Bug Description
[Impact]
5.0 fixes screen flicker issues with new panel models and on hybrid machines, and Intel has prepared a backport for 4.15 which we can use. It consists of 50+ cherry-picked commits plus a handful of build fixes:
git://github.
[Test case]
Various display configurations with an external monitor connected need to be tested, preferably on a wider set of hardware
[Regression potential]
The backport was done by Intel, and tested with intel-gpu-tools to do the right thing, but there's always a chance of regressing something.
