Hi,
I know this thread is over a year old, but I join in anyway.

I bought a USB-C to HDMI cable myself and found that this did not work. After some searching online I came across this thread.
At first I didn't want to believe that it was not possible to connect an external monitor (wired), so I had to search a little more.

As @kugiigi mentions, the hardware does not support this directly because the Pixel 3a only has USB 2 (USB 3 is required), but then I came across a thread from another forum that mentions a video on youtube titled "Pixel 3 to HDMI Video Output (using a WIRED adapter)". (I was not allowed to paste the link here)

Here you can see that it is possible with the DisplayLink technology (but on Android you have to download an app for this).
So then the question is, has anyone tried DisplayLink with Ubuntu Touch?

The only thing I can find in the forum regarding DisplayLink is a thread from 2018. A lot may have changed since then.

Hello.
Since Ubuntu Touch is a true Linux operating system where the user has full control, it should also be possible to change settings from the terminal or bash script.
I'm primarily thinking of settings that you find in the GUI such as WiFi on/off, bluetooth, gps, screen rotation, hotspot, mobile data etc.
I know it is possible to control individual components as you would in a normal linux environment, but I want the buttons in the menus to also show that it is switched off or on.
Does anyone know if there is any documentation on this?

I also want information about which processes handle the various key components in the system. For example, which process listens to keys that are pressed on the physical buttons and whether you can enter your own actions?
