QDeskreen discombobulation

I was hoping to try Deskreen (LXF278) with my Pi400, so that I can use an older computer as a display. It didn’t work for me at all. I did find the support pages of Deskreen’s GitHub at https://github.com/pavlobu/deskreen/issues/59 so confusing that I gave up! Can you advise how I can get this to work?

A I’ll start with a disclaimer: I don’t have access to a Pi400 so this was done on a plain old Pi 4. You don’t say which OS you have on the Pi, so I’ll assume it is the standard Raspberry Pi OS, the OS formerly known as Raspbian. The GitHub page you refer to is basically a discussion between people who have already got it working rather than a set of instructions for those who haven’t, but near the bottom of the page there is a link to an AppImage build for the Raspberry Pi.

An AppImage is an all-in-one software bundle; all dependencies and the executables should be contained in the one file, which you simply run. It is not the most efficient way of running software – the bundle probably contains duplicates of software you already have on your system – but it is a quick and easy way of using it. The AppImage on the main site is for x86 processors; make sure you get the Arm one from the GitHub link. Download it to your home
