Windows10如何开启鼠标显示指针轨迹

Posted 2021-10-22

最近3D VDI 用户反馈，Windows 10从v1803升级到v1809后，进入3D VDI后鼠标指针丢失，但是功能还是可以用的。又是一个蛋疼的问题。查了Citrix官网，已经是Citrix known issue了，而且在Windows 10 v1809上也很多其它的known issue。具体请参考Citrix官网：https://support.citrix.com/article/CTX234973

目前Citrix官网说正在working with Microsoft解决这个问题，给出了一个workaround，具体信息见下：

Issue 7 - Issue Description

Mouse pointer is not visible within a v1809 HDX 3D pro session. All operations inside the session are to be performed by keyboard using shortcuts. This issue is seen with Citrix XenApp/XenDesktop 7.15 only. This issue is not seen with later versions of XenApp/XenDesktop.

Problem Cause

A change in mouse functionality API‘s is causing this issue.

Solution
Citrix is working with Microsoft to resolve this issue. As a work around, users could enable mouse pointer trails by following below steps:

1. Click Start and type ‘mouse settings‘.
2. Click on ‘Additional mouse options‘.
3. Click on ‘Pointer Options‘ tab.
4. Select the checkbox ‘Display pointer trails‘.
5. Click Apply and Ok.

作为运维人员要么自己帮客户改，要么给客户一个文档，让客户自己改。但是应该还有option3：组策略更改这个配置，google了一下，确实有这个注册表键值。

注册表键值路径：HEY_CURRENT_USER\Control Panel\ Mouse
然后新建一个String Value，命名为：MouseTrails

填写一个键值，键值范围是：1 ~ 7
1 – Minimum length trails.
4 – Medium length trails.
7 – Maximum length trails.

如果想关闭显示指针轨迹，把这个值设置为0即可。
