That is an older laptop. I run an even older HP laptop on Arch that still feels zippy, even compared to my gaming desktop pc. One thing to remember is POP_OS! is designed for newer computers as it is built by a company who sells them. There are known issues with POP_OS! and Mesa drivers. The Mesa driver might not be efficiently handling the graphical demands of the default POP_OS! desktop. I’m not suggesting to switch your distro, just keep in mind going forward that it is made for newer systems.
Some further troubleshooting you can try:
- Check for Driver Updates: Ensure the system is fully up-to-date by running
sudo apt update && sudo apt full-upgrade
in the terminal . - Use a system monitor tool like
htop
,btop
or the built-in system monitor to see if the CPU or RAM is maxing out when opening a program. - Check for Overheating: Check if the laptop feels unusually warm. This could indicate a need to clean the cooling vents and fan.
What you are experiencing is called a learning curve. Don’t let it get you angry, learn from it. NVIDIA is known to be problematic for Linux users (I have had my share of issues with my 2080 Ti) but once it is setup it is problem free. Librewolf is known to be one of the chunkier options, but 3gb really isn’t that much for modern systems (especially if you have 16 or 32gb of memory). I would personally take Librewolf’s privacy features over closed-source Vivaldi any day. Linux overall is much more efficient than Windows and I would bet that your system idle memory usage with nothing open is lower than it was with Windows.
