Hi, I.m using centOS 8 in Compaq Pressario V3737TU which is using touchpad. Everytime i pushed touchpad on/off button, i saw an error in messages log, although the button is functioning well, it switch on and off the touchpad. kernel: atkbd serio0: Unknown key pressed (translated set 2, code 0xd8 on isa0060/serio0). kernel: atkbd serio0: Use 'setkeycodes e058 <keycode>' to make it known. I had tried to enter the following commands in command line but did nothing, #setkeycodes e058 0xd8 #setkeycodes e059 0xd9 How can i fix this issue? Best regards.
