This article explains how to configure Linux to select the preferred desktop for Linux VDA sessions.
For Linux, the login screen provides the options to allow end user to select their preferred desktop which is shown as below.
However, there is no login window shown if an ICA session was launched after installing the Linux VDA. The end user login to the system automatically so they cannot select the preferred desktop environment.
The desktop environment can be selected by creating a new file called “desktop” under the path “/etc/sysconfig/” with the following content. Take selecting “GNOME-Classic” in CentOS 7.2 for example.
DESKTOP=”GNOME-Classic”
DISPLAYMANAGER=” GNOME-Classic”
Save and close it after creating the file. The change will be applied after logoff/logon the ICA session. The screen shot shown below is a GNOME-Classic one.
Replace the “GNOME-Classic” into “GNOME” in the file and logoff/logon the ICA session. GNOME desktop environment is applied as shown below.
This method also works for KDE desktop environment.
