Hi,
I just wrote a PDF reader based on Chromium PDF engine.
It's pretty dummy, written in 30 minutes. But quite useful (at least for me) given the limitations of Document viewer, and that sturmreader is currently broken on noble.
I think it will greatly benefit from Qt6 upgrade, when it comes, because of improvement of the engine in chromium.
It is published in the openstore:

I've succeeded in opening the keyboard when editing text in signal-desktop !!!! 
I could do it reusing the work of @ChromiumOS-Guy in uWolf!
I can officially send signal messages from a native Ubuntu Touch app, without Waydroid! 
Even though for now it's not convenient , since keyboard hides the text area, and the enter button of the keyboard somehow does not trigger sending the message, and the "send" button in signal is hidden until you expend the editing area. But still very usable.
For now everything is messy, but I will try to make it available soon (I think it should be possible to do a click package, but I'm not sure yet)
Ps: Note that I could do it with Mobian version only for now.
Hi,
Just wanted to share that VLC 4 (not yet released) has an interface very close to VLC for Android.
I will be a very good candidate to port to Ubuntu Touch. The interface would probably be usable as such, but with few minimal patches to the interface it could probably be near perfect on the phone screen.
I don't have time to do that now, but probably later (possibly when release officially)
Hi,
Just wanted to mention that a nice and easy addition to Ubuntu touch would be wifi captive portal via RFC 8910 and RFC 8908.
It is actually very simple:
1- When you get a DHCP lease in the wifi interface look for option 114
2- If there is a URL in option 114 it's an API, just make a simple HTTP GET request on this URL (no parameters or header)
3- The result will be a json, if it contains "captive"="true" and has an "user-portal-url" field then we should just open this "user-portal-url" in the browser and it will allow the user to authenticate to the captive portal and use the wifi!
Really I think that's any easy addition, I may try to contribute this inside the OS when I have time.
Ps: Adding a simple script in /etc/dhcp/dhclient-exit-hooks.d/ to do that should do the trick I guess.
Hi,
Just wanted to mention that I contacted the in-development French identity mobile app, to ask them for interoperability, and remind them their duty to make sure public service is available for everybody, and that their role was not to enforce the choice of mobile OS of their citizens.
https://france-identite.gouv.fr/
Surprisingly I got a pretty open and positive reply, apologizing that their app was not compatible with my OS (Ubuntu Touch), and saying they shared the goal of interoperability, and would study that with the development team what was possible. I did not expect such a positive answer, although I don't know if anything concrete will get out of this.
As a side note I wonder why for this kind of app, with a real need of interoperability, they don't use more Qt, because from what I understand Qt allows to develop apps for Android, iOS, Windows, Mac, Linux desktop, Linux mobile (Ubuntu Touch, Sailfishos, Mobian, postMarketOs, pureOs, ect...), all at once, with only few custom things to go for each platform. Any thoughts on that?
Hi,
Today I just figured why not try:
sudo snap install signal-desktop
And I realize it just works! This is crazy. With this simple command I can link my device and see my chats. Well it is certainly not a responsive interface (but not terrible either, there's just the left menu coming in the way) and the keyboard does not show for now. But I can consult messages, and this is major.
It means:
1°) We can certainly create quite easily a version of Signal-Desktop that is adapted to mobile display (with few patches to the interface to make it responsive), and that we can get a full-fledge signal client on Ubtunu touch, that way.
2°) That Mir2.0 will certainly help with that.
Ps: I guess the first easy thing to make it usable as a consul-only stuff is adapt the scale, which I guess must be easily doable.
Anyway after all the investigations that I've made I'm extremely confident that we'll be able to have a fully responsive client based on Signal-Desktop landed in the openstore within few month. I see exactly how to make it perfectly adapted to the phone Interface like whatsweb. (Funny enough it is possible to use a modified version of the js script of whatsweb to make the interface responsive, because the interface has an extremely similar structure. )
It's not anymore a question of "if" but a question of "when". But there are few tedious tasks in the way, and I need to go little by little, because I can't dedicate all my time to this.
Of course I'm open to any offer for help and testing!
I've been able to recompile Signal-Desktop from source and apply my responsive script.
It is available in the Openstore alongside these other improvements:
-Fix startup from OpenStore
-Fix open url externaly
-Fix battery problem
-Fix double window problem
There still are some keyboard issues, it's probably the next thing I will work on.
First of, thank you so much for the development on Ubuntu Touch, it is becoming amazing!
I have a question about Wayland/Xmir apps (e.g uWolf, Signal-desktop, Snap apps) in the context of the upcoming Mir2.0
Will you consider implementing any of the following, to polish experience with Wayland apps:
Would you need/accept some help to do that?
Craziest thing:
The calls are partially working out of the box!!!!
Which means we can certainly get calls working one day!
@gpatel-fr said in French ID app interoperability.:
I was talking about the chat control that the French gov (among a majority of European countries) is supporting. I don't know where it is currently, there is still work to do for the paranoid mad guys. What is concerning is that it is supposed to be enforced by having the 'secure' OS controlling the applications at the behest of the err, benevolent, err, leaders.
But this thing was rejected, This is no longer relevant at this time:
From my understanding this french ID app is currently in early stages and is currently used by a small minority (Only 1 Million downloads in playstore, probably many downloaded just to test it, and don't really use it at the time)

@pparent Sure, I can complement your bug report. But do you have the same experience?
- Press power button
- Backlight powers up
- No image is coming up
Yes I've seen it a few times as you describe, but most of the times I had a freeze with still image while using the phone and using the interface. In that later case the phone stays still in the last image, and pressing the power button does not have any effect. So I guess what you describe can be the same bug except that it happens while the phone is suspended, so when you press the power button it remains frozen on a black screen.

