I have a Mint 10, based on Ubuntu Maverick Meerkat (10.10) installed on a HP nc6120 notebook. The machine is getting tired, so I decided to use it only with the external "monitor", in this case, the TV. I went to the display settings, turned the notebook display off, the TV on, saved it as default and set it.
Somewhy and somehow (no log, no move, no touch, no nothing), the system restores either mirroring or both screens enabled. The whole thing is a mistery, and I'd really like to disable even the possibility of automatic display settings change. I don't mind digging into config files, just please someone tell me how to kill this feature :)
