Hi Alex, from the logs you provided, it looks like the NVIDIA driver was crashing it the previous instances, and that is not happening anymore since the last updates you applied; this is confirmed by the absence of kernel stack traces in the latest logs; that's great to hear.
Now, about the turn off/on trick, unfortunately there's nothing in the logs I can point to for this issue directly. There are a lot of error messages in the logs you provided and, as far as I can tell, are all about suspend/resume, no sleep, am I correct? Are you connected through HDMI, right? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2138592 Title: Periodic/random soft lockup leading to system freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2138592/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
