Failing to wake up from sleep? Try disabling your screen saver.
As the title suggests, mine was crashing out, but I noticed the screensaver glitch slightly before it froze.
I set my screensaver time to "never" and have since had no problem coming out of sleep mode. I hope this helps people and isn't just a coincidence! Cheers, |

Thanks
I'll try it. Hasn't been a major issue, but I'd be lying if I said it never affected me. Thanks.

Sometimes you can just wait
I've had this lockup issue several times now when waking from a long sleep (longer than 5 minutes). Other than that, everything is fine. I've waited several minutes (10-15) many times and my MBP will recover, so it's unclear what is going on (I haven't checked console messages yet). It appears to lockup the computer, but many times its just the screens. My sound and keyboard still work.
It's almost like letting it go back to sleep allows it to wake up properly, for lack of a more technical description. |

Waking from sleep
There is an option in the Screen Saver preferences -- "Main screen only" -- I'm going to try that and see if that solves it also.

No, the "main screen only" checkbox doesn't solve it.
Also, disabling the screen saver entirely doesn't solve it either. It seems that when the display goes to sleep, that's when it crashes. |

Interesting. Yesterday I had just set my display sleep to be the same as the computer sleep (since apple won't let you "disable" the display sleep) to see if that had impact. I haven't noticed the "lockup" yet...

Tried that... does not help. I think the only solution is to disable sleep entirely.

Possible solution
Possible solution -- seemed to have worked today.
Use sleepwatcher. Add the -S and -W options to /Library/LaunchDaemons/de.bernhard-baehr.sleepwatcher.plist to run display sleep and wakeup scripts. The display sleep script should be: launchctl remove com.displaylink.usbnivolistener The display wakeup script should be: launchctl load /Library/LaunchDaemons/com.displaylink.usbnivolistener.plist This will cause the driver to be disabled during display sleep and re-enabled during display wakeup. It is very fast, unlike the uninstall/reinstall driver trick. The driver stays installed, just disabled. |

Looking good
The solution I posted above has now worked for 2 days. Previously it was crashing 3 times a day -- so I'm starting to feel good about this. Try it out and let me know what you think!

Which version of the driver are you using? What OS X version and hardware revision? My driver version was installed as a launch agent, not as a daemon. Therefore, the command to remove you gave does not work for me (I already use sleepwatcher). I've managed to directly remove the driver, which resulted in an a kernel panic.
