I've seen the "inux" thing in the past, but by pressing a key shortly after the screen turns back on the system continued to resume as usual. Given that the backlight normally turns back on for you maybe this post method isn't the correct solution for your card. Mine wouldn't even turn on the backlight. > > If you would like me to do more debugging, I would be more than happy to > do so. What is the behaviour when the framebuffer is not enabled? If in that case it doesn't work out of the box, does it work with a userspace trick like vbetool? -- Michael Marineau marineam@engr.orst.edu Oregon State University --------------enig25B8D574476E0B69467C0E7B Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDEWtFiP+LossGzjARAvnhAKDHNNl8vAH9En+YYrbCjM/FknO2UACgta52 uF9wG8FH+kBH41f2MUV3J20= =M6a6 -----END PGP SIGNATURE----- --------------enig25B8D574476E0B69467C0E7B--
