--- Comment #223 from Joe <jchevar...@gmail.com> --- I have mainly good luck with the changes now and my laptop. I get some really weird stuff with my docking station though. I have a Thinkpad P50 with the corresponding Lenovo dock (Thinkpad Workstation Dock 40A5). When I have my monitor plugged into the HDMI port on the dock itself, SDDM displays both screens correctly. However, if I attach it (either laptop to the dock, or hdmi to the dock) when I already have a session open/logged in, all hell breaks loose. It basically continuously cycles the laptop's monitor and the external monitor on/off/detecting display - as if I was manually plugging/unplugging the cable from the dock and it. Unplugging it causes it to immediately stop and my laptop screen is restored. Plugging it directly into the HDMI port (Quadro m2000m) is also completely fine. I have tried two different docks (both with up to date bios) and two different P50s (other had a Quadro m1000m). Seems to be a Plasma only issue, as if I connect everything before logging in via SDDM it all works (and seems to work under other DEs in general) - it just goes crazy when I attempt to attach it when already logged in. -- You are receiving this mail because: You are watching all bug changes.
