If I run xrandr -q after I set the monitors, both KDE and openbox give the same output:

Code: Select all

Screen 0: minimum 320 x 200, current 2624 x 900, maximum 32767 x 32767

It seems that KDE treats both screens as one for some reason, but openbox uses separate screens. Also, if I run "systemsettings" under openbox and click the "Identify outputs", the same thing is produced like the screenshot. I am not sure if this is caused by some KDE thing, but this is the only way I know that can identify screens.

Ok, sum up:

1. configuring a boxed screen layout indeed *does* work
2. as soon as you start the krandr systemsetting, the mode is reverted to cloning - KWin or Openbox
3. "KDE treats both screens as one for some reason"
- How does that manifest (precisely)?
- Please post the output of "qdbus org.kde.kwin /KWin supportInformation" while under KDE the screens are coufigured in a row, ie. the last provided xrandr ouput holds.

I am not sure what describes a boxed layout, but the behaviour is:
1. By default the screen layout is clone
2. In KDE, if I set the VGA1, for example, to "Right of" LVDS1, then the desktop is streched into two screens. The most distinctive behaviour is that if I maximize the window, it streches to two screens as if it does in one big screen. That is what I say "treat both screens as one".

The following are the outputs of

Code: Select all

qdbus org.kde.kwin /KWin supportInformation

Before I change anything, i.e. VGA1 "clone of" LVDS1:

Ahh, I found "Multi-head: no" using vimdiff. Is that the problem?

Multihead is sth. different.

Your problem is this:

> Number of Screens: 1
> Screen 0 Geometry: 0,0,2624x900

KWin gets this idea from QDesktopWidget, what makes me think Qt was compiled w/o xinerama support.

Notice that "KWin version: 4.10.5" despite you claimed KDE 4.11.3 - threre's something wrong here as well.

Oh, I downgraded KDE to stable version for testing, so now it is 4.10.5...I will check QT too

OK, I think I can mark it solved! I added xinerama USE flag to global and recompiled everything with xinerama, and suddenly everything works! I did not know it is the problem of "qtgui" though...

you're not supposed to know such (you can't)
users usually file bugs against whatever does not work and have developers pass the blame down.

(of course the better you know what to blame, the faster it can be dealt with)

Yeah...but developers can't always reproduce this problem...So I have to find it myself..

not reproduce, but find it from your information
