First impressions of PopOs Cosmic Desktop

 

Upgrading PopOs to Cosmic Desktop

Last week, I upgraded my standby laptop to PopOs Cosmic Desktop. PopOs from System76 is a customized Linux distribution based on Ubuntu. Their latest version is based around the Cosmic desktop, which promises better UI and performance.

Overall impression:
Not impressed with the RAM usage (or CPU) – esp when opening up a browser (Firefox or chrome). The below image shows results from htop command. I also tested with Xubuntu and Lubuntu.

I upgraded from the previous 20.10 version which EOLs very soon. I might do a clean install to check if the resource usage improves. Granted I am pushing a laptop with low specs (2 core Celeron N4000+ 4 GB LPDDR4).
 
When I posted the above screenshots and my comment on LowEndSpirit forum,  one of the users (rightfully) asked:

“Why would you go with GNOME with those specs (CPU and RAM)? That’s not even just GNOME, it’s GNOME + Pop!_OS’ theme layer.”

They went further on to ask:

“Did you consider?

  • Xfce: MX Linux, Linux Mint Xfce, Xubuntu, Linux Lite, SparkyLinux Xfce, Manjaro
  • MATE: Ubuntu MATE
  • LXQt: Lubuntu, SparkyLinux LXQt
  • Plasma: Q4OS.
    Not listing super lightweight distros” 

I concurred with their views

Upon installing  Xubuntu,  the performance did not change much. Lubuntu gave some different issues, including networking and VPN configuration. I used the 20.04 versions of both.

Upon completing my tests, my response was as follows: 

“Valid Questions. Like I mentioned, this is my standby machine, so I can take slight liberties. However, my personal preference is Debian/Ubuntu derivatives with XFCE or Ubuntu Mate. Gnome is not quite to my taste- in fact, I had the same RAM/CPU issues (very high usage) on Macbook Pro 15. I recall reading somewhere (do not have source right now) it is a legacy GNOME issue that has passed on over generations of distros. I could be mistaken there”

p.s: as I speak- the laptop has KDE Neon installed, so some sanity restored.
