Thanks for the comments, but it did not solve my problem.
When I try to run the command xrandr --output HDMI-1 --rotate left it returns me that the hdmi-1 output could not be found.
“warning: output HDMI-1 not found; ignoring”
When I run the command xrandr -q, which lists all the video outputs, it shows me only this solid DEFAULT CONNECTED, as shown in the image below.
What do I need to do?
