2.4.1 on YOSEMITE not working
 

hello
i'm using USB to VGA 165.
since i've uprgraded 10.9 to 10.10 the 2nd screen not displaying anymore (3/4 months ago now)
i've tried 2.1/2/3 macosx drivers and now the last 2.4 beta driver but i'm disapointed cause nothing change, screen still black.

ok i have attached to this post, all files the debug tool made
ok like this?

Thank you xav,

The logs show that only part of the DisplayLink driver is running on your system. The service itself cannot be started.

The first thing to do in this case is:
- Use the uninstaller in the DisplayLink disk image and uninstall the driver
- Open Disk Utility
- Select your startup drive and in the "First Aid" panel click on "Repair Disk Permissions"
- Once Disk Utility has repaired the permissions, install the 2.4b1 driver again

This usually fixes most installation issues, please let me know if you are still having issues.

Kind regards,
Carlo

thx for your reply
i did it twice but still not working

Hi xav,

At closer inspection we found out that you probably don't have a directory that we need to install on Yosemite.
It's a new one in 10.10 so probably got left out in the upgrade.

To create it, open Terminal and execute the following line:
sudo mkdir /Library/PrivilegedHelperTools

You'll need to enter your administrator password. Then repeat the previously mentioned steps: uninstall DisplayLink, repair permissions, install DisplayLink

Let us know how it goes!

Best regards,
Carlo

thanks for prompt answer
the terminal line made: mkdir: /Library/PrivilegedHelperTools: File exists
i did: uninstall DisplayLink, restart, repair permissions, install DisplayLink, restart
but nothing change

This is puzzling. The installer for some reason cannot create our subdirectory inside /Library/PrivilegedHelperTools
Can you please run this in the Terminal:
ls -al /Library | grep PrivilegedHelperTools
And let me know the output?

Cheers,
Carlo
