I finally decided to take the plunge and ditch windows. After several hours I got things working perfectly with all my apps installed. Only problem is that I run 4 desktop displays off 2 nvidia adapters, the first adapter (GeForce GT 240) with two screens work perfectly but can't seem to get the second adapter (GeForce GT 620) installed. Using Ubuntu 14.04 LTS (AMD64)

Please help me with simple instructions please. Terminal info to follow:

    Ha, GOOD question but it is going to get difficult to answer without actually having 2 cards... What I would do: remove all drivers for videocards. Shutdown. Remove 2nd card. Boot. Install driver. Copy xorg.conf over to safe place. Shutdown. Remove 1st card. Install 2nd card in other slot. Boot. Install driver. copy xorg.conf over to safe place. MERGE the 2 xorg.conf. Move it back. Shutdown system. Insert 2nd card. Boot and start praying.

  • The freaky thing is, before I decided on the Standard desktop version I tried the Mythbuntu flavour on a live usb and it supported the two screen adapters out of the box.

    ARM 64 is a typo I guess?
