Are there any plans to support something like termux-x11? #305

For termux there is project called termux-x11. It allows to show gui (for example xfce4) without using VNC etc. Project is available here: https://github.com/termux/termux-x11

Are there any plans to support something like this on nix-on-droid (or maybe it is already possible)?

Pull requests are welcome; I, personally, don't plan to work on this anytime soon.

It's actually possible to use termux-x11 out of the box if you add -listen tcp to your termux-x11 call. It's a bit absurd, but here's the step-by-step:

  1. In regular Termux, run termux-x11 :1 -listen tcp -xstartup "dbus-launch --exit-with-session i3" (replace i3 with whatever you want to use as desktop)
  2. Open nix-on-droid and run a gui app with DISPLAY=127.0.0.1:1. Example: nix-shell -p gedit, DISPLAY=127.0.0.1:1 gedit
  3. Open the termux-x11 Android app and you should see your GUI from nix.

You can automate this a little by writing the termux-x11 invocation to a script, and adding export DISPLAY=127.0.0.1:1 to your .bash_profile in nix-on-droid.

Still, it'd be cool if we could do termux-x11 without needing vanilla Termux installed at all. The termux-x11 tool appears to be very simple https://github.com/termux/termux-x11/blob/master/termux-x11 - if we can somehow expose /system/bin/app_process in nix-on-droid then it might "just work" :thinking:

I could modify termux-x11 so that it uses com.termux.nix.x11 instead of com.termux.x11 and that might work. Ideally we wouldn't have a duplicate app though.

With no TermuxApiReceiver to talk with and no ClipboardAPI to process the request it's not gonna work. This code would need to be added to our app somehow, plugin or not.

Ideally we wouldn't have a duplicate app though.

On one hand, there isn't much we've changed: bootstrap URL selection, some broken symlink resolution during login and some of the contact links.

On the other hand, coinstallability with Termux is kinda nice.

Now, if Termux had several "slots" to install different userspaces into from custom URLs...

I gave this a shot, but with i3 inside the nix-on-droid boundary:

I packaged up / forked from NixOS the a small subset of dbus (https://gist.github.com/harryaskham/15b4a13a98b12a469527e92b644589b7) and manually set:

Running with scrcpy I can get this nice picture-in-picture mode with my phone NoD streaming wirelessly to my desktop NixOS:

The top level nixGL is enough to get a HW-accelerated picom / alacritty running smoothly. Haven't found a browser that runs out the box yet :)
