I’m using an XPS 13 9350 with 16GB of RAM and the Intel Graphics 540. I am using Fedora KDE spin. When I am using computer, either randomly or when I start a program, my computer will slow down and quickly fully freeze. In this state, the only thing I can do is shut it down. Is there any way to make it so that a program is killed, or something else that doesn’t fully stop my system?
Slows down then freezes sure sounds like an out of memory situation, so to add to yours here they might actually want less swap. Sometimes you would rather hit the oom killer sooner instead of waiting on swap to fill.
Ideally login via SSH from another machine to figure out what is using the memory (hopefully the system is responsive enough for SSH), and if it is your critical programs causing the problem then you should consider a memory upgrade.
Seconded on less swap. It depends on if you’d prefer to have a process be killed (have less swap) or the system go unresponsive for a while and eventually (hopefully) come back (more swap).
Also if the swap is on a slow disk, try moving it to a faster one if possible.
