I was wondering if anyone could help me with this small problem that I have been having. I recently bought a Lenovo X230t and promptly installed Ubuntu 13.04 on it.What I have been trying to do since is map the screen rotation to a button. I have done this; my problem is that screen rotation is also mapped to button with keycode 154. Also weird, pressing button 154 does not trigger an acpi event; I have absolutely no idea as to what is causing this. If I remap key 154 using xbindkey while I am using my laptop, this problem no longer persists. Once I restart though, it is back again. Thanks to all that help in advance.
