Hi, here on a Sony Vaio BZ11XN (Intel X4500MHD), the back light doesn't work (it is @100% at boot, and Fn-F5/F6 do not work). After having followed #258994 (which I encountered too), i came here.
The rc.local/xrandr + manual xbacklight trick works. I didn't try to alter the /etc/acpi/ script yet, but I will. On my up-to-date intrepid, the xrandr --output LVDS --set BACKLIGHT_CONTROL native command works as expected and doesn't produce any error. -- unable to adjust screen brightness on recent Sony Vaio notebooks https://bugs.launchpad.net/bugs/173652 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
