I've had this problem throughout 3 different XFree86 versions (3.1.2, 3.2, and now 3.2A). Using Linux 2.0.29 (was Red Hat 4.0), a Panasonic CF-41 laptop with C&T65548 video, and the XF86_SVGA server. Mine will SIGSEGV consistently - 9 out of 10 times I switch from X to another tty. This happens both in 8-bit and 16-bit color modes, apparently regardless of what is running. AHHH!! It would be nice if, like everyone else, I could access the virtual consoles while running X. Does anyone have any insight as to the nature of this beast?
