Resolució de pantalla 1024x768

Hi ha vegades que LliureX no reconeix les resolucions admeses pels dispositius d'eixida d'imatges (monitor o projector). El problema és molt greu si només podem utilitzar el Sistema a 800x600 quan projectem sobre una pissarra digital, ja que no es pot treballar de manera correcta.

Alguna opció per a obligar a LliureX a que treballe a resolució 1024x768 independenment del dispositiu que connectes?

Ací la tenim, gràcies al tècnic del SAI d'Elx.

1. Hem de preparar un fitxer de configuració amb el nom xorg.conf i el següent contingut:

xorg.conf (xorg 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

2. Copiem el fitxer xorg.conf en la carpeta de l'usuari (en l'exemple la carpeta anomenada lliurex)

3. Polsem Control+Alt+F1 per a iniciar sessió en terminal.

4. Iniciem com a usuari Administrador

5. Entrem com a root.

$ sudo su

6. Executem

$ /etc/init.d/gdm stop

7. Copiem el fitxer xorg.conf en /etc/X11

$ cp /home/lliurex/xorg.conf /etc/X11

8. Executem

$ /etc/init.d/gdm start

Seguint aquest passos hauriem de disposar de resolució 1024x768 en qualsevol monitor o projector que ho suporte.
