/usr/libexec/openbox-xdg-autostart is not compatible with Python 3 Fixed for me by adding to src_prepare(): sed -i "s:python:python2:" data/autostart/openbox-xdg-autostart || die This and other suggestions for openbox scripts that require Python 2 at upstream bug: https://bugzilla.icculus.org/show_bug.cgi?id=5432 I do suggest adding an elog message that USE="python" is required to get xdg autostart, or even renaming the flag from python to xdg or similar. It took me quite a while to figure out that the default USE="-python" was the reason for my problem (spice-vdagent not starting), this bug was the easy bit.
I don't want to rename the python useflag but I guess I can improve the description in metadata.xml
I'm not sure updating the metadata is much of a help when this functionality is hiding behind one of the most widely used global USE flags described as: "Adds optional support/bindings for the Python language" It's not adding Python support but requiring a Python module as a dependency. I looked at the USE flags and saw nothing that looked relevant to xdg so wouldn't have queried the metadata. Eventually I went and read the ebuild. But a better named USE flag (for the functionality it is providing), a log message or even turning the USE flag on by default would have saved me time.
equery m openbox will tell you what 'python' means in this case. And since all xdg scripts require python to run, I think this a pretty reasonable choice. It is pretty common to run equery to understand what each flag does before trying to guess or reading the ebuild In any case this is irrelevant to this bug
