Screen share vnc/rdp/x11 ?

[mingodad]

For development would be nice if we could have a screen share setup for the PinePhone.

I've got a mine with Manjaro and I'm struggling to find a way to share the PinePhone screen/imput to my linux desktop, I've tried to find vnc/xrdp through the package manager but no luck.

Does someone managed to have a good setup for screen/input sharing ?

Hmm not got my phone yet but I've got something you could try not the best at the command line tho

Code:

ssh -R 6000:localhost:6001 <ip of phone>[/font][/size][/color]

export DISPLAY=localhost:1.0   

firefox.exe

Then if you run firefox or any X program it should show up locally


I should warn this code is untested and not sure if should use -L or -R

If you host is windows you need to install https://sourceforge.net/projects/xming/

Thank you for reply but no luck with this !
After search for a while I found that the xauth was missing but even after install it and initialize .Xauthority I can not connect:
====
ssh -v -X manjaro@10.42.0.223

this way above what i know but you don't need to mess xserver as the Xserver is running on your PC and your just telling firefox on the phone to connect to the server on your PC and not the one on your phone

I tested again with only "ssh -X manjaro@xx.xx.x.xxx" and I can run fltk test programs (I compiled fltk-1.4) but any other preinstalled programs like "firefox"  open on the phone screen instead on my desktop.

I also installed tigervnc and can connect but only got a black screen so far.

It's using Wayland not X, so forwarding X only works with applications that are using X by default. For the ones that can start with either display you may be able to coerce them into using X by setting an environment variable or two, but what you set depends on the toolkit the application is using, for example:
GDK_BACKEND=x11 firefox

I think for Qt it would be QT_QPA_PLATFORM=xcb but there may be something else too. I've not looked into it for other toolkits.
For desktop sharing you probably need something like gnome-remote-desktop - assuming it's compatible with phosh.
