I'm having identical desktop crashes on multiple computers in my classroom (I'm a teacher in elementary school) Xterm works fine but Terminal (/usr/bin/Terminal) crashes X everytime. I'm unsure of how to change the bitmode of my video card as a workaround as suggested by Martin. I'm also unsure as to whether the applications menu is editable to remove or repoint the Terminal launcher to xterm or another alternative. Here's my /var/log/messages from the point I invoked the command 'Terminal' in xterm... As you can see it caused a full crash and I had to hard-reset the machine.
