Also I seem to recall you can do an outb (even from grub) that will just turn off the nv96 card entirely. </blockquote>So I denied pci to enable the card, but nothing changed: with noaccel, screen is still corrupted and without it, I still don't boot, getting lots of errors. Oh, I forgot to precise: the screen gets scrambled just after the handover from efifb to nouveaufb. <blockquote id="DWT247" style="border-left:2px solid rgb(16, 16, 255);margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"> pstore if you have efi, netconsole, blockconsole. And phone isn't so bad either :) Yeah, so all these things should only be necessary if you have acceleration enabled. I wonder if the card comes up in a funny "I'm still executing stuff" state and nouveau fails to "shut it down" when noaccel is passed in. </blockquote>Well, from what I saw in nouveau_accel_init, it just enables things if noaccel=0, and does nothing otherwise; noaccel isn't used apart from accel_init. <blockquote style="border-left:2px solid rgb(16, 16, 255);margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"> -ilia </blockquote>Pierre </div></body></html>
