I can't claim expertise, but I'd like to see the output of xrandr(1). It lists the available modes. From that, you can tell which modeline is in use. You ,ay be able to correct the problem with xrandr, too, with the --pos option. xrandr -d (from xrandr output ) --pos -60 The argument to '-d' is the display name shown in the xrandr output. You may also need to adjust the modeline parameters. (See man xorg.conf documentation and look at hsyncstart and hsyncend parameters. You can create a new modeline with the 'xrandr --newmode' command followed my an 'xrandr -d XXX -mode YYYY'. Perhaps someone with more expertise can give you a better idea. -- R.
