  1. Ubuntu drivers eating a lot of CPU. Not always but at least 50% of the times

    I have a 4 core, 8 thread i7 CPU for my laptop, and even when nothing is moving on display, it burns ~15% cpu per thread in htop on ubuntu 18.04 with DisplayLinkManager. If i try basic window navigation (just moving browser windows around), it goes up to around 30-50%. about three quarters of the CPU used appears to be in userspace. Note this is on a Dell D6000 dock driving 3 1080p displays through USB 3.1 Gen 1 and on a Dell Inspiron 13 7373.
