xrandr, xorg.conf


I have a fancy 1440x900 monitor. My xorg.conf looks like this:
Code:
Section "Screen"
    Identifier     "Screen 1"
    Device         "NVIDIA GeForce 6600 GT"
    Monitor        "ACER X193W LCD MONITOR"
    DefaultDepth    24
    SubSection     "Display"
        Viewport    0 0
        Depth       8
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Viewport    0 0
        Depth       16
        Modes      "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Viewport    0 0
        Depth       24
        Modes      "1440x900" "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection
I put that 1440x900 in myself. Whenever I start X I am in 1440x1024 resolution. Why? I have to run xrandr every time to change it to 1440x900. I don't understand.

If it helps here is my lspci:

I have an Nvidia GeForce 6600GT. I installed and ran their linux driver shellscript. I ran xorg.conf and entered all the info. When it asked for a card type I put 350 which was NVidia GeForce, there was only one GeForce choice, I guess that was right, I don't know. Then later on I added 1440x900 to xorg.conf manually.

Use modelines in the monitor section


and simplify the display subsection

SubSection "Display"
Depth 24
Virtual 1400 900
Modes "1400x900@95" "..."...
EndSubSection


If it is the new X then consider

#Section "ServerLayout"
# "AutoAddDevices" "off"
#EndSection

Do you use the "nv" or the "nvidia" driver?

That is the size of my qosmio laptop's screen.

Here is my monitor section of xorg.conf:
Code:
Section "Monitor"

  # created by KGamma
  # created by KGamma
    Identifier     "Monitor[0]"
    VendorName     "--> LCD"
    ModelName      "1440X900@60HZ"
    UseModes       "Modes[0]"
    DisplaySize     365    230
    HorizSync       30.0 - 38.0
    VertRefresh     30.0 - 61.0
    Gamma           1.05
    Option         "CalcAlgorithm" "XServerPool"
    Option         "DPMS"
    Option         "PreferredMode" "1440x900"
EndSection
Here is my "Screen" section:
Code:
Section "Screen"

# Removed Option "metamodes" "DFP: nvidia-auto-select +0+0"
# Removed Option "metamodes" "DFP: 1440x900 @1440x1024 +0+0"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "0"
    Option         "metamodes" "1440x900 +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection
Here is my layout section:
Code:
Section "ServerLayout"
    Identifier     "Layout[all]"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard[0]" "CoreKeyboard"
    InputDevice    "Mouse[1]" "CorePointer"
    InputDevice    "Mouse[3]" "SendCoreEvents"
    Option         "Clone" "off"
    Option         "Xinerama" "off"
EndSection
Notice how the Screen identifier matches what is in the layout section. You can add an additional screen section with a different identifier and if it doesn't work, change the layout section's Screen entry to what it was before. Having an lcd monitor, I don't have entries for other resolutions. They still work (usking krandrtray for example) automatically and don't need to be listed. I always use the default resolution of an LCD monitor. The newer versions of Xorg can use built in defaults if sections aren't included in the xorg.conf file.
