Ok, I think same. In KDE4 I see some loop/noop operation when new=20 dell keyboard backlight driver is used. Key KEY_KBDILLUMTOGGLE=20 cause that BIOS change brightness and also KDE4 see it and change=20 it too... Similar problem there is with KEY_WLAN and NetworkManager. Gabriele, can you create patch which disable both KEY_WLAN and=20 KEY_KBDILLUMTOGGLE in dell-wmi.c driver? =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart2151401.pXY5CEKPAf 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) iEYEABECAAYFAlR/DvwACgkQi/DJPQPkQ1InxACfS/kFb4SLvA6uhv0vL5gK2teL 59sAn18jezaHxSUWkzF3M8f4/u8cSd9x =W8Ht -----END PGP SIGNATURE----- --nextPart2151401.pXY5CEKPAf-- -- 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/
