LXDE Window Manager

Note: This is from a few years ago (@ 2010 perhaps). I'm not sure if it's still necessary, and I no longer have two monitors.

I have a dual monitor setup with two different monitor sizes. Using xrandr let's me use the two monitor setup. Used LXDE's startup application process allows me to load the xrandr configuration upon startup. I'm currently starting the GUI using startx since I don't have something like gdm or kdm installed.

  • First, get the names of the monitors:
$ xrandr
Screen 0: minimum 320 x 200, current 3280 x 1050, maximum 8192 x 8192
DVI-I-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 480mm x 270mm
   1680x1050      60.0*+
   1280x1024      75.0     60.0  
   1440x900       75.0     59.9  
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.1     70.1     60.0  
   832x624        74.6  
   800x600        72.2     75.0     60.3     56.2  
   640x480        72.8     75.0     66.7     60.0  
   720x400        70.1  
DVI-I-2 connected 1600x900+1680+0 (normal left inverted right x axis y axis) 443mm x 249mm
   1600x900       60.0*+
   1280x1024      60.0  
   1440x900       59.9  
   1280x720       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        60.0  
   720x400        70.1
  • Second, save in a shell script called 'dual.sh' in $HOME/bin:
#!/bin/sh
xrandr --output DVI-I-1 --mode 1680x1050
xrandr --output DVI-I-2 --mode 1600x900
xrandr --output DVI-I-1 --left-of DVI-I-2
  • Third, save as a LXDE startup application (I may have extraneous lines in this. Can't remember where I saw how to do this kind of start up script. Still learning LXDE):
$ cd $HOME/.config/autostart/
$ nano xrandr-autostart.desktop
[Desktop Entry]
Encoding=UTF-8
Name=xrandr autostart
Comment=start xrandr with settings
Exec=/home/sean/bin/dual.sh
OnlyShowIn=LXDE
