tree-wide: GNOME Desktop

[robertkirkman]

• Alternative build of [WIP] GNOME Shell #24585

• Fixes Package request: Gnome shell #10173

• How to use this build:

# it really doesn't work well with Zink+Turnip
export LIBGL_ALWAYS_SOFTWARE=1
termux-x11 -xstartup gnome-session

[robertkirkman]

Very good thank you I will add them and maybe I'll try to add more

[sabamdarif]

Working fine

[sabamdarif]

@robertkirkman can you check if just running dbus-daemon --system --fork works or not

[sabamdarif]

0102-no-system-bus.patch

@robertkirkman can you try this patch then launch with just termux-x11 :0 -xstartup gnome-session

[sabamdarif]

But it can't launch app

[robertkirkman]

@robertkirkman can you check if just running dbus-daemon --system --fork works or not

Yes with just dbus-daemon --system --fork it works

[robertkirkman]

0102-no-system-bus.patch

@robertkirkman can you try this patch then launch with just termux-x11 :0 -xstartup gnome-session

What does the patch do? I tried it, and for me it is still necessary to run dbus-daemon --system --fork when using it before running gnome-session otherwise it has the white error screen?

[robertkirkman]

But it can't launch app

If you have adreno make sure to use export LIBGL_ALWAYS_SOFTWARE=1 first because it has invisible windows for me if I use Zink+Turnip

i was just trying to run them without system bus 😅

[sabamdarif]

wait let me share a screen record of my device

[sabamdarif]

for some reason it decide to work when i was recording :- https://drive.google.com/file/d/1_qvUG7OH6-F_-2eLFKGSAucKbHPSjA91/view?usp=sharing

but in most of the case this is what was happening:- https://drive.google.com/file/d/19sPJdPRZh0aNUZHWNWEqMbS6u_pQUJPQ/view?usp=sharing

[robertkirkman]

I see, that's interesting that the patch works for that for you; for me when I tested that patch and then stopped all dbus-daemon processes and then used gnome-session, this happened:

which is the same as what I see when not using the patch and not having dbus-daemon --system

[robertkirkman]

I tried to work on version 49, but as we know, version 49 has a strong dependency on a dependency-based init system, with a default at Systemd and the option to implement additional backends, and currently the only additional backend widely known to have been implemented at this time is this one for OpenRC:

https://github.com/swagtoy/gnome-session-openrc

If someone else implements another backend in the future that can restore self-launching of GNOME, then I could progress more by copying that. (I assume the distro with the most maintainers likely to do that is FreeBSD)

I tried to figure out if there is a way to manually write out the commands which the init system needs to execute in order one by one for GNOME 49 to complete its launch sequence, but I haven't been able to yet unfortunately.

I think it might involve a combination of $PREFIX/libexec/gnome-session-service --session=x11, $PREFIX/libexec/gnome-session-ctl, and $PREFIX/libexec/gnome-session-init-worker with certain arguments in a certain order.

Something I might be able to try is wrapping those executables with scripts that log their activities with timestamps on a Systemd or OpenRC distro, then launch GNOME there, then check the log timestamps to construct a sequence of commands necessary to launch GNOME 49.

[robertkirkman]

Alpine Linux has moved forward with the rest of GNOME 49 except for gnome-session by making this patch on gnome-shell 49 that makes it backwards compatible with gnome-session 48.

https://gitlab.alpinelinux.org/alpine/aports/-/commit/349a5ed70ff9d89e5c6af01f31078cc9b59bb8e3

I could probably do that now, but if many other distros also do that, then I expect a community-maintained fork or patchset of gnome-session 48 to eventually emerge that I could copy to progress here.

@robertkirkman can we not do something like this so we don't have to do that extra dbus-daemon --system --fork step, we can just run termux-x11 :0 -xstartup gnome-session

[robertkirkman]

Yes it's a good idea I might add that, though, the hard part is that I would want to actually make sure that dbus-daemon --system is not actually running anymore before using rm $PREFIX/var/run/dbus/pid, because i am not sure how bad it would be if it is removed without killing the previous one.

[sabamdarif]

ok i will try to do that

[sabamdarif]

we can get the pid like this

$ cat "/data/data/com.termux/files/usr/var/run/dbus/pid"
$ 9208

what about this ?

[robertkirkman]

Yes that's good thank you I tested that and it's working

[23xvx]

Just asking but can you guys later make a tutorial on this installation and perhaps setup requirements because this looks really amazing to me. I want to try running this on my phone

[robertkirkman]

@23xvx hi,

I made this video of how to download PR artifacts, you would download this just like in this video except just make sure you are logged into GitHub so you can see the download URL, and click on this PR instead of the one in the video, everything else is the same, then after you install it just use this command:

LIBGL_ALWAYS_SOFTWARE=1 termux-x11 -xstartup gnome-session

artifacts.webm

it will open

Another quick question but is it normal for the desktop to be laggy/glitchy because sometimes it takes time to respond when opening an app or just switching to another window

Yes it's because it has software rendering and GNOME is probably not really going to work on android with hardware accelerated GPU connection. so the CPU performance is fine but the GPU performance is not going to be good.

[robertkirkman]

LIBGL_ALWAYS_SOFTWARE=1 makes it have software rendering even if you have turnip and zink,

if you have both turnip (mesa-vulkan-icd-freedreno package, not automatically installed) and zink (mesa package, you already have it installed), and also Adreno GPU (Qualcomm SoC device), you can remove LIBGL_ALWAYS_SOFTWARE=1 when starting GNOME just to see for yourself what happens but it doesn't look very good
