Hello,
I'm struggling with the following problem : the documentation shows only a black screen, as you can see in the attached picture. I also noticed the same thing for the live editor, though I don't use it.
I've tried the following :
- Changing the renderer (source) :
com.mathworks.mlwidgets.html.HtmlComponentFactory.setDefaultType('HTMLRENDERER');
The documentation now displays OK but unformatted which is not very eye-candy. The Live Editor is still black.
- Installing missing library (source) :
Running,
ldd ~/.matlab/$MATLABVERSION/HtmlPanel/glnxa64/chromium/jxbrowser-chromium | grep -i found
I found that I was missing the deprecated libgconf library, that I installed. The return of the previous command is now empty but the problem is the same.
- Reverting to the default renderer :
com.mathworks.mlwidgets.html.HtmlComponentFactory.setDefaultType(' ');
The problem persists.
My computer is running Manjaro Linux with KDE. Java is installed through jre-openjdk (up to date, version 12.0.2). MATLAB version is R2019a.
I'd like to try a few things before trying the full reinstallation of MATLAB, so I'm all ears.
Cheers,
Guillaume

FOUND A FIX!!
the error that was actually thrown to me was:
/usr/local/MATLAB/R2019b/bin/glnxa64/jcef_helper: symbol lookup error: /usr/lib/libpango-1.0.so.0: undefined symbol: g_ptr_array_copy
I followed this reddit thread
these are the commands I used:
mkdir $Matlab_root/cefclient/sys/os/glnxa64/0_excluded
mv $Matlab_root/cefclient/sys/os/glnxa64/libg* $Matlab_root/cefclient/sys/os/glnxa64/0_excluded
I can now view my Documentation window and the Live scripts

This worked for me. Here's the link to the libselinux aur repo -> https://aur.archlinux.org/packages/libselinux/
