I upgraded from 2.1.4 to 2.2.0alpha2 (on ubuntu 15.10), and the PDF
output program changed from evince to okular.
In 2.1.4, the PDF output used evince (which I prefer). And when I run
2.1.4 now, it *still* uses evince (so this is probably not due to a
systemwide change).
On 2.2.0alpha2, the PDF output uses okular.
I tried to adjust Prefs/Output/PDF Command, but cannot seem to change
the program used for PDFs.
At first, the drop-down setting was blank (this was true in my settings
for both LyX versions). After selecting
synctex view -i $$n:0:$$t -o $$o -x "evince -i %{page+1} $$o"
(and applying/saving/restarting lyx), lyx still uses okular.
Anything I can try to switch back to evince?
Thanks!
(ps. I *love* the improvements to instant preview in 2.2.0 -- it almost
means I don't need a PDF viewer.)
