Ok, I think this issue will be solved in a few days ! Thanks to you, I finally found the magic lines.
My laptop is : Asus-VivoBook-ASUSLaptop-X421IA-M433IA The command "sudo i2cdetect -l" return theses lines : i2c-3 smbus SMBus PIIX4 adapter port 1 at 0b20 SMBus adapter i2c-1 smbus SMBus PIIX4 adapter port 0 at 0b00 SMBus adapter i2c-6 i2c AMDGPU DM aux hw bus 0 I2C adapter i2c-4 i2c AMDGPU DM i2c hw bus 0 I2C adapter i2c-2 smbus SMBus PIIX4 adapter port 2 at 0b00 SMBus adapter i2c-0 i2c Synopsys DesignWare I2C adapter I2C adapter i2c-5 i2c AMDGPU DM i2c hw bus 1 I2C adapter And now, to turn on the numpad I use this command : sudo i2ctransfer -f -y 0 w13@0x15 0x05 0x00 0x3d 0x03 0x06 0x00 0x07 0x00 0x0d 0x14 0x03 0x01 0xad And to turn the numpad off this one : sudo i2ctransfer -f -y 0 w13@0x15 0x05 0x00 0x3d 0x03 0x06 0x00 0x07 0x00 0x0d 0x14 0x03 0x00 0xad As I told before, I succeed to turn it on with the "all ports test" command but wanted to know the good one and I started to test 1 to 6 but could not guess it was 0 ! I really think that there is no hardware to handle the numpad since without the correct driver installed, there is no way use the lightpad. So, i'm sure there is a little program running in background to detect the zone pressed in the numpad and display the corresponding number. Someone already wrote such a program and if I could get it work, I would have printed numbers on a transparent sticky paper and place it on the numpad. But people who succeed in turning on the numpad will probably make us a kind of .deb to install and get this thing work ! I trust you ! Whatever, many thanks for this hack ! Even if I can't use it for now, I can give the illusion that Linux do the job too ! :-) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1810183 Title: numpad on touchpad doesn't work in ASUS Zenbook 14 Status in Linux: New Status in linux package in Ubuntu: Confirmed Bug description: I have Asus Zenbook 14 UX433FA which I have installed Ubuntu 18.10 alongside windows 10. The numeric keypads are within the touchpad and are supposed to be turned on by a button on the touchpad. This works well in Windows but doesn't work in Ubuntu. I have tried to search for any related problems/solutions online but I haven't been able to. I will appreciate any suggestion or help.
