I added the prevboot.txt file at attachment. I realized in logs that there are some lines about cpu's execution like that:
May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU1: Core temperature above threshold, cpu clock throttled (total events = 43) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU5: Core temperature above threshold, cpu clock throttled (total events = 43) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU7: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU2: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU0: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU3: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU4: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU6: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU5: Package temperature above threshold, cpu clock throttled (total events = 526) May 20 13:17:14 TUBITAK-HASANFSIMSEK3 kernel: CPU1: Package temperature above threshold, cpu clock throttled (total events = 526) So when this freezes carry out, my laptop's fan noice increases dramatically and is going to explode. When I press the shutdown physical button and reboot the system, everything is being fine. But until the next freeze... Maybe 4 days later, or 1 week later or 3 week later... Could you examine the prevboot logs please? ** Attachment added: "prevboot4.txt" https://bugs.launchpad.net/ubuntu/+bug/1823583/+attachment/5265059/+files/prevboot4.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823583 Title: Xorg freeze ( also Nvidia freeze (tested) ) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1823583/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
