Some known issues

unsupported tarball input

       error: unsupported tarball input attribute 'lastModified'

Solution:

jq '.nodes |= map_values(if .locked.type? == "tarball" then .locked |= del(.lastModified) else . end)' flake.lock > flake.lock.new

SteamVR not launching

First you have to run this command after installing SteamVR:

sudo setcap CAP_SYS_NICE+ep ~/.local/share/Steam/steamapps/common/SteamVR/bin/linux64/vrcompositor-launcher

Then add this as launch option in SteamVR settings:

QT_QPA_PLATFORM=xcb __GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD=1 VK_DRIVER_FILES=/run/opengl-driver/share/vulkan/icd.d/nvidia_icd.x86_64.json /home/pablo/.local/share/Steam/steamapps/common/SteamVR/bin/vrmonitor.sh %command%

And this for every VR game you want to launch through Steam:

QT_QPA_PLATFORM=xcb __GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD=1 VK_DRIVER_FILES=/run/opengl-driver/share/vulkan/icd.d/nvidia_icd.x86_64.json %command%

Note the additional QT_QPA_PLATFORM=xcb at the beginning, apart from what ALVR recommends.

Also note the VK_DRIVER_FILES path may vary depending on the nvidia version you have installed.
