Nope, again.
After some 5 or 10 minutes of working, the screen began to look like the old 
TV-sets not being synchronized (diagonal coloured bars), and then it went away 
completely. 

Before writing this message here, I let it run for half an hour or so, and it 
shows the display in xrandr, and then it doesn't show it. "You see it, and then 
you don't".
This here is like when xrandr shwos the display:

The System Settings in kubuntu never shows it (or I never saw it?)

Here I was lucky, and found xrandr between 'connected' and
'disconnected'. It looks crazy that it shows 'disconnected' and at the
same time givestiming information, doesn't it?:

And a few minutes later, in the inactive state, it does this here:

HDMI-1 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)


It looks a bit like those bug reports on FreeDesktop that exist on 'giving up', 
like 
106017 and 108529. 


Just for completeness: I have by now used two different cables, and even two 
different Helix 2 PRO keyboards (those that actually have the Mini-DP port). So 
it can't be a hardware problem of the PRO keyboard, I guess. 
(At this moment I cannot totally exclude a hardware problem of the tablet, the 
lenovo Helix 2, itself. I need to be careful now, I think. The tablet to which 
the other keyboard belongs doesn't have Linux installed.

Title:
  Kubuntu 18.04 does not display through mini-DP port on lenovo Helix 2

Status in linux package in Ubuntu:
  Confirmed

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.
