Text screen becomes graphics

[Tuc at T-B-O-H]

Hi,

        I'm running:

FreeBSD toshiba.tucs-beachin-obx-house.com 4.11-STABLE FreeBSD 4.11-STABLE #8: Mon Aug  1 12:08:53 EDT 2005     root@
toshiba.tucs-beachin-obx-house.com:/usr/obj/usr/src/sys/TOSHIBA  i386


        I'll be in a text window, no X running, and not doing anything
complicated, and all of a sudden I'd get the screen looking like a bar code.
I can't figure a way to clear it. If I start X, then exit out, its still
seeming to be in graphics mode.

        Any idea whats happening?

                        Thanks, Tuc
