![]() This is because the Oculus DK2 Camera has some issues on USB 3.0/Hybrid 2.0/3.0 ports. Xhci_hcd 0000:04:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? If you are receiving an enormous amount of messages in the kernel log that look like this: Troubleshooting Kernel log spamming by DK2 camera Xrandr -output DVI-I-2 -primary -auto -rotate normal -panning 1920x1080 -scale 1x1 -output DVI-I-3 -off The above video modes can have some havoc on your display if you simply use xrandr -auto, as it will still try to scale something. If you prefer panning, change -scale-from to -panning. ![]() This command will set the primary monitor to have a scaled version of the entire display. Xrandr -output DVI-I-3 -primary -rotate left -mode 1080x1920 -rate 75 -auto -output DVI-I-2 -mode 1152x864 -rate 75 -auto -same-as DVI-I-3 -scale-from 1920x1080Īlthough the Rift SDK reccomends not rotating the secondary display, not doing so seems to cause issues with a number of programs. Say our primary monitor is DVI-I-2, and DVI-I-3 is the Rift, and that 1152x864 is the highest mode that supports 75Hz. You should test each to see if each application works correctly unrotated first. Unfortunately only certain applications work correctly with this. With the display unrotated, this extra frame of latency is removed and you get a much improved experience (equivalent of Direct Mode on Windows). Note: Having the display rotated adds an extra frame of latency, which makes it operate at the equivalent of Extended Mode on Windows. The Rift itself needs to be the primary monitor, or synchronization will not work properly. In addition, if you have a cloned video mode in which your ordinary monitor runs at a lower refresh rate, then often games will lock themselves to the lower refresh rate. You also need to be in the input and video groups to have full permission, plugdev is no longer neccesary (as the mode is set to 0666).įor the Rift to function optimally, only certain video modes work very well. ![]() The oculus-udev AUR package will setup proper udev rules. The Oculus Rift device connects via HDMI as a secondary display to your graphics card, as well as by USB in order to perform as a sensor. If you want to use your Oculus Rift CV1 on Linux, you need to use OpenHMD instead. This article covers setup for the official Oculus Rift SDK on Linux, which supports DK1 and DK2 only (but not CV1). The Oculus Rift is a virtual reality head-mounted display developed by Oculus.
