I have published a bash script to run GUI applications in docker: x11docker

I did several tests with kdeneon/all and x11docker. I know you have developed your own start script, but maybe some additional possibilities of x11docker are still of interest for you.

Some examples:

• KDE neon desktop with GPU acceleration and pulseaudio sound:
  x11docker --kwin-xwayland --gpu --pulseaudio kdeneon/all:user-lts
• Plasma compositor: x11docker --gpu startplasmacompositor
• Multiple outputs to simulate multimonitor:
  x11docker --kwin-xwayland --size=800x600 --gpu --output-count=2 kdeneon/all:user-lts
• Plasma in Wayland without X:
  x11docker --kwin --gpu --dbus --waylandenv kdeneon/all:user-lts plasmashell

Hello,
I did some tests with kdeneon/all:user-lts. As docker containers have no bluetooth device, bluedevil fails to start, but tries over and over again and does not stop. I get repeating error messages:

bluedevil: ObexManager operational changed false

Also, this causes high CPU usage.
I tried a test build adding this lines:

RUN apt-get remove -y bluedevil
RUN apt-get autoremove -y

This avoids the repeating error message, and the CPU calms down.

If I remember right, I've already seen this error on KDE installations years ago. Maybe bluedevil is running on every KDE installation as default, even if no bluetooth hardware is available? This could be a reason for often-heard "KDE is slow/eats too much CPU".
I'm not sure where this could be reported as a bug; maybe you as a KDE developer could tell this at the right place?
