What is this (help needed read info & tweaking)
Explain your situation clearly. With Zram enabled on Pop-OS, the normal swap is disabled, which suggests your RAM usage is happening in memory rather than on disk. You’re having trouble editing while the system is running, and you’re wondering if deleting the 4GB swap will free space for a bigger swap on your second NVMe drive. You also want to know if you can install Pop-OS from a USB stick and whether enabling ZSwap with Zram works together, along with the steps to do it.
Swap acts like an additional layer to your RAM storage. When your RAM fills up, your Linux operating system begins relying on this extra memory space, known as swap. Since your screenshot shows only 26.7% RAM usage, the system won’t need to access swap, preventing slowdowns that could occur if your NVMe drives lag behind real RAM. You can expand the swap space, but with 16GB of RAM it’s usually unnecessary unless you notice high memory consumption during hibernation. Many desktop environments, such as KDE Plasma, allow sessions to be saved and restored automatically after login. If you notice swap usage, it’s wise to close unnecessary applications to avoid performance issues. For more details on increasing swap space, see the links provided.
