@aimar wireless display is only supported via the Miracast protocol, and even so it may not work. Most Sony and Samsung monitors work and the Microsoft Miracast adapter is also sure to work.
While connected via wireless you can still surf the web, yes.

@MrT10001 Everything except cellullar seems to be working. But the previous owner also had issues with that with Android so I guess the hardware is broken. Fine for me since I only use Wifi.

But another problem now is that it didn't update to the latest Ubuntu touch version 193. Instead it downgraded to version 65 when I tried to update it via the os. Now nothing happens when I confirm the update to version 193.

So the readme is now updated with the accurate link to the install artifacts.

@johndoe
Thank you for your response! I believe I found one nearby, now 🙂

To complete this thread: I found a mouse that works like a charm: Rapoo Wireless Mouse MT750S 🙂
Okay, the lomiri bug that it only works fine in portrait mode is there, but I'm sure this will be fixed and this has nothing to do with the mouse itself.
So, thanks for all suggestions!

It's a really snappy and beautiful OS. Installed easily with the installer.

Browsers are a problem, as I've delineated a bit on another post in Support.

It would not update from r128 - I would click install and it would reboot to the recovery, but no update just a reboot option.

I had to wipe to factory, then it would update - now finally on r133. Fortunately I'd only installed a few apps and some minor configuration (dark mode, pinned apps, etc - nothing major.

Gonna give it a drive and see if the browsers, etc are better now.

Big thanks to the team, this is how a tablet OS should work.

EDIT: browser font is still weird - same in Jade Browser which I tried hoping it would work better but is probably based on the same source.

@MrT10001
Found it. It's the Sapot browser - don't know why.
Every other app gives sufficient sound, including the Morph browser.

"Man findet es immer da, wo man zuletzt sucht" - German saying, meaning "you always find it where you are looking last" (deepl).

Thanks again.

@rubencarneiro Thank you. I had changed my USB ports, USB cables, PC and so on and was stumped why this issue was occurring.

What I did see with the installer it went really, really quickly from fastboot to fastbootd and did the partition resize so quickly I just saw a flash on the screen. When I do it the manual way, it is quick but visible.
