I have installed Ubuntu 20.04 alongside Windows 10 (dual boot). I did it by installing Ubuntu on a USB and then I installed Ubuntu from the USB. I have already done it for my old pc and, in that case, both the Operating Systems worked perfectly (was it just the begginner's luck?) ! In this latest case (my new pc), instead, Ubuntu is really slow and I do not understand why !

When I say that Ubuntu is slow, I mean that everything is slow: if I open the broswer web, if I open applications like RStudio, Spyder etc... If I do all these things too fast together, it crashes !

Is it maybe due to the characteristics of the pc ? What can I do to fix this issue ? I have also to say that I have installed also xubuntu (for a mistake... I did not remember how it happened). Also this fact could be a source of slowness ?

Below are the infromation about my pc:

  1. RAM: 4,00 GB (3,83 usable)
  2. CPU: Intel(R) Celeron(R) N4000 CPU @ 1.10GHz 1.10 GHz
  3. System type: 64-bit operating system x64-based processor
  4. Card name: Intel(R) UHD Graphics 600

Sorry if I am not very precise in the description but I do these things without a deep consciousness and knowledge.

Thank you in advance !

System "freezes" are often caused by running too many, too large programs and running out of available memory. Use free to see if you have swap space, read man mkswap swapon fstab to create some. Traditionally, swap space of 1.5 × RAM has been recommended, but YMMV. If you don't plan to hibernate your system, you can have less than 1.0 × RAM.

    For the older computer, I had the same RAM and it worked perfectly with the same amount of programs... But I will try as you suggest . – HelpNeederStudent May 26 '21 at 18:06
