I'm a complete Linux newbie who installed Ubuntu 17.04 (Unity) on his DELL XPS 15 9560 laptop - and subsequently after a bit of playing around messed up the UI.
As you can see, the folders list on the left is very tightly packed now, as well as the ThemeIconsCursorFonts tabs in the Unity Tweak Tool on the right.
Moreover, the drop down menus for the fonts there aren't visually distinct from the background anymore.
This all looked just fine until I somehow messed something up.
Being used from Windows 10 to first of all uninstall a bunch of crap (like games) after a clean install, I
sudo apt remove-d a few gnome things that I thought would be safe to kill, like
gnome-sudoku and a few others, and then went
sudo apt autoremove, which to my surprise seemed to wipe away quite a few packages.
Any idea how I can recover whatever it is that I messed up here?
