Thank you all for the help so far, I think I'm stuck trying to edit or create a proper xorg.conf file that will give me a consistent display on start up.
I have two identical monitors - Samsung S20D300, Ubuntu 14.04, 4GB RAM, Intel E5300@ 2.60GHz, Nvidia GeForce 8400 GS w/ VGA and DVI-D outputs - 1 monitor connected to each
In Nvidia XServer settings utility, one monitor shows as "Samsung S20D300(CRT-1)" (connected to VGA) the other as "CRT-0" (connected to DVI-D w/ proper VGA to DVI-"D" adapter) Same setup worked fine in Win8.1.
Settings and resolution on the Samsung, are fine, 1366x768, the "CRT-0" is only showing at 1360x768, with lower options available. The 1360 monitor is to the right of the 1366 (main) monitor and the left edge of the 1360 is not visible w/ a black bar on the right side.
I have tried the X.Org Nouveau driver, same thing, using the onboard card + the Nvidia is also out. Installed various legacy and current Nvidia drivers, same.
Using xrandr I was able to force the screen to the right into 1366 and correct position but this of course did not survive reboot. I think I can edit the xorg.conf file but I cannot find exactly how to do that.
Any - all direction, help, questions and suggestions will be very, very much appreciated. Thank you!
