Watt is not a unit of energy, it’s a unit of power [Joules/second]. This definition doesn’t change between kinetic and electrical contexts.

Got it, I’ll try this tomorrow evening. Thanks again for your help so far!

I’m running a desktop with relatively new hardware. Amd 5900x CPU, AMD 7900 GRE GPU, 32 GB ram, plenty of space and good airflow for stable thermals.

The freeze is definitely at least frozen desktop and mouse/keyboard. I also tried changing terminal sessions after a freeze tonight and this had no effect, so it’s probably the whole system?

Good idea with playing sound, I will try this on my next boot.

Debian 12. When the freezing first started, I lied to myself saying it’ll self-correct with time. I’ve since lost track of which timeshift backup to use. I am a silly fool.

And there was no kernel update afaik.

It froze again tonight. Neither ctrl+alt+del spam nor trying to change terminal session worked unfortunately. Seems to be 100% locked up.

Thanks for the comment.

It froze again tonight, I tried ctr+alt+del spam and nadda, no response.

I have not tried changing tty ctrl+alt+fn, but I will in the next session. Same with REISUB (not sure what this is yet).

My first guess for root cause was a ram leak, but my system monitor shows little activity when these crashes/freezes occur. Not that this is a perfect method of ruling this out, but my resource usage doesn’t smell fishy at least.

Whole system freezes unfortunately. The only silver lining is that I know exactly what time the crash occurred, since my clock freezes too!

No red text from journalctl unfortunately. My last few sessions each end with different messages too. One is a KDE Connect warning, a few others echoing some commands I sent in the terminal, etc. No red errors.

The system freezes permanently, requiring a reboot.

I have an AMD GPU, and likely have OpenGL installed.

I’m an absolute Linux tard, so it’s hilarious to me trying to read and understand most of these comments
