All correct: not having OpenGL installed is not a showstopper, it is
sub-optimal but definitely supported.

>From your previous log samples, I can only see a single line of warning
related to OpenGL:
"OpenGL support not enabled: No module named gdkgl"

On Debian systems, I believe that the package required for this is
Note however that in practice, you are likely to see more warnings and
not less!
(and that is despite a large amount of our code dedicated to trimming
down those annoying warnings)

The rest of your error messages are caused by the ssh connection
dropping from underneath us.
I agree that it isn't very pretty, but I'm not seeing anything like this
here. Maybe your version of xpra is outdated?
Anything older than 0.13 is no longer supported, your distribution
vendor may claim to support older versions, but I have never seen it
happen (as in, fixing known bugs).

FYI: the fix for this has been committed, and will be released in the
next 24 hours in our source release and binary packages (if you choose
to use those).

You're not posting the exact commands that you've used, but I've just
tested this repeatedly with:
xpra shadow ssh:localhost:0
And apart from just fixing a bug which prevented the following variant
from working properly (only in some cases):
xpra shadow ssh:localhost
I am not seeing the error that you refer to.
I have modified the code in trunk to provide more detailed error message
in this case.

I don't know which Ubuntu release you are running, or even which xpra
package you have installed..
