Hola. Ahora si me funciona. Te paso el xorg.conf mio para que veas la diferencias: # xorg.conf (X.Org X Window System server configuration file) # # This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database. # # Edit this file with caution, and see the xorg.conf manual page. # (Type "man xorg.conf" at the shell prompt.) # # This file is automatically updated on xserver-xorg package upgrades *only* # if it has not been modified since the last upgrade of the xserver-xorg # package. # # If you have edited this file but would like it to be automatically updated # again, run the following command: # sudo dpkg-reconfigure -phigh xserver-xorg Section "InputDevice" Identifier "Generic Keyboard" Driver "kbd" Option "XkbRules" "xorg" Option "XkbModel" "pc104" Option "XkbLayout" "es" EndSection Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" EndSection Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" SubSection "Display" Viewport 0 0 Depth 24 Modes "1024x768" EndSubSection EndSection Sólo ha añadido la sección Display, es una subsección. Y está copiada del xorg.conf.new que le hice a este equipo. Asi que, si puedes hacer el xorg.conf.new, podriamos editarlo sin ningún problema para que esté sólo una resolución por defecto y la que nosotros queramos. Saludos. -- José A.
