DisplayLink's USB Display Docks Should Work Nicely On Wayland With GNOME 3.32.1+
A Phoronix reader pointed out that as of GNOME 3.32.1, those with DisplayLink hardware should be in good shape for Wayland support. That's after GNOME 3.32 made many underlying improvements around multiple GPU support, GPU hot-plugging, and other infrastructure improvements to benefit the likes of DisplayLink USB-driven displays.
But for the GNOME 3.32 point release there is this fix to avoid a crash on EGL initialization with multi GPU setups. That fix is in GNOME 3.32.1 to ensure a working state for DisplayLink on GNOME under Wayland. That fix was also SRU'ed for Ubuntu 19.04 so the DisplayLink support is in good shape there.
The now-good GNOME Wayland state was confirmed by DisplayLink in their forums.
