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.

Modifying your primary OS partition

So here’s the scenario that got me into posting this. One of the sysadmins created a new virtual machine in VMWare by cloaning another. The original only had a 20GB drive, but he wanted it to be 40GB. He added the needed space, and then was going to use a partitioning tool to modify the OS partition. Well, he found out that VMWare didn’t like his partition tool and wouldn’t allow it to boot so at that point I pointed out that he could just use diskpart. Apparently he was under the assumption that diskpart wouldn’t allow him to mess with the primary partition… but he soon discovered otherwise. All you need to do to be able to use diskpart to manage your partitions outside of windows is do the following…

  1. Get a WinPE 2.0 disc, or a Windows Vista/7 disc
  2. On the WinPE disc, just get to command prompt, which should be super easy. On the Windows installation discs, you’ll need to select your language, click Install Now, then click SHIFT + F10.
  3. Once the command prompt is up, type diskpart. You’ll then see your prompt change from X:> to DISKPART>
  4. At this point if you don’t know what commands you need, you can go to the below link to read up on it.
