Many issues are specific to xpra.
I am not sure yet.
xpra uses python2. Rather install the debian package

I searched for some options there, but I didn't find the proper sections. Thanks a lot for pointing me to them. Start/exit options are specially useful.
I found that this is reported in lots of logs and no one worries about it, so it is probably not relevant.
I just installed it for python2. It doesn't complain anymore.

This is great, and it helps me understand the scheme. I thought that all the applications would need to be started with xpra. It is cool to see how it can be transparent to the user if initialized properly.
I believe that
Since the host of Xvfb or Xdummy is now going to be a container, can I execute x11docker inside it (i.e. without docker client available)? Or do I need to do it manually?
By looking at the description of this flag:
Does this mean that I should skip explicitly creating the X server in the previous step? Or is it still preferred to use x11docker to create it, instead of letting xpra do it? Related to this, I don't see the difference between
It is not possible to connect an xpra client to an existing X server without an intermediate xpra server, is it?
This is the step I am more unsure about. I used to provide the X socket and

x11docker won't help you much in container. Though, it can set up an X server for you, but to reduce complexitiy, I recommend to do it yourself. Xpra wiki provides examples for

Thanks again! |
I thought you want to run x11docker inside the container. There it only can set up Xvfb, but nothing more.
Yes.
Assess yourself if that is an issue, i.e. whether the X server and its clients need protection. Cygwin provides Xvfb: https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fxorg-server-extra%2Fxorg-server-extra-1.18.4-1&grep=xvfb |
I thought that I did need to run x11docker where the X server is created, which is inside the container. But, if I can use x11docker to run the container without needing to execute it inside, that's even better.
But that will start a instance of vcxsrv, which is what I want to avoid in this use case. I want to have three options:
So, I'd like to rewrite the example above to: # Set user
# Check if some X server is already running. Otherwise, check is vcxsrv/xwin are installed (suggest it). Otherwise, select a display number.
# Share X socket with container.
# Run the container in the background, so that the shell can be used
# Collect in Xenv the parameters needed to start sibling containers: DISPLAY and XAUTHORY
# Print parameters required to connect from a client: user and port
read Xenv < <(x11docker -t --daemon [--port 127.0.0.1:8080] x11docker/xpra) &
# Allow to start containers which use the xpra server
# Share X socket, DISPLAY, XAUTHORITY...
env $Xenv x11docker ghdl/ext:gtk-ide bash -c "gtkwave"Does it make sense to you?
If the TCP port of the xpra server is open, they don't. But they should otherwise, isn't it?
Thanks. |

The xpra server works, and applications started in the same container can be used with a client on the host. However, other containers cannot use the X server.

If you don't want to have a dbus server, try:
Harmless, only used for virtualizing specialized input devices:
Since you are using MSYS2, you may be interested in installing xpra as an MSYS2 package rather than an EXE installer, this should be available upstream soon - download the PKGBUILD for now:
The difference is huge. If you have an X11 server available, use
Also in FAQ.
I would be very interested in hearing the results.
Always try to avoid doing things this way. |

@totaam, first off, thanks and congratulations. I had not realized that you are a maintainer/developer of xpra. That's such a great tool.
Frankly, I don't really know if I want it or not. I'd rather support it, in case it makes sense. I see that it can be useful for multiple applications running in the same container. But the use case here is xpra in a container and multiple applications in one or many different containers. Therefore, dbus might only make sense if I can actually share it. Hope @mviereck can provide some thoughts. Anyway, on the alpine based image, where I added cannot load dbus helper: No module named dbus

I'm not sure about it being the best alternative for my use case. I want to avoid installing dependencies on the host (besides docker and a shell). Hence, the portable client provided (which is 200MB) is a quite good solution. It is twice the size of vcxsrv, but it is ok, considering xpra does encoding/decoding. I had a look at the MSYS2 package and it relies on gtk3, which requires 355MB to be installed. The python2 variant requires However, I see that it might be useful in different contexts to have xpra available through MSYS2. E.g., to launch an xpra server on the windows host (without docker). So, if you want the package to be tested, I can give it a try.
I thought that

For the record, you can probably trim it down to less than 100MB by removing features you may not need: printing, audio, nvenc + numpy, opengl, etc
FYI: the mswindows EXE you downloaded is made using those same MSYS2 packages, we just trim it down and remove all the bits we don't actually need.

Indeed. The package is named
Do you mean by building the binaries myself or by removing dlls and executables from the portable tarball?
Is there any reference about how do you trim it down? It would be very interesting to have a 100MB client package which does not need all those deps. It is ok if those are just build dependencies, tho.

This is generally not what you want.
You should probably use a higher display number just to avoid any confusion (and also this warning message).

