High CPU load (D3100 Ubuntu 15.04)

[R.E.L]

Hi together,

I have an Ubuntu 14.04 trusty up to-date. An Year ago my DisplayLink was working with a lot of changes in the udev. Then I don't need the second display using DisplayLink. Now I have a need to use the second display. It now does not work.

So I investigate and found the new DisplayLink driver for Ubuntu and installed them. First it doesn't work because I had kernel 3.13.0-45. I Installed LTS wily kernel 4.2.0-35. After some display settings it works with a many crashes an always an poor performance. The mouse moves very slow and tipping an character takes seconds.

I take a deep look at it and found a solution:

• sudo displaylink-installer uninstall

• Remove my old DisplayLink udev entries

• create a file /etc/modprobe.d/98_no_udl.conf with data: blacklist udl

• reboot

• run install

• sudo ./displaylink-driver-1.0.335.run

Now the DisplayLink display and my primary display working without any problem.

Hope this helps You to regards Rainer
