On a Lenovo G560
running Ubuntu 14.10 I am trying to connect an external monitor to use as a dual-monitor setup. When connecting the display, the external monitor one mirrors what is on the builtin display. I need it to function as an additional screen.
I have searched for a monitor mirror option in the BIOS, but there is no such related function in the BIOS. From googling I see that on Windows it is said that pressing FN-F3
should provide the user with 4 options:
- 1st option which is already selected is computer only
- 2nd option is duplicate
- 3rd is extend
- 4th is projector
However, on this Ubuntu install I do not get that popup, possibly due to a missing ACPI driver. I have checked in KDE's built-in System Settings -> Display and Monitor
configuration, but the options for configuring multiple monitors are not there. From casual googling I cannot locate the proper driver to install. This is the graphics information in use:
$ lspci | grep -i vga

$ xrandr -q

A colleague with the exact same model laptop and the same Ubuntu version successfully uses his external display as a second monitor. We are both stumped as to why this particular computer only mirrors the display.
