How do you run an X application, both in the remote case and the local case?

Because the phone is running Wayland, there is no built-in X support, like there was on the N900, however, there are ways of running X apps under Wayland. What are the options, and can we have one of them implemented on the Jolla? Preferably including the libs to compile X-based tarballs directly on the Jolla.

Just to make it clear, this is not a duplicate of the Question linked below. Actually, it is exactly the opposite!

There is a Mer repository which can be used: https://build.merproject.org/project/show/home:javispedro:xwayland

You can add the repository via commandline with:

ssu addrepo home_javispedro_xwayland http://repo.merproject.org/obs/home:/javispedro:/xwayland/sailfish_latest_armv7hl/
ssu er home_javispedro_xwayland

Then you can install xwayland with

pkcon refresh
pkcon install xorg-x11-server-xwayland

Now you should be able to start xwayland:

Xwayland -nolisten tcp :0 & 
export DISPLAY=:0.0 &

Xorg/X11 applications should now work.

An example screenshot (by the repo creator https://twitter.com/javispedro) : example screenshot

EDIT: I just tested it by editing /etc/sshd/sshd_config on my Linux box to support X11 forwarding. On the Jolla I issued:

ssh -X [USER]@[HOST]

I was able to successfully start a graphical application.

This is awesomely cool! I just had to comment, because an upvote simply didn't feel good enough!

Works for me too, but white background is drawn black which isn't a good color. Except in minimized mode or when I swipe a bit from either of the sides. And no input is recognized (as the page says).

Xwayland is not ready yet AFAIK so you probably can't.

Are there no other options? I believe there was a way of running X.org as a client under Wayland, and both Gnome and KDE are going to Wayland, with GTK and Qt respectively

00prometheus ( 2014-03-30 01:24:47 +0200 )edit

Xwayland is supposed to do that. X clients under wayland. And as i said it's not ready yet.

Technically you can compile it yourself and patch it and write all the code you need to get it to work but i doubt you want to go through all that.

Thanks for that clarification. Do you know anything about work on directly running toolkits remotely? Is that just a plain wrong Internet rumor I am promulgating?

00prometheus ( 2014-03-31 01:26:12 +0200 )edit

The only thing toolkit related i can think of -didn't have to do with wayland- was GTK apps running on html5 capable browsers (localy and remotely). GTK Broadway backend.

In theory you can use your jolla browser to have it render a GTK app running on another computer. How to do this i have no idea.

not ready for sailfish you mean as my debian runs xwayland

A port of Xwayland was done for weston/wayland on Arch Linux on the Raspberry Pi: http://archlinuxarm.org/packages, or fedodora rawhide ARMV7HL: http://www.rpmfind.net/linux/rpm2html/search.php?query=xorg-x11-server-Xwayland&submit=Search+...&system=&arch=armV7HL.

Maybe can you use one of those to compile a Xorg server to Wayland ... fedora is rpmbuild compliant.
