Saya baru-baru ini menginstal salinan baru Ubuntu 14.04 pada Dell M3800 saya yang memiliki kartu grafis Nvidia Quadro K1100M.
Kemudian saya juga menghubungkan monitor eksternal saya melalui HDMI (konektor HDMI ke DVI). Kemudian saya mulai melihat kinerja layar lambat di layar laptop saya. Maksud saya lamban adalah bahwa penekanan tombol atau tindakan saya tampaknya selalu tertinggal. Cukup lucu sepertinya ini hanya terjadi di layar laptop saya, monitor eksternal saya berfungsi dengan baik.
Saya telah memastikan untuk menginstal & menggunakan driver milik Nvidia 331.38.
Jadi saya memeriksa Pengaturan Ssytem saya> Menampilkan. Dan itu benar menampilkan 2 layar seperti yang terlihat di bawah ini.
Tapi kemudian saya pergi ke pengaturan Nvidia X Server & hanya menampilkan satu layar dengan satu resolusi layar besar seperti yang terlihat di bawah ini.
Saya pikir ini menyebabkan laptop saya memiliki kinerja lamban karena saya mengasumsikan bahwa monitor eksternal & layar laptop saya memiliki kecepatan refresh layar yang berbeda.
Saya dumping xorg.conf
& xandr
output di bawah ini,

. re: stereo, sepertinya ada banyak pilihan untuk itu seperti HDMI3d, Color Interleaved, Horizontal Interleaved dll.
