Why isn’t Linux using more than 2.1 GB of RAM

Why isn't Linux using more than 2.1 GB of RAM. I don't think I have ever seen it use more.
My laptop
Intel i5 520M @ 2.40 GHz
dual core with HT
2 SODIMM
DDR3, 2 GB each
Speed 1067 MHz
4 GB total.
3.7 GB is available to the OS. Obviously, this laptop has an integrated Intel GPU.
I am running Kubuntu 18.04.3 LTS.
Firefox, Qt Creator, 6 Dolphin windows open, 2 console windows open, Kate open, 3 LibreOffice documents open,
Linux slows down too much since a lot of disk swapping is taking place.
KsysGuard shows that 2.1 GB of RAM is being used and 1.1 GB of swap file.
That doesn't make sense when 3.7 GB is installed in the system.
1.6 GB is still free. That's 43% free.
Am I the first guy who has noticed this? Is there something wrong with a RAM stick?
I could perhaps run memtest86.
It can't be, since it is using 2.1 GB and the GPU is using 256 MB.
