Title:
Kubuntu 18.04 does not display through mini-DP port on lenovo Helix 2
Status in linux package in Ubuntu:
Incomplete
Bug description:
(This is probably related to bug 1816860, but with different hardware
and a different appearance, so it is filed separately.)
Using the levovo Helix 2 attached to its Pro keyboard, it is not possible to
activate the monitor as attached.
The monitor is attached with a mini-DP-to-HDMI cable to the monitor (SONY),
and is - in this case, contrary to the bug mentioned before - detected as can
be seen by xrandr.
But then it gives up after some time (see attachment of System Settings
started from CLI and Xorg.log:

(and so it continues).
Connecting the tablet of the convertable itself with a micro-HDMI-to-
HDMI to that same monitor works fine, however.
