Crimson backports unofficial

tried it, gsettings and gtk commands, none of them working. The phosh seems to be stuck on the breeze icon and can’t detect any default apps. I am reflashing it to see if the same problem will happen again, Looks like codeberg set the throttle very low. I hit the 429 Error again, and have to wait awhile to upgrade again.

Update: I successfully installed it. So the difference is I have to use ssh from another device to do the dist-upgrade, the phone will not reboot during the networking manager configuration. And I also got the keyboard issue.

As far as I understand this behavior is typical for the new Phosh version. For which distro brightness control works better for you?

It’s not, it’s a mismatch between how the kernel behaves and what Phosh expects.

Hi All, I found another issue after installing it. Not sure if it is only me. The signal reception becomes very weak after installing the backports(the modemmanager did change to the 1.24 I think). because the installation, I can receive almost 3 bars under the basement, now I receive no signals.

Is there some patch to fix that?.. :folded_hands:

There’s I Challenge Thee (which is what I’m using). If you only building for the L5 and don’t care about anything else you can also return `PHOSH_BACKLIGHT_SCALE_NON_LINEAR` at Making sure you're not a bot! which should fix things too (but I haven’t tested that)

@galilley Question about backports updates. Once they have been applied via the apt terminal commands, will they be able to receive updates via the PureOS appstore as well, without having to drop to the terminal again?

Any future PureOS updates can conflict and break systems that use unofficial backports requiring you to fix stuff from terminal (not on purpose, it’s just not a tested or supported configuration).

Would that be an argument for eschewing updates applied via the PureOS store and regularly pulling them from the terminal via apt?

No, both methods come with the same risk.

In general most upcoming updates from PureOS received without problems, but @dos is right, nobody tested compatibility and you may be the first. In this case just write here and I will try to reproduce and fix any conflicts.

I could never get them to install from the store itself because of the unsigned repo problem. So I just always use sudo apt install/update/upgrade

Does anyone know if the beta is out, do I need to reflash the beta and reflash this backports? Thanks.

Feels like Librem5 on crimson alpha is still struggle to run gtk4 applications, not sure if a driver to support vulkan will eventually be out. the backports is nice but it is slower than gtk3 applications on crimson and byzamtium. this is the same on Mobian and Pmos that I have tried.

To my knowledge GTK4 relies on GLES3, which is not implemented yet. So I guess it stays that bad at least until GLES3 support is merged at some point.

What apps exactly work slower in backports with your experience?

I have no complains about the efforts towards to backports, I am enjoying it. But too many gnome core apps. I think they are build on gtk4 on the latest build? say Chatty, so slow to open a chat list, Animation stuck a second or two to load the conversations. Settings in chatty scroll is like 20fps compare to crimson original chatty, or the phone setting itself. Epiphany browser significantly slower and more sluggish than the old one that is on the crimson. I believe it is also just because is gtk4? It is not because of the backports, I tried Mobian, PmOS, they are all in the latest trixie apps, very sluggish on Liberty phone or L5 for those apps. The only thing that is still smooth is the Phosh itself, that I believe is still using gtk3.

Do you have the same amount of messages in Chatty in both systems?

Yes, I also l logged in to the matrix account to all the three OSs. Message amount is the similar. Epiphany browser setting page and scrolling is very laggy on the Mobian, Pmos and the back ports at the gnome 48-49 should be a good example to compare, crimson old one is smooth, I think it is a bit optimized.

From what I can see there’s GTK 4.19 is the backports, so it sure is going to be slow without taking additional measures as it will fallback to llvmpipe for rendering.
