1. Sağlayıcıları listeleyin
İlk olarak, sisteminizdeki “sağlayıcıların” (yani grafik yongalarının) sayısını listeleyin:
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x1fb cap: 0x1, Source Output crtcs: 4 outputs: 8 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x45 cap: 0x2, Sink Output crtcs: 3 outputs: 3 associated providers: 1 name:modesetting
Bu size grafik kartlarını göstermezse, daha fazla araştırma yapmanız gerekir; örneğin, BIOS’unuzda tümleşik GPU devre dışı bırakılmış olabilir.
2. Sağlayıcıları bağlayın
Ardından, sağlayıcıları birbirine “bağlamamız” gerekiyor (bu, bulmakta zorlandığım kısım):
xrandr --setprovideroutputsource 1 0
3. Görüntü çıkışını etkinleştirin
Olası çıkış bağlantı noktalarının bir listesini almak için aşağıdakileri kullanın:

Ve sonra sırayla her birini etkinleştirmeyi deneyin:
xrandr --output HDMI-1-1 --auto
Ve umarım ekran(lar)ınız açılır.
