Hi, I recently switched from using debian 9 (stretch) to debian 10 (buster). I did this on a new partition of my disk so i think it should be a clean install, and it seems to be.
The desktop manager looks different: i think it is gnome, but i'd like it to be xfce. What i did was to install the xfce4 package, then ran sudo update-alternatives --config x-window-manager switching from (iirc) mutter to lightdm. Then i rebooted. But everything looks the same, so i imagine that my update-alternatives was not the right move, and/or i didn't understand the page i was reading. So my questions are: (1) How can i identify which desktop manager i have? Ideally i'd like to do that with some command line move, like running 'which-desktop' or something like that. (2) Having identified it, how do i change it? TIA for any info! dan
