It's seems like a problem with upstream driver, especially since even I remember reporting one last year.
Hence I would suggest your report an issue there.
Thanks for the reply I posted the issue there. so as for the fix there is none? What i have been doing is rebooting wait till the OS boots up and then connect sometimes the CPU does not go UP and sometimes it does very odd
Same problem here...
As part of https://github.com/AdnanHodzic/displaylink-debian/commit/b57cea89cc2e97de071e417bdd39ddd374072dbd commit udl/udlf will be added to blacklist.conf automatically if >= 4.14.9 is detected.
Since I never got output of sudo ./displaylink-debian.sh --debug
I'm not sure if this will fix your problem, but I'd definetely advise you to pull the latest changes and perform reinstall.
I've just merged displaylink-5
branch with master
which introduces big changes, among which are support for yesterday released DisplayLink 5.1 driver. Disabling modesetting as part of displaylink-debian
as now all of it should be happening on EVDI level. I've included few more changes.
Regardless, please pull latest (git pull
) changes on master
and run sudo ./displaylink-debian.sh --install
After this everything should be working as expected and with this said I'm closing the issue. If the issue still persists, re-open the issue and include output of sudo ./displaylink-debian.sh --debug
command.
I'm having a similar issue on Kubuntu 18.04
Just having some windows open and running top, I typically see DisplayLinkManager using between 20 and 25% of a cpu. If I start making circles with my mouse, it jumps to over 70%. If there's a video playing, it jumps to over 100% (obviously meaning it's using more than 1). The more I do, the more CPU it demands. This is after a fresh install and reboot. Simple things such as opening a new browser tab spikes the cpu usage of DisplayLinkManager. It seems anything I do is causing the CPU to go wild. I will be creating a ticket with evdi as well, but since I found this first I thought I would share. Also, every once in a while, it will just fail. The monitors will just go blank and I have unplug the usb and reconnect it. Sometimes that works just fine and other times it messes up my desktop config.
This is the result of running the script with the debug flag:
