I figured even before reading http://plugable.com/2014/03/06/displaylink-usb-2-0-graphics-adapters-on-linux-2014-edition that DisplayLink won't work with proprietary nVidia driver. I also see that the USB monitor (and AOC) is activated while the machine is booting. As soon as the proprietary driver kicks in, it blanks out.
If I enable nouveau driver and reboot the machine, only the USB monitor shows the graphical display, and my notebook's monitor remains blank. When I look into Unity's standard "Displays" settings, only the AOC monitor is detected. (When I run proprietary nVidia driver, only the Built-in Display is detected). The color depth is very low though, but I wouldn't mind that too much as a secondary monitor. I know it's not for gaming or video.
Could anyone help with this? I'm running latest stock kernel of 64bit ubuntu: uname -a: Linux erebus 3.13.0-46-generic #79-Ubuntu SMP Tue Mar 10 20:06:50 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
I can provide any other logs if needed, but I don't want to unnecessary clutter this post in advance. I hope someone else already got it working with this combination: Ubuntu 14.04 64 bit, nVidia GPU and DisplayLink monitor.
I got this to work on my Laptop with Intel Graphics + Nvidia 870M by switching the GPU from Nvidia to Intel using Nvidia X Server Settings. I'm using the Nvidia proprietary driver 352.xx and the latest displaylink linux drivers from displaylink's website.
Check what kind of DisplayLink monitor you have. In my case an AOC e2251fw, and it turned out that it uses DL-165 chipset, and for DL-1xx chips you won't need the EVGI driver + new DisplayLink driver. You can use the
udl
kernel driver and it even works along with the proprietary nvidia drivers.See more: https://wiki.archlinux.org/index.php/DisplayLink and http://www.displaylink.org/forum/showthread.php?p=81545#post81545
Still have some issues though: Giant virtual monitor with DispayLink monitor + Xfce with additional annoying scroll effect
My display-link on Ubuntu 16.04 only worked with nouveau and Unity (not xfce, gnome etc). With nvidia driver I couldn't even see the external displays/
