Friday, Feb. 26, 2021 Followup. Yesterday, 2/25/2021, my machine was free of errors. I had no illusions that my screen problem had miraculously gone away, and I was right. This morning, 2/26/2021, I found the following errors:
1: My scheduled nightly backup (to an external USB disk) had not happened. 2: The screen-scrambling problem returned. 3: The machine did not blank its screen after 15 minutes, as it is configured to do. 4: Although my temperature monitor did not report anything unusual, the machine was running noticeably warmer than usual. 5: The Bluetooth drivers were not loading, leaving my Bluetooth mouse unusable. 6: The screen breaks up and becomes unusable at approximately 20-second intervals. (I am typing this during the moments of usability). I had to reboot and/or pause the machine in order to suppress the video problem to the extent that I am able to file this comment. Several times it went into Pause mode spontaneously. The periods of screen unusability are becoming longer. Please advise me when any further developments appear. --John -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916778 Title: After 5.4.0-66 kernel upgrade, HP Spectre screen flickers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1916778/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
