Mouse pointer disappears on Linux thin client

During my testing phase of XenDesktop 4, I found that when I was accessing my virtual desktops using a Wyse Thin Client I was having issues with the mouse cursor. What would happen is if you moved the mouse cursor from the left screen to the right, and then back to the left screen the cursor would disappear. After some searching, I found that this was a common issue with using the Linux ICA client to connect to XenDesktop. The fix is to apply hot fix XDE400VDAWX86002 to the virtual desktops.

WNOS.ini for V10L Wyse OS with XenDesktop

The following is an example wnos.ini file that you can use for V10L Wyse OS thin clients so that they automatically connect to your XenDesktop infrastructure and automatically launch a desktop group. In addition, when a user disconnects from the desktop group, they’re automatically logged out of the thin client to prevent another user from walking up and launching a virtual desktop that belongs to a user who accidentally forgot to completely log off.
