Display resolution

The maximum display resolution of the VD environment is 1920×1080 on 2 monitors. If you have a higher display resolution locally and have problems with the display, you should first set the Display: “Large screen” setting in the settings for the virtual desktop pool.

Display protocol

Blast“ and “PCoIP” are used as display protocols in the virtual desktop pools. Depending on the local graphics card used, there may be difficulties with the display. In this case, switch the display protocol in the settings for the virtual desktop pool “Connect via” on a test basis.

Usage rules

Within the VDI environment, the “Terms of Use for the IT Resources of Jade University”, as amended from time to time, also apply without restriction.

Operating system: Apple OS X

  • Right mouse button: Activate the “secondary click” on your Apple Mac OS X device under system settings / mouse. This enables you to use the right mouse button, which is necessary under Windows, in your virtual desktop as well.

Operating system: Microsoft Windows 7

  • Fonts: If you find the display within your virtual desktop difficult to read, you can adjust it under Start / Control Panel (Icon View) / Display / ClearType Text.

Data storage and backup

Due to the central architecture of the system, you may not store any data on the local hard disks of your virtual desktop. Please use the appropriate drives to store your official / university-relevant data. X:\ and Z:\ of the PC-Verbundsystem. These are also subject to data backup.

Private data (if permitted for official purposes) should be stored on USB devices.

Error message: All available desktop sources ... are currently busy

The message “All available desktop sources for this desktop are currently busy. …” is not actually an error message. It merely indicates that all provided virtual desktops of this pools are occupied. This is comparable to a pool room in which all seats are occupied. As a workaround, you can try to use a virtual desktop of another pools.

Integrating local drives

When using the VMware Horizon Client, you can connect drives (USB sticks) locally connected to your PC to your virtual desktop. To do this, move the mouse pointer to the top of the screen within a VD session. The VMware Horizon Client menu appears where you can connect your locally connected devices into the virtual machine. Please do not forget to deactivate this connection to your local devices again before disconnecting from your virtual desktop.

Use from external company networks

If you want to access the virtual desktops from an external company network, TCP ports 4172, 9427 and 32111 (each In/Out) must be opened. If necessary, contact the company's system administrator.

Software client

Please note that we currently operate 2 virtual desktop environments. The older VD environment provides virtual desktops for all university members with Microsoft Windows 7. This system is outdated and will be replaced by the VD environment with virtual Microsoft Windows 10 desktops. Depending on which system you want to access, you must have a different software version of the VMware Horizon Client installed. Further information can be found here.


In virtual desktop environments, just as with standard PC hardware, updates must be carried out at regular intervals and require a reboot. Therefore, users are automatically logged out of their virtual desktops after certain times:

  • For personally assigned desktops: 24h after the last disconnection.
  • For public virtual desktops: 2h after the last disconnection.

Note for users with 2 screens: If you have been logged off from your desktop due to the procedure described above and you log on again, only one screen will initially appear in operation. In this case, you must disconnect from your desktop again (not log off) and log on again.


For the operation of virtual desktop environments, the HRZ reserves the right to adapt and change the corresponding system parts at any time as required to meet the developed requirements. Provided you observe the information given above regarding data storage, this is also not a real restriction, since when a new virtual desktop is provided, the software is provided centrally and you do not store your data locally, but exclusively on the drives of the PC interconnection system.
