Dual Monitor in Ubuntu

General Forums Off-topic Chat

Hey guys. I recently installed Ubuntu onto my computer. The problem is, I’m having a really hard time setting up my dual monitor display. I’d love to get it similar to the dual-view display that is capable in Windows using a Nvidia graphics card. Any help would be awesome!

Well I don’t know others milage on this one but for me I have been using dual monitors on Linux for the last 3 or 4 years and I still end up editing the xorg.conf file manually to get it to work when ever I change distro.

I use 2x 21" Iiyama Vision Master Pro’s @ 2560x1024

This is my /etc/X11/xorg.conf.

/etc/X11/xorg.conf (xorg X Window System server configuration file)

This file was generated by dexconf, the Debian X Configuration tool, using

values from the debconf database.

Edit this file with caution, and see the /etc/X11/xorg.conf manual page.

(Type “man /etc/X11/xorg.conf” at the shell prompt.)

This file is automatically updated on xserver-xorg package upgrades only

if it has not been modified since the last upgrade of the xserver-xorg

package.

If you have edited this file but would like it to be automatically updated

again, run the following command:

sudo dpkg-reconfigure -phigh xserver-xorg

Ensure you have the NVidia proprietary drivers nvidia-glx-new or nvidia-glx-envy first.

I’m using a PCIx NVidia 7300GT as I’m not a gamer and broke.

Running glxgears isn’t that inspiring btw, 2215 fps anyone getting much more with dual screen?

You can have a GUI if you want it.

open a console.

step 1: sudo apt-get install nvidia-settings
step 2: nvidia-settings
