Mario, do you know if it is possible to "switch" keyboard into=20 mode under which Fn key will send scancode (like Ctrl or Alt)=20 when presses, so it could be possible to use any Fn+key=20 combination for keyboard shortcuts? Because now Fn+F* send one=20 scancode (e.g. suspend key) and other combination of Fn+something=20 does not work... Dmitry, should not Linux follow this Windows input behaviour? For=20 year we have seen people complaining about non working keyboard=20 on Dell laptops under Linux (when user Windows it worked)... Now that BIOS/EC problem is fixed for some dell laptops (probably=20 new versions of BIOSes for other modules will be released too),=20 but it is really bad to see *new* laptop (with broken BIOS) that=20 does not work under Linux (and work under Windows)... =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart2380155.kuSWhSUare Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAlTqCekACgkQi/DJPQPkQ1K1ywCfT6xDkrpSNJBf1rxT1qkc7Q5x E1MAnRb+vXnxTYVVKBpURCfJHZsh3fSM =MyVb -----END PGP SIGNATURE----- --nextPart2380155.kuSWhSUare-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
