Google Summer of Code - Gnome dom0 project

[Parthipan Ramesh]

Hello everyone!

I want to work on Qubes as my Google Summer of Code project. I'm a
computer science student at Saarland University. I am a Qubes user for
about a 5 years. I switched from Arch Linux where I used GNOME. I really
like the GNOME desktop project. Over the years I learned a lot about the
internals of Qubes.

I'd like to work on "GNOME support in dom0".

What I did so far?
- Built Qubes 4.1 from source and installed it on a test machine
- Learned buildstream (gnome build system)
- Built gnome

At the moment I'm getting familiar with Mutter (window manager of gnome)
so I can start working on the needed changes (colorful borders). I'm in
the planning/getting familiar with everything phase.

Is there anything else you guys would recommend me to look at? Any
resources?
Do I need to know anything about the GUI VM at the moment? I read the
blog post about the GUI VM.
Thank you very much!

Kind Regards,
Parthipan Ramesh

IIRC Mutter is programmable via JavaScript.  It should be doable to select a window border color by looking at the correct window manager hint and then telling Mutter to paint the border of a window a color that matches the WM hint.

I think you really want to read comments at https://github.com/QubesOS/qubes-issues/issues/1806
There were some initial attempts, so you may want to look at it for
ideas.

For the window decorations, I don't think that would matter at all. It
may slightly affect how menu is adjusted (some things that works out of
the box in dom0, won't be available in GUI VM directly - for example many of the
hardware settings like power management). But I don't think you need to
worry about it in practice.

Thank you! I'll look at that.

Hello Marek!

First thank you so far for all your work in Qubes!

Yes, I'll read through the github issue to get an idea about what has
been tried. It should speedup the process. Thank you.

Best,
Parthipan Ramesh
