Why is mouse freezing in FreeBSD 9.1 Gnome or Fluxbox?

I'm new to FreeBSD 9.1 and I wanted to install a desktop GUI environment. I first tried Gnome 2 since I am familiar with it. I appended the following lines to the /etc/rc.conf file: hald_enable="YES" dbus_enable="YES" gnome_enable="YES" gdm_enable="YES" When typing startx for the first time, my mouse, keyboard and everything else worked fine. However, after restarting my PC, the mouse didn't work anymore. Keyboard worked fine. I searched around for solutions and people said that adding the following line to the /etc/rc.conf file mouse_enable="YES" or moused_enable="YES" worked for them. However, this didn't work for me. I then tried switching to Fluxbox just to check if that works. I appended the following lines to the /etc/rc.conf file: hald_enable="YES" dbus_enable="YES" Again, when typing startx for the first time, my mouse and keyboard worked fine. However, after restarting my PC again the mouse worked just before starting X (in text mode). However, after starting X it doesn't work at all. Keyboard works fine. Does anyone have an idea what might be causing this kind of behavior and how to fix it?
