I have a triple boot Raspberry, and after an update of Raspbian, the gui won't start, when boot option in raspi-config is on Desktop I get Splashscreen of Raspbian Pixel and after this I get a black screen with terminal cursor, but I can't tape any command, I tried alt+ctrl+F4 but the cursor still blink and nothing happens.

Note that when boot option is defined on terminal command, and I launch sudo startx the gui start well, the problem is when I want it to start automatically.

  • I had this same problem and I found that it was because of a poor power supply.

  • I think you're right the problem was back just few days after everything was Ok, I didn't found a good power supply, I use a 5V 1.5A which is not enough for the raspberry pi 3. But why when I lunch startx from terminal I can use the gui without any problem?

It looks like there was a problem with tightVNC after removing it now the desktop starts properly

Edit: after few days I got the problem back.

    If you haven't sourced a 3A power supply yet, I'd suggest getting on that pronto. I've had all sorts of problems with the Pi3 and lesser power supplies. (runs great for a while, and eventually failing with a corrupted SD card etc)
