SUMMARY

KDE neon installer (Calamares) allocates too small swap size (512MiB).
This sometimes causes system freeze.

I tried to install KDE neon on my physical machine (approx. 16GiB RAM) and virtual machine (4GiB RAM), and on both machines, the KDE neon installer allocated only 512MiB swap.
As widely known, 512MiB is too small for machines with 1GB+ RAM.
I discussed with carlosd on the webchat, and according to him, this is probably a misconfiguration of the calamares-settings.

STEPS TO REPRODUCE
1. Install KDE neon User Edition as usual
2. Open System Monitor and check the Total Swap Memory

OBSERVED RESULT

Total Swap Memory is 512MiB

EXPECTED RESULT

Total Swap Memory is the same as the physical memory size, or 4GB+
