If nothing gets added to the output when the flickering happens then that answers my question, thanks.
This still feels like a kernel bug if not a hardware problem. Do you notice any change if you wiggle the laptop screen? Try moving it forward and backward. We next need to check if it's related to a loose connection either in the screen or relating to the screen hinge. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1839253 Title: Excessive screen tearing and flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1839253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
