There's no such system-wide file. It's your file that's being used. LyX only stores the filename, and searches both the user- and system-directories for it. > 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): > File "/usr/share/lyx/scripts/prefs2prefs.py", line 202, in <module> > main(sys.argv) > File "/usr/share/lyx/scripts/prefs2prefs.py", line 167, in main > lines = read(source) > File "/usr/share/lyx/scripts/prefs2prefs.py", line 52, in read > lines = source.read().splitlines() or [''] > File "/usr/lib64/python2.7/codecs.py", line 314, in decode > (result, consumed) = self._buffer_decode(data, self.errors, final) > LookupError: unknown error handler name 'surrogateescape' > filetools.cpp (1221): Could not run file conversion script > prefs2prefs.py. > GuiApplication.cpp (3092): Unable to convert > /home/rshepard/.lyx/ui/classic.ui to format 4. > GuiApplication.cpp (3099): Unable to read UI file: > /home/rshepard/.lyx/ui/classic.ui Note how it is reading the local file. > FWIW, I have python3-3.7.4 installed and no longer use python2, but > keep it > on the system until the distribution drops it. I have recently seen a problem with 3.7.4 on my system, as well, so it could be related to that. > 1) How do I fix the inability of lyx to read prefs2prefs.py so I can > start the application? I think we are going to have to fix that. But, for now, I'd try using a new user directory and see if that works. If so, then copy over a few things from the old one, and see if it keeps working. > 2) How do I fix the inability of lyx to convert classic.ui to format 4? Same. Probably, you can just change classic.ui to format 4 manually and see if you get errors. > 3) Where can I set the default lyx window size (running Xfce4)? Use the -geometry argument. See lyx -help for info. > 4) What is done to have lyx use python3 rather than python2? I am not sure what happens in LyX now, but this is auto-detected. I'm not sure if it is user configurable what python gets used. Riki
