Starting with version 10, Red Hat Enterprise Linux and RHEL-based distributions no longer include a traditional X server. Consequently, the /usr/share/xsessions/ files required by ThinLinc are not available through the standard package repositories. This will lead to the error “No executable profiles could be found” being shown during session startup.
To work around this issue, you must manually create the entries under /usr/share/xsessions. Simply install the desktop environment in question and add the corresponding /usr/share/xsessions/ file, and you will be good to go.
As of writing, GNOME is the only desktop environment that is available under RHEL10 that works with ThinLinc’s X server. Going forward, the availability is likely to improve as more and more desktop environments are added to EPEL.
