Ubuntu 17.10 with DisplayLink 1.4 - Laggy mouse, CPU usage dependent

galeon · 12-01-2017, 08:19 AM

Hi guys,

I fought with some similiar problems. Laggy screen, high CPU usage and I just tried this from another thread:

Code:

echo 1 > /sys/devices/evdi/add

My system instantly became more responsiveat a level I totally forgot it existed (except when the CPU is under high usage, but that is still better than it being always in stat state)
To be frank: That is far from what I actually would expect and I'm still mad as hell about it and would not buy any system where I would have to use a DisplayLink device again.

Ubuntu 17.10
Dell XPS 13
External Monitor connected via D3100

I still have to figure out what this actually does and make it permanent.

Hope it may help someone.

Cheers,
Finn
