Solved linuxulator switching to non root user in the chroot to run davinci resolve

i already have the shim set up on freebsd and working with obs studio nvenc encoding
ill go through all the steps and document stuff as i go

the linux browser install script

github.com

GitHub - mrclksr/linux-browser-installer: Script to install Linux browsers under a Linux chroot on FreeBSD

Script to install Linux browsers under a Linux chroot on FreeBSD - mrclksr/linux-browser-installer
github.com github.com

has wrapper scripts that start pulseaudio on the host and gets it working with the chroot
and then launches the browser in the chroot

idea is to repurpose those scripts to launch resolve
 
thats a piece of the puzzle for later
i always plan ahead and try to have idea of the things might come up and how to solve them
 
hi mate, making progress

chmod the nvidia run script

Code: 
chmod +x NVIDIA-Linux-x86_64-535.146.02.run

install the nvidia driver

Code: 
sudo ./NVIDIA-Linux-x86_64-535.146.02.run --install-compat32-libs --no-nvidia-modprobe --no-backup --no-kernel-module --no-x-check --no-nouveau-check --no-cc-version-check --no-kernel-module-source --no-check-for-alternate-installs --install-libglvnd --skip-depmod --no-systemd

run nvidia-smi in the chroot
and it works

installing packages for resolve

Code: 
sudo apt install nvidia-cuda-toolkit ocl-icd-opencl-dev libglu1-mesa libfuse2 initramfs-tools

45 minutes to download

next step use debootstrap to create a deb installer for resolve

at this stage in the how to guide

will take about an hour

davinci resolve installed didnt take as long as i thought to build the deb

next step create a launcher for resolve
my idea is to use the linux browser script launcher and modify it to launch resolve
 
as you can see,my suggestions are very careful...I hope that when you will be able to run it,you want to help me to fix this error that prevents me from running resolve :

Code: 
sh << EOF
env LD_LIBMAP="`nv-sglrun printenv LD_LIBMAP | grep -v libGL`" /compat/ubuntu2310/opt/resolve/bin/./resolve
EOF

=

/compat/ubuntu2310/opt/resolve/bin/./resolve: error while loading shared libraries: libgpudetect.so:
 cannot open shared object file: No such file or directory

and that I'm not able to fix it....

PS : I have just fixed the error above using this trick :

Code: 
ln -s /lib64/libcrypt.so.2.0.0 libgpudetect.so
 
I'm very happy. After a lot of tries and perseverance,I've been able to run Davinci Resolve and most important,it recognizes my GPU and even the CUDA libraries :

How to reach this result ? running inside the linuxulator this script :

Code: 
bash << EOF
xhost +
LD_PRELOAD=/home/marietto/Files/dummy-uvm.so /opt/resolve/bin/./resolve
EOF
 
yes,X11. I'm not sure that wayland is mature enough to use it everyday...maybe in some years...so. Does Davinci Resolve work with X11 for you ?
 
wayland is great on freebsd with dwl, no issues at all

ive been using wayland for a couple of years without any issues at all
on ubuntu, fedora, nixos and freebsd

ive always run resolve on wayland
not going back to x
