This happens to me every week on Ubuntu 16.04. LTS with kernel 4.15.0-112-generic. It seems to be a random complete system freeze. The mouse does not respond, caps lock and numlock do not change light on keyboard, ctrl alt f2/f3/etc does not work, and even Alt + SysRq REISUB does not respond. Only a hard reset works by pressing the power button will reboot the system.
I noticed I could reproduce the bug easily by watching videos and/or reading news on "heavy" newspaper websites in Firefox. In contrast, in Chrome I rarely experience the issue. >From what I have read, and since I have a GeForce GTX graphic card with original NVIDIA drivers installed, I suspect that the problem is strongly related to these three components: video encoder/decoder, browser and graphic card/drivers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798961 Title: Random unrecoverable freezes on Ubuntu 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1798961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
