Lancer server Xorg sans ecran connecté (Nvidia)

under Linux

Share

Sur une machine avec une GTX 1070, Xorg refusait de se lancer si un écran n’était pas physiquement connecté à la carte. Le fichier /etc/X11/xorg.conf suivant fait l’affaire (c’est probablement sur les sections Screen qu’on peut simuler la conection des écrans). L’option Coolbits sert à activer les possibilités d’overclocking.
