+> Using Remote Desktop over the internet will introduce noticeable "lag" (input latency) when compared to local desktop use. This can be influenced by multiple factors including local internet speed and distance from the datacenter where the virtual machine is hosted. This lag does not usually reflect the performance of the VM itself.

 ## Prerequisites
 
 This article requires an existing Ubuntu 18.04 LTS or Ubuntu 20.04 LTS VM in Azure. If you need to create a VM, use one of the following methods:

 ## Install a desktop environment on your Linux VM
 
 Most Linux VMs in Azure don't have a desktop environment installed by default. Linux VMs are commonly managed using SSH connections rather than a desktop environment, however there are several desktop environments that you can choose to install. Depending on your choice of desktop environment, it consumes up to 2 GB of disk space and take up to ten minutes to both install and configure all the required packages.

 ## Create a Network Security Group rule for Remote Desktop traffic
 To allow Remote Desktop traffic to reach your Linux VM, a network security group rule needs to be created that allows TCP on port 3389 to reach your VM. For more information about network security group rules, see [What is a network security group?](../../virtual-network/network-security-groups-overview.md) You can also [use the Azure portal to create a network security group rule](../windows/nsg-quickstart-portal.md).

 If your local RDP client uses network level authentication (NLA), you may need to disable that connection setting. XRDP does not currently support NLA. You can also look at alternative RDP solutions that do support NLA, such as [FreeRDP](https://www.freerdp.com).

 If you don't receive any response in your remote desktop client and don't see any events in the system log, this behavior indicates that remote desktop traffic can't reach the VM. Review your network security group rules to ensure that you have a rule to permit TCP on port 3389.
