Mountain Lion Problems

chandler767,

I had the same thought, and was curious all day what type of workaround could get this to work. Glad to report that for the first time in a few months I have my DisplayLink device working great...

This whole problem is bizarre, because the drivers seemed to work for a month after I got it, but then started having the Finder crash issue, Login screen missing, and Flash crashing in the browser problem.

So here is what I did (this just happend, I may recreate everything later to give more details).

Install driver, reboot. Do not plug in displayport device yet (I did, but I guessed where the login button was, not sure if the results will be the same if device is not plugged in)

After login, plug in device and monitor.

Open terminal, and type:

Code:

sudo kextload /System/Library/Extensions/DisplayLinkDriver.kext

Logout, Login and you should be good to go.

If this doesnt work, try (your system will probably crash/Kernel Panic):

Code:

sudo kextunload /System/Library/Extensions/DisplayLinkDriver.kext

Then startup again, login and run the kextload command above, logout and login.

If you need to reboot, try unplugging the USB adapter, then rebooting or shutting down. After login plug it in.

This entire set of instructions may be as simple as: Do not boot with the device plugged in, if you can you are missing the login buttons, and can guess, just plug in device, reload kext and logout/login.

I take no responsibility for the accuracy of the above..it may just be my luck..this is a '12 13" MBP, 10.8.2.

Let me know how this works for everyone..very hacky and a PITA, but maybe DL can get a workaround going in the meantime.
