I googled a lot after stumbling on it, and there is multiple bug reports in almost every distro and for Xorg itself without any resolution for many years. The problems stems from the fact that there is no negative screen coordinates in X. 0:0 is always an upper left corner of the leftmost display. Even though xrandr accepts negative values when defining output positions if you look at xrandr -q afterward you would see that it actually puts the leftmost display at 0 and shifts all others to the right. This not a big problem when you screen setup is permanent, there could be some problems with fullscreen games but nothing critical, but as soon as you want you additional, sometimes off sometimes on, monitor to be left one everything goes bonkers. Because every time you connect/disconnect it display coordinates of you main (right) monitor change. And that means that all windows with pinned positions and all maximized windows starts jumping around, you can no longer force programs to start at certain position because that position is different depending on whenever second display is connected or not. So if i would be forced into multiple display on a single screen i will have to set TV as a right display logically, at try to get used to moving mouse to the opposite edge to to move between displays :( -- Nick Koretsky (nick.koretsky@xxxxxxxxx) --------------------------------------------------------------------- To unsubscribe, e-mail: trinity-users-unsubscribe@xxxxxxxxxxxxxxxxxxxxxxxxxx For additional commands, e-mail: trinity-users-help@xxxxxxxxxxxxxxxxxxxxxxxxxx Read list messages on the web archive: http://trinity-users.pearsoncomputing.net/ Please remember not to top-post: http://trinity.pearsoncomputing.net/mailing_lists/#top-posting
