Hi,
I want to start using Ubuntu Mate on my Raspberry Pi 3B+, but I have a problem with starting in for first time. Pi is on, pluged to a monitor and the SD card with UM image is in, but the screen is all the time black. The red light is constantly on and the green one is flashing from time to time (without any pattern to distinguish).
With different memory card (with Raspbian) Pi is working normally.
I use:
-Raspberry Pi 3B+,
-Power Supply: 5V 2.5A,
-Memory Card: Kingston MicroSDHC 32 GB, Class 10, UHS-I / U1.
I appreciate any kind of support.
