[mythtv-users] MythTV compile problem w/ XvMC support

[Harry Orenstein]

Jarod,

Thanks for the quick reply.  I guess my terminology is muddled.  I meant a 
secondary display, but I don't think it's TwinView).  My XF86Config-4 file 
is below.  If you (or anyone) has a suggested config that would work with 
dual non-mirrored displays I would be extremely greatful.


Section "Files"
    # Multiple FontPath entries are allowed (they are concatenated together)
    # By default, Mandrake 6.0 and later now use a font server independent 
of
    # the X server to render fonts.
    FontPath "unix/:-1"

Section "ServerFlags"
    #DontZap # disable <Crtl><Alt><BS> (server abort)
    AllowMouseOpenFail # allows the server to start up even if the mouse 
doesn't work
    #DontZoom # disable <Crtl><Alt><KP_+>/<KP_-> (resolution switching)
