Si no tenemos una tarjeta gráfica con doble salida (VGA y DVi) pero tenemos 2 tarjetas PCI, o una AGP y una PCI podemos usar las 2 salidas VGA y conectar sendos monitores.
Mis tarjetas son (según lspci) : la 1º una nVidia GeForce4 MX 440 AGP 8x y la 2º una S3 Inc. ViRGE/GX2.
La tarjeta nVidia va conectada a un monitor TFT Arnos Instruments F-417 de 1280x1024 puntos de resolución y la S3 a un CRT LG Studioworks 520Si de 1024x768.

Presenta alguna inestabilidad a la hora de arrancar, a veces hay que resetear y repetir el arranque con recovery mode ( cp xorg.conf-dos-monitores-dos-tarjetas xrog.conf y luego exit ).
Tambien observo que se congela el sistema al cerrar la sesion X. No vuelve al gdm, se queda la pantalla en negro y no responde a nada salvo el botón de reset.
Por lo demás, una vez que arranca funciona con las dos pantallas sin problema.
