Can I run Kubuntu
Can I run Kubuntu
You're considering moving to Linux because your current setup isn't working well. The old computer struggles with RAM and CPU usage even when idle, and Windows 10 32-bit is consuming a lot of resources. You're looking for something more efficient and stable, especially since you don’t have a GPU. I understand you're drawn to Ubuntu variants, but personally Kubuntu is your top choice. Posting your specs would be a good next step.
Based on the details you shared, your setup supports a 64-bit architecture. Please choose a 64-bit Linux distribution. While I wouldn't recommend a systemd-driven OS for what appears to be a basic P4 device, Devuan is a good alternative: https://devuan.org/ HTH!
Yes, it's possible. Kubuntu running in idle mode consumes around 400-500MB of RAM, leaving you with plenty of space for your applications. If it doesn't meet your needs, consider alternatives. Avoid sticking with 32-bit systems now, as most Linux distributions are phasing out support for them (the final Ubuntu release with 32-bit support was in 2018).
For someone just starting with Linux, it makes sense to continue using Kubuntu.
Devuan is Debian without systemd, straightforward. His hardware isn't really compatible with systemd, and systemd itself avoids legacy proc interfaces, especially those from older processors like the Pentium line. I've experienced this firsthand. I spent about two years installing Devuan on P4 machines in a refurbishment project at my previous job. My coworker had only a few years of MS experience, so he was new to Linux. I created a simplified installation guide, and he went through it multiple times, memorizing it. The project halted because of the pandemic, leading to my contract ending—something that would have happened regardless. At first, we used Linux Mint with systemd, which turned out to be a problem. I had to overhaul the whole process, set up a local Devuan repository without internet access, and install it manually. Productivity jumped dramatically. Instead of handling just two systems daily, we could manage ten or more each day. This change happened when my coworker was away due to health reasons.
