitor?

    Thanks for the replies guys, I'll probably have to try these on the weekend now as my g/f's work schedule means that she'll be monopolising said television until the weekend

    Thanks
