tty: 105x33
Message: No advanced graphics data found on this system.
THIS is the data about my monitor. "Message" says did no knows nothing about
Well, the monitor behaves extrange, with a *blinking* ambar light not
mentioned in the monitor manual troubleshooting
The monitor has in the back a extrange hole near a padlock symbol, maybe
for a certain type of screw driver. I have no luck screwing there.
TIA
This would be a fully functional inxi output.

Yours shows tty, because for some reason, it hasn't loaded *anything else* .
Display manager, session manager ?

I would say, to start, check that the HDMI cable is plugged in.
Maybe the light is flashing yellow, because the signal is out of range.
No signal whatsoever, the monitor LED should be blue.
Signal working, monitor LED should be yellow.
Ideally, signal out of range, OSD box onscreen should notify you.
Time to check for a /var/log/Xorg... log file which keeps
track of the display discovery process.
There is get-edid and xrandr.
https://unix.stackexchange.com/questions/114359/how-to-get-edid-for-a-single-monitor
$ monitor-edid
EISA ID: LEN4036
EDID version: 1.3
EDID extension blocks: 0
Screen size: 30.3 cm x 19.0 cm (14.08 inches, aspect ratio 16/10 = 1.59)
Gamma: 2.2
Digital signal
$ get_edid | parse_edid
Using such EDID-related command, proves that the serial bus on the HDMI cable
is working.
Whereas xrandr, relies on the DISPLAY variable being set,
and an Xorg server process successfully running. If xrandr cannot contact
the X display server, then you should not expect output.
Your output does say an Xorg is running, 1.20.8, so DISPLAY=:0
should be working. Maybe something like this.
$ xrandr -display :0 --verbose
We know there's no terminal of course. Inxi told us that. Using xrandr
is no better than doing
$ xterm -display :0
sort of thing.
If Wayland was present, I presume it provides enough backward
compatible features, to make anything X-related, to work.
