Setting Up for Linux Desktops

Virtual Machine Settings for 2D and vSGA Graphics
When you create certain Horizon 7 for Linux virtual machines, you must change the memory seings and
conguration parameters to the minimum values recommended.
Virtual machines that are congured to use NVIDIA vDGA use the NVIDIA physical graphic card. Virtual
machines that are congured to use NVIDIA GRID vGPU use the NVIDIA virtual graphic card, which is
based on the NVIDIA physical graphic accelerator. You do not need to change the Video Memory (vRAM)
seings and conguration parameters for these virtual machines.
Virtual machines that are congured to use 2D or vSGA graphics use the VMware virtual graphic card and
you must change the following seings for these types of virtual machines:
n
Video Memory (vRAM) seings
n
Conguration parameters
n
3D Memory seings
n
vCPU and virtual memory seings for performance requirement
Video Memory (vRAM) Settings
When you create a Linux virtual machine in vSphere Client, congure the vRAM size as shown in Table 1-8.
Set the vRAM size that is recommended for the number and resolution of the monitors that you congure
for the virtual machine.
Table 1‑8. Recommended vRAM Settings for 2D or vSGA Graphics
vRAM Size
Number of
Monitors Maximum Resolution
10 MB 1 1600x1200 or 1680x1050
12 MB 1 1920x1440
32 MB 1 2560x1600
48 MB 2 2048x1536
80 MB 2 2560x1600
128 MB 3 2560x1600
128 MB 4 2048x1536
These vRAM sizes are the minimum recommendations. If more resources are available on the virtual
machine, set the vRAM to larger values for improved video performance.
10 MB is the minimum vRAM size recommendation for a machine that is congured with a single monitor
at the lowest resolution.
You must power o the virtual machine to set the number of displays and the amount of video memory to
use, as described in “Create a Virtual Machine and Install Linux,” on page 19.
Horizon Connection Server 7 does not automatically congure the vRAM seings on Linux virtual machines
like it does on Windows virtual machines. You must manually congure the vRAM seings in vSphere
Client.
If a Linux virtual machine is congured with a smaller vRAM size than is recommended, the following
issues might occur:
n
Desktop sessions might be disconnected right after the initial connection is made.
n
Autot might fail to work. The desktop is then displayed in a small area of the screen.
