You are right, I was not careful when testing. I tested once more with=20 two different kernels; hibernation works (also in normal init 3) as long=20 as video settings are the same between suspend and resume. If they=20 differ (e.g. plain VGA before suspend and frame buffer after) display is=20 most likely completely garbled (but still is not blank). Of course, any attempt to switch to X (using nv driver) after resume is=20 doomed. OTOH *starting* X after resume seems to work.=20 Sorry for the noise. --nextPart3802586.PxiQHfATqJ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEABECAAYFAkoByS8ACgkQR6LMutpd94yWgwCgjUPHY6uS0pVCJ+LRpGzyuPhj jp8AoJlAvEBF95F03npMOVZM6QoyHMH6 =SwRv -----END PGP SIGNATURE----- --nextPart3802586.PxiQHfATqJ--
