invalid compressor(s) specified: lzo about xpra

[totaam]

Your configuration files are invalid and specify lzo as a compressor.
This compressor has been removed in v5.

To see where this comes from, try:

xpra showsetting compressors

---

xpra attach tcp:gtxr1.srv-local.mpi-dortmund.mpg.de:2001 --encoding=webp --speaker=disabled --opengl=yes --min-speed=0 --min-quality=0

• this syntax has been deprecated for years, use tcp://host:port/ instead
• --encoding=webp is a bad idea

The output is

Warning: invalid compressor(s) specified: lzo

However, I looked in the files /etc/xpra/xpra.conf etc but there are no compressors specified.

Thanks for syntax hint! I changed it :-)

Regarding encoding: Simply remove it?

[totaam]

However, I looked in the files...

grep -r compressors /etc/xpra

You have some outdated configuration files there, which can cause other problems too.

Regarding encoding: Simply remove it?

Yes, raise --min-speed or --min-quality as needed instead.

/etc/xpra/conf.d/10_network.conf:#compressors = all

It comes from here... simply delete the file?

Personally, I would figure out why you have an old configuration file installed rather than the one that comes with the package you have installed.
Perhaps you had made some changes to that file and the package manager decided not to overwrite them?

Installing the correct file from the package would be my preferred option, but deleting it would also work.

[thorstenwagner]

I thought that the reason is, that I installed an old xpra version first via the package manager. However, uninstalling it did not remove those old config files. I will simply try to delete them. Thank you a lot for the support! :-)
