Why does the monitor fall off on Orange PI?

Question

Microcontrollers

Good day, fellow villagers! I recently bought myself an Orange Pi, uploaded the Lubuntu image to a USB flash drive and connected the monitor via an HDMI to VGA adapter, a mouse, and a keyboard.
Everything seems to be fine, but the monitor, for some reason, turns off after 20 seconds. When I juggle the monitor to a hot one, the image is there, but, again, for 20 seconds.
What could be the problem?

Answer 1

Linux is furious that these adapters do not correctly give out information about themselves and you need to configure everything with pens Adapter from hdmi to vga in raspberry pi 2

Answer 2

I won’t tell you what the problem is, but there were special settings in raspbian for such cases, it might be worth digging in this direction

Answer 3

The problem may lie in the hdmi-vga converter itself, namely, in a very hot chip. After the failure of one converter, I bought another and sawed a hole in it for a chip, stuck a copper plate and installed a small cooler. It may look very collective, but a year has passed, the flight is normal.
