Displaylink CPU Usage high in Ubuntu 18.04
Hello,
I am using a reasonably fast Dell laptop with a Dell 3100 docking station under Ubuntu 18.04 and the CPU usage seems extraordinarily high (> 100% when playing a youtube video on an external screen... More than one processor is needed for that?). Also, Xorg seems to have more CPU usage than I would expect. |

Same issue on my laptop
As I posted in the other thread the fix does not work for me as it is obviously not log writing that is the issue for me.
I'm on a DELL Latitude E7250 laptop with SSD and i7 processor using Xubuntu 18.04 with Xfce using latest 4.2.29 driver. If I have nothing going on on either display CPU usage is not exceptional (<10%). If I start doing anything like grabbing a window and "wiggle" it the cpu quickly rises to >100% If I check the threads in top there are threads called DeviceWindowDis and SourceEngine_00 that sky rockets when I wiggle the window. |

I experience the same problem on Ubuntu 18.04 with DisplayLink Driver 4.4.24.
Is there any fix? |

Same same
I'm having exactly the same Problem and created an account just to put my voice behind the cause.
So i'm using a lenovo miix-520 with an ubuntu 18.04 and displaylink is routinely using 100-200% CPU load on multple processes. This is way overboard. I'm not even doing anything remotely graphically heavy. As soon as the load increases the performance goes into the cellar... A quick google search tells me that this problem seems to be around for over a year now. Will this problem ever be addressed or should linux users just ditch DisplayLink? |

Looking at how many threads are here with a high CPU load on Ubuntu and how little anyone from DisplayLink cares about it, it looks like they are giving a **** about Linux support. It's a real pity ... DisplayLink could be such a great solution, but ...
Unfortunately I didn't look in this forum before I bought this stuff ... I do really regret having bought a dock which is using DisplayLink ... |

I have the same problem but using Antergos (Arch Linux). CPU usage is continually high, even when I'm doing basically nothing on the computer.