So there may be a leak but it hardly seems a blocker on my phone - that is, my current use of the phone is that as soon as I have finished using an app, I close it, and each evening I shutdown the phone for the night. You may use your device very differently of course.
Yes I use to keep whatsweb always open to get notifications, and I rarely reboot the phone if it does not crash, except if I somehow run out of battery which happens rarely given the very good battery life of the phone
Those days I've not experimented any crash. I'm not sure why. The difference might be that during the Christmas celebration, I've shared and received and taken many pictures with messaging apps. But it might be something else. Because the leak that we have noticed seems to require too many imports to explain completely the problem.

I've upgraded my Volla (yggdrasil) yesterday from 20.04 OTA-11 to 24.04-1.1 stable. Since then I already had two times where the phone freezes/crashes.
Well thank you for reporting, maybe you can add your experience to the bug report, so that it is clear the bug is not specific to my phone:
One thing that I'm missing in the new site compared to the old one, as a developer, is to be able to have an overview of the stats of all your apps as once.
Comme j'ai mis dans la description de l'app pour cela il faut attendre que l'on passe à Qt6. Il faut être patient au niveau de l'upgrade systême, mais je pense qu'on peut maintenant l'espérer d'ici à quelques mois. Ensuite les messages fonctionneront bien!
En attendant tu peux utiliser le Morph Qt6 beta, Min browser, ou Chromium for Ut.

sudo sysctl vm.swappiness=10
It does not seem to have clear impact on swap loss when importing from camera. I will see if the crash still happens in normal use, with this option in the coming days.

I tried to repro on my FP5 without success, but of course there are many differences: other phone, more Ram (I have 8 Gb hence a swap of 4Gb) , I don't use Whatsapp or Signal so all the apps available to share in contentHub are files and messages. After a dozen of shared photos, zero swap, available memory in top goes down by one or two hundred of megabytes, then back up.
Thank's a lot but I not sure to see how you can do it with files apps (or maybe there are import features that I don't know about, but I really don't see where).
Just to make sure I was clear with messages it would be:
1-Open messages app
2-Go to a conversation and click the attachment icon, then image
3-In contentHUb select camera
4-Take your picture and validate
I will to some more tests tonight including swapiness.

Also do you see kswapd taking a lot of Cpu like in my top ?
No but I did not pay attention either, I will next time.
It's probably the same software and setup for all ports since it's not linked to Android.
But I would be very curious to know if the action that I mentioned previously is reproductible for other VP22 users and non-VP22 users: importing a picture with contentHub directly from camera app to Whatsweb (probably works with another app than whatsweb), does reduce progressively the amount of available swap, when done several times, without any clear reason.
Because on my side it does it reproductibly, it's probably not the only action that triggers that, and it kind of explain why I end up without swap.
@gpatel-fr said in VP22 Upgrade from 24.04-1.0 to 24.04-1.1 failed:
could you play a little more with 'top' using 'f' and 's' to sort by VIRT or RES to see what is growing exactly, the default sort (Cpu) not being of much use here. If signal-desktop is not the culprit in this case, it may be whatsweb for example.
If you look at the last top I posted I sorted with %MEM which is equivalent than sorted by RES. And there is seemingly no process that eats too much RAM. I've never seen in a top any processes consuming outrageous amount of RAM.
I've also done a df -h , to see if a ramfs could use too much space but I've seen nothing.
As you tell me that "the swap handling is not the 'classical' sort, it's the more advanced type of 'compressed Ram'", I wonder if the swap itself could be buggy?
@gpatel-fr said in VP22 Upgrade from 24.04-1.0 to 24.04-1.1 failed:
oh, the Ram eater !
Holmes, the game is afoot
Holmes would say that Signal-Desktop sure is an easy culprit but the easy culprit rarely is the real culprit! 
In this case Signal has an alibi: I've just been able to reproduce the bug, without starting signal-desktop since boot.
It can be done more or less reproducibility by playing with the camera, and importing pictures to Whatsweb directly from the camera app in contentHub a bunch of times, and recording videos.
But also a new clue arrives in the investigation, I've realized that actually if I give the system a lot of time, like 5 - 15 minutes, without rebooting it, it seems to end up recovering (at least sometime, I will see if it is reproductible), and after the recovery free swap recovers to more or less normal levels in top ( 1268 ) .
