NVIDIA Quadro G-Sync II User Guide

The following are the basic steps:

1.Open a display connection to each X Screen you want to control in your frame lock cluster.

Make sure you have privileges to establish the X connection.

2. Query the NV_CTRL_FRAMELOCK attribute to determine if frame lock is supported on each X screen.

3.Set NV_CTRL_FRAMELOCK_MASTER to NV_CTRL_FRAMELOCK_ MASTER_TRUE on one node in the cluster; set it to NV_CTRL_ FRAMELOCK_MASTER_FALSE on every other node in the cluster.

¾ Set NV_CTRL_FRAMELOCK_POLARITY for each slave node in the cluster.

Most likely, you want NV_CTRL_FRAMELOCK_POLARITY_RISING_ EDGE.

¾Set NV_CTRL_FRAMELOCK_SYNC_DELAY as appropriate for each

node.

Most likely, you want 0.

¾Set NV_CTRL_FRAMELOCK_SYNC_INTERVAL as appropriate if you

are using a house sync. Most likely, you want 0.

¾Set NV_CTRL_FRAMELOCK_SYNC to NV_CTRL_FRAMELOCK_SYNC_ ENABLE on each X screen to enable frame lock.

¾(Optional) Set NV_CTRL_FRAMELOCK_TEST_SIGNAL to NV_CTRL_

FRAMELOCK_TEST_SIGNAL_ENABLE followed immediately by

NV_CTRL_FRAMELOCK_TEST_SIGNAL_DISABLE.

This guarantees accuracy of the Universal Frame Count (as returned by glXQueryFrameCountNV()).

¾When you are done, set NV_CTRL_FRAMELOCK_SYNC to NV_CTRL_

FRAMELOCK_SYNC_DISABLE on each X screen to disable frame lock.
