I'm having a laptop with the resolution of 1600x900. When I'm not on the go, I usually use external monitor (1920x1080) as my primary monitor.

I prefer to stick my notifications into the upper right corner of the monitor, like this:


However, when I connect the external monitor, the notification all of the sudden appears to the center of the display:


And when I start to use my laptop monitor only almost the entire popup appears off screen:


Is there a way to make notifications stick to the right edge? This is getting very annoying. Being able to define position of the popup as distance from the right edge of the monitor would be ideal.

Are you manually repositioning these notifications, or is there an applet (Like Colibri) you are using to achieve this effect?

No, I manually positioned the notifications.

Unfortunately manual positioning results in an absolute position being defined, which won't take into account changes in screen resolution, etc. All you can do is file a feature request, requesting implementation of screen resolution sensitive positioning.
