Under X, brightness keys work fine most of the time, but in some case it fails (for example after a dpms force off, but not always). Switching to console and back to X fix the problem for a time. Another weird stuff is that, in single user, I have no way to control the backlight. Using brightness key doesn't work, and /sys/class/backlight/acpi_video0 doesn't do anything. I know there was a lot of enhancements with OpRegion stuff for 2.6.27 and 2.6.28, and it's maybe not finished, but are those problems known? Cheers, and many thanks for the good work :) --=20 Yves-Alexis --=-LefRNLEqLCXADtYXsmfc 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) iEYEABECAAYFAkkvk+QACgkQTUTAIMXAW65RMQCeJi27BshBH8IKa1PnvrgXzq7a GQ8AmgMY9/sFDWzX5+SX5IH3FgX7aOtz =7cCR -----END PGP SIGNATURE----- --=-LefRNLEqLCXADtYXsmfc--
