Full containerized OS using containers #4383
Comments
AFAIK, none of these are absolutely essential, though some applications may misbehave without dbus. Well done for figuring out how to get pulseaudio installed instead of pipewire. The initial resolution when starting a desktop session can be changed, ie:
The resolution is meant to be changed in response to changes to the browser window dimensions, not directly via BTW, you don't need to install these in a container:

I do need the audio. The problem is that even with a system dbus lqunched and pulseaudio installed instead of pipewire, audio isnt working at all :( For video, I will look into it, since it is absolutly ignoring my resolution settings and absolutly not doing dynamic scaling. That is why I tried to use xrandr to fix this issue without success |
So you're running as root inside the container? You may also want to set xpra/xpra/server/mixins/audio.py Line 35 in ba3d760 Since the xpra instance won't be interfering with another one since there aren't any.
What sort of scaling are you expecting it to do?
Oh, it just occurred to me that what you mean by "video" is the resolution of the virtual display. |
|
On a related note, is there an official xpra container available in any registry? |
Not yet, we should make one as this would be trivial. (based on Fedora) |
|
For the container side, I am running as a non-root user (the multiple warnings in the logs hint clearly in that direction, and I want my image to be as secure as possible). Therefore, I have given the permission to run dbus-daemon --syste command in the sudoers file for the container user. What I do is RUN as root, installed the aforementioned packages (xpra, xpra-html, pulseaudio ...), setup configuration files (i have copied the files found in I first tried to run "vanilla" ( modifications to the `05_features.conf, 20_audio.conf etc.), then started tinkering in the files to try to find my problem. I am now trying to run pulse audio with this config: And this overwride command: I am now rebuilding the image, adding an XDG_RUNTIME_DIR set to I will try to use more precise wording. I was indeed speaking about the virtual display resolution :) |
As per https://github.com/Xpra-org/xpra/wiki/Reporting-Bugs, this is an essential piece of information, not something to be gleaned later.
Does it work if everything runs as root, including xpra? |

(still_ on it, just a LOT of things going on, I will keep you posted when I can give you a more thorough description 🔸 ) Thank you for everything ! |
Describe the bug
I am currently trying to setup a full-containerized desktop (remote VM if you will) using xpra in the server-side. Audio is not working, and video is (for now at least) a mess (no full screen, stuck at 1280*720 50Hz, cursor not clicking were it is showing)
To Reproduce
wget -O /etc/yum.repos.d/xpra.repo https://raw.githubusercontent.com/Xpra-org/xpra/master/packaging/repos/Fedora/xpra.repoxpraandxpra-html5, firefox, @xfceNow this is where things get weird :
if I run
xpra start-desktop --start-child=xfce4-session --exit-with-children=yes --daemon=no --bind-tcp=0.0.0.0:14500and checks the logs,pulseaudiocomplains it is not finding thesystem-dbusand is failing to run:I supposed, based on this ticket (#3212) and an other one that is older where it was stated that 'pulseaudio' and all application where using their own "private" dbus to avoid messing with maybe currently running dbus.
Since we are in a container, I supposed that it needed at least the system dbus to be running. I therefore appended this command :
dbus-uuidgen > /var/lib/dbus/machine-id & dbus-daemon --system & && xpra start-desktop --start-child=xfce4-session --exit-with-children=yes --daemon=no --bind-tcp=0.0.0.0:14500to first run a system dbus on the container.After that,
pulseaudiostopped complaining about missing system dbus. It was complaining about missingmodule-x11but a simplednf install pulseaudio-module-x11fixed the error. Now I am stuck with :Any command, with XDR_RUNTIME_DIR manually set to a bunc of places (/run/xpra, /run/user/&{UID}/xpra, /tmp, /home/user/.xpra) fails with:
Funnly, cloning the xpra repo inside the containers and running the
pactl_impl.pyreturn sme informations:A lot (if not all) xfce plugins complains with errors of the like
GetManagedObjects() failed: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1For the video side, the xpra always starts with :
2024-10-11 14:11:52,645 setting dummy crtc and output 0 to:
2024-10-11 14:11:52,645 1280x1024 50Hz (339x271 mm, dpi=96)
2024-10-11 14:11:52,647 monitor 0 is 'VFB-0' 1280x1024
I tried using
dnf install xrandr && xrandr --output DUMMY0 --rate 60 --size 1920*1080or other variations, but the browser wont acknoledge this. In fact, all I want is the OS to dynamically adapt to the size of the browser window :(System Information (please complete the following information):
Additional context
If you could explain how things works that would help me so much. I understand what dbus is for, what pulseaudio is, what xpra is. But I have a hard time undnerstanding how everything talks to each other nicely :(
I did read A LOT of issues in this repo (Almost every issue, from issue that could be sort-of related to ones that dont even link remotely to my problem) but I am still unsure how things work and why I am running into those problems
