Hello,
I tried again to enroll into the ML and I hope that now it works well..
Otherwise, I tried with the flag you pointed out (--dbus-control=no), and I can connect using xPra client. Hower, I was expecting to use the html flag to connect using the HTML5 client and it doesn’t work (attaching the logs underneath). As it seems, most of the modules used by xPra can’t be loaded even if they are installed (dbus, websockify, and all the others are installed). I also installed the python-dbus, but seems that the error messages haven’t changed at all….
Also, as I can see, the /var/run/xpra folder is not created, so that might be the problem….. May it be that the installation is not creating the folder properly?
xpra start --bind-tcp=0.0.0.0:14500 --html=on --no-daemon --start-child=xterm --dbus-control=no

Hi again,
I’m sorry but I’m not receiving any of your mails in my mailbox. I have to go to the ML archives an read the answers there.
When I meant it doesn’t work is that it throws exactly the same error. And I’m not using any funny or strange configuration. It’s just a plain Ubuntu 14.04 server installed with default configuration, just install everything, enable SSH, and install xPra using the remote winswitch repo. 0.15.10-1 works as expected, but any version after this, throws the errors that I sent in the previous message.
So procedure to reproduce:
1. Install Ubuntu Server x64 14.04 in VirtualBox (running in MacOS) or any server (I have already tried in both). Simple settings, just enabling SSH server to remote connect and no interface or anything needed. If you want you can install SSH manually later on yourself, but this doesn’t affect the result. No NFS, nothing strange, just a plain installation of ubuntu.
2. Update the packages and install xTerm:`sudo apt-get update && apt-get upgrade -y && apt-get install xterm`
3. Install xPra (via winswitch or deb packages):
3.1Follow the instructions in https://winswitch.org/downloads/debian-repository.html?dist_select=trusty for trusty (14.04).
3.2 I also tried the alternative alternative installing with the deb packages manually from http://xpra.org/dists/trusty/main/binary-amd64/ with dpkg and apt-get install -f (both procedures 3.1 and 3.2 result in the same error later on). I made sure to install websockify, python-xxhash, python-reencode, ffmpeg-xpra when installing deb packages manually. Usually I use the winswitch PPA repo as it’s much easier.
Xpra gets installed with version 1.0.3:
sturgelose at gilgamesh:~$ xpra --version
xpra v1.0.3-r15051
4. Add user ubuntu to Xpra group `sudo usermod -a -G Xpra ubuntu` to avoid problems.
5. Execute `xpra start --bind-tcp=0.0.0.0:14500 --start-child=xterm` (just start a screen with xterm). There is nothing running in port 14500. You can also try with different ports, and will result the same problems. Also tried with `--html=on` option with the HTML5 client, it will happen exactly the same. And I tried different computers as clients.
If the command in 5. is ran as default non root user (ubuntu user), which is part of the Xpra group (added in 4.), the server doesn’t start and the daemon ends (mostly the error I sent in previous messages):
2017-02-13 09:46:02,017 Error: failed to create socket '/home/ubuntu/.xpra/machine86ec8863-384b-4baf-af76-aadfbefd4400-0':

xpra initialization error:
failed to create socket /home/ubuntu/.xpra/machine86ec8863-384b-4baf-af76-aadfbefd4400-0
If run the command (5.) as root user (something I’d like to avoid doing), the socket connects, but then when connecting from the client, it says it can’t find bus package (and other packages), which is installed… still you can try to connect a client but the dbus error will kill the process.

2017-02-13 13:10:11,445 server error (error accepting new connection)
This happens with any xPra 1.X version. I tried downgrading Xpra to 0.15.10 with Ubuntu 14.04 and works like a charm. Also, try the whole same procedure in Ubuntu 16.04 and it works as expected (no errors nor warnings).
In the client I only have one screen (disconnected the second one and rebooted even). I tried with other computers as clients and it’s just the same. The problem is in the xPra server.
I attach as well an export of the server configuration done with xPra.
<server_xpra_config.zip>
I can’t provide more information from the session, because directly the session doesn’t start! So, there is nothing to do with the encoding or whatsoever, it’s just Xpra not loading any of its dependencies!
I’m really not doing anything strange, and I’m totally able to use xPra 1.0.3 in ubuntu 16.04, using exactly the same steps, or Xpra 0.15.10 in ubuntu 14.04. So, there is something wrong with 1.X versions.
I hope this time I have redacted everything properly and added all the details...

Hello,
As a small update, I’ve been trying with different versions of xPra, and seems that all the 1.X versions do not work with Ubuntu 14.04 LTS. The latest version compatible with ubuntu 14.04 is 0.15.10-1 of Xpra.

Hi,
I’m sending it back to this mail, because seems I got a migration in my inbox and I didn’t receive the answer back (no worries, I read it in the online mailman archive), plus I got a new mail address.
On the desktop size the answers helped a lot, and now I’ve been able to run it in Ubuntu 16.04 after uninstalling VirtualBox additions and configuring my screen size.
However, I’ve tried to repeat the same process in Ubuntu 14.04, installing the latest version from WinSwitch repository and I’m having some troubles. As it seems it can’t create the socket, even if the .xpra folder gets set a 777 chmod and ubuntu is part of the Xpra group of users.
Errors are as it follows:

This is in a plain Ubuntu Server 14.04 and installing the latest version of xPra and with default configuration. I can run the command with sudo, but then, it complains that it misses the dbus, websockify and many other packages. If I try to install them by hand, it says they are already installed. So, I’m not sure what’s happening that xPra can’t detect the dependencies are already installed..
These two things were the ones crashing xPra previously as I see (now running in non-daemon mode seems to keep it running, but still can’t run it in HTML mode and I get lots of warnings)
Thanks!

Hello,
I’m trying to run a full desktop (I have tried KDE and Unity so far), in order to manage remotely a server.
At the moment I have this running as a VM in VirtualBox + VBox Addons in my computer (I hope it isn’t this interfering somehow…). I’ve been trying with Ubuntu 14.04, Ubuntu 16.04, Kubuntu 16.04 and CentOS 7. In all of them I’ve installed the latest release from the Winswitch repository (at the moment 1.0.2).
Anyways, whenever I start an xpra session, either if I start it from the client or HTML5 client, the transmitted desktop is a window that is much larger than my actual physical screen, and I can’t even resize it down. I’ve tried with the –desktop-scaling option, but it has no effect.
Also, I’ve tried to use different desktops (kde, gnome and unity), and to disconnect my physical second screen from my laptop. If I start a simple program as xterm, there are no problems, it’s the proper size. However, doing so with a desktop, it just won’t work.
Any suggestions on this? I’ve gone through all the xpra manual, but I might have overlooked a setting. Otherwise I don’t know if it can be a bug maybe…
Thanks a lot, and of course, thanks a lot for your great work and for this tool!
Best regards,
Erik berdonces
