how to extend the view in one monitor to the second monitor


Hi,

I have 2 monitors and I want to expand the view on the first monitor into the second one. Currently the 2 monitors display the same view. I did go to System -> Administrator -> Display (then enter root password) -> Dual head and enabled the "Use Dual head" I got the following message,

You need to log out and restart the X server for the changes to take effect.
Configuration was written to /etc/X11/xorg.conf, original configuration saved as /etc/X11/xorg.conf.backup.

I restarted the machine and tried other ways like ctrl + Alt + Backspace, but I still get two monitors display the same views.

Can someone tell me what the right way to do it? Thanks.


JF

Once you have enabled dual head, you also have to enable the enlarged workspace through both the monitors. Check again in the configuration dialog: you should have something like "Desktop layout", set as "Spanning desktop" (opposite to "Individual desktops").

thanks colucix for the reply. It didn't work for me because my "Dual head" tab always displays "second Monitor Type" and "Second Video Card". How to I switch to the "First Monitor Type"? thanks.

Hi JF, sorry for my late response but I missed your replay. Indeed, you should not switch to the first monitor type: the first monitor and the main video card are configured in the "Hardware Tab". The "Dual Head" tab just queries about the second monitor and the second video card. If you have only one video card with dual (or multiple) output, the second video card field will match exactly the first one. What I was asking is if the "Desktop Layout" entry at the bottom of the "Dual Head" tab is set to "Individual Desktops" instead of "Spanning Desktops": the former will create two indipendent workspaces, the latter will span a single workspace between the two monitor.

If it is already on "Spanning Desktop" maybe you have to tweak xorg.conf by hand.
