[Kernel-packages] [Bug 1666776] Re: UI performance slow (0, 5fps) when I disable primary notebook display

Thank you for the tip! Actually the CPU/GPU is pretty new, so the support definitely improved since kernel 4.4 (I think that the support for this GPU has been added in 4.3; kernel 4.4 had artifacts of hiding mouse cursor, 4.8 works pretty decently, apart from the abovementioned reported issue).

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? 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
