Public bug reported: Hello, I have a Dell XPS 13 9360 that connected via USB type C doc (Dell DS1000, the same as Dell WD-15) to 2 displays. And pretty often instead of good connection (that just works other times) I have a blank screen on external displays and main laptop screen. Ctrl+Alt+F1 doesn't work as well as Alt+PrtScr+B (that brings me to conclusion that it's a kernel bug). I've updated doc firmware to latest version using windows - it didn't work. Latest thunderbolt firmware update didn't work as well.
