Hello and welcome, good day. I’m reaching out to discuss my current project—a fresh Linux installation on a notebook with 4 gigabytes of RAM. Right now I’m in the middle of setting up a ThinkPad X220 with ample memory. I plan to add more RAM later during the holiday season. Regarding your questions: swapping is a standard practice during installation, providing extra virtual memory when RAM is low. It can help avoid crashes and ensure the process finishes smoothly. Many modern Linux distros, such as MX, Debian, or even Arch, usually create a swap file by default rather than using a dedicated partition. Both approaches serve the same goal. After the initial setup, adding swap afterward is also an option. Please let me know if you have any specific procedures in mind! Looking forward to your response. Best regards.
If you are using an SSD, especially cheap one - then none. If not, then "twice the RAM" was once a rule of thumb
Sure, this role involves around 8 gigabytes of work. Keep in mind you might be able to switch on or off the swap file later if memory runs low—something I use on some machines with long uptime, since certain processes can affect how memory is managed. This shouldn’t be a big problem on laptops. Also, allocating at least 4 gigabytes to a swap partition can simplify hibernate setup; it really depends on your needs, but the idea of sleeping while closed and hibernating later is a solid feature. If you’re concerned about your SSD, you have the flexibility to control this as well.
Are you requiring hibernation? If yes, aim for at least the same amount of RAM, such as 4 GB in your situation. Otherwise, there isn't a strict requirement. The common guideline of doubling RAM has lost its relevance over time and shouldn't be relied upon. In reality, 4 GB is quite low for a current operating system; depending on your desktop setup and applications, the system might need to switch memory pages. I recommend a minimum of 4 GB, but once swapping begins—especially without a solid-state drive—it won’t guarantee smooth performance. Even with an SSD, responsiveness may suffer unless you have sufficient memory. Possibly more is needed, maybe 8 GB, not because of the doubling rule, but due to limited system RAM. Personally, I don’t usually follow this advice, yet I always create a swap partition. It’s possible that if you skip specifying a swap file, the installer will choose a swap file instead. You might want to test in a virtual machine to check default settings. Yes, swap files have existed for a long time, so it's not a modern concept. Previously, resuming from hibernation with a swap file could be problematic, but today it usually works fine. The advantage of a partition is that it functions directly at the disk level, avoiding filesystem complications and ensuring the swap area stays continuous—though this can be more challenging on HDDs. Modern file systems can treat swap files as special, and tools like "mkswap --file" handle much of the work. In short, there shouldn’t be a major difference. I favor partitions for simplicity, but if you don’t use hibernation, a swap file is a good alternative. You can start with 4 GB and expand if needed. Also, consider zram (compressed RAM), which many distros include by default—this reserves part of your RAM as compressed memory, helping reduce swapping even further. Check your distribution’s documentation; for example, Arch provides guides on swap and zram. Overall, adjust based on your needs and performance tests.
