I recently successfully installed Arch Linux in VirtualBox, for the first time. I want to install FVWM, so I installed X Server, and then ran pacman -S fvwm. It says that fvwm has been installed, but the terminal still stays there and there is no windowing. I know I am probably doing something stupid, but I'm not sure what. Please tell me what I am doing wrong.
Update: I installed GDM. When I select "fvwm" in the menu and enter my password, the screen turns black, several console messages with a green "okay" status to the left appear, the screen goes black again, and then it turns gray and returns to the login screen.
