sudo su echo 10 > /sys/devices/platform/asus-laptop/ls_level Solves the issue. Issue is related to improperly set ls_level for light sensor on asus laptop. Light sensor could be disabled by entering echo 0 > /sys/devices/platform/asus-laptop/ls_switch
Unfortunately this must be done every restart. I scripted it and added it to modprobe.d default level. To have the fn+F5 and fn+F4 keys back working simply edit: sudo gedit /usr/share/hotkey-setup/asus.hk and paste the following: setkeycodes e005 $KEY_BRIGHTNESSDOWN # Brightness down button setkeycodes e006 $KEY_BRIGHTNESSUP # Brightness up button setkeycodes 6f $KEY_MUTE # Mute key setkeycodes 6d $KEY_VOLUMEUP # Volume up setkeycodes 6e $KEY_VOLUMEDOWN # Volume down setkeycodes e007 $KEY_SWITCHVIDEOMODE # Fn+F7 (backlight on/off) setkeycodes e00b $KEY_VIDEOOUT # Fn+F8 (display switch) -- [Hardy] Backlight low on Asus x57 laptop (M50sa) https://bugs.launchpad.net/bugs/222171 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
