OK, this time it's fine Thanks to all Good evening Pulsar33

@flohack Even a little is more than me and a lot ^^ All i know about libertine is there lol

@br1 not as good as expected but I thank you anyway for the information. It seems I will have to change the type of communication, even if simple bidirectionnal UDP was cool. BR Pulsar33

@doniks snapshots are done and commented. I have now to explain with some words. Trying to do that tomorrow BR Pulsar33

@moem this picture was for @Lakotaubp because not possible to send in private, it seems Yes he has (well) done the job

@dobey Well, I'm currently discovering the Libertine usage and trying to compile, test, modify (if needed for convergence) some source code of my own. These source codes are on my Desktop PC running Linux MINT 19.3, in a Folder called Workbench and containing many sub-folders (one for each application that I developed and some for general functions reused by many of my applications). I use the Eclipse IDE to compile and debug all that since years ... It was simplest for me to copy some folders needed for CheckLog in the Documents folder and compile in place, then test. I'm not in the process of developing published code and I'm not used to create deb files. That said, if Libertine is a Desktop-like environnement, I don't see why there should be specific location to install excutable, icons and data. A sub-folder anywhere should work as well, no ? @dobey said : I'm not clear on what you mean by that, or what error you got, Since the beginning of this thread, I successively tried to launch my own GUI App (already validated on MINT) in its own window (not in the LXTerminal) and then create a launcher to be able to launch it from outside Libertine as every normal application. This means with an icon displayed in the drawer, a temporary splash-view displaying the Icon and the name of the application, then the application itself in its own window (in Windowed mode or Staged mode). I explained each step of what I discovered and list any unsolved questions, and fortunately any solution I found. At this time, there are some "strange" things for which I don't know if they are bugs or not. @dobey you suggested me to post an issue about the BT Keyboard for Libertine, so you are involved in this development. Maybe you can advise me about these points : libertine-container-manager exec and libertine-launch can't be used in a .desktop file located on the UBports side to launch a GUI App in Libertine. In the same way, these commands can't be used in the UBPorts Terminal. There are "chroot" or "DISPLAY" errors. Is this a bug ? On the opposite, the command "ubuntu-app-launch xenial_checklog_0.0" works but is not described in the Libertine Documentation (AFAIK). The issue 194 still open says libertine gui apps cannot run. This is not true (anymore if it was). Should it be closed ? When a desktop file is located in /home/phablet/.cache/libertine-container/xenial/rootfs/usr/share/applications/ and in /userdata/user-data/phablet/.cache/libertine-container/xenial/rootfs/usr/share/applications/ the launcher appearing in the drawer can start a GUI App located in some arbitrary sub-folder of ~/Documents but the icon located in the same sub-folder is not displayed, neither in the drawer, nor in the splash-view during the application loading time. Is this a bug ? Thank you for your opinion and suggestions BR Pulsar33

@kugiigi It is in UTTT also, along with launcher scaling.

@flohack said in RFCOMM TTY support non available: @pulsar33 we combine the final code that runs in your device out of a common part, our so-called "rootfs" and the Android adaption parts, that is: Kernel, device and vendor tree. Latter were not released by BR (and in turn by Mediatek) so that we could rebuild the kernel, yes, your assumption is true. Thats also the reason why it will be very hard to continue to support this hardware in the future. Can you give me a link with a explanation of the way these things are related to one another ? I have recently bought a Xiaomi 9T which has some "Not daily useable builds" for : Jolla Sailfish Ubuntu Touch Via Hybris and GSI ports somehow but I can't get either one of them to run so I want to know what the heck I am doing wrong... Flashing the Stock ROM (any version) and TWRP afterwards is no issue at all

@dobey Hum, No sure I understand everything but I will try to analyze your proposal ... and come back. Thank you. Pulsar33

Thanks. Will try that Have a nice day Pulsar33

@jezek : Hum, I don't know ... It seems to be scripts using rfcomm. bt-serial : Connects to a specific RFCOMM based service on a remote device and then creates a RFCOMM TTY device for it Not installed by default I think. So, a bit out of scope. Best regards Pulsar33

@hoh61 i have an m10 fhd ML002151 if you need to download UT firmware http://www.mibqyyo.com/en-download/categorias/aquaris-m10-fhd-ubuntu-edition/

Thank you for the advertisement. This is an old message and unfortunately, the first link is down but it was here only to explain what we did at the begining and did not work. I think the end of my post remains valid and give additionnal information related to this Hope this help Pulsar33
