Hello. My Toshiba Satellite C655-S5307 (Intel Core i3) freezes up after being on for 15-20 minutes at which time I have to do a hard shutdown. Have not had system monitor open at the time to see what is happening. Is there a log or some way to find out what is causing the freeze-up? The fan starts to rev and then the mouse pointer stops responding.
Thank you.
Update: just ran it for 30 minutes and it was fine. Not sure what is happening.

You can get he log for the last boot with:journalctl -b-1 -p4 --no-pager
Also post the output of:inxi -Fazy
Considering your laptop uses Mobile Intel ® HD graphics with 64MB-1696MB dynamically allocated

High GPU usages → it gets hot → it cannot keep up → freeze.
journalctl --boot=-1
journalctl --boot=-1 --dmesg --grep="i915|radeon|amdgpu|nvidia|nouveau"

This tutorial was created because people are using a hard power off during freezes, so this will teach you how to turn off your computer when everything is frozen using softer means.
So whenever you see someone saying they had to “Power Off” or “Hard Reset” their system without doing a REISUB, please send them here!

Discourse – this forum’s engine – uses Markdown to format its posts, and removes “unnecessary” whitespace.
Terminal commands often produce output formatted so that they are better readable by the user, taking advantage of the monospaced font used.
Programming code often rely on indentation to make it more readable.
