The reason I mentioned ssh is: if you start X under gdb from the
console, the X server will switch away to a new virtual terminal while
it initializes. Then, when it crashes, it will halt in gdb; but you
won't be able to switch virtual terminals back to gdb, because X has
put the vt into process mode, and is now halted under gdb so it can't
run the code to release the vt back to the kernel.
