Linux VDA Ubuntu 18.04 LTS - Grey Screen

Lucas Salamin


Citrix Virtual Apps and Desktops : 19.03

Hypervisor : vmware ESXi 6.7

Guest OS :  Ubuntu 18.04.2 LTS (Desktop)

VDA : LinuxVDA-1903.ubuntu18.04.deb




I'm facing the grey screen problem when I log my Ubuntu 18.04 VM using Citrix Virtual Desktop.


I tried the easy install and the manual procedure (https://docs.citrix.com/en-us/linux-virtual-delivery-agent/current-release/installation-overview/ubuntu.html) but with both I have the same issue.


I tried the following workarounds :




And the one described in the easy install :


sudo apt-get update

sudo apt-get install unity lightdm

Add the following line to /etc/lightdm/lightdm.conf:


Additionnal info :


I switched from gdm3 to lightdm.


In the pam-auth-update the "Create home directory login" option is selected.


The Ubuntu VM is correctly added to the domain and I can log on with AD User credentials (from ESXi Console).

I also can SSH using AD User credentials.


My hdx.log file is attached.


Thanks in advance!
