Issues when using on chromebook

[rudolphpienaar]

Summary

Latest version of packages install and seem to execute/startup fine on an x84_64 chromebook. However, running an xfce4-session never seems to draw on the display.

Background

On an ASUS Chromebook Vibe CX55 (with Android and Linux containers setup/working fine):

• installed termux
• installed termux-x11 artifacts from 20231006 build
• installed xfce4 and friends into termux
• installed a proot-distro install ubuntu and also within the proot installed xfce4 and ubuntu-gnome-desktop

Run 1 -- xfce4 within termux

export XDG_RUNTIME_DIR=$TMPDIR
pulseaudio --start --load="module-native-protocol-tcp auth-ip-acl=127.0.0.1 auth-anonymous=1" --exit-idle-time=1
cd $TMPDIR
TERMUX_X11_DEBUG=1 termux-x11 :0 > x11.log 2>&1

At this stage, x11.log seems fine with standard noise.

• using chromosUI ,start Termux-X11

App starts up and seems fine. Single blank/black window (I had previously configure settings to be fullscreen). Now, try xfce4:

env DISPLAY=:0 dbus-launch --exit-with-session xfce4-session

Nothing appears on the termux-x11 app, and termux console has seemingly standard messages:

• Try without dbus:

(note still complains about trying to get system bus)

Run 2 -- within proot

TL;DR results (unsurprisingly) are the same when running from within a proot:

proot-distro login ubuntu --shared-tmp --bind /dev/null:/proc/sys/kernel/cap_last_cap  -- /bin/bash -c 'export PULSE_SERVER=127.0.0.1 && export XDG_RUNTIME_DIR=$TMPDIR && su - rudolphpienaar -c "env DISPLAY=:0 xfce4-session"'

Thinking to try a different DE, I also installed gnome-desktop into the proot and tried with gnome-session.

Other notes:

The x11.log is rather verbose. I checked for anything with "error":

grep -i error x11.log

Unfortunately I do not have chromebook to test it.

Unfortunately I do not have chromebook to test it.

Well, if you have a lots of time, you can try to install FydeOS in VM. It has Android support, but not sure it's the same implementation as on ChromeOS.

[twaik]

It will not be same.

[twaik]

It runs fine on FydeOS with -legacy-drawing flag. @rudolphpienaar can you reproduce this with -legacy-drawing?

[twaik]

Also I can say that it does not report any errors during normal execution (without -legacy-drawing). But still does not draw image. I am not sure what exactly is causing this behaviour, how to detect it and how to fix it because according to logs everything is fine, nothing suspicious.

[twaik]

@rudolphpienaar ?

[twaik]

I succeed to use termux-x11 without -legacy-drawing on FydeOS and S24+ (via Samsung Remote Test Lab) after https://github.com/termux/termux-x11/commit/9e61493a1ffdd6a3caab8f6a9416c4b0311cb1cc. Probably that is fixed too. Issue will be closed in a week if no response or activity.

[twaik]

The issue is being closed due to the lack of activity. Also considering this to be fixed since it works fine on FydeOS and S24+ (which had the same issue according to the available description).
