https://bbs.archlinux.org – I have Arch Linux on my laptop, and I have a LCD connected to such laptop.99% of the time, LCD is not used (i.e., it's used, but as TV, not connected to the laptop), so that I work only on laptop's monitor.The problem is that LXDM always appears on the LCD, and this is a problem: laptop's monitor remain black, while LCD is either turned off or set to TV (so that I have to change source on LCD, logging in, then rechange the source of LCD).This is annoying.Why LXDM want to start on LCD?I set correctly my xorg.conf, enabling only one monitor: in fact, after login everything works f (HowTos)
