I put a LCD 7" touchscreen on it, and the display is working (after having done the trick explained here). At least in text mode.
The whole is powered with two USB cables plugged on my workstation USB ports (so, with a good power supply I think). One cable is plugged on the rpi's micro-usb port, and the other on the display's port. If I don't plug the rpi's micro-usb port, there isn't enough current to active the Wifi dongle.
I manage to login through the tty console using the display and a connected keyboard, or via ssh from my workstation.
I have LXDE with lightdm installed, but I can't get the graphics using startx, nor using lightdm. Nothing appears, the screen turns black and I lose the keyboard control (I can't switch to tty2, tty3 etc.) The only way then is to reboot from ssh.
I have tried other things: xinit openbox, xinit startlxde-pi, startx, sudo systemctl start slim, etc.
The Xorg log doesn't seem to contain any errors:
