To sum up what happens with the different framebuffers on the two cards: NVAC: with efifb+nouveaufb: corruption, with nouveaufb: still corrupted NV96: with efifb+nouveaufb: ok, with nouveaufb: screen freezes So NV96 does not seem to use nouveaufb for outputing, as removing efifb freezes the screen (ie. the machine continues to run, just the screen isn’t updated anymore) and removing nouveau_fbcon_init has no effect. Not sure why NV96 does not use nouveaufb... And NVAC uses nouveaufb (removing efifb has no effect and removing nouveau_fbcon_init causes a screen freeze). I need to do some further tests as removing nouveau_fbcon_init and nouveau_accel_init does not seem to bring garbage screen before freezing. Pierre</div></body></html>
