I fixed my issue! After trying the commands you suggested to me (thanks by the way) I tried the command sudo nvidia-xconfig which backed up the existing xorg and created a new one, and I used startx to boot back up and it worked fine (albeit at 640x480) Thanks again

Chromecast a tab, then separate the tab into a new Chrome window (drag it out). Go back to the original Chrome window. Now, you've got a virtual second screen. Not sure if that's what you were looking for, but that's what I came up with to get my second screen. It works for what I was trying to do -- see two screens.

display settings doesn't have much with BIOS settings, to change output from mirror to dual screen you have to go to "System Settings" then to "Display and Monitor" (I think that it has same name in Ubuntu and Kubuntu), click on monitor and set resolution and position (drag second monitor icon to the left or right of first one). There you have also an option ...

You could install arandr. Use arandr to set up your screen. Then save the screen configuration to a script. Create a new Application Autostart item and copy the command from the script there or you could set the script to run at startup.

About a year after I posted this question, and after testing on other linux distros including Kubuntu, I can now confidently say that the Nvidia drivers were not the issue: disabling intel proprietary microcode drivers solves the problem.

Good news! The display adapter works seamlessly for Ubuntu 14.04. I had to go to the display settings and force Ubuntu to recognize the monitor to which the display adapter was connected.

The ASROCK IMB-150 has a lvds connector on the board, with no monitor connected it defaults to the LVDS, despite LVDS being disabled in BIOS. Disabling the LVDS and enabling the VGA port forced the output out the correct video port. adding consoleblank=0 solved a problem with the console not returning after the screen was blanked. /etc/default/grub ...

Thanks. Jacob's solution is just what I was looking for. <screen> is meant to replace the specific input that you need to provide to xrandr. To find out what that name of the input is, look at the first acronym that appears just before the list of numbers when you run xandr. In my case these were LVDS1 and VGA1 (the first is my laptop, the second ...

Looks like you need a custom modeline for your display (Basically a custom "output"). Either that or your drivers aren't working properly... I had this issue with an old monitor and a custom modeline sorted it right away :P You can add the native resolution modeline (1920x1080_60.00?) and then you should be able to switch to it, any other resolutions will ...

You need to look at xrandr command May be something like: xrandr --output SCREEN1 --output SCREEN2 --output SCREEN3 --same-as SCREEN2 where SCREEN3 mirrors SCREEN2. Replace SCREEN1, SCREEN2, SCREEN3 with the appropriate name that you get with the xrandr command (without any option). For example, LDVS1, HDMI1, VGA1, etc ...
