No Mouse cursor with 8.1 (and workaround)
Hello,
I am facing the issue, that there is no visible mouse pointer at all (I had extra big mouse pointer "inverted" as my initial setting) on the DisplayLink display. I have Windows 10 Pro 64-Bit on a Dell D830 (8GB, Core2Duo T9300) with extra USB 3.0 ports in the ExpressCard slot, where the DisplayLink is connected to. I tried all available mouse-pointers, but the cursor remained blank. The only way I could get the mouse-pointer to show was to switch on the "mouse trail" in the windows settings (with the shortest possible mouse trail setting available). Then also all the available Windows mouse pointers all work. Maybe this is some problem with the initial different settings (extra big, inverted), that I had? Speed of the Mouse pointer with 8.1 Alpha is almost back to pre Anniversary Update speed :-), probably still a little bit slower. |

Updated to Alpha 8.1 M0
Update worked fine - but I still see the mouse only with activated trail.
Speed (for my surely outdated config with Core2Duo only) is still more laggy than with the 7.x drivers before the Anniversary Update, but at least somehow useable now. |

No Mouse cursor with 8.1 M0 Driver
As others users reported with 8.1 Alpha version of the driver http://www.displaylink.org/forum/showthread.php?t=64975 I have no mouse pointer after installing the new driver.
As they said, the only way to show the mouse-pointer is to switch on the "mouse trail" in the windows settings. Two months waiting for the update that solves the mouse lag and it is unusable |

Hello,
I missed your message, I am sorry. Would you please be able to provide the log files as described in my signature (3rd link) and post the ZIP file from the Customer Support Tool? In order to progress, we need to setup a reproduction in house. Could you try to add the following registry key, if you know how to do this? I would like to gauge the impact. Code:
Key: HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\Core Value: LowLatencyMouseCursor Data: false Data type: REG_SZ Alban

It works. Mouse is still laggy but adding this registry key solves the cursor visibility problem.
Thanks a lot, Alban |

Thank you for testing this.
This key simply disabled the work done to change the way the mouse cursor was handled. I am very sorry this was not developed properly. We did test it internally before we released the change, and I don't yet know why this doesn't work for some machines when we did not have the missing cursor on any internal machine we tried on. Would you please be able to generate ZIP file of your logs with our Customer Support Tool as described in the last link in my forum post signature? We need to reproduce the issue to understand what is going wrong and selecting a machin as close to yours as possible will be key. Kind regards, Alban

Tue-Tue,
Thank you for the logs. It has helped us select the machine to setup the reproduction. Once I have an update from the engineering team, I will share it here. Kind regards, Alban

Hello,
Root cause has been found. Some graphics cards put the wrong depth (they set it to 0) on the surface. Instead of simply using the depth value given, we will gather it from somewhere else if we're told it's 0. We're implementing the change and will have to test it. Kind regards, Alban

Hello,
The fix for that is now available from 8.2 Beta onwards. http://www.displaylink.org/forum/showthread.php?t=65140 Kind regards, Alban
