wayland is not supported, but xorg-wayland works
NOTE:
use steam, not steam-runtime (arch uses much newer libs)
You'll need vulkan drivers for your videocard.
sudo pacman -S vulkan \ lib32-gtk2 \ lib32-libva \ lib32-libvdpau \ polkit-gnome \ pavucontrolqt # nvidia sudo pacman -S nvidia-utils \ lib32-nvidia-utils \ vulkan-icd-loader \ lib32-vulkan-icd-loader # icd-loader installs AMD's vulkan driver # if using nvidia, specify it's driver VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json steam-runtimeFirst time setup
- pavucontrol-qt: - select TU106 HDMI for playback - terminal: - sudo /usr/lib/polkit-gnome/polkit-gnome-authentication-agent-1 - terminal: - steam - Locate and install steamVR in store # at some point you'll be prompted to enable steam permissions using polkit-gnomeRegular Run
pavucontrol-qt # select TU106 for playback steam
Preparation
Headset Configuration
- Remove the rear-insert, it is designed only if headset is not tight enough
- Measure IPD (mine 4.6mm) and adjust as much as possible
- Adjust focal as near as possible to your face
- Darken brightness (30% for me)
In Headset Tips
- Stay hydrated
- Use eye drops
- Remember to blink
- Generally, focus forwards and turn head rather than using peripheral vision
- Stop before eye-headaches/light sensitivity
- When stoped, look at something in the distance
Configuration
Performance
NOTE:
Under linux, in first few seconds of home, buttery smooth. Then gradually lag sets in.
General
- Within steamVR settings, decreasing framerate to 120Hz helps a lot
- Within steamVR's per-application video setttings, advanced, decreasing resolution helps
Linux
- Disable X11 compositors like
xcompmgr
to improve performance- 3x individual 1080p displays vs one large TwinView screen helps performance slightly
Game Resolutions
You may not be given a choice in-game to change the resolution,
but you can enable advanced video settings in SteamVR, and set one per-application.
