Environment
Reflection X Advantage, a component of suite products such as Reflection Desktop for X and Reflection Desktop Pro
Situation
Users of Reflection X Advantage version 16.2 and lower are unable to display the X desktop from newer releases of Red Hat Enterprise Linux and other systems. The following message might be seen:
Figure 1: Error: 'Oh no! Something has gone wrong.
A problem has occurred and the system can't recover. Please log out and
try again.'
This problem exists because newer releases of Red Hat and other systems
incorporate version 3 of the Gnome desktop, which isn't supported in
Reflection X Advantage versions 16.2 and lower. Older releases of Red Hat and
other systems incorporate version 2 of the Gnome desktop, which is
significantly different than version 3.
Resolution
Upgrading to Reflection X Advantage 17.0 will resolve this issue when working with many remote systems. For best results, use a supported version of GNOME 3. Reflection X Advantage supports GNOME 3 version 3.28 or greater contained in the following operating systems (or greater versions of these operating systems):
•RHEL 7.6
•Fedora 28
•Ubuntu 18.04
•SUSE 15 SP2
•Solaris 11.4 SRU24
