It always happen to the monitor on the right (DP1-1), but simply because it is the "secondary" monitor of the MST setup. The laptop's mDP cable is attached to the monitor on the left (DP1-8), the output of which is then attached to the monitor on the right (DP1-1). If I switch them nothing changes, the "black" one is always the "secondary". > If your laptop has an HDMI port, could you hook up one of the Dell displays > to that and see > if it shows the problem as well? It doesn't have HDMI, but I have an mDP->HDMI adapter if you want. Anyway I think the problem is MST, so I can simply disable it in the monitor on the left and the right monitor will be a duplicate, not seen by the system. This is how I disable MST on the left monitor: 1) https://drive.google.com/open?id=0Bwe9Wtc-5xF1dU5qU0RYQ2ZiT28 2) https://drive.google.com/open?id=0Bwe9Wtc-5xF1eFVqMERfTlVlNms Here is the video with MST turned off: https://www.youtube.com/watch?v=a2hgzNzo8PM&feature=youtu.be First thing to notice: there is no compositor settings window anymore at startup! This is a good sign, because you are not supposed to see it unless there are troubles with compositing. Second thing to notice: no back screens. Third thing to notice: Crash Reporting Assistant still pops up after disabling the laptop's main monitor (see attached plasma_backtrace_nomst.log) > Love your videos and screen setup, by the way. :) Thanks, I both love and hate my multi-screen setup. I love it because it's awesome to code with it and a mechanical keyboard. I hate it because I had lots of multi-screen troubles with Plasma and I love to use Plasma as well :) -- You are receiving this mail because: You are watching all bug changes.
