I just finished installing the latest release of Ubuntu linux on my old Sony Vaio laptop (650 mhz with and intel 815EM vid card)

Basically the entire display is shifted to the left! So the far left of the desktop actually appears on the right side of my display, and to its left is a huge black column, followed by the rest of the desktop. So if I move my cursor all the way to the left, it shows up on the right, and if i move my cursor to the right, it will get to abt 3/5 of the way b4 hitting the black column (where it cant go right any more) and after this is the left side of the desktop.

Part of the desktop isnt being displayed (its off screen) so I cant really read the applications menu, and I cant see the actions menu at all. Does anyone know how to fix this, especially considering the fact that I cant really see the menus?!?! Please help.

Thanks

Ross
