Bug ID: 366346
Summary: Lenovo T460s + Docking station = external displays are
broken with Plasma 5
Product: KScreen
Version: 5.7.2
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: libkscreen
Assignee: se...@kde.org
Reporter: haiz...@gmail.com
I'm trying to run Plasma on Lenovo T460s (Skylake CPU, a different thing from
T460).
Multiscreen setup works fine when using laptops HDMI/DP outputs. However when
using Lenovo Ultradock, docking station, external displays are not recognized
properly. They are either not seen; seen but can not be activated; or screen
becomes garbled.
Booting with laptop plugged into docking station makes external displays work,
but after unplugging / sleeping / connecting external monitors through cables -
docking displays do not come back most of the times.
I've tested this with Kubuntu 16.04.1 + Plasma 5.6.5 and also with KDE Neon
Live CD 5.7.2
This is not hardware issue IMHO, since with stock Ubuntu 16.04.1 (Unity)
everything works flawless and it's the same kernel as Neon.
I'll be happy to provide more details if someone can guide me on how (i.e.
booting from Neon developer edition, etc.)
Reproducible: Always
