dual monitors...it already detects my 2nd monitor


Hi,

I know there are currently other posts out there now about dual monitors, but I have a kind of different situation. Slack is already detecting both of my monitors, or so it appears, because it displays the exact same thing on both of them. What do I need to do to my X-Config file for it to display it all across a single desktop?

Thanks in advance!
Shaun

Ok,

That link helped me a lot, however, I still can't get the 2 monitors to work right...

Here's my XF86Config file (leaving out the top junk):

Section "Module"

# This loads the DBE extension module.

Load "dbe" # Double buffer extension

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
SubSection "extmod"
Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection

# This loads the font modules
Load "type1"
Load "freetype"
Load "speedo"

# This loads the GLX module
Load "glx"

EndSection

# **********************************************************************
# Files section. This allows default font and rgb paths to be set
# **********************************************************************

# The location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.

RgbPath "/usr/X11R6/lib/X11/rgb"

# Multiple FontPath entries are allowed (which are concatenated together),
# as well as specifying multiple comma-separated entries in one FontPath
# command (or a combination of both methods)
#
# If you don't have a floating point coprocessor and emacs, Mosaic or other
# programs take long to start up, try moving the Type1 and Speedo directory
# to the end of this list (or comment them out).

# Uncomment this to cause a core dump at the spot where a signal is

# provide a better stack trace in the core dump to aid in debugging

# Option "NoTrapSignals"

# Uncomment this to disable the <Crtl><Alt><Fn> VT switch sequence
# (where n is 1 through 12). This allows clients to receive these key
# events.

# Option "DontVTSwitch"

# Uncomment this to disable the <Crtl><Alt><BS> server abort sequence
# This allows clients to receive this key event.

# Option "DontZap"

# Uncomment this to disable the <Crtl><Alt><KP_+>/<KP_-> mode switching
# sequences. This allows clients to receive these key events.

# Option "DontZoom"

# Uncomment this to disable tuning with the xvidtune client. With
# it the client can still run and fetch card and monitor attributes,
# but it will not be allowed to change them. If it tries it will
# receive a protocol error.

# Option "DisableVidModeExtension"

# Uncomment this to enable the use of a non-local xvidtune client.

# Option "AllowNonLocalXvidtune"

# Uncomment this to disable dynamically modifying the input device
# (mouse and keyboard) settings.

# Option "DisableModInDev"

# Uncomment this to enable the use of a non-local client to
# change the keyboard or mouse settings (currently only xset).

# Option "AllowNonLocalModInDev"

# Set the basic blanking screen saver timeout.

# Option "blank time" "10" # 10 minutes

# Set the DPMS timeouts. These are set here because they are global
# rather than screen-specific. These settings alone don't enable DPMS.
# It is enabled per-screen (or per-monitor), and even then only when
# the driver supports it.

# Option "standby time" "20"
# Option "suspend time" "30"
# Option "off time" "60"

# On some platform the server needs to estimate the sizes of PCI
# memory and pio ranges. This is done by assuming that PCI ranges
# don't overlap. Some broken BIOSes tend to set ranges of inactive
# devices wrong. Here one can adjust how aggressive the assumptions
# should be. Default is 0.

# Option "EstimateSizesAggresively" "0"

A hunch that I have is that it might be the fact that I don't actually have a manufacturer or model of video card selected, because my specific card (Nvidia Geforce FX 5200) is not there in the list in the X GUI Config. The reason why I don't have any one at all selected is because it changes the file which messes up the Nvidia drivers that I have set up from the Nvidia site. It just seems like it's about there, but just one little tweak short.

Thanks for the help,

Shaun

This is what I have in my file.

Code:
Section "ServerLayout"
        Identifier     "XFree86 Configured"
#       Identifier      "DualHead"
        Screen      0  "Screen0" 0 0
        Screen      1  "Screen1" LeftOf "Screen0"
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
#       Option         "Xinerama" "on"
EndSection

Section "ServerFlags"
#        Option "Xinerama" "true"
EndSection
I uncomment both options if I want Xinerama instead of a clone.

sorry if my reply is late...

but if you have a fx5200 just use the nvidia driver at www.nvidia.com, it twinview wich is a lot easier to setup, just install the driver and look at the documentation in /usr/doc/NVIDIA_GLX-1.0/README

Oh, ok, hmmm...I have the driver and I know I installed it properly, but I'll have to look into that readme for more info.

Thanks,
