[tex-live] texdoc tries to launch X11

[Manuel Pégourié-Gonnard]

Hi,

Please discuss texdoc issues on the texdoc list (I'll keep you cc-ed if you
aren't subscribed). Besides it being easier for me, you'll usually get an answer
faster (for example I didn't notice the problem reported by Heiko before Phlipp
forwarded in to the texdoc list & github page).

If it is what I think, it probably started with version 0.61...

Texdoc tries to detect a running desktop environment to select the appropriate
viewer, and for xfce detection is needs to run xprop. I guess this is triggering
the X11 launch.

For now, a work-around may be to explicitly set all viewers (dvi, html, pdf, ps,
txt) either in the config file the environment. At least it could be used to
test my guess.

A better solution would require texdoc not to try getting the viewer settings
unless they are actually needed. This would probably be a big change in the
code, so it's probably not happening very soon...

Manuel.
