External Monitor display from a laptop solved

Post by StanTheMan »

I have a Toshiba laptop with a parallel port to connect an external large screen monitor. I a dual booting with Vista and Linux Mint Gloria.
When I start up , the external monitor displays the initial verbose and Bootloader screen.
If I select to boot Vista , its desktop loads normally on the external monitor. The Laptop has a button above the keyboard, which if pressed brings up an option dialogue on the Vista desktop to give options to display combinations on either monitor (external or laptop)
But if I boot to Linux the loading progress bar shows on the external , up to when the mouse cursor would be displayed, but then all display moves to the laptop monitor.
Is there any way that I can control the Linux display to which monitor ?

This very much depends on which graphic card you have
You can run lspci (note the l is a lower case L) in a terminal to find out and also post it here
My Radeon card gets crazy if I try to open "Display" (in Gloria) but there should be an option for dual monitors there
There is also xrandr an excellent tool but it is run in the terminal and takes some reading to understand
If you have ATI there is the ATI Catalyst Control Center (if you have the ATI driver installed)
For nvidia you have "nvidia settings" (Must be run as root for settings to be persistent)

In 'Display' I find configuration to set up ' twin views ' . It recognized my external monitor and I set this dfiaogue and saved to xorg.conf , but I do not know how to run nvidia settings in Root , the dialogue window shows no Root option . Here is my xorg.cnf and it shows no change since it was first read : -

# xorg.conf (X.Org 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 xorg.conf manual page.

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

# here are ignored.

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

Solved. I found that the launch file for nvidia is ' nvidia-settings ' in Root CLI . That enabled me to configure the two monitors. Just had a little experiment to get the two screens oriented in relation.
Great job on Mint Gloria.

Yupp
I can't understand why nvidia does not make it an application that asks for a root password - as it is it creates problems
