Brightness buttons stoped working on Asus Zenbook UX410

Hello everyone,
my brightness buttons used to work but they stopped working, not sure exactly when.

fn+f4 (brightness down) gives with xev :

FocusOut event, serial 36, synthetic NO, window 0x1c00001,
    mode NotifyGrab, detail NotifyAncestor

FocusOut event, serial 36, synthetic NO, window 0x1c00001,
    mode NotifyUngrab, detail NotifyPointer

FocusIn event, serial 36, synthetic NO, window 0x1c00001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 36, synthetic NO, window 0x0,
    keys:  2   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

But on evtest :

/dev/input/event0:	Lid Switch
/dev/input/event1:	Sleep Button
/dev/input/event2:	Power Button
/dev/input/event3:	Power Button
/dev/input/event4:	AT Translated Set 2 keyboard

/dev/input/event8:	ELAN1200:00 04F3:3022 Touchpad
/dev/input/event9:	USB2.0 HD UVC WebCam: USB2.0 HD
/dev/input/event10:	Video Bus
/dev/input/event11:	Video Bus
/dev/input/event12:	HDA Intel PCH Mic

/dev/input/event14:	HDA Intel PCH HDMI/DP,pcm=3
/dev/input/event15:	HDA Intel PCH HDMI/DP,pcm=7
/dev/input/event16:	HDA Intel PCH HDMI/DP,pcm=8
/dev/input/event17:	HDA Intel PCH HDMI/DP,pcm=9
/dev/input/event18:	HDA Intel PCH HDMI/DP,pcm=10

I tested both event4 and event7 but I can't get output.

Any idea ?
Thank you
