Hi guys! I have a rather beefy machine. AMD Ryzen 7700, 32GB DDR5, GPU 7800XT 16GB, several NVME drives for OS, general data, games. And yet…after a while it becomes completely unresponsive. Mouse freezes, keyboard doesn’t key anything, and the screen gets completely frozen. Meanwhile the disk led gets full activity, almost constantly red. So…While this might be crazy pagination turning the system to a crawl (I have an 8GB swapfile), I want to be able to determine what’s going on. Is there a way I can check any log, or enable any kind of logging that would tell me what happened on the seconds before it became completely unresponsive? Who takes all my memory??
Normal situations where this happens:
Firefox open, multiple windows, lots of tabs. Maybe ~5-8GB of RAM.
Virtmanager running a Windows VM, running a work remote desktop…4GB of RAM
Steam…1GB of RAM
Thunderbird, Deluge, Telegram, Whatsapp…Not much more really.
This shouldn’t even come close to the RAM capacity of this machine. And yet…it really looks like it suffocates without memory. How can I check for issues?
you’re nowhere close to RAM exhaustion. I had similar mishaps on an all-AMD system a few gens back and it manifested itself as micro-stutters that occasionally grew to such manifestations. I think I remember it was fixed via a combination of kernel switches and progressively better performance as new versions of kernel and modules/drivers progressed.
no idea what KDE Neon is based on (Ubuntu LTS?), but I’m guessing you rock pretty old kernels and relatively modern hardware, which is a pain. also you don’t need a swapfile, use zram. or just switch to fedora or sumsuch that takes care of all them things for you.
