Description Andreas Kuhl 2013-06-17 10:13:58 UTC

I assigned present windows to top right corner which works well on a single screen 1600x900 (LVDS1) and shows a fancy glowing indicator.

After connecting a 1680x1050 screen (HDMI1) as left screen, moving the mouse pointer to the top right corner of the now right LVDS-1 screen still shows the indicator but the effect is no longer triggered.

Reproducible: Always

Steps to Reproduce:
1. Assign effect to top right corner
2. Connect a second screen with larger resolution as lect screen
3. Move the mouse pointer to the top right corner of the right screen
Actual Results:  
Edge indicator is shown but effect is not triggered

Expected Results:  
Edge indicator is shown AND effect is triggered

please provide output of:
qdbus org.kde.kwin /KWin supportInformation

once for one screen and once for the multi screen setup.

Also please explain how you change the multi screen setup.

Comment 4 Andreas Kuhl 2013-06-17 10:48:57 UTC

I attached the required support information for both single and dual screen setup.

Switching from single to dual screen is done by KScreen/libkscreen2 0.0.92 for which I disabled the "display management change monitor" daemon and enabled the "KScreen 2" daemon. Switching itself works quite reliably,

> Screen 1 Geometry: 1680,150,1600x900

Does it work if you move the screen to 1600x900+1680+0, ie.

    xrandr --output <SCREEN_NAME_HERE> --pos 1680x0

- Is only present windows affected or would activating the desktop grid fail as well.
- Does toggling compositing (Shift+Alt+F12 twice) or restarting "kwin --replace&" have any imoact?

Screen position changed, still does not work.

> Is only present windows affected or would activating the desktop grid fail as well.

Happens with desktop grid as well which is assigned to the lower right corner but I tried to keep the bug report simple and it is likely the same root cause :)

- Does toggling compositing (Shift+Alt+F12 twice) or restarting "kwin --replace&" have any imoact?

No besides that the hotspot indicator does not work with compositing off.

Comment 7 Andreas Kuhl 2013-06-18 11:28:23 UTC

Case solved, this bug report is invalid: Behaviour was caused by synergy (http://synergy-foss.org/de/), works fine without synergyc running.

Sorry for your time... :(

Comment 8 Martin Flöser 2013-06-18 11:35:32 UTC

ah that made my day :-) Hasn't been for a long time that we got a synergy related bug report
