Well, if I do that I won't get my 1280x1024 display under X. I upgraded the video memory on this especially because the 4MB that came with it would not do X at the proper resolution on this monitor. And it does the job. As soon as I put that 8MB chip in there, copied over my XF86Config-4 from the other machine that was using this same monitor, it booted into X like a champ (instead of that wimpy 1024x768 X display it used to give with only 4MB). Much as I'd like to see what effect that would have on this framebuffer failure, I'm reluctant . . . > For the right form for lilo (or in your case grub) arguments, try the > kernel source.

Another item I note in XF86Config-4 but can't tell if it's relevant is that I have; Option "UseFBDev" "true." Could that have any significance? I think I've tried it both with UseFBDev true as well as UseFBDev false and it made no difference. A final stray thought: don't know if you caught my earlier statement about entering atyfb in /etc/modules. I created an initrd that, so far as I can tell, contains this module. However when I boot with the video=atyfb:etc, the module doesn't seem to load. So I resorted to adding atyfb to /etc/modules, after which it started loading and showing up in dmesg--such as in portions I've included in previous messages. Ideally, I should have this module compiled into the kernel, I suppose. But I'm trying to defer anything like that in hopes that I can see if it even works first (e.g., if I have sufficient video RAM to support the resolution I need atyfb for).
