Saya ingin mengubah kecerahan pada monitor Dell U2713HM eksternal saya melalui DDC / IC ( DDC Wikipedia ), terhubung melalui DisplayPort. Saya memiliki grafis Intel HD4000 terintegrasi.
Ketika saya menjalankan sudo menjadi edid, saya mendapatkan:

EDID blocks left is wrong.
Your EDID is probably invalid.
Bagian yang penting mungkin adalah:
Monitor and video card combination supports DDC2 transfers
Tombol kecerahan pada keyboard saya berfungsi dengan baik, karena saya melihat lampu latar-perubahan-pemberitahuan di Ubuntu 12.10.
Apa yang dapat saya lakukan untuk menyesuaikan kecerahan melalui perangkat lunak?
Terima kasih atas jawaban anda
