[Bug 1663989] Re: Screen flickering
Confirmed that the bug is fixed in the 4.10 kernel series. Further confirmed that this is down to the i915.enable_psr parameter: Linux 4.8 with no command line => flickering (enable_psr defaults to on) Linux 4.8 with i915.enable_psr=0 => no flickering Linux 4.10 with no command line => no flickering (enable_psr defaults to off) Linux 4.10 with i915.enable_psr=1 => flickering ** Package changed: nvidia-graphics-drivers (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663989 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry I should have explained better, I also have a Lenovo Edge E540 which is how I initially found this bug report via Google, but mine does not have the nvidia chipset, only Intel, so I didn't see how this could be caused by the nvidia driver. I will try to test the newer upstream kernel when I get time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663989 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1663989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Now that I had another look i-mail-3 has a hybrid system, so test the mainline kernel first and if it does fix the flickering then move back to linux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663989 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1663989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Dave, don't hijack bugs, this was originally filed on a system with nvidia, your bug is not the same. ** Package changed: linux (Ubuntu) => nvidia-graphics-drivers (Ubuntu) ** Changed in: nvidia-graphics-drivers (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663989 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1663989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1663989] Re: Screen flickering
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Bug 1663989] Re: Screen flickering
Same issue, although I only have Intel graphics. Adding i915.enable_psr=0 to the kernel parameter line fixed the flickering for me.
