How Can I Stop My Laptop from Freezing Due to Out-of-Memory Issues?

From your logs, it looks like systemd-oomd didn’t actually kill any processes, so it may not be the direct cause of your freezing issues. Instead, the OOM killer is triggered when your system is low on memory. You're running Ubuntu 24.04, which uses newer GNOME, so make sure you're checking the correct logs. You can see what processes have been killed with this command: `dmesg -T | egrep -i 'killed process'`. Also, if you don’t really need the OOM killer for a desktop setup, you could disable it by running `sudo systemctl disable --now systemd-oomd`.

It sounds like your system is running out of resources when you try to open Steam and other apps. You might want to increase your swap space to give your system more breathing room. Even though 8GB of RAM is decent for everyday tasks, gaming can be quite demanding. Consider adding more RAM if you're planning to game frequently! You can keep an eye on memory usage by running this command in the terminal: `watch free -m`. That'll help you monitor how much memory you're using in real time.

While tools like GPT can offer some basic insights, they might not always hit the mark. To really understand what's going on, you need to examine your OOM logs closely. The systemd logs you shared aren't everything you need. Make sure to check if your OOM killer is working correctly and analyze the output more thoroughly to identify what’s actually causing the freezes.
