I'd suggest that you consider using xrandr. Look to see what interfaces it recognises, by default. Plug in the external monitor and use xrandr to activate the interface. For example, with my Dell Latitude E5500 I see the following -- [Duo2 ~]$ xrandr Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192 LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1280x800 60.0*+ 59.8 59.9 40.0 1280x768 59.9 60.0 1024x768 60.0 800x600 60.3 56.2 848x480 60.0 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) TV1 disconnected (normal left inverted right x axis y axis) [Duo2 ~]$ Alan. _______________________________________________ elrepo mailing list elrepo@lists.elrepo.org http://lists.elrepo.org/mailman/listinfo/elrepo
