DisplayLink Forum - View Single Post - Yosemite Beta Driver Not Working

RBHCSD · 12-03-2014, 03:30 PM

I have a single DisplayLink USB3 Adaptor (MDS3900) attached to my MacBook Pro (15-inch display, Late 2011) version. While running Maverick (10.9) everything worked fine. I upgraded to Yosemite and it quite working.

I installed the new (Oct 2014) Beta driver for OS X and it started working again.

Setup Configuration -
I have a Dell P2414H 24" Display hooked to my Thunderbolt and another Dell P2414H 24" Display hooked to my DisplayLink adaptor. Both are running in 1920 x 1080 resolution mode and the Graphics Chip in my laptop is the AMD Radeon HD 6770M with 1024 MB.

Currently running 10.10.1 version of Yosemite (OSX).

I leave my laptop closed (clam shell) and only use the (2) 24" Displays while in the office.

Last week I put my system to sleep, unconnected everything and took my laptop to do a briefing. I opened up the laptop, logged in, and then connect the LCD Projector to my Thunderbolt/Lightening port using an VGA Adaptor. Everything worked perfectly. NOTE - the DisplayLink stayed in my office as I only use it there to get the two 24" displays working.

When the briefing was over, I disconnected the VGA adaptor, put my system back to sleep by closing the lid and then went back to my office. I plugged everything back in again and hit the return key on my keyboard to wake the system back up. Now the only display that works is the one connected to my Thunderbolt. The display hooked to my DisplayLink never wakes up and Display Preferences only shows the one display attached to the laptop.

I've installed the DisplayLink driver, rebooted my laptop, reinstalled the beta driver, rebooted the system, and still the DisplayLink does not work. I've opened up my laptop and the internal LCD screen comes on and Display Preferences now shows I have 2 displays, but the DisplayLink monitor is still dead.

I swapped the displays around and which ever monitor is attached to the DisplayLink does not work. I am using the dongle on the DisplayLink to go from DVI to VGA as that is the port I'm using on the monitors.

Looking at the console log file, here are the messages I get every time I plug in the DisplayLink.

Does anyone have any ideas on how to get this working once again??

Thanks!
