Story is probably not new: using a (linux mobile) and everybody insists on using WhatsApp. I didn't care. But all activities the kids want to take part: .

I could try to evangelize all these football trainers, parents representatives at schools, parents of friends to use something that I'm able to use on my linux phone, but I can't: lack of energy, lack of time, lack of alternatives with the same feature set and stability.

Got out an old Sony Z1 running . Really old software. Got an so far unused SIM. I used Aurora Store from F-Droid to install WhatsApp from the Google Store on that Android. Registered to WhatsApp and it worked fine sending one test message that never arrived, because the other side didn't have my phone number in their contacts (I guess).

I installed as a server on my and put mautrix-whatsapp on its own system using the latest docker image following the documentation to get a minimum configuration running.

Yeah, works. Coupled WhatsApp on the Android Z1 with the bridge and send two test messages resulting in This account can no longer use WhatsApp due to spam shown on the device.

Is that most likely because of my 10+ years device + rooted + Magisk + fake google app store or is it something others are experiencing when trying to use the bridge with of the shelf devices, too?

My plan has been to run an independent phone number for WhatsApp on a device that only has contacts for WhatsApp in its phone book and make it available to family members through matrix.

Our participation in society relies in many aspects on the goodwill of a few monopolistic companies that we depend on. They write the rules which device (Android or iOS) and which software (only their own doing whatever they program it to do) we're supposed to use. They train the algorithms that can cut you off our participation.

I wouldn't care the least. I'd even smile when reading this thinking that it's exactly what people supporting companies like facebook/whatsapp deserve. But if the participation of my kids in society is at stake (and not my own which I well can organize without any messenger) it makes me sad.

Hey, thanks for the hint. I might try it again sometimes.

I've got one problem with thunderbird though that might be worse when running on a small computer like the :

It eats a lot of resources when there's are a lot of messages and folders on the imap server.

I wrote about it here.

That looks really great! Can't wait see it filled with life.

Meanwhile I'll share my solution. I'm an user since more than 30 years and I'm running my own email server since nearly the start of it.

The lack of having a reliable email client for my , my sons and in general bothered me a long time. didn't fit my needs and which I use on my desktop is no option for mobile devices, yet.

I ended up using to access a .


+ :

On an unencrypted registration SSID authorized a client through a portal page.

Then showed the client via dpsk (dynamic pre-shared key) provisioner login data for the encrypted SSID to connect to a network with internet access.

When the client connects to the unencrypted SSID it gets redirected to a portal to enter an email address (and possibly other data). Packetfence sends an email to a pre-configured address (owned by the sponsor) containing a link to approve the request for access.

The client waits on a portal html page for the sponsor to click the link. After the sponsor clicks the link to approve the request the clients web page reloads and shows the name of the encrypted SSID to connect to and a password for the connection.

Next step to accomplish: configure OpenWRT (hostapd) and Packetfence to allow the usage of the PSK to connect to the encrypted SSID.

BTW: Testing this I'm using to switch seamlessly between my notebook and my which I use as a test client for the wifi connection to the OpenWRT access point.

I'm not really a friend of being disturbed by notifications. My does only play sounds on SMS. Anyway...

What I've been thinking of especially since there is some work on the linux system of the Modem is if there wouldn't be a way to implement some service into the modem that does work even when the phone is in suspend mode.

This wouldn't solve the quest of having some service providint push notification, but it would solve the problem first that on the Librem5 and the Pinephone push notifications can't be received while the phone is suspended.

Another way to get this without having to hack on the modem would be to run a service that would actually voice call a phone when it's supposed to get a notification to wake it from suspend. This solution could be illegal in some jurisdication, because you signal something by a call that is not intended to be taken (and thereby charged).

After a wake-up from suspend by whatever dedicated method the linux system could do whatever would be good to get information about the event that initiated the wake-up call/[wake on modem data thingy].

From there whatever happens in linux could evolve. At first on the phone side I thought one would wait for the services defined by the user to connect to their servers and exchange informations. But this could also evolve into some protocol where the phone asks at the wake-up service for the reason for the wake-up and just make sure that it acts upon that information.

Maybe I misunderstood the whole situation and the whole problem, but it's nice that you started the discussion about this topic and I'd love to learn more about other ideas.

