Ich möchte die Helligkeit meines externen Dell U2713HM-Monitors über DDC / IC ( DDC Wikipedia ) ändern , er ist über DisplayPort verbunden. Ich habe die integrierte Intel HD4000-Grafik.
Wenn ich sudo get-edid starte, bekomme ich:
get-edid: get-edid version 2.0.0

EDID blocks left is wrong.
Your EDID is probably invalid.
Der wichtige Teil ist wahrscheinlich:
Monitor and video card combination supports DDC2 transfers
Die Helligkeitstasten auf meiner Tastatur funktionieren ordnungsgemäß, da in Ubuntu 12.10 die Benachrichtigung über Änderungen der Hintergrundbeleuchtung angezeigt wird.
Was kann ich tun, um meine Helligkeit per Software anzupassen?
Danke für deine Antworten.
