Hi Kay-Heng, sorry for the delay, I'm currently on the road a lot. I added the above, which makes ubuntu display the big icon for disabling the touchpad when pressing only the Fn button. I tried finding the correct modifier. Unsuccessful yet.
I thought that explicitly defining the Fn button as the "function button" would solve this, and yes.. The error is gone with the following config: evdev:atkbd:dmi:bvn*:bvr*:bd*:svnStandard*:pn* KEYBOARD_KEY_f8=fn BUT this does NOT solve the key combination Fn+F5 to toggle my touchpad. Although other functions, like brightness controls (Fn+F11 and Fn+F12) and sound control (Fn+F8 for mute, Fn+F9 lower, Fn+F10 higher) all work, even without this configuration. So nothing gained, yet. I figured that finding the keycode for the combination of Fn+F5 would be the next step and this is what I've found so far Without the extra configuration I've used showkey -k keycode 125 press keycode 29 press keycode 85 press keycode 85 release keycode 29 release keycode 125 release Where the following is produced when I add the above configuration again: keycode 464 press keycode 125 press keycode 29 press keycode 85 press keycode 85 release keycode 29 release keycode 125 release keycode 464 release Would this help in finding the correct modifier/configuration? -- 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/1813783 Title: Unable to toggle Touchpad by keyboard shortcut Status in linux package in Ubuntu: Confirmed Bug description: Pressing Fn+F5 button should toggle the onboard touchpad. This seems not to work and might be related to the following bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/717931 After pressing Fn+F5 shows the following: $ dmesg ...

I've added the mentioned kernel parameters as described in https://wiki.ubuntu.com/DebuggingACPI (adding acpi=off) and https://bugs.launchpad.net/ubuntu/+source/linux/+bug/717931/comments/21 (i8042.nomux=1) but the problem still exists. Touchpad also has a little dot in the upper left side which I assume also is for toggling on/off the touchpad. This is also unresponsive. How reproducible: Always Steps to Reproduce: Press Fn+F5 Actual results: Touchpad is not working Expected results: Touchpad should toggle on/off, making it able to use the touchpad.