When doing the to share keyboard/mouse between my and my notebook on the Librem5 still the on-screen keyboard () keeps popping up and takes away part of the small screen.

This can be disabled through gsettings but doing so each time when I place the phone beside my notebook is tiresome.

So I recovered some old proof of concept I had made, tested it and packaged it:

switch-keyboard installs an rule that triggers when an external keyboard is connected and disables the osk. On disconnect it re-enables the osk and there is an entry for the menu included to just toggle the keyboard on and off just in case you're left without after disconnecting an external keyboard.

I'll give away so much: and notebook…

  • do not use extra software
  • do not have a data connection
  • it is a hardware solution
  • you could place any device in place of my Linux devices - windows, mac, android

Let's some more!

BTW: when the mouse/keyboard focus moves to the Librem5 which is connected to an usb-hub the screen activates nicely - no need to press a button.

and notebook sharing the same keyboard and mouse.

Moving the mouse over the edge of the screen into the direction of the other device brings the mouse focus to the other device - just like moving the mouse between displays in a dual screen setup.

The keyboard focus follows. It is like a kvm that is controlled by the mouse position.

Let's !


Just to mention it:

Updated a Sony Z3c running and upgraded a tablet running . Thanks for all the people who build these systems!

It took me about two hours to

  • get the backup on the Sony working in twrp with a sdcard
  • do full system backups
  • update CarbonROM manually, because the reboot into recovery doesn't work
  • getting a stable usb connection to the tablet by rotating ports, cables and orientations of the plugs
  • install a newer version of recovery.img on the tablet
    • needed to recap how this is done in Linux using heimdall
  • install the newer LineageOS via adb sideload

Looking back at the process I prefer much upgrading my and I need to get back to the idea of getting a to get rid of the dependency on the LineageOS tablet.

Sometimes listening isn't enough. Had to go into a video conference yesterday. Listening to music on my worked fine, but when I tried to get audio in the conference I remembered that my desktop is broken, because of this issue I wrote about.

I had to ask the other participants to wait, because I'd need to restart my desktop to get sound. Not funny if connected with people partly working on Apple devices.

time: the major problem at the time being in my use case seems to be and leaving sockets to pipewire- open.

I now run them using PULSE-SERVER=unix:/dev/null <program> and it seems they really do not connect to pipewire-pulse anymore and therefor can't leave its sockets open.

No sound in apps is o.k. - I can always run - if I need a page deliver sound.

Uhm, I'm listening to using my while on my at my desk. Why?

There's this bug letting pipewire-pulse fail, because too many connections are open.

I didn't find a way to have the play directly using pipewire.

Nice to have the same software stack on my mobile phone which now is connected to my usb speakers.

I'm migrating from a to a 3c. One OTP made it to my new Nitrokey and the rest still sits on the LibremKey. I updated my OS and installed the new utility which can't handle the LibremKey.

is still installed on my and while it is easy to use that way it is even easier from my desktop. Waypipe didn't work, but ssh librem5 NitrokeyAuthenticator -platform vnc opens an unprotected vnc port…

purism@pureos:~$ netstat -pnlt | grep Nitro (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp6 0 0 :::5900 :::* LISTEN 2019/NitrokeyAuthen

…which I can connect to to get an otp before migrating it to the new token.

And after disconnecting the ssh session the application keeps running and still can be connected to.

…after writing this I had to leave home, took my and the 3 on my keychain not expecting that it would work using pass-manager-compact just like this, but it did.

No adapter needed anymore, direct connect to the Librem5s usb-c :).

This feels strangely positive: you forget to put your on the charger in the evening. Next morning you get it out already with a spare battery in hand and find it running with 35% battery left.

This is such a huge improvement over the state of one year ago!

Serial connection via breakout board to my using a μArt serial-usb adapter.

While waiting for some press-fit headers I'm using poor mans press fit connection with nylon string.

μArt Crowd Supply

New use case:

  • Librem5 with a usb bluetooth dongle connected to usb-c
  • the usb adapter is exported to my network via
  • on my notebook I attach to the bluetooth adapter on the other end of our home over network
  • the virtual bluetooth adapter in my notebook is connected to a windows session running in kvm
  • the windows session contains software to view and configure the inverter of our photovoltaic modules

No need to sit on the floor in the room with that device to get a bluetooth connection.
