You are attempting to use two kext to control the same device winner? Try removing AsusACPIBackLightPanel.kext and see if that clears up the problem. jhawk

First you are talking about two different patches not one. The patch for Function keys fixes the the brightness function keys, secondly the ALS patch enable ALS. As far as the error you will probably need declarations. In general you can take a look at the instructions for UX305FA and see the patches and ref.txt for declaration to get you in ball park. In the directions you want the section to build own dsdt/ssdt SLOW LANE. I'll attach file. Good Luck jhawk

Fnct "A" will turn it off but would require action every time. Take a look at plist I think there is an option to turn ALS off in it if memory serves me correctly. Old Fart memory.... BTW /S/L/E/ AsusNBFnKeys/plist jhawk

Hott,, I found that on the UX305FA that the kext worked fine but the issue was the key code returned by my computer did not match the key code in the kext. Simple resolution was to patch DSDT, Rehabman has a kext ACPIDebug that will allow you to observe actual key codes of your keyboard for the function + key pair. The patches are on the first page of this post. While OsXLatitude has made every effort to make the best product possible, manufacturers make odd changes at times and we must adapt and use patches to overcome obstacles. Please remember this is not "Apple Hardware" and if we wish to have fully supported software / hardware Windows is the only game in town. jhawk

ACPIBacklight.kext causes conflict try it without ACPIBacklight.kext. Two kexts fighting for dominance of same function jhawk

Ref: fn+f5 fn+f6 fn+f7 When you hit Fn+F7 you turn off the display, then sleep via any method. Problem: OS-X needs a display for startup/wake thus ignoring the state imposed by Fn+F7. You can confirm same by simply using Fn+F7 + Fn+F7 (i.e. Turn of display / Turn on display) this will return normal state with functioning ALS post wake up. I hope this helps.... Jhawk

My experience with Asus UX305FA tells me you have competing kexts. ACPIBacklight.Kext by RehaabMan needs to be removed. I would suggest you try it with the following kext. You failed to mention bootloader I use Clover. Only four: ApplePS2SmartTouchPad.kext AsusNBFnKeys.kext FakeSMC.kext VoodooHDA.kext Then identify what is or is not working and resolve one issue at a time. ACPIDebug by RehabMan can be usefull jhawk

EMlyDinEsH EL Capitan upgrade running on the UX305 (requires working Yosemite) Step One download and install Clover xx370 Step Two Delete Kexts directory other than other (ie 10.10 10.11) for clarity KEEP OTHER Step Three download and install config.plist below and place in /EFI/Clover Note: Remember to use SMBIOS settings in your current config.plist (i.e Edit) and keep backup. Step Four download EL Capitan and install For DW1560 users step five and six Step Five delete /S/L/E/BrchmPatchRam.kext Step Six download and install BrcmPatchRAM2.kext and BrcmFirmwareRepo.kext with kext tool. All required files are contained in EL-Cap-UX305.zip EL Capitan Alternate upgrade running on the UX305 (requires working Yosemite) Step One download and install Clover xx370 Step Two Delete Kexts directory other than other (ie 10.10 10.11) for clarity KEEP OTHER Step Three Edit existing config.plist and add the Code below: <key>RtVariables</key> <dict> <key>BooterConfig</key> <string>0x28</string> <key>CsrActiveConfig</key> <string>0x3</string> </dict> Step Four download EL Capitan and install Note: El Capitan USB: The new USB seems to work without the need of USB work around code in Config.plist. Primary testing reveals that most USB devices work as expected with wake and sleep. However, I have observed problems with external SSD to USB adapters. Build quality seems to be the #1 factor. jhawk EL-Cap-UX305.zip

I have an Asus UX305FA the following patches were used by myself, everything works with exception of WIFI Fn Key please note UX305FA fails to have backlight. However, I have been told it works on LN variant with backlight keyboard.

Fn+A disable / enable ALS jhawk

You need to adjust scrolling speed in SysPref | Trackpad

Asus Zenbook UX305FA Ref: Als.patch, AsusNBFnKeys 2.5 ApplePS2SmartTouchPad v 4.4 (latest) TouchPad remains to sensitive at default values for Elan... Unintentional drags and clicks. Palm detection poor / kill touchpad if typing option ? Note have not adjusted via plist AsusNBFnKeys should trip SysPref | Display | ALS checkbox on status change. Reduce brightness to about 6 (dark for old man) in a dark room, desk light only 250 halogen bulb. Problem fails to raise as ambient light increases even with led flashlight indirect light at sensor/camera. Seems slow to react, balancing act to prevent overreaction I assume. Also observed failed to give onscreen feedback of ALS on (auto). as other function keys. Resolved ALS_HAWELL still no onscreen display to indicate status. ALS.patch compiles fine. Thanks for your help wanted to get you feedback asap. As I noted old fart due for cataract surgery next couple months, post allergy season... Update: Just noted AsusNBFnKeys error on shutdown cannot find ALSS repeats numerous times. No ALS-patch in place test via install media clover with updated DSDT. However, AsusNBFnKey 2.5 kext in place. Will everyone patch ALS or do we need trap? Would be glad to test and provide feedback if it would help. jhawk
