Bei meinem Ubuntu: 17.10 wird beim 2. Monitor nicht die Auflösung 1920x1080 erkannt. Der erste Monitor ist mit einem Display Port zu VGA Adapter angeschlossen. Hier ist alles ok. Der 2. Monitor ist per HDMI angeschlossen. lspci -nnk | grep "VGA\|'Kern'\|3D\|Display" -A2 gibt folgendes zurück:
00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 620 [8086:5916] (rev 02) Subsystem: Intel Corporation HD Graphics 620 [8086:0000] Kernel driver in use: i915

Habe das hier versucht: https://askubuntu.com/questions/973499/wayland-how-to-set-a-custom-resolution/973582#973582 Leider ohne Erfolg.
Wenn ich den Rechner neu Starte bleiben die Monitore Schwarz, sodass ich GRUB wieder manuell anpassen muss. Hat jemand eine Idee wie ich hier am besten vorgehen kann um das Problem einzugrenzen? Danke schonmal.
