I'm currently forced to work with a machine running Red Hat Enterprise Linux 6. Since I'm usually working with the latest Ubuntu version and a corresponding modern desktop environment, I was quite disappointed that RHEL 6 by default only supports gnome and KDE versions from 2009. Working in any of them is just painful and feels like a time travel to the last century.
I'm not allowed to upgrade to RHEL 7 or install a different OS, but I have sudo privileges.
Is there a way how I could get any modern desktop environment up and running without an OS upgrade? I don't even care which one, I'd just like to have a version that's not 6 years old...
