Ubuntu – My computer hang and it didn’t react even to the power button!


Help! I was surfing the web and listening to music on Ubuntu and suddenly it stopped reacting to anything. Mouse, power button, keyboard… It is still playing the same few second of music and I hear noisy work of HDD, and it reacts only to Fn+F7. What can I do?

You can try this: https://askubuntu.com/questions/671591/occasional-lockups-drmi915-hangcheck-elapsed-error-hangcheck-timer-elapsed. I had the same problem and those instructions saved me.

Especially if the freezing is sporadic/random and usually comes when you are browsing with several tabs open and also streaming videos.

I hope it helps.
