I am unable to get Cinnamon or Gnome desktops to use my thunderbolt display.
A little background:
Razer Blade 17 laptop
Razer Core 2 enclosure
Fedora 29 with 5.0 kernel
Nvidia 4.19 drivers installed.
nvidia-smi shows both the internal GPU and the 2080 graphics card.
xrandr --listproviders only shows the built in video gpu
nvidia-settings only shows the built in gpu
In xorg.conf I see both the internal and external gpus listed (Device0 and Device1) I also see Monitor0 and 1 and Screen0 and 1.
If I boot up Win10 on it, everything just works.
Really has me stumped. Any idea what I might have wrong?
