USB-C hub external display is recognized but screen stays black
A new x380 Thinkpad with USB-C dock running KDE 17.?.
Everything works if I connect my laptop directly with an HDMI cable or my HDMI to DisplayPort to the external LG monitor. Also, the setup works if Windows is booted. The Old OneLink+ with my x270 works with this monitor as well, so I figure it must be Ubuntu related, right?
