This makes me think that screens are currently sorted with only a "left < right" criteria, maybe total ordering with an additional "top < bottom" could be interesting. (Which makes me think that screen_sort() happens early, thus we should probably check that we do respect Xrandr's rotations even when they happen early / before ratpoison even exists...) > > Then, if a screen is removed, its numset is released.

My lack of knowledge about multiple-screens setups strikes again: do you mean to say that just unplugging a screen makes Xrandr notify ratpoison that the screen went away? I thought that some kind of manual (or preconfigured) intervention with xrandr(1) or any other GUI tool was needed. If not, I'd say that > On the positive side, if the user doesn't add or remove screens, its > screen will keep using the same ids. > > On the negative side, if the user unplug a screen and plug a different > screen, it will have the same id as the previously unplugged screen. Well, if screen A in unplugged from "slot 1" and screen B is then plugged in "slot 1", then I think this is the desired behavior. BTW, do the Xrandr IDs change when you do that? > What's your opinion about it ? Sounds good at first, I think providing a stable ordering for static setups is enough to make current users happy. I'm wondering how much people are relying on sselect. > Thanks, Thank *you* in advance for bearing with me. I'm really a "one laptop screen will do" kind of guy. This Xrandr thingie almost makes me want to buy extra screens just so that I can stop looking stupid. :) -- jca | PGP : 0x1524E7EE / 5135 92C1 AD36 5293 2BDF DDCC 0DFA 74AE 1524 E7EE
