Plasma Mobile on Librem 5

[buzzLightyear]

I tried installing Plasma Mobile with instructions on Install Plasma Mobile link. But it did not work.

Has anybody tried installing Plasma Mobile on Librem 5? Was the attempt successful?

[Sarcasmo220]

Interesting. I didn’t even know those instructions existed. I was planning to try out Plasma Mobile by installing postmarketOS.

I tried installing

Why Installing instead Testing?

@Sarcasmo220

I was planning to try out Plasma Mobile by installing postmarketOS.

I guess that Plasma Mobile will in Gnu Crimson.

Purism

The installation instruction at the Install Plasma Mobile are fine. I modified the deb Index of /debpm/ buster main to use bullseye.
The phone boots fine after the installation. But the Plasma Mobile GUI does not show up. The screen is blank. @dos, do you have any suggestions?

Try the instructions here to install Plasma Mobile: Librem 5 and KDE Plasma mobile - #30 by lgtmak

I’m just starting to experiment with PostmarketOS now. I tried install plasma-mobile and it didn’t manage to boot into the GUI, instead showing a console login. I couldn’t log on as the keyboard input only seemed to work 50% of the time, so didn’t manage to enter my password.

I tried gnome-mobile and that is working (though it is quite laggy). Anyone have luck getting plasma-mobile to install recently?

Will keep on trying. Going to try crymson with plasma-mobile first (Librem 5 and KDE Plasma mobile - #30 by lgtmak).

The librem5-flash-image script seems to be broken for me:

Traceback (most recent call last):
  File "/home/jack/Development/_external/librem5/librem5-flash-image/./scripts/librem5-flash-image", line 538, in <module>

I got it mostly working with Mobian with their March installer with LUKS + BTRFS, but couldn’t figure out how to get KDE Discover working/appearing. I have it working now via Mobian on top of the original Phosh (most recent installer with LUKS + BTRFS), after I resolved package dependency issues. I have only been using it as a tablet though, didn’t test the phone/sms.

I somehow ended up with Plasma Desktop Wayland + X11 installed as well, which probably helped get it working, but I want to remove these sometime soon, as the login screen is now too small

@theelectricwiz

The librem5-flash-image script seems to be broken for me

Use a recent version of Debian or its derivatives on a USB drive, then follow the instructions again:

Anyone currently running Crimson

@FranklyFlawless: This may be hard to believe but after leaving the L5 sit all night with no battery, I re-ran the script again this morning from my Debian Trixie PC (yesterday I had been using my KDE Neon install) and, yep, you guessed it. Worked like a charm! I appreciate all your help.

Anyone currently running Crimson

You do need a sufficiently up to date version of uuu and it is possible that the two computers have different versions.

Otherwise, use the thread I linked and the instructions I provided within it.

Hello,
I’ve followed the steps in the tutorial so far. I added

deb https://repo.kaidan.im/debpm/ buster main devkit

to /etc/apt/sources.list but apt update says

Err:5 Index of /debpm/ buster Release
404 Not Found [IP: …]
E: The depot »Index of /debpm/ buster Release« contains no release file.

What is the status of lgtmak’s solution?

My release is byzantium, not crimson. So is crimson the newer development version and purism is going to add plasma mobile support there?

And I update by changing byzantium to crimson in the sources.list, run

apt-get update
apt-get upgrade
reboot

ant then I can continue installing plasma mobile.?

[FranklyFlawless]

That documentation is very outdated. Amber is based on Buster, whereas Byzantium is based on Bullseye, so you will at least need to change the Debian codename in your entry:

deb https://repo.kaidan.im/debpm/ bullseye main devkit

[MitjaStachowiak]

Ok, I will try this. Upgrading to crimson didn’t work. The phone is not showing a keyboard for file system password on boot but says after a few seconds, that all attempts had failed. I need to reflash byzantium and try again.

[FranklyFlawless]

Upgrading from Byzantium to Crimson via apt sources is currently unsupported and will cause system instability.

[MitjaStachowiak]

Ok… I’ve added the line with bullseye to sources.list. apt update now gives me some warnings like

Loading of configuration file »devkit/binary-arm64/Packages« skipped, because the depot »https://repo.kaidan.im/debpm bullseye InRelease« does not contain the component »devkit«.

Should I proceed? Should I install crimson on another way (which?)?

[FranklyFlawless]

The very outdated documentation was for the Librem 5 development kit, so you will need to remove that from the entry:

deb https://repo.kaidan.im/debpm/ bullseye main

Plasma Mobile from Kaidan’s repository only has support up to Bullseye.

When I was thumbling around with mobian and phosh parallel to plasma I had a similar issue.

Have you tried to change the options behind the shutdown button? I was able to get it working by changing the login screen.

Both phosh and plasma at the same time had some quirks.
Mobian had version trixie.

[Pirate_Praveen]

Recently I installed plasma mobile with PostmarketOS stable branch. It booted into GUI fine, but it was not very stable. I was stuck in some settings screen with no way to exit the full screen. PostmarketOS phosh was fine, but then I was more comfortable with phosh on Mobian Bookworm, so using that currently. I had to downgrade to bookworm since trixie was too unstable (phone was powering off while connected to charger when kept for charging over night - this is fine in bookworm).

[MitjaStachowiak]

If I remember correctly, plasma mobile comes with a matrix client (While the nheko-version of phosh is very unusable). This is one important motivation for me to try plasma

[MitjaStachowiak]

Ok, I’ve tried to install Plasma Mobile with

deb https://repo.kaidan.im/debpm/ bullseye main

The installation works, but the login screen stays black after reboot. Via SSH I can see, that simplelogin and phosh were running. I disabled phosh and rebooted, but still no success. So I disabled simplelogin and enabled phosh again. Good news: Phosh still works then.

What am I missing?

[FranklyFlawless]

I suspect the very outdated instructions simply do not fully work with the provided repository, which is likely why @lgtmak provided instructions in a different topic.
