Je te propose de modifier deux sections de ton xorg.conf ainsi : Section "Monitor" Identifier "L1715S" Option "DPMS" HorizSync 30-83 VertRefresh 56-75 EndSection
Section "Screen" Identifier "Default Screen" Device "Carte vidéo générique" Monitor "L1715S" DefaultDepth 24 SubSection "Display" Depth 1 Modes "1024x768" "832x624" "800x600" "640x480" "720x400" EndSubSection SubSection "Display" Depth 4 Modes "1024x768" "832x624" "800x600" "640x480" "720x400" EndSubSection SubSection "Display" Depth 8 Modes "1024x768" "832x624" "800x600" "640x480" "720x400" EndSubSection SubSection "Display" Depth 15 Modes "1024x768" "832x624" "800x600" "640x480" "720x400" EndSubSection SubSection "Display" Depth 16 Modes "1024x768" "832x624" "800x600" "640x480" "720x400" EndSubSection SubSection "Display" Depth 24 Modes "1024x768" "832x624" "800x600" "640x480" "720x400" EndSubSection EndSection Évidemment, si tu veux pouvoir accéder à une résolution supérieure à 1024x768, il te faudra rajouter les modes "1280x1024" et "1152x870". Bon courage !
