<![CDATA[Signal UT: Signal-Desktop for Ubuntu Touch]]>Edit:
OpenStore

The following is the first post of the topic and is now outdated, read the latest posts for latest news

I'm building a new application for the openstore: Signal UT, which will be a custom version of signal-desktop for Ubuntu Touch. I've already succeeded to build an initial .click package of signal-desktop for Ubuntu Touch with basic tweaking to have a more acceptable scale and have the keyboard working. I've made scripts to build it automatically. Currently it is based on a reuse of the binaries from https://snapcraft.io/signal-desktop . But it does not require to use snap to work, it's a standalone click package (that we'll be able to publish openstore later).

https://github.com/pparent76/SignalUT

The app is currently not responsive (but I plan to work on it):

  • You can reduce the left menu to it's minimal size, as a temporary workaround
  • The keyboard will display on top of the textedit, so you won't see what you type
  • [EDIT] Somehow the "enter" and "back" buttons of the keyboard do not work after starting the app, but locking and unlocking the phone with Signal in foreground will solve it. (Probably and Xmir problem)
  • You should be able to fine tune zoom by plugin in a keyboard and use the shortcuts Ctrl+= & Ctrl+- (untested)

But it is already usable to consult messages, and send small messages (in a sub-optimal way)

What also works or kind of works:

  • Sending Audio messages, and listening to them (seems to work quite well)
  • Audio calls (and it's possible to see video from the other person but internal camera does not work), call quality untested.
  • Receiving non-Ut desktop notifications when keeping app in background (even when the phone is suspended)

WARNING: This is experimental, use at your own risks. The app currently needs to run unconfined. It contains binaries, that are free software but that I've not compiled personally (coming from snapcraft.io ) and that I have not checked. I do not take responsibility in case of any problem

Knowing that, if you want to be a tester, I'd be glad to get feedback from testers to know if it runs on other phones. So you will find a pre-built .click package here ( ONLY RUN ON NOBLE (24.04) ) :

Ok but could you record the screen when it fails to import the file with:

https://open-store.io/app/screenrecorder.ubports

because I fail to see what could be happening.

Can you tell which version of UT are you using, and post a video screenshot? because on all the phones that I own it works fine, so I would need to see visually whats happens on your phone.

You need to open file directly from Signal app, by clicking on the "+" in the bottom right hand corner of a chat, and then select the gallery app, to select the file to import.

It's true that there is currently something that should not be: Signal appears in the application grid in content Hub, as an option to export an image to, it should not, this does not work that way, only the other way around import the picture from the signal app. I will correct that in next revision.

It's not that there is only "system", it is that the combobox, ( or "<select>" in html ) does not work. i.e the element that allows you to chose, does not display well, but it is sadly the case in most XWayland apps, in UT and I can't do much about it right now.

I appreciate using the navigation, but when I click for example on " appearence" there is only "system" available. But thats normal, isn't it?

What do you mean "change the appearence"? It simply means that you can display and navigate properly in the menu in vertical mode, as shown in the screenshot.

The combobox still do not work, it is a problem with XWayland and Lomiri.

  • Make the left menu responsive
  • Fix a problem with uploading a document other than image (contentHub)

Note: no Signal-Desktop version bump for this revision, because building broke with my current scripts for 8.4.0 and 8.5.0, I'll have to look into it later.

Don't hesitate to tell me if everything works well for you.

I had SignalUT working okay but then had other issues (with primary Molly, Waydroid) causing me to uninstall (click trash icon in OpenStore) and reinstall several times.

Now, it seems SignalUT won't start (it just hangs indefinitely). I'd like to cleanly uninstall, reinstall and then link to my (now working) Molly Foss within Waydroid.

Is there a more brute force method to cleanly uninstall everything (than trash can icon in OpenStore)? Thanks in advance for your thoughts and suggestions.

Use UT Tweak Tool, then clear all 3 data locations from that.

@danfro said:

I couldn't reboot with the power button since that was somehow blocked

I really don't think this can have anything to do with running Signal UT, including the patch I've shared above. I don't see how the app could have an impact on the effect of your power button. Especially because it's confined. 😉

@danfro said:

I can't close it, when swiping into the drawer, it becomes a transparent window which I can't swipe to close

I see that happening from time to time, including with other apps. I think it's more a Lomiri bug. Anyway you can just start another time the app, and kill the launcher indicator, it should kill the remaining transparent window.

yes, the app now opens, but...

  • I can't close it, when swiping into the drawer, it becomes a transparent window which I can't swipe to close
  • I couldn't reboot with the power button since that was somehow blocked

I hope that makes some sense to you.
