I found something interesting that may or may not be valuable. From what I can gather so far, we're dealing with two flicker issues. One affects only Ubuntu MATE, the other affects regular Ubuntu as well. For me, I've been able to work around the problem in Ubuntu MATE by disabling tlp.service and rebooting. After I do this, I no longer deal with any flickering at all whatsoever. This work around won't work for everyone, but if you are hitting the bug in Ubuntu MATE (since Ubuntu MATE features tlp.service by default) this may work for you.
Even though disabling tlp.service fixes it for me, this is still a kernel bug, because I can also fix this issue by side-loading an unsupported kernel without disabling tlp.service and that fixes it too. For whatever reason, tlp.service is triggering something in the kernel causing a flicker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1522922 Title: Screen flickering in Intel i915 driver To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/1522922/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
