Original GitHub issue: https://github.com/netblue30/firejail/issues/827

the new version of xpra, available in arch linux, loads very slowly (10 seconds for) and shows some confusing errors.

among other things it says:

No module named pyopenc
OpenGL support is missing:
cannot import name gdkgl

Error: no encryption libraries could be loaded
pycrypto is not available: No module named Crypto
python-cryptography is not available: No module named cryptography
Warning: zlib is the only compressor enabled
install and enable lzo or lz4 support for better performance

however all the mentioned packages are available and enabled on my system

Is this only within firejail or does this also happen if you launch xpra by itself?

It seems this is related to firejail.
Using it normally there are no such errors and it starts fine

For installing Xpra on Arch I have a description here: https://firejail.wordpress.com/documentation-2/x11-guide/#arch

Looking at the code, we first start the server:

$ xpra start $DISPLAY --no-daemon

Then, we start the client:

$ xpra  --title="firejail x11 sandbox" attach $DISPLAY
