Dear all,

I am running the latest Linux Mint 15 "Olivia". Reading this post gave me hope  ;). Two identical DELL 1780FP monitors are in use:
  • My left monitor is connected via standard onboard DVI
    My right monitor uses the onboard HDMI interface and a HDMI-to-DVI-adaptor
Both monitors additionally provide a VGA slot as an alternative, the mainboard provides one onboard output.

Just like odigity posted, both monitors do work - but they show a similar output. I am unable to "share" the desktop across the two screens. Being rather new to Linux Mint (but with some Ubuntu background), this may be due to the operating system. On the other hand, maybe there's some BIOS settings I missed...

Any thoughts appreciated.

Solved!

Long story short: Terminal in Linux

Code: [Select]
xrandr --verbose
xrandr --output HDMI3 --auto --right-of VGA1

added second line to startup-skript - done.

(Got some help from a German board on this topic about xRandR, see http://wiki.ubuntuusers.de/RandR) I posted this to the Intel board - see link above - as well.
