Hi
Have an Acer Travelmate 8481G Ultrabook with Windows 7 Pro. Has a built in Nvidia GT 520M. Have a Toshiba Dynadock V (PA3778A-1PRP) (DisplayLink device) Am intermitantley getting flickering on the screen. Only lasts for a second or two. Happens about 8 times per day. Is happening on several systems all same as above. Have just installed the DisplayLink 7.1 M1 driver Same problem. On one unit am running the latest Nvidia driver 310.90 suit GT 520M Notebook. Others have the original Acer/Nvidia driver. (28/1/12 - 8.17.12.9555) Did notice in device manager the DisplayLink driver details 4/9/12 - 7.0.41409.0 Is this correct for 7.1M1? We know it is the fault of the Dynadock / DisplayLink as we have resetup one unit without a Dynadock and worked fine for several weeks. When will this fault be corrected? |

Need the logs just after it happens, and also if there are any events from dwm.exe in the event manager.

Logs as per request
Have discovered something When running diagnostics on KFUltrabook mentions USB 3.0 driver may be issue (logs supplied) Have updated firmware and driver on another unit (TBUltrabook) Then made sure running latest 310.90 nvidia driver Also then updated displaylink driver to 7.1M1 Now I have a different fault Constant screen flashing (rename file to remove .zip off end of file) (see logs and video) If you disconnect the dynadock the display will stop flashing Windows event logs show pretty much nothing |

It looks like the OS is constantly changing the display settings for some reason. That is all I can see in the logs, as they only capture the last changes.
Could you:
Once you've captured the logs, stop the service and disable advanced logging, otherwise it will start to fill your disk up! Thanks Wim |
