Please find the libs here. I added the usual output for ldd, dmesg, lspci -vvv.
https://ferdi.naasa.net/oc/index.php/s/RC2edn5EW3kzR0D I don't know what kind of support tool you mean. If I search in google, I can find one for Windows. I've no windows, though. |

The support tool zip:
https://ferdi.naasa.net/oc/index.php/s/d5YU6YecUxX5Q0B Not sure if that makes sense - note that the D3100 is not attached at the moment (I'm not @home) and the DL service is disabled. If you need it to be attached, we'll have to wait until tomorrow. |

The logs of what was happening may be enough. Thanks.

Can you change the displaylink manager to log in clear text - or even better: provide the source for it. That I can look for the reason myself.

Hi cpo,
Could you please provide a bit more information about the context when the problem occurs? Is it constantly eating your CPU or you observe it only in some circumstances, e.g. CPU load is significantly higher when resuming from machine suspend? Is there any specific app running? Maybe capturing a quick video on your phone would help? I am asking as we would like to reproduce the problem internally. Thanks, Szymon |

Hi
I have a brand new XPS 13 DE, just installed ubutu 16.04, kernel 4.4.0-24 so I can make some tests. Indeed there is a problem with CPU. Here is my first test: * install latest Displaylink driver 1.1.68 * test if it work with my dock D3100 + external HDMI monitor: YES! * unplug the dock * reboot (laptop alone, nothing is connected) * in the terminal, "top" tells me DisplayLinkManager uses between 0% - 0.3% so this is fine * close the lid to suspend, re-open to wake up * now DisplayLinkManager is steadily using 16%CPU ! (with nothing connected) So something is wrong here. |

Here is the screenshot
(after resume, with nothing connected to the laptop) [EDIT] sorry, the image has been shrunk, it's too small.; Anyway this is not important It's just showing DisplayLinkManager at 16.9% CPU Last edited by sanette; 06-16-2016 at 09:11 AM. |

I'm having the same problem. As soon as I plug in a single DisplayLink screen, the DisplayLinkManager CPU usage goes through the roof.
The CPU usage stays this high (around 80-100% of one logical core) as long as I keep using the screen(s). See screenshot.
