MATLAB: Is MATLAB Help browser showing unformatted text on Linux (R2018b)
help browserMATLAB
In R2018b, when I bring up the Help browser, e.g. using
doc classdef
it brings up a window, but it's just unformatted text, and no graphics.
I'm on Ubuntu 18.04. It is fine on R2018a.

I was able to fix this problem on Ubuntu 18.04 LTS and Matlab R2018b. The following command, run from the system terminal, showed that the system was missing libgconf-2-4.
ldd ~/.matlab/R2018b/HtmlPanel/glnxa64/chromium/jxbrowser-chromium | grep -i found
Output shows missing shared library.
libgconf-2.so.4 => not found
Solution: Install libgconf-2-4 AND restart Matlab
sudo apt install libgconf-2-4
Thanks to Alexander Maye for pointing me at jxbrowser-chromium.
This is a bug in MATLAB R2017b (and later) that affects Ubuntu 17.04 (and later). Since the release of Ubuntu 17.04, the libgconf-2.so.4 library does not get installed unless it was already on the system prior to an upgrade. However, this library is needed by the Live Editor in order to run.
As a workaround, run the following command in the terminal to install the missing library:
