On my X230 I also lost the ability to control brightness with Fn+F8 / Fn+F9. With acpi_video I get some interesting sysctl: hw.acpi.video.lcd0.levels: 100 100 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 I guess it should not be 100 100 0 ... 100? Changing brightness with hw.acpi.video.lcd0.brightness doesn't work. --mkHYMT4O8DyWoHkb Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQF8BAEBCgBmBQJUze9dXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ4RjQwMDE3RTRERjUzMTI1N0FGRTUxNDlF NTRDQjM3RDNBMDg5RDZEAAoJEOVMs306CJ1tQ+gH/jEBM3TQ5zrAsvhYKSsYQDVB JMN8//93h62LFwb+Q4GAPlJ1xrQ36X32KAcu1h2ib3dcWYJoU780FP9Q1Nzc7q+D J3TwZ21rLJ2Mzjwgr67UgF2MGAywcRo+HYxbYHUh5ehUzdFFlIXQJ9l0PLfrM7Fg CwGo1AJgqYIONa+ty6/ET05mrgzAQppjaPOc/paR4K3ya9eW9eYQ+Fej4T/b8GbX i6OP4DrcJOMG1Iy8JX5dq35YZjfbF3UX2mg/c8s+hiO5wvRG/jjKUf7/OTkGnqTF en6edSbQwAGsIy8o31cRIlyjjc7wH0zZ38TgG693v+tIhFZIkXU2mq4T6rAkutI= =PvwB -----END PGP SIGNATURE----- --mkHYMT4O8DyWoHkb--
