[Solved] [xrandr] Maximizing windows the way I want it

I have an external monitor on my laptop. When I plug it in, I start a script to have Dualview for Openbox via xrandr:

#!/bin/sh
# If an external monitor is connected, place it with xrandr
 
# External output may be "VGA" or "VGA-0" or "DVI-0" or "TMDS-1"
EXTERNAL_OUTPUT="VGA1"
INTERNAL_OUTPUT="LVDS1"
# EXTERNAL_LOCATION may be one of: left, right, above, or below
EXTERNAL_LOCATION="right"
 
case "$EXTERNAL_LOCATION" in
       left|LEFT)
               EXTERNAL_LOCATION="--left-of $INTERNAL_OUTPUT"
               ;;
       right|RIGHT)
               EXTERNAL_LOCATION="--right-of $INTERNAL_OUTPUT"
               ;;
       top|TOP|above|ABOVE)
               EXTERNAL_LOCATION="--above $INTERNAL_OUTPUT"
               ;;
       bottom|BOTTOM|below|BELOW)
               EXTERNAL_LOCATION="--below $INTERNAL_OUTPUT"
               ;;
       *)
               EXTERNAL_LOCATION="--left-of $INTERNAL_OUTPUT"
               ;;
esac
 
xrandr |grep $EXTERNAL_OUTPUT | grep " connected "
if [ $? -eq 0 ]; then
    xrandr --output $INTERNAL_OUTPUT --auto --output $EXTERNAL_OUTPUT --mode 1280x1024 $EXTERNAL_LOCATION
    # Alternative command in case of trouble:
    # (sleep 2; xrandr --output $INTERNAL_OUTPUT --auto --output $EXTERNAL_OUTPUT --auto $EXTERNAL_LOCATION) &
else
    xrandr --output $INTERNAL_OUTPUT --auto --output $EXTERNAL_OUTPUT --off
fi

Problem is, after doing that, tint2 is not on top anymore an I can not reasonably maximize windows anymore. The windows would maximize on LVDS1 in that way that a string on the right side is sparred (actually there should even more sparred for tint2, but anyway) and on VGA1 the window maximizes to a small string on the left side of display. The behaviour differs on which program is the window about.
Also the windows I open as kind-windows on VGA1 (e.g. a window for menu in thunderbird) would start in a small space on the left side of VGA1.
How can I tell openbox (or X?) to set the windows right?

PS: I tried to have two instances of openbox running with

DISPLAY=:0.0 openbox
DISPLAY=:0.1 openbox

it works not yet for me.

You shouldn't have two instaces, you're not having different X-screens.

Does openbox play nicely with xinerama information? Haven't used it so I don't know, but such problems tend to be with bad handling of xinerama.

I do not have this option set. I just wanted to tell that I tried this way. It does not matter for that problem.

I do not really get your question: what do you mean by "xinerama information"? I argued a little with xinerama and an xorg.conf but works better without so I do not have an xorg.conf anymore and no xinerama-option set.

Re: [Solved] [xrandr] Maximizing windows the way I want it

witch version of tint2 are you using (tint2 -v) ?
perhaps you can try AUR version (svn-583) and report if the problem is still here.

tint2 ist version 0.11
But I can live with the problems with tint2.
My problem is maximization and that is without panel too.

I'm not talking about actually using Xinerama (its deprecated), but using the xinerama-like information which xrandr passes to the WM. Not sure if openbox supports that.

Re: [Solved] [xrandr] Maximizing windows the way I want it

I am not sure either. Openbox seems to support Xinerama but I do not really get how. Can you tell me how I can use xinerama-like information? How does that work in other window managers.

Update:
I found some Info:

[@ ~]$ xdpyinfo -ext XINERAMA | grep head
  head #0: 1280x1024 @ 1366,0
  head #1: 1366x768 @ 0,0

I do not really know what that should tell me, but I think that the values behind the "@" could be problematic.

Found it here: http://forums.freebsd.org/archive/index.php/t-8226.html
There the solution was to build openbox with libxinerama installed. Libxinerama is installed here.

If it has xinerama support compiled in then it SHOULD work. Try another WM temporarily and see whether it does?

First and foremost, have you set the appropriate options in Tint2?

http://code.google.com/p/tint2/wiki/Configure#Panel

Secondly, where are you positioning tint2? If you're putting it between the boundaries of the monitors, you might have the problem you're describing. Envision your dual monitors as one big rectangle--put your panel on one of the edges of that rectangle.

Re: [Solved] [xrandr] Maximizing windows the way I want it

Offcourse it should work and it does. It was tint2 what did the problem. I startet the script for two monitors without tint2 running and everything was allright. Now I have to think about how to cinfigure the panel.

Solved.
