I am trying to adjust the screen resolution on my Toshiba Portege 7140CT. I'm sure it's an adjustment in the xorg.conf file, but I don't know enough to do it properly. As a matter of fact, I tried following online instructions only to have no resolution - only lines and a frozen machine. I need this done in the next couple days, please, and would be willing to drive a reasonable distance to have you look at it. If anyone can help me, either by rewriting it for me via email or by my visit to get it done, please let me know here or by calling my cell: 508-713-5947. Thanks! Andrew Wilkin
