When I first installed DaVinci Resolve on my Dell XPS under Ubuntu 19.04 I was greeted with stuck splash screen. What was I missing?
Well, the first issue was missing OpenCL. Fortunately that was easy to solve:
sudo apt install ocl-icd-opencl-dev
Other issue was missing nVidia driver. For some reason Resolve really dislikes nouveau driver. Therefore we have to upgrade driver a bit. I found that auto-install works perfectly for me:
sudo ubuntu-drivers autoinstall
Those who like to be more precise can always check which drivers are available and install only those:
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001C8Dsv00001028sd000007BEbc03sc02i00
vendor : NVIDIA Corporation
model : GP107M [GeForce GTX 1050 Mobile]
driver : nvidia-driver-390 - distro non-free
driver : nvidia-driver-418 - distro non-free recommended
driver : xserver-xorg-video-nouveau - distro free builtin
sudo apt install nvidia-driver-418
With these two changes my DaVince Resolve can finally start properly.
PS: Interestingly, installing non-free nVidia driver solved Ubuntu getting stuck booting after incorrect password got entered.
