SUMMARY When I plug on my laptop a screen that I already plugged in the past (like right now I plugged my screen, I unplug it, went away (sleep mode), woke up and plugged again), there is sometimes a gap between the two screens in geometry (the coordinates of one screen do not start where the coordinates of the previous screen end). This is really annoying since the mouse cannot move between the two screens, except if I move it really quickly (I guess if the speed is high enough, the coordinate after the next refresh is on the next screen instead of between the two screens). If I go to the screen settings, I've an error message saying that it is not allowed to have space between the two screens, and I can manually edit that… but it is really annoying since often the mouse is trapped on a screen with no access to the configuration, and changing the config with the keyboard is close to impossible! Also, I don't understand why it does not just pick the same position as before… STEPS TO REPRODUCE This is not 100% reproducible, but here is what I basically do when this happens: 1. Plug a screen to a laptop. Configure it so that the screen is, e.g., left to internal screen. 2. Unplug it, go to sleep mode (not sure if needed), and plug again. OBSERVED RESULT See that sometimes you get an extra space between the two monitors that forbid the mouse from traveling between screens. EXPECTED RESULT No space, mouse should just move freely between screens.

Did you by any chance adjust any of the screens scale factors? If so, this could be Bug 479952.
Or it could be 507702. So additionally, can you paste the output of running `kscreen-doctor -o` when this happens?
Thanks. No, I never played with scale factor. Will try your command when it occurs again.
