This documentation assumes you have an nvidia graphics card. We have tested
on Ubuntu 14.04, Debian Stable 7.6, and Fedora 20.
WHAT SETUP IS REQUIRED?
* Appropriate permissions for Oculus hidraw devices. See
LibOVR/90-oculus.rules and ConfigurePermissionsAndPackages.sh .
* Use a non-rotated twinview setup or place the rift on a separate
non-rotated X screen.
* Ensure oculusd is running when using the rift.
BUILD INSTRUCTIONS
After installing the appropriate packages simply issue 'make' in the root of
the SDK directory. This will build a release version of Oculus World Demo
(OWD). To generate debug symbols use 'make DEBUG=1'.
HOW DO I RUN OCULUS WORLD DEMO (OWD)?
Either run the binary directly from the output directory, or use 'make run'.
SHOULD I ROTATE MY DEVICE'S SCREEN?
Manual screen rotation is not recommend. If your window is fullscreen on a
rift device, set the ovrDistortionCap_LinuxDevFullscreen distortion cap to
have the SDK automatically rotate the distortion mesh on appropriate devices.
Be aware you will have to account for window size. You can use
OVR::SDKWindow::findDevScreenForHMD (Displays/OVR_Linux_SDKWindow.h) to
return the screen offset and dimensions necessary to size your Linux window.
See Samples/CommonSrc/Platform/Linux_Platform.cpp for an example.
SEPARATE X SCREEN
ConfigUtil will not currently work across X screens. You will need
to use TwinView to use ConfigUtil.
TWINVIEW
You must sync to the Rift's display device for a smooth experience when using
twinview. To consistently sync to the rift with Twinview setups, set the
__GL_SYNC_DISPLAY_DEVICE environment variable to the appropriate display
device before X starts. For example in your /etc/profile you could place the
following:
export __GL_SYNC_DISPLAY_DEVICE="DFP-1"
if you're rift corresponds to DFP-1.
STARTING THE TRACKING SERVICE AUTOMATICALLY
Start the tracking service when a user is logged in using Xsession files.
UBUNTU USERS
There was a kernel bug which affected HID devices in 14.04. If you find you
are receiving feature report failures, please upgrade your distro as the
bug is now fixed.
