I have installed Ubuntu 20.04.3 LTS Desktop alongside Windows 10.
Ubuntu gets stuck momentarily at random. Are there any solutions to this problem?
I am not able to find any similar issues with anyone else on the forum. Probably I am not stating the issue correctly, in which case I apologise.
Thanks.
I have 16 GB RAM and yes, I have a dedicated graphics card - NVIDIA GeForce GTX 1050.
