DisplayLink and Wayland

Hi all,
I apologize in advance if I posted into the wrong section.

I have a gnome installation, running on Wayland.
I need to be able to use DELL DA100 adapter (from usb to ethernet, VGA, etc) and I started to follow this guide https://wiki.archlinux.org/index.php/Di … xx_Devices

Anyway the command
xrandr --listproviders
returns no devices.

Any idea?

Thank you very much.
Best

Re: DisplayLink and Wayland

DELL DA100 seems to be an USB3.0 device, did you install the "displaylink" driver? (Your link points to the usb2.0 section with udl)
According to the talk page it works since kernel 4.1, you might also have to plug in a screen first.

Hi progandy,
thanks for helping.

Right now I installed the "displaylink" driver, but nothing changes.
xrandr --listproviders
returns always no devices (even if the monitor is plugged).

The only "improvement" is that the system reacted when I connected the monitor (it tried to switch the screen but without success).

Thank you!

xrandr will not work under Wayland. You have to use your compositor's monitor configuration tool.

e.g. on Gnome:
`gnome-control-center display`

Re: DisplayLink and Wayland

I just looked at it again, and displaylink seems like an ubuntu/google sponsored project for the linux part, so wayland support is most likely not implemented. Support is only there for the android and ubuntu graphics stack.

Thanks progandy...so at the end it will be very hard to get it working...

I'll give a try to a common HDMI -> VGA adaptor.

Thanks!

Re: DisplayLink and Wayland

It seems that someone managed to have it working with Fedora?
