I have been trying to get my laptop's media hotkeys working for weeks now, using all the tools (xev, checking dmesg, keytouch, lineakd etc.). Now, I have found a solution and I am now receiving a response from acpi_listen. I have used the keytouch editor to create a keyboard file, but it says my keycode entries are empy. What do I enter here? And how can I get keytouch / these keys which are detected by acpi in xfce?
if a keycode is not automatically detected (most are and called like MAIL, PROG1, NEXTSONG) you need to choose an appropriate one in keytouch-editor when creating the keyboard file. It really does not matter that much how you call a key, but, for example, keytouch automatically gives the button with keycode MAIL the function to launch your mail client.
