examples/phosh-demo: init #352

zhaofengli · 2021-05-02T01:52:17Z

A very simple Phosh demo image with the full default GNOME app set, with gnome-terminal replaced by kgx. Not very exciting as many apps are broken on mobile 😕

Librem has a GTK patchset which you can apply with my overlay (not included).

Shouldn't most of this be part of a configuration option in upstream NixOS?

Relatedly, maybe, can this be done through a display manager?

Valid values:

https://source.puri.sm/Librem5/phosh/-/blob/643e3b37d3c03f3840402d018924f77780b774e6/src/mode-manager.c#L92

hostnamectl reads /etc/machine-info, but only if it cannot find the chassis type via another method such as SMBIOS (?) or the device tree.

Fortunately, https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux.git/commit/?h=sunxi/for-next&id=d900a1cd310de097fb94796ca575c118b2637b3b adds the chassis type for Pinephones. We just have to wait until the sunxi maintainers merge that into mainline.

Or we can fetchpatch it / add it as needed.

See NixOS/nixpkgs#153940 for a PR to add the Phosh systemd service.

I did try to add this to a config to get phosh running, but everything seems crashy. Not sure what I'm doing though... (phoc already crashes with some vague errors, and I really don't understand desktop managers well enough).

Have not tried this as-is though, maybe that works better.

examples/phosh-demo/configuration.nix

+      users.users.${defaultUserName} = {
+        isNormalUser = true;
+        # Numeric pin makes it **possible** to input on the lockscreen.
+        password = "1234";


How about users.users.<name>.hashedPassword instead?

It's not meant for actual use. This is meant more of an example configuration you can look at as a starting point.

Including this in your system configuration is foolish :).

We probably should make this more obvious in some way.

Had some clashes with user names and identifiers while upgrading profile from the xfce demo. Had to change user name to "nixos" and id to 1001 (in several places) to make it start.

i got an error:

error: The option `security.polkit.enable' has conflicting definition values:

puffnfresh · 2021-10-30T10:27:16Z

@genofire you can't cross-compile this, you have to use the same system (e.g. use aarch64 to compile for aarch64)

You try using QEMU via the binfmt wrapper:

https://nixos.wiki/wiki/NixOS_on_ARM#Compiling_through_QEMU

And then hack up the config to override the system:

nixpkgs.localSystem = { system = "aarch64-linux"; };

This works for me to compile the original demo.

mhuesch · 2021-11-15T11:27:46Z

in case anyone needs a bit of help adapting this into an example config (I did), I have a demo repo which builds for pinephone: https://github.com/mhuesch/pinephone-mobile-nixos-flake-example

all credit for actual implementation due to @zhaofengli & the mobile-nixos contributors 🙂 🙇

genofire · 2022-01-15T09:52:26Z

It works on my pinephone, good work.
But the virtuelle keyboard is "hidden" behind Accessibility settings,
also default Apps (Call, Chatty) ...

on first look i miss also feedbackd (but maybe i overseen it)

grwlf · 2022-01-26T16:33:53Z

I tested it briefly, and it works. I think, this PR will lower the MobileNixos entry level significantly, from "space-high" to somewhere like "a hard quest" ;)

The one significant issue is the on-screen keyboard. I can't see it at all, had to plug the desktop keyboard in. Will try to figure out what is wrong with it.

Yeah, I should rebase and get this merged soon.

For the on-screen keyboard, you may need to toggle the docked mode in the quick settings.

Oops, accidentally added a stray commit. Fixed.

@zhaofengli you can drop a commit when rebasing. https://stackoverflow.com/a/37311746/2611995

Yes, I know and have dropped it. I had an extra commit on master (an old version of #452) and didn't notice when rebasing interactively.

zhaofengli · 2022-05-07T20:28:17Z

With NixOS/nixpkgs#153940 finally merged, it makes sense for that to be used instead of manually defining a service. Let's merge #468 instead.
