Hello everyone,
I’m a new Manjaro User. I currently have an issue with Manjaro and Matlab. I want to use Matlab and after a while my system randomly freezes. At first I didn’t know what causes the issue but i realized it happend if I had Matlab opened with some figuers. The System will not respond on any keyboard input, the only thing i can do is to hard reset my computer. Do someone know why this issue happen? I already reinstalled the complete OS but nothing changes.
I use Matlab R2020b Update 2
System Info:
OS: Manjaro Linux x86_64

Kernel: 5.8.18-1-MANJARO
Kernel 5.8 is EOL: upgrade to 5.9 or 5.4 LTS
No swap means that if your memory is full, the system freezes as the Kernel OOM killer cannot swap anything. Create a swap file SQRT(RAM) <= swap <= 2*RAM if that would be the case.
Running a watch --interval=3 "free --human" is imperative to see if that’s the problem.
