Recommended Video Memory (vRAM) Settings
When you create a Linux virtual machine in vSphere Client, configure the vRAM size as shown in Table 1-2.
Set the vRAM size that is recommended for the number and resolution of the monitors that you configure
for the virtual machine.
These vRAM size recommendations apply only to virtual machines that are configured to use 2D or vSGA
graphics, which use the VMware driver. vDGA and NVIDIA GRID vGPU use NVIDIA drivers. The vRAM
size set in vSphere Client has no affect on vDGA or NVIDIA GRID vGPU machines.
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 configured with a single monitor
at the lowest resolution.
If a Linux virtual machine is configured 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
Autofit might fail to work. The desktop is then displayed in a small area of the screen.
CAUTION Horizon 6 does not automatically configure the vRAM settings on Linux virtual machines, as
happens on Windows virtual machines. You must configure the vRAM settings manually in vSphere Client.
