Minimize, Maximize, Close icons are missing in my GNOME desktop of Kali Linux. However, when I click in the place they are supposed to be, they do what they are supposed to do.
Weirdly, Firefox is only missing the maximize icon!
This may have been caused when I tried to install xserver-xorg-input-synaptics. This apparently removed kali-desktop-gnome but I could use gnome even after running the installing synaptics. Anyway, I installed kali-desktop-gnome again (which automatically removed xserver-xorg-input-synaptics but the issue is still here.
PS: I would also like to know if it is possible to install xserver-xorg-input-synaptics without removing gnome because I want to enable my touchpad tap to click (synclient tapbutton1=1) in xfce too.
