Public bug reported: Upon upgrading to 17.04 (also confirmed in 17.10), heavy, almost constant screen tearing presents itself immediately at the graphical or text splash page (i.e., before the operating system loads). The tearing continues after reaching the lock screen and logging in. The tearing is nearly constant, stopping only for certain actions like using the mouse or typing.
The screen tearing can be "fixed" by issuing i915.enable_rc6=0 in the boot parameter. However, this is a false fix as it turns off important power management functions and, as a consequence, the fan runs constantly and on high. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: intel -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708480 Title: Ubuntu 17.04/17.10 Screen Tearing on Intel KabyLake Graphics Cards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1708480/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
