Matlab Documentation window and Live Editor is a BLACK screen

I use the Matlab R2019b(installed from the official website) and initially faced the black screen issue the first time it was installed.

The left of the image is my Live Editor and the right is the blank documentation window.

I was initially able to resolve the problem by installing




from AUR.

After my recent system update on 29th August 2020, the problem has resurfaced and reinstalling these 2 packages does not help. I guess I am missing a few other packages after the recent update and am not sure how to proceed.

The new forum now does not let me attach a screenshot or link
I am unaware on how to visually show my issue now

check out
you can upload a screenshot there and post the link here without creating an account.

can you also please give a bit of hardware info by providing the output of inxi -c 5 -b

ok, i guess that is is similar to
can you see if it gives you an error if you launch it in the terminal?
(type matlab)

Yes ,those were the kind of blackscreens I got.

When I ran matlab in my terminal , I got this error:

/usr/local/MATLAB/R2019b/bin/glnxa64/jcef_helper: symbol lookup error: /usr/lib/ undefined symbol: g_ptr_array_copy

I found a fix in a reddit thread and shared it to the Matlab community as well. Here it is , for our Manjaro community:

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! Hope this helps others as well :slight_smile:
