If I go in display settings I notice a second monitor Synaptics Inc 24'' which doesn't exist in reality. In Wayland after the screen stop flickering I don't have any other problem and that monitor is not present there. xrandr | grep -i ' connected' eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 174mm DP-1-3 connected (normal left inverted right x axis y axis) <-- I don't have anything connected to this port With Fedora 26 I don't have this problem but I'm not yet able to find what package is the culprit. I believe this problem is related to Displayport 1.2, I don't have any dock nor I need to connect more than 1 monitor and would be satisfied just having one interface.
