First of all I'm new in using linux and please forgive my bad english.
I have an server with Edubuntu LTSP 10.10, a projector and 20 thin clients. On the server I had to install a video card (nvidia chipset driver 260.19.06) with two ports: DVI and VGA so I can connect the projector on the VGA port. After I installed the driver I managed to configure display settings in twinview clones.
Till now everything is ok but now comes the strange part..until I had to install the video card when users login on thin clients their display was normal but now it is mirrored and upside down and I don't know what happened. Can anyone please tell what to do get display to normal?