Either would work. Building yourself might be easier.
There is a bit of information scattered in various tickets.
Hmm. I've seen this before. I consider this to be a distro mis-packaging issue.

Sorry, I did mean the zipfile, not tarball. I have not used the installer.
Thanks.
Well, since alpine is not really designed for desktop apps, dbus might not be the most loved package...
It happens the same as with websockify. The packages are installed. You can see in https://github.com/alpinelinux/aports/blob/master/community/xpra/APKBUILD#L12 that both
That's because the base image is still based on Meanwhile, I'll update the package. |

@totaam Thank you for looking at this! Re: DBus:
You can add
VcXsrv is accessable only over IP but not with a unix socket. So Edit: |
That should have worked:
That's because it probably didn't check before and now it does.
This is unusual, but it should work. In fact, I'm pretty sure that it used to work. |
|
Re: xpra using VcXsrv Maybe the format IP:DISPLAY is not the issue. This The missing (or not recognized?) Composite extension is probably the reason why xpra fails. With x11docker could also add For the record: All VcXsrv options |
Some of the issues were actually my fault. I did not I now installed everything with I built the image again, including x11docker -it \

I think I won't in the end, because in my use case apps will be executed in different containers. However, I think it can be useful in other contexts where applications are installed on top of x11docker/xpra.
Even if dbus is not used in the end, does having the init system inside the container provide any benefit to x11docker?
I will. Thanks.
It did check it. However, I was using debian, not alpine: #117 (comment) I fixed it now by installing

@1138-4eb Are you still working on this? Otherwise we could close this and other related tickets for now and reopen them if they are of interest again. |
|
Feel free to re-open if this is of interest again. |
I'm sorry I missed this comment. I've been quite busy lately, so it is ok to close these issues for now. Nonetheless, I created a project with all of them (https://github.com/users/1138-4EB/projects/2), to make it is easier to come back later. |
Coming from #110, I tried the following on MSYS2:
First, start a GUI app on top of a xpra server inside a container and bind it to a TCP port:
Then, download an xpra client for windows (https://xpra.org/dists/windows/Xpra-Client-x86_64_2.4.3-r21365.zip). Either by opening
Xpra-Launcher.exeand clicking Connect or openingXpra.exedirectly, I can connet toroot@localhost:8086(without passowrd). The GUI shows as a new window in my desktop. Cool!This is the log of the server:
Bugs/issues:
cannot access python uinput module. Seems not to be relevanthtml server unavailable, cannot find websockify module. This is surprising because I did install it explicitly. Doesxprauser python2 instead of python3? Yes, xpra server requires python2. See https://packages.debian.org/buster/xpra and https://xpra.org/trac/wiki/Newsdbus-launch: not founddbus server errorif you do not have a dedicated dbus session for this xpra instance, use the 'notifications=no' optionFixed by adding the optionWarning: webcam forwarding is disabled, the virtual video directory '/sys/devices/virtual/video4linux' was not found, make sure that the 'v4l2loopback' kernel module is installed and loaded. found 0 virtual video devices for webcam forwardingFixed by adding --webcam=nofailed to load the mdns publisher. No module named avahi. either fix your installation or use the 'mdns=no' optionFixed by adding the optionpython netifaces package is missingFixed by installing it with pip (not pip3)The server can be stopped with:
This will close the GUI app, xpra and the xorg server.
However, if the GUI app is closed graphically, both xpra and xorg will keep running.
Open questions:
How does this fit with x11docker? As explained in the context of #110, I do not have a clear understanding about how is xpra used. According to https://xpra.org/trac/wiki/Usage/Docker and after the test above, I assume that:
So:
If the assumptions above are correct, the following example is not valid for my use case: https://github.com/mviereck/x11docker/wiki/Remote-access-with-SSH#ssh-with-xpra. It is not valid because it is assumed that the host OS in the server is GNU/Linux. So, command
x11docker --xvfb --display=30 --showenv x11docker/lxde pcmanfmwill try to create a dummy X server withxvfb, and connect a container to it. Unfortunately,xvfbis not available on MSYS2.I see two alternatives here:
--xvfbneeds to be removed. As a result, the GUI apps will be seen on the server.Xenv, but it is up to the user to start the xpra server on windows.--xvfbis used on windows, create the dummy X server in a sibling container. This would not require an X server on the host, since an xpra client would suffice (seexpra shadowat https://xpra.org/trac/wiki/Usage). Pseudocode:The second option is based on how
x11docker-guibehaves whenkaptainis not installed on the host. I find it to be a really neat solution.EDIT
I think that the comments above also apply to example https://github.com/mviereck/x11docker/wiki/Container-applications-running-in-Browser-with-HTML5#html5-with-xpra. I.e.,
xvfbis required on the host.Furthermore, I think that these pages describe a similar procedure:
