Was running xUbuntu 18.0.4 LTS and upgraded (re-install via DVD) to Ubuntu 20.0.4. I'd like to get back to the XFCE Desktop as it find gnome unusable for my application. In particular I have a lot of problems with Nautilus but really liked Thunar. These are the File Manager programs.
I attempted to install it (xfce) following an article on Linuxconfig.org which gave the following procedure:
sudo apt install tasksel
sudo tasksel install xubuntu-desktop
This may or may not have installed xfce but it mentions there is then some step to select the desktop to use. Unfortunately I can find no selector anywhere nor do I wish to have go thru the selection process every time I reboot. I am still running "Files" (aka Nautilus) as an app.
Is there any way I can install the XFCE making my system xUbuntu and remove gnome or as much of gnome as is possible? Of course this pertains to Focal Fossa: i.e. Ubuntu 20.0.4. If I have to I can do a new install presuming I can find a xUbuntu 20.0.4 release.
sudo apt install thunar
.xubuntu-desktop
I would have expected you to be asked a question as to which DM you wish to use (ubuntu-desktop
usesgdm3
as the greeter & DM, Xubuntu does not) which will impact how it's selected. The selection is not when you boot, but when you enter your username & password. I suspect you've got all you need, just haven't found out where the selector is on your greeter (which varies on what you selected at a prompt in your second listed command).
