This sounds like your BIOS doesn't know how (or try) to use your graphics card, so all the BIOS output goes to the other display connector (the one of the built-in graphics adapter). So the BIOS's own boot messages, the GRUB boot messages, and the early kernel messages all go "unseen" and it's only once the Linux kernel loads your display driver (to get a framebuffer) that finally you start seeing output. > This sounds like perhaps a driver issue of some kind, so what packages > do I need to be sure are No, it looks like it's fine on Linux's side. The problem is the earlier boot environment (the one from which Linux is started). So the fix will need to be somewhere between your BIOS and your video card. Maybe all it takes is to tell your BIOS to use your external graphics card instead of (or additionally to) the built-in video adapter. Stefan
