I have installed the most recent Raspbian Stretch lite (release: 2018-11-13) to a SanDisk ultra A1 micro SD card to use it for my Raspberry Pi model 3B. I connected a HDMI monitor and a USB keyboard to it.
The first Time I boot up the Raspberry Pi, everything works just fine. The Pi boots and I can use the keyboard and the monitor.
But when I shutdown the RaspberryPi with
sudo shutdown -h now after the first successful boot with a working monitor, and try to start it up again with "unplug and plug in power connection", the Pi will still boot, but my monitor doesnt receive any HDMI signal anymore. Apparently the keyboard doesn´t work too, because the caps lock control light doesn´t shine. From now on, I can only use the Pi with PuTTY via SSH.
I have tried to reflash Raspbian again and I get the same issue again. The first time, monitor and keyboard are working, and after that I am limited to PuTTY only.
I have also added the
hdmi_safe=1 tag inside the
/boot/config.txt but that didn´t change anything.
The question is: Is there something else I have to change in the settings, to enable the monitor to work every time since it is the Raspbian version without a desktop? Or is the problem somewhere else and if so, where?
Any help is appreciated.
UPDATE: I just found out, that:
- I only get a HDMI signal the very first time I plug in power
- after I
sudo shutdown -h nowand booting the Pi with a power cycle, I won´t get a HDMI signal, I´m limitet to PuTTY, but: If I then then type
sudo rebootover the SSH connection to start the Pi without a power cycle, I do receive a HDMI signal again.
