I bashed my head against the green rectangle for a few hours (TNT card), and finally found the answer in a troubleshooting document I found on irc.openprojects.net, in the #nvidia group from a bot there. Basically, if you have the nvidia fbconsole compiled into your kernel, bad things happen. I don't know about generic vga fbcon; once I discovered this, I just removed fbcon from my kernel and it works fine (except I have an SMP machine, and nvidia seems fundamentally incapable of writing a working non-NT SMP driver). The stock debian kernel has vga fbcon compiled in, IIRC. HTH. > I think it must have something to do with the nvidia driver.

That's the point of the nvidia corp driver: it does all kinds of funky undocumented direct hardware access that makes it use less CPU resources than nv.o, and lets it do 3D acceleration. -- -----------------------------------+------------------------- Change is inevitable. | A n d r e j M a r j a n Progress is not. | [EMAIL PROTECTED] -----------------------------------+-------------------------
