> As I said, that may be the panel state rather than the lid switch status. > One last question: What keeps tabs on the "panel state"? Is it the kernel, a kernel module, X, or something else? Would you be so kind as to point me in the right direction? I'd like to find what keeps track of the panel state so that I can disable it (or configure it to lie and say that the panel is always open). Most internet searches for "panel state" lead me right back to the laptop lid switch, which I guess has been a red herring all along. Many thanks, Bruno
