Issue migrated from trac ticket # 1792

component: server | priority: major | resolution: needinfo

2018-03-25 15:35:42: xaviermerino created the issue

I have a Debian container that I have set up with the following packages for xpra dependencies.

sudo apt-get install -y python-pip build-essential libx11-dev \ 
libxtst-dev libxcomposite-dev libxdamage-dev libxkbfile-dev \
python-all-dev python-gobject-dev python-gtk2-dev cython xauth \
x11-xkb-utils xserver-xorg-video-dummy libx264-dev libvpx-dev \
python-lz4 python-lzo python-cryptography ethtool node-uglify \
brotli python-pygame python-netifaces python-pillow websockify \
python-websockify python-rencode python-opengl

sudo pip install --upgrade pip && sudo pip install pyopengl-accelerate pyyaml websocket-client

I then proceeded to compile xpra. It all proceeded fine. My Xorg is located in /usr/bin/Xorg and Xpra's /usr/local/etc/xpra/conf.d/55_server_x11.conf had

xvfb = /usr/lib/xorg/Xorg -noreset -novtswitch -nolisten tcp +extension GLX +extension RANDR +extension RENDER -auth $XAUTHORITY -logfile ${XPRA_LOG_DIR}/Xorg.${DISPLAY}.log -configdir ${XDG_RUNTIME_DIR}/xpra/xorg.conf.d/$PID -config /usr/local/etc/xpra/xorg.conf

So I changed it to:

xvfb = /usr/bin/Xorg -noreset -novtswitch -nolisten tcp +extension GLX +extension RANDR +extension RENDER -auth $XAUTHORITY -logfile ${XPRA_LOG_DIR}/Xorg.${DISPLAY}.log -configdir ${XDG_RUNTIME_DIR}/xpra/xorg.conf.d/$PID -config /usr/local/etc/xpra/xorg.conf

I try to start a new server inside the container.

xpra start --start-child="xterm" --daemon=no --pulseaudio=no --bind-tcp=0.0.0.0:10002 --start-via-proxy=no

And it gives me the following output:

2018-03-25 14:24:53,402 Warning: failed to write script file in '/run/user/1000/xpra':
2018-03-25 14:24:53,405  [Errno 2] No such file or directory: '/run/user/1000/xpra'

2018-03-25 14:25:03,705 closing tcp socket 0.0.0.0:10002

And then just when you think xpra is done some new text pops up at the console.

Do you have any clues as why this is not working?

I try to start a new server inside the container.
What container?

Warning: failed to write script file in '/run/user/1000/xpra':
Why is this directory missing? Maybe something to do with the container?

My Xorg is located in /usr/bin/Xorg and Xpra's /usr/local/etc/xpra/conf.d/55_server_x11.conf had ...
That's normal if you are running on Debian and not Raspbian, not sure at all you should be changing it.

/usr/bin/Xorg: did not provide a display number using displayfd
Did you increase the timeout?

So I decided to run this:
Xorg -logfile /tmp/Xlog%s -config /usr/local/etc/xpra/xorg.conf -displayfd 2
And it gave me this:
...
[config] failed to initialise udev
6
Not sure about the udev problem, but the fact that it printed "6" at the end means that the displayfd switch did work.

Maybe it is just taking too long to start?
Does xpra work if you specify the display number on the command line?

The directory /run/user/1000/ can't be used because xpra doesn't have permissions.

I am running a Debian container so I will keep the /usr/local/etc/xpra/conf.d/55_server_x11.conf as it came. This is:

xvfb = /usr/lib/xorg/Xorg -noreset -novtswitch -nolisten tcp +extension GLX +extension RANDR +extension RENDER -auth $XAUTHORITY -logfile ${XPRA_LOG_DIR}/Xorg.${DISPLAY}.log -configdir ${XDG_RUNTIME_DIR}/xpra/xorg.conf.d/$PID -config /usr/local/etc/xpra/xorg.conf

So I do:

sudo xpra start :9999 --start-child="xterm" --daemon=no --pulseaudio=no --bind-tcp=0.0.0.0:10002 --start-via-proxy=no

And I get back:

?

The directory /run/user/1000/ can't be used because xpra doesn't have permissions.
That's not right.
Your user should have write access to the XDG_RUNTIME_DIR.
For more information see XDG Base Directory Specification and #1129

Warning: running as root
Don't do that.

Current Operating System: Linux 4df8e92d2195 4.13.0-37-generic #42~16.04.1-Ubuntu SMP Wed Mar 7 16:03:28 UTC 2018 armv7l
Is that still running on arm???? If that's on Raspbian as per #1777, then maybe you do need the modified Xorg path as per #1777#comment:17.

[config] failed to initialise udev
This is unusual.

could not connect to X server on display ':9999' after 3 seconds
Maybe the server needs to wait longer?
Try r18849 and set XPRA_VFB_WAIT=20 xpra start ...
