Default DisplayLink stopped working and now says that I have other USB display drivers

I have 3 Toshiba Dynadocks and 2 Lenovo Thinkvision USB monitors that all use the DisplayLink USB Graphics drivers.

It has all been working great for 6 months until I was in the middle of a PowerPoint Presentation on Thursday using the monitor and the attached message popped up saying that DisplayLink can't install as I am running incompatible USB graphics drivers. Which I am not and haven't been. No idea what caused this.

It has stopped all of my displays from working via USB. I have tried uninstalling DisplayLink and re installing but get exactly the same results. Tried deleting all of the DisplayLink program folders to get rid of any incompatible versions but no difference.

Help!

This is a pain in the bum, I don't want to spend hours trying to figure out what the hell going on, I just want my shit to work like it used to.

Hi,

Regarding the "DisplayLink has detected USB Graphics software installed from a different vendor...." message can you download and run the DisplayLink Compatibility Check Tool from this URL? http://displaylink.com/support/sla.php?fileid=111

When you run the tool it will generate a file called DlCompatCheck.log in the C:\Program Files\DisplayLink Core Software\Debug\ directory. Please attach this file to this post.

Once I see this file I will be able to advise you how to remove the other USB graphics software.

Thanks,
James

Here you go.

Not sure if it worked though, I got the same message about incompatible drivers and them one saying that the check had failed.

Hi,

1. Bring up the Metro interface and type "cmd" (without the quotes)
2. Right click on the "Command Prompt" search result and select "Run as administrator"
3. In the command prompt type "sc delete GManager" (without the quotes) and hit Enter.
4. Reboot and you should be good to go.

Thanks,
James

I can now see the DisplayLink under the USB Display Adaptors and the properties say that it is working but when I try plugging my monitor into the Toshiba Dynadock it still isn't working (the USB ports on it are working fine).

It doesn't show up in Programs and Features as it did before so I don't think that it has installed correctly.

Hi,

OK, please try these steps:

1. Disconnect any connected Dynadocks or Lenovo USB Monitors
2. Download and run the cleaner tool from here:

3. Install 7.6 M1 from here:
http://www.displaylink.com/support/downloads.php
4. Connect any Dynadocks or Lenovo USB Monitors

Let me know how you get on.

Thanks,
James

Sorry but the same as before, the warning message about a corrupted configuration file and DisplayLink doesn't appear in loaded programs.
