BSOD caused by Credant security software with DisplayLink
Hi.
I just got myself a Toshiba USB Mobile Monitor for my Lenovo X201 laptop. It works great until the next reboot -- then I get a blue screen right after the Windows 7 logo appears. I have to boot into safe mode and use the DL install cleaner to uninstall. Completely reproducible. Tried a dozen times. I've tried the following as well with identical results: - tried DL versions 5.5 (Toshiba CD), 5.6 (DL site) and beta 6.0 - updated my graphics and BIOS to the latest 2011 versions - updated my PC with all the latest windows updates Can somebody help me look into this? I've attached the logs from the DL support tool (was used during safe mode before I uninstalled the DL drivers). Thanks! Last edited by Wim; 09-25-2011 at 04:02 AM. Reason: Updated the thread title to reflect the reason for the BSOD |

Do you have the BSOD dump file? What does event viewer say about the BSOD?

I check the event viewer but it doesn't log anything at the point of BSOD. Maybe because the BSOD happens really early -- seconds after the windows loading logo appears. Ideas? Thanks! |

Hi!
Any possible solutions to this from forum members or DisplayLink? Do I need to provide additional information aside from the first post? My USB Mobile monitor is starting to gather dust. . Thanks! |

Hi
The BSOD is caused by Cmgshcef.sys which is a driver file from company Credant Technologies, Inc. belonging to the product Mobile Guardian Shield. It seems that there are issues in this driver when DisplayLink is installed. We have raised this with Credant, but have not had a follow up. Could you raise this with Credant as a fix would be needed by Credant. Thanks Wim |

I just sent a support email to Credant as well. I hope they get back to us on this. In the meantime, is there a workaround? Perhaps a fast way to disable the DisplayLink drivers whenever the USB monitor is unplugged? |

Hi
I'm afraid there is no quick way to disable DisplayLink. We're a graphics driver and the only way to remove us is an uninstall followed by a PC reboot. Wim |
