Getting dual monitors to work on Gnome 2.26.1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello All,

I am trying to get dual monitors (2 identical HP L1940T) working on my machine but I am not having any luch at all.

I am not having the 2 screens as one virtual screen as it's mirroring one other currently.

I go to System -> Preferences -> Display, I can see the "Mirror screens" check box checked.  So I uncheck this box and click Apply, then I get a pop-up saying
"Monitor Resolution Settings has detected that the virtual resolution must be set in your configuration file in order to apply your settings.

Would you like Screen Resolution to set the virtual resolution for you? (Recommended"

When I answer "Yes" to this and get the following error:

"Your settings cannot be applied because the virtual resolution is not big enough to contain your screens"

So I am really stuck at this point so I turned to Google for help and found there are couple of people had the same problem but unfortunately the found no resolution.

I was wondering whether any of you guys will be able to help me resolve this issue.

Here are the details.

Also can anyone please tell me what is the configuration file Xorg uses these days?  My /etc/X11/xorg.conf doesn't have much info at all, this is all I could find in there:
Section "Device"
    Identifier    "Configured Video Device"
    Option        "UseFBDev"        "true"
EndSection

Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
EndSection


Thanks in advance.
