Comment 13 for bug 1573345

I used to use two screens with outputs on VGA and DP(with converter to HDMI as monitor has only HDMI input) and this worked fine as long as I used it. Now I have upgraded screen and am using two DP where one screen is 4k and other is using DP2HDMI(same screen as used before).

Previous configuration was fine as screens came up quite swiftly but now my 4k screen takes longer to show up and this messes up whole config. (Cairo-dock is showing on left screen in the middle when mouse over right screen's edge etc..).

I believe this whole thing is down to timing when xorg is expecting all screens be ready to accept signal and reply with "Ready" signal but first screen responds faster and second may not respond in time and xorg believes that screen is off or not available so adjust config accordingly.

I don't know what dpms at startup does but I can live with this bug for now as all it does, shuffles my windows all over the place and cairo dock can be reconfigured quickly.

This bug should be submitted to xorg not kscreen I guess.
