Layar Berkedip dengan driver NVIDIA
Saya baru saja menyiapkan instalasi linux Arch saya sendiri. Saya mengalami masalah dengan salah satu monitor di pengaturan monitor ganda saya. Sesekali, tampaknya secara acak, monitor saya akan menjadi hitam selama sedetik sebelum menyegarkan. Ini cukup membuat frustrasi. Ini hanya terjadi dengan salah satu monitor saya, monitor lain sama sekali tidak terpengaruh. Saya telah mencoba segala macam hal dan membaca banyak posting forum, tetapi saya tidak dapat memperbaiki masalah ini.
Saya menjalankan driver nvidia-450, dengan GTX 1080 TI. Monitor masalah terhubung melalui displayport dan merupakan monitor 2k. Monitor lainnya juga terhubung melalui displayport dan merupakan monitor 1080p.
Berikut adalah beberapa keluaran perintah yang mungkin membantu, diedit untuk bagian yang relevan:

Beri tahu saya jika Anda memerlukan info lebih lanjut. Masalah ini membuatku gila.
Jawaban
Ternyata, masalah kelap-kelip layar saya disebabkan oleh kompositor saya: picom. Saya memecahkan masalah ini dengan mengubah backend saya dari glx ke xrender di file konfigurasi picom saya.
