I have a problem with my LCD Touchscreen.
I'm using a 3.5inch Waveshare LCD and Raspberry Pi 3 with Raspbian OS. The LCD usually worked and could display the desktop. But then suddenly it was unable to display the desktop. The screen showed just a black screen with a pointer, but the pointer won't move even though I'm using wireless mouse.
I can log in via SSH using PuTTY and can see the desktop on my laptop using VNC.
At first, the LCD displayed the boot command line, but then it freezes when trying to display the desktop. Its touch screen function also does not work.
I also got the error message
rc.local compatibility failed when booting the Pi.
So, why can't my LCD display the desktop? I didn't make any changes to the configuration.
