It depends what you wanted to do, but you could have the X server feed the KLD commands to do on a vert refresh, and when it happens the commands are executed in kernel mode, which would save you a lot of time. Kind of complex though. Also the interrupt latency problem is still there. --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
