Htop shows swap space always empty

I am very new to Rocky Linux. I am looking for a stable Linux distro to work with my javascript development.
I am pretty happy with the Rocky Linux performance. I am not able to understand what is causing a sudden freeze, then the user is logged out.

So HTOP shows 16/32 GB of RAM consumed at a given moment in the development environment. But Swap remains always empty no matter how much sappiness i increase/decrease

Which version of Rocky?
Your swapfile does not look like the default Rocky install.
It might be best to start with a vanilla Rocky and post findings based on that (as plain text).
It looks like you’ve got many processes with incremental pids.
It would also help if you explain what you’re trying to do.

Rocky Linux 9. Yes, I removed defaults. Because i was facing issues of freeze

The trouble is, the freeze might not be related to the defaults.

Try putting everything back to normal, and then check the logs at the exact time of the freeze. The freeze might only be in the GUI and the o/s is still running in the background, or it might be a genuine freeze where the o/s stopped completely.

Swap being empty is not a problem. Swap can be used perfectly fine either as a normal partition, or as is here as a file on the XFS partition. I do that a lot and don’t have freezing problems. Swap being empty means you haven’t used all your RAM for it to swap processes. The freeze sounds more likely to be GUI-related, maybe 3D stuff. Compiz used to be known for doing that quite a lot in certain circumstances with specific configuration options.

Could be graphics driver-related, but would need digging through the log files under /var/log as well as dmesg for a start.

Which logs should i share ? That’s what in my /var/log/

❯ cd /var/log
❯ ls
anaconda           dnf.librepo.log  messages              spooler
anydesk.trace      dnf.log          mongodb               sssd
audit              dnf.rpm.log      nvidia-installer.log  tallylog
boot.log           firewalld        private               wtmp
boot.log-20220831  gdm              qemu-ga               Xorg.0.log
btmp               hawkey.log       README                Xorg.0.log.old

I have installed nvidia drivers, removing nouveau. Screens do feels more sharp ! Used these tuts:

  1. Tutorial

  2. help for tutorial

Thanks a lot for advice!!

Which logs I need to look up ?

Thank you so much for helping !!!

When the problem occurs look in Xorg.0.log for potential problem and also run:


This could show something

Last two working days have been great!
I’ll post a review after a week. I think your advice worked :star_struck:
