I'm migrating to a new server/workstation and now I FUBAR'd lyx so it does
not load.
While looking in preferences to see if I could set the default window size
there (for a 1250x1024 dpi monitor) I did not find an appropriate setting.
But I did see that the UI file was a system-wide one rather than
~/.lyx/ui/classic.ui.
In preferences I changed to that UI file and killed the lyx process. When I
tried to reload the application it failed:
LyXComm: Pipe /home/rshepard/.lyx/lyxpipe.in already exists.
If no other LyX program is active, please delete the pipe by hand and try again.
Traceback (most recent call last):

to format 4.
GuiApplication.cpp (3099): Unable to read UI file:
/home/rshepard/.lyx/ui/classic.ui
I deleted the lyxpipe.in and that had no effect on trying to start.
FWIW, I have python3-3.7.4 installed and no longer use python2, but keep it
on the system until the distribution drops it.
Four questions:
1) How do I fix the inability of lyx to read prefs2prefs.py so I can start
the application?
2) How do I fix the inability of lyx to convert classic.ui to format 4?
3) Where can I set the default lyx window size (running Xfce4)?
4) What is done to have lyx use python3 rather than python2?
(And, I still need to get the current document compiled to use US letter
size pages, not 6.5 x 9.5 custom pages.)
TIA,
Rich
