How can I install a minimal GNOME desktop on F22 Server?
In Fedora 22 Server I can install a minimal XFCE Desktop with the command 'dnf groupinstall "XFCE Desktop"' - this pulls down XFCE, Thunar and LightDM with not much else. To install GNOME you have to pull down the "Fedora Workstation" group, which also brings down a ton of additional packages such as Firefox, LibreOffice etc...
How can I achieve the same level of minimalism with GNOME instead of XFCE i.e. I just want gnome, gdm and the usual graphical administration tools without the extra applications.
There is no group for what you want. You will have to install the packages manually (gnome-desktop, ....
dnf groupinstall 'Fedora Workstation'
will install the entire Gnome Desktop with all apps.I'm aware there is no existing group to do this - I've attempted to install the essentials like this:
dnf install @base-x gnome-shell
But it runs once and then on reboot it hangs at "Loading User Manager for UID x", additionally it doesn't appear to set up Plymouth. I'd install the individual groups but it seems a lot of the apps are tied to the "Fedora Workstation Core" group.
Which UID is it hanging on? If you're trying to run Gnome, you're using gdm, and that claims UID 42 on my machine. (I no longer use either Gnome or gdm, but the entry's still in /etc/passwd on this box.)
Yes it's UID 42
OK, I have gdm claiming that UID on two different computers, so I think that's established. I'm not sure, as yet, what the next step is, but I think we can presume that the issue is with gdm.
