Im new to the forum (and linux) and I'm getting a strange issue which I hope somebody may be able to help me with.

I am currently running linux with dual screens in extended mode from a dual screen PCI Express Realtek graphics card. I installed a 2 port PCI Express Network Adaptor and started the machine up and both are working correctly. The issue is that the dual screens are now in clone mode rather than extended and I am unable to change it back. If i remove the network card the screens revert back to extended mode!

Im not sure if this is a common kind of problem with linux or if its as strange to you as it is to me but any help would be much appreciated.

Thanks in advance,
