Where?

You do not have any socket directories defined, this should not happen - r13859 improves the error (but the error will remain).

Since this is a non standard installation, please include the commands that you've used for installing and the commands that you've used for running the server. "xpra showconfig" wouldn't hurt either.

Im also using a Displaylink on /dev/fb1
The display device on dev/fb0 has a defective HDMI output -- non-repairable.

could Xvfb be causing this ? "-screen 0"

I thought this was seen before .... inticket #237 .. but was in different file.

OK, so the only change in your configuration from the defaults is that you don't have any "socket-dirs" defined.
When running "xpra showconfig" from a terminal, it should get printed out in orange to highlight it.
Please post the output of this command:

python -c "from xpra.platform.paths import get_socket_dirs;print(get_socket_dirs())"

This is what is used to generated "socket-dirs" in your default xpra config. (/etc/xpra/xpra.conf in v0.17.x).
I assume that you are on this version based on the file offsets, please update the ticket "version" attribute to match if that's the case.

I have edited comment:4 to use a code block so we can see what you typed, and clearly it's not what I had in comment:3.
Try using cut&paste instead, and make sure not to introduce newlines where there should not be any.

[kc7noa]

ok ... there were some changes in the formatting due to the email client ... moving forward.

odroid@odroid:~$ python -c "from xpra.platform.paths import get_socket_dirs;print(get_socket_dirs())"

[Antoine Martin]

kc7noa: so your get_socket_dirs() returns at least one socket directory ("~/.xpra"), as expected, and this is what should be in your /etc/xpra/xpra.conf. (please attach the file to this ticket)

[kc7noa]

contents of ...

odroid@odroid:/etc/xpra$ ls
xorg.conf
odroid@odroid:/etc/xpra$ 

there is no xpra.conf in /etc/xpra/

this is the first few lines of xorg.conf thats in /ext/xpra/

Should this file be named xpra.conf ?

[Antoine Martin]

Then your installation is borked, there should be an xpra.conf.
(xorg.conf is something else)

[kc7noa]

Wow . talk about tired .. i totally missed the fact-- that --- that is my Display config ... awful odd that its in /ect/xpra

Ill search whole drive for xpra.conf

[Antoine Martin]

It isn't odd, xpra ships an xorg.conf to use with wiki/Xdummy.
