encodings
-default "de-references" all
to the available encoders?
pdf-printer
. Is that default picked up at runtime?
pulseaudio
I've set it to 'no'
. I understand that 'no' == False
, but should it look like the rest?
socket-dirs
. Did you touch that between 3.0.6-r25195-2
and 4.0-20200303r25480-1
? (I was stuck in xpra-bionic-stable for some reason).
I am leaving commands that I've modified myself below for reference
pings (used) = 3 <class 'int'> pings (default) = 5 <class 'int'> microphone (used) = 'disabled' <class 'str'> microphone (default) = 'off' <class 'str'> min-quality (used) = 20 <class 'int'> min-quality (default) = 30 <class 'int'> min-speed (used) = 50 <class 'int'> min-speed (default) = 30 <class 'int'> speaker (used) = 'disabled' <class 'str'> speaker (default) = 'on' <class 'str'> webcam (used) = 'no' <class 'str'> webcam (default) = 'auto' <class 'str'>
Would socket-dirs
block me from being able to take connections?

I assume encodings-default "de-references" all to the available encoders?
Yes.
Doing so as part of the showconfig
command is impossible since we don't know if the encodings are for running the client or the server. (as can be different)
I never set pdf-printer. Is that default picked up at runtime?
This one is special cased because it is very slow to probe. Looking into it.
pulseaudio I've set it to 'no'. I understand that 'no' == False, but should it look like the rest?
No, pulseaudio is a bool
, the others are strings that happen to support boolean values as well as strings. (ie: fakexinerama can take a path to the library)
I've never modified socket-dirs. Did you touch that between 3.0.6-r25195-2 and 4.0-20200303r25480-1? (..) Warning: failed to create socket directory '/run/1000/xpra'
It broke in r25404, fixed it in r25503.
Updated beta builds will be available shortly.
The viable workaround is to set XDG_RUNTIME_DIR
.

My guess is that you don't have cups-daemon
installed, so we don't find the pdf printer files.
Improvements:
cups-daemon
to the install-recommends, so it should be present with standard installs from now on
@stdedos: installing cups-daemon
should fix this problem, the other queries are answered above. Please close the ticket if that works for you.

I'd like to clarify that. So, it is a bool, because there is no reason to support more states (fine by me).
Do you / Would you cast that no
to False
, or is that undesirable?

- r25512 add
cups-daemon
to the install-recommends, so it should be present with standard installs from now on- r25511 if we don't find the printer definitions, leave the defaults alone (more likely to match the values in use than using a blank value)
@stdedos: installing

cups-daemon
is already installed :/
$ xpra --version xpra v4.0-r25505 $ dpkg --get-selections | grep cups-daemon cups-daemon install
I'll wait until r25511 lands somewhere if you don't mind.

Verified as fixed. xpra-inside-xpra rocks :-D
Do you / Would you cast that no to False, or is that undesirable?
You can't cast the value of the "xinerama" option to a boolean as the value might contain a path. (string) And then the code that uses the value would still have to do its own casting / parsing.
I'll wait until r25511 lands somewhere if you don't mind.
All the latest beta builds have those fixes, the v3.0 backport is in r25513.

Cast the pulseaudio=no value to pulseaudio=False
Cast the pulseaudio=no value to pulseaudio=False
DOH! Sorry.
I don't know why I was looking at fakexinerama
when you were clearly talking about pulseaudio
!
Anyway, that's fixed in r25542 (+r25543 fixup).
I forgot to mention that booleans can also be set to None
to mean 'undefined' / 'automatic'.
In the case of pulseaudio
, the only difference this makes is that a failure to start pulseaudio
will only print a warning if the pulseaudio
option is enabled explicitly.
showconfig
will now correctly show auto
as the value.
