Work to provide selection of the preferred screen, and positioning, relative to the preferred screen, of other screens in lxrandr is underway.
As lxde is a metapackage for the lxde suite, which includes the as-yet incomplete (in terms of desired functionality) lxrandr, and this functionality is available through the command-line tool xrandr, and perhaps the suggested arandr, I'd recommend not changing the dependency of lxde on lxrandr, but suggest perhaps adding a Recommends: or Suggests: to lxrandr packaging to those other tools. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
