On Rocky Linux 8.5: sudo yum whatprovides sessreg: xorg-x11-server-utils-7.7-27.el8.x86_64
On Rocky Linux 9: sudo dnf whatprovides sessreg: nothing
Was this related to moving to Wayland?
Xorg is still available, so is xorg-x11-server-utils package. I expect it was perhaps deemed sessreg as being deprecated by RHEL.
repoquery -l xorg-x11-server-utils|grep sessreg fails.
I can’t find discussion about it being deprecated or what replaced it. I could compile it but I would rather use the replacement command if there is one.
