I am on i3 with my Dell XPS 13 9360.
I have a THunderbolt3-to-HDMI Adapter from pluggable and a monitor and a
cube mini projector.
My Problem is, that when I connect the cube mini projector to my adapter
and enable it via xrandr, I get projected my screen with rgb-errors,
like I can see my screen, but everything is destroyed with rgb- errors,
I mean the whole screen is broken with these colors, I really can't see
much on it.
The funny thing is, when I connect the projector to my docking station,
it works fine, so this must be a problem with the thunderbolt3-hdmi adapter.
Additionally, to fix this issue, I need to unplug the projector from the
adapter, plugin my monitor, plug out my monitor and plugin again the
projector, now the rgb-errors are away. STRANGE!!!
I would be very happy if you can tell me where I can find information,
e.g. which log files could be useful to you?
Also, if you know a solution, please don't be restrained to tell me.
