Consider using gnome/firefox less execution

Open lkocman opened this issue 3 years ago • 9 comments

using something like https://github.com/Hjdskes/cage for d-installer would eliminate the requirement to load gnome and firefox

Originally raised by Patrick Fitzgerald on the community call.

We welcome any help in creating:

  • An improved and more light-weight Live ISO.
  • A container that can run Wayland + a browser so we don't even need an ISO (see some experiments here)

Those are areas in which experts in operating systems, graphical environments, browsers and/or containers could help without needing to code D-Installer or YaST.

If you are reading this, please consider jumping in. :wink:

Communicated back to Patrick, just for tracking you could start with forking this project https://build.opensuse.org/package/show/YaST:Head:D-Installer/d-installer-live

Yeah, I play with cage and also sway ( which is in TW as opposed to cage ) and my main issue was that it failing with Leap15.X qemu. So can be tested only on TW host which I sadly do not have at hand. And question is how looks real hardware support ( especially on other archs like aarch64 ).

Perhaps we could get rid of Firefox completely by using an embedded Web browser (ie: Qt WebEngine)

Hi guys! I've been able to configure a live d-installer iso that uses cage with a qt-kiosk-browser: https://build.opensuse.org/package/show/home:jtorres:branches:YaST:Head:D-Installer/d-installer-live-test

This is a POC and many things should be improved, more specifically on cage side.

Cage is started as a systemd unit service. At this moment it can display the browser with cockpit-desktop, however, it has some issues with the cursor and a lot of lagging, it's not usable. I should research what is making this issue.

It can be attached to that cage instance a wayvnc daemon to show its display through VNC protocol. I've set up a systemd unit service for this too.

The qt-kiosk-browser is a minimal browser I've set up based on the Qt examples. It would make sense to see how to make it more minimal and avoid some Qt dependencies it has at the moment.

The next step I will do is drop all Xorg dependencies and see if the iso improves on light-weight.

Hi I just had a conversation with @lkocman about cockpit and this was brought up there. I was wondering has anyone looked into webkit2gtk(3/4) as a replacement for qt-kiosk-browser.

There are some caveats such as hardware acceleration on NVIDIA cards being broken and hence requiring WEBKIT_DISABLE_DMABUF_RENDERER to be set to 1, this causes some artifacts in rendering.

Yes, I have briefly looked into it. I really like its potential as a kiosk browser and the source code is small and understandable.

But I'm pretty clueless regarding the rendering artifacts. @joantolo may know more details.

in my experience the artifacts are effectively elements that were removed/updated ghosting and staying behind. Until the browser window was forcefully resized
