I have Mandrake 9 on a Toshiba Laptop. I can connect a monitor to the Svga port, but I can not get a spanned desktop display.
I tried to declare both monitors and screens and add Option Xinerama on, but it still doesnt work. It gives me an error message saying that there are 2 screens assigned to the same device. :-(

Please help me !!!!! All the documentation out there is about 2 videocards + 2 screens. All I have is 1 videocard with a Svga port +2 screens.


Thanks,

Post your XF86Config file and we can show you what to tweak. For a good example, try looking at this one:

Here is my XF86Config-4. Whenever I try to start the XServer with this, it tells me that I cant have "device1" and "device2" assign to the same hardware. Well I only have one hardware (videocard).

Thanks,

The only thing I can see missing is a screen declaration, compare the above to this:

Hi Finegan,

I add Screen0 and Screen1 but I still get that error saying that XF86Config cannot assign device 1 and device 2 to the same adaptor.

There is any way to make it see the Svga port for the second monitor?

Thanks,
m_m

Is anyboby out there that tried to do a expanded display on a laptop? It works fine in Windows.
I've been reading on linux-laptop.net and nobody tried that Svga output with a second monitor.
I tried to see if the laptop's videocard is a dual-head but scanpci returns just only one video adapter.
Can somebody please help me ??

Thanks,
m_m
