Same problem here. When the nvidia GPU is prime-selected, I'm getting a black screen on startup, though Ubuntu booted and I can hear it working when I adjust sound volume with the keyboard. When intel GPU prime-selected, everything works fine. Like others who posted here, for me the GPU switching function worked before end of January, when after some updates (I really don't know which ones, I didn't follow) this error occured and keeps persisting. I tryed the solutions described on the posts #15 and #18 but they didn't work for me. Additionally I get an error message at startup: "System program problem detected. Do you want to report the problem now?". When I select "Report problem...", it shows a screen where I can check error details and it says "ExecutablePath /usr/bin/Xorg". Please keep this thread alive, we need a solution.
