I would like to describe conflicts using Nvidia Prime, Displaylink and Ubuntu in my experience.

My environment: Ubuntu 18.10, Nvidia GTX 1070 (nvidia-driver-415), Displaylink 5.1, Asus MB168B+ (USB monitor), laptop Gigabyte Aero15x.

If I try to login with nvidia profile activated and anything connected in USB ports (even only a mouse), I will face a login loop. It only will stop after disconnecting all USB devices, restarting the system and then I'll be able to login into my Ubuntu. Once logged in, I can connect my USB devices and use everything included my second monitor.

If I try to login with intel profile activated. There will be no problems. Displaylink works ok.

Another interesting behavior. If I start up my laptop with all USB devices connected, of course only possible using intel profile; Displaylink will work perfectly. But if instead, during an current session I plug on my external monitor, I will always see blurry and weird definition around the mouse pointer.

If Displaylink could improve this will help lots of Linux users.
Thanks!

Hi,

I had to downgrade to Sierra 10.12.6 because of the multi-monitor incompatibility of Displaylink 10.13.4. I need my multi monitor setup. But the truth is that Displaylink 4.1, which is compatible with Sierra 10.12.6, deactivate iTunes movies. Here is the message:

The selected display won't play on one of your connected displays

This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection). Try moving the iTunes window to a different display. Make sure the entire window is on the supported display.

When I remove Displaylink from OSX 10.1206, iTunes movie start to plays back. In short, Displaylink make the my iMac see it's own screen as an external monitor which is totally ridiculous from an programmer standpoint. This is not mention into know problems between Displaylink and Sierra 10.12.6. I manage to sent an email to the company without any respond. They probably did not liked the way I express myself, but I was piss.

Anyhow, anybody who can't see a movie and need multi monitor : downgrade to Sierra 10.12.6 and install Displaylink 4.1. Uninstalled it when you really want to watch a movie. Reinstalled 4,1 when you really need your multi monitor. Since I cannot upgrade in between 10.12.6 and 10.13.4 there is no way if an update between those versions would had fix this ridiculous problem. At least now, I can do My job and enjoy a movie on Saturday night by going through this annoying procedure.

Thanks

I have a 12inch 2880x1920 monitor (eDP-1) and a 21inch (eDP-1) with a 1920x1080 native res. I tried to use

xrandr --fb 6720x2160 --output DVI-I-2-2 --mode 1920x1080 --right-of eDP-1 --scale 2x2 --panning 3840x2160+2880+0

and I got:

X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 29 (RRSetPanning)
Serial number of failed request: 46
Current serial number in output stream: 46

I have an Asus t303ua
with:
VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) (prog-if 00 [VGA controller])

Is there a plan to support panning in the future on Linux?

I am a video deejay using a Macbook that has a failed GPU so i currently rely on one of your devices to connect to an external display.I upgraded to Mac OS High sierra and realized that my display link driver works differently(blue airplay icon) and i have much better performance now(faster frame rates with mix-emergency & Serato ,transparency on the dock And task bar),thank you for that .But The problem is Mac Os High Sierra is Just too Unstable right now for example due to the failed GPU i have completely disabled it but because of that my laptop does not sleep when l close the lid also when it sleeps it cannot wake the screen when i wake it up also i cannot control the screen brightness worst of all i have experienced 3 complete unrecoverable Os crushes in the past two weeks since finally upgrading to high sierra from mac OS sierra so i`ve reinstalled mac OS sierra and my computer works just fine now but im back to the older functioning display link driver that has better resolution on my external display running natively in 1360*768 resolution but has much much lower frame rates on both mix emergency and virtual DJ video output because it doesn't work like the air play one on high sierra .

so my suggestion is that you please implement the same airplay idea on high sierra it works much better

my current display link hardware is a USB 2.0 to dvi ,hdmi and vga (USB 2.0 UGA 17)

If the DisplayLink driver existed in the kernel, it would be SO much easier for the users to get it working. In my role as Chief Digital Officer for a large company (of 8000 people), I would probably have bought 500 of these devices IF the driver were just upstream (you know, how Linux devices normally "just work" without the aggro common in the Windows world). However, the annoyance of a manual driver install, especially when it's broken on updates to newer kernels, is just something I wouldn't want to invest in. Please consider that proprietary drivers are serious impediment to sales, and just work with a willing community upstream.
