EDIT: As it turns out this is just how gnome is supposed to look and to get a permanently visible dock showing running apps and favorites I must install an extension like dash-to-dock
Thanks everyone to help me understand I was the problem here ๐
After using Ubuntu for years I thought it would be a good idea to try out plain old Debian for the first time.
So I downloaded the live-Image setup a VirtualBox and started installing it... installation ran trough without any problems. But I don't see any panel/taskbar anywhere.
I tried to google this and best guess was that gonme-panel was not installed (how?) after installation I tried to run it by the terminal but it only trows an error "(gnome-panel:3427): GLib-GObject-WARNING **: 20:24:58.712: invalid cast from 'GdkWaylandDisplay' to 'GdkX11Display'". So before I start digging into this I just wanted to confirm that I am on the right track and not just mixing stuff up. So does anyone have an idea what went wrong here?
It seems that how gnome is coming in Debian 12 it is coming without a permanently visible dock. (Yes I know sounds crazy) so there was nothing wrong with the system the error probably just occurred because I (re)installed gnome-panel in an attempt to fix something that was not broken.
