Configure dual monitors in Suse 11.3

[Jonny88]

Hi

I've finished a new build recently and I'm trying to get dual monitor support enabled in Suse 11.3

Previously I had this in Suse 11.2 using a dedicated NVIDIA graphics card with VGA and DVI output and this was done in a GUI. I now have 11.3 and a built in ATI card with VGA and DVI output

When I run xrandr I get the following

Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192
VGA-0 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x 255mm
   1440x900       59.9*+   75.0  
   1280x1024      75.0     60.0  
   1280x960       60.0  
   1152x864       75.0  
   1280x720       60.0  
   1024x768       75.1     70.1     66.0     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-0 connected (normal left inverted right x axis y axis)
   1360x768       60.0 +
   1280x720       60.0     50.0     60.0  
   1024x768       60.0  
   800x600        60.3  
   720x576        50.0  
   640x480        60.0

Changing down to 1024x768 makes both screen viewable, but at the wrong resolution. I want to set DVI-0 to 1360x768 but keep VGA-0 as 1440x900

How do I do this?

I tried using xrandr --screen 1 but it says

Invalid screen number 1 (display has 1)

I'm looking to expand the desktop onto the second screen so I can photo edit on one screen and web browse and instant message in the other screen

Currently using the Radeon R600 classic driver from ATI

Many thanks
Jonny

I have made some progress on this now using the following commands;

xrandr --output DVI-0 -s 1360x768
xrandr --output VGA-0 -s 1440x900
xrandr --output VGA-0 --primary
xrandr --output DVI-0 --right-of VGA-0

This worked quite well, except my desktop unexpectedly jumped over to the second monitor (ie the taskbar, systray, icons, widgets etc) so I had to move them back by hand as I couldn't find a better way to do this. Now on reboot all the desktop widgets have disappeared and I have to run all the xrand commands again to get back to normal. How can I commit what I have done to be defaults?

Put them in a script.

Hi,

I've made my script, called it "Display" and saved it into my home folder, here is my script

    #!/bin/bash
    clear
xrandr --output DVI-0 --auto
xrandr --output VGA-0 --auto
xrandr -r 75.0 
xrandr --output VGA-0 --preferred
xrandr --output VGA-0 --primary
xrandr --output DVI-0 --right-of VGA-0

How do I make this run at start-up instead of having to run it myself?

I'm surprised there isn't an easy way to save settings like this in Suse. Why did they get rid of Sax! it worked much better than this.

Thanks
Jonny

You can still make a xorg.conf file by hand You can use the propritary drivers config utility to produce one and then hand edit it.

No one wanted to maintain sax2 anymore. You can still install it but it may not work well.

If using KDE4, you can add your script to your user 'Autostart' directory

~/.kde4/Autostart/

Right-click on your script file, and select properties, then make it executable (under the permissions tab).

Then via System Settings, navigate to

Advanced User Settings > Autostart

and make sure your script is listed. If not, add it.

Then restart your desktop (CTRL-ALT-BACKSPACE twice), and your script will execute after login.
