A little clarification, which I put together from a yesterday’s DC group chat:
DeltaTouch was originally made for ubports and lomiri devices, but since it’s now on Flathub, it should work on any x64 or arm64 Linux distributions that can run flatpaks, including Linux phones and Linux desktops.
It works even without touchscreen, with usual mouse only.
Seems like it uses way less resources, especially RAM (comparing to DC Electron desktop app).
UI can be a little more unpolished, and sometimes it likes to freeze-lag slightly.
Original DC desktop is more consistent and doesn’t really freeze, but also is more overall laggy. However, the minor hiccups are probably extremely fixable.
Was excited to discover this app on flathub. Installed on Librem 5 but it wouldn’t launch via app shortcut. Getting this error when launching via the terminal.
DeltaTouch 2.33.0
PureOS 11 Crimson
Phosh 0.34.0
Install from flathub.org, then try to launch with app shortcut.
That fixed it, thank you. Next issue I discovered is that it’s not allowing the camera to scan the QR code to add as second device. Librem 5 camera switch is enabled and working with regular camera app.
I was able to successfully set up DeltaTouch as a 2nd device by copying and pasting the backup QR code string from the clipboard.
Hmm there’s a similar issue on the Pinephone, but it works on other platforms. We’ll have to take a closer look, but to be honest, I’m not sure when we’ll get to it.
I think the issue was partly different on the Pinephone: as I recall trying to use the camera could crash the app. The airgappable non-peripheral camera is a Librem-Pinephone commonality that as I recall also caused OS problems.
If I remember right, taking a photo of the QR code and pasting it into the app works. Failing that, QtQR is a separate package which reads QR codes and gives the text; it works on mobiles. A bit kludgy, but you could used it to load contacts you’d photographed earlier into the app.
