I don't have a USB-C to HDMI. I bought one from China, but it will take a few months.

What else could I do?

Attention Fn + F2 to increase the brightness does not work on my PBP (kernel manjaro 5.6).


Try,  on the xorg terminal as a root user,
the command:

echo 3000> / sys / devices / platform / edp-backlight / backlight / brightness

This same command does not work from console (ctrl-alt-F2), it gives permission denied.

The problem is that the new brightness values now vary from 0 to 4095, a previous value set to 128 gives almost black screen.

It is advisable to prepare an image of the default system to be installed on an SD and use this system.

It happened to me the first time I used a 5.x kernel
In the dark I managed to change the brightness.
