Dsiplaylink Driver and Ubuntu 18.04

mss · 05-17-2018, 10:38 AM

Hi,

I just got a new HP Envy 17inch (i7-8550U and 16GB) with 2 Samsung curved screens plus the i-tech CADUAL4KDOCK.

Same problem with the drivers. Managed to make the screens work and also have the flickering mouse pointer and the square around it.

The problem is that the computer moves really slow. Any suggestions/ideas why? Surely the CPU and memory are not an issue.

Would help if the driver has support for Nvidia cards. Mine is GeForce MX150/PCIe/SSE2.

@Displaylink Team, please make the drivers for Ubuntu 18 or get a solution for this.
You have a great product (hardware) and software should be up to date too.

Sounds more like a USB bandwidth ...

I have a totally different problem...

My early displaylink works fine ... but when i reboot, its not detected ... i must unplug and reinsert. Then xrandr the display into operation ...

It looks like this problem, and workaround is included (I haven't tested this personally):

Please note when I say "it looks like this problem" I'm talking about the original problem that started this thread ("looping back to the login screen"), not your issue which, by your own description, is "a totally different problem".

It's confusing to try to discuss different problems on a single thread; it would be better to create different threads for different problems... they don't cost anything!

Give this a try:

...note that I was unable to get this working with the nvidia proprietary drivers. I had to use the nouveau drivers

I'm still in Ubuntu 16.04, and have the same issue on mine Lenovo Ideapad 720S with Nvidia 1050 on board.

I found the workaround is to log-out and log-in again once OS is started.

BTW. tried 3 lates versions of driver and the issue persists.

I published this video with the issue: Display Link issue with cursor

Hi everybody, had this issue for some time on different Ubuntu based distros.
Nvidia + DisplayLink and one external display.

Mouse flickering was present on builtin display.

I've managed to solve the issue by restarting display manager service.

Code:

$ sudo service lightdm restart

Hope this helps.

Thank you madscientist. I had the same issue (I have ASUS MB169B+ as second monitor):
1. Mouse cursor artifacts on GTK menu bars.
2. After rebooting laptop with connected usb cable the monitor is not connected.
But now both problem are solved.
