    Cant set screen resolution to 1440x900

    Hello guys and ladies, my first post at kubuntuformus

    All I want is to set kde to 1440x900, but it always displays at 1280x768

    This is my setup
    Monitor: HP w17e (best resolution is 1440x900@60)
    Graphics Adapter: 01:05.1 Display controller: ATI Technologies Inc Unknown device 5874 (data from lspci)


    Procedures I've tried
    Procedure: Changing Settings from System Settings or kcontrol
    Result: The module Monitor & Display is not loaded (see attachment)

    Procedure: Changing or removing xorg.conf and restarting X
    Result: Nothing special happens, it continues working ok, but not at desired resolution

    Procedure: Running dpkg-reconfigure xserver-xorg and restarting X
    Result: Nothing special happens, it continues working ok, but not at desired resolution

    Procedure: Running dpkg-reconfigure -phigh xserver-xorg and restarting X
    Result: Nothing special happens, it continues working ok, but not at desired resolution


    Procedure: Removing ~/.kde/share/config/displayconfigrc and restarting X
    Result: Login is not possible. Must restore displayconfigrc


    This is the output of running displayconfig

    Code:
    Traceback (most recent call last):
     File "/usr/bin/displayconfig", line 1755, in <module>
      displayapp = DisplayApp()
     File "/usr/bin/displayconfig", line 441, in __init__
      self.xsetup = XSetup(self.xconfigpath)

     File "/var/lib/python-support/python2.5/xf86misc.py", line 77, in getSize
      return self.sizes[self.currentsizeid]
    IndexError: list index out of range


    This is the output of running xrandr

    Code:

        v: height 768 start 769 end 772 total 795      clock  60.0Hz


    And this is xorg.conf


    Code:
    Section "InputDevice"
        Identifier   "Generic Keyboard"
        Driver     "kbd"
        Option     "XkbRules"   "xorg"
        Option     "XkbModel"   "pc105"
        Option     "XkbLayout"   "latam"
    EndSection
    
    Section "InputDevice"
        Identifier   "Configured Mouse"
        Driver     "mouse"
        Option     "CorePointer"
    EndSection
    
    Section "Device"
        Identifier   "Configured Video Device"
    EndSection
    
    Section "Monitor"
        Identifier   "Configured Monitor"
    EndSection
    
    Section "Screen"
        Identifier   "Default Screen"
        Monitor     "Configured Monitor"
        Device     "Configured Video Device"
    EndSection
    
    Section "ServerLayout"
        Identifier   "Default Layout"
        Screen     "Default Screen"
    EndSection

    I dont know what else should I try. I know you smart guys must have the solution, thanks in advance, and I hope I can contribute to this community

    Do you have errors in the xorg log ?
    Konsole:
    Code:
    grep "(EE)" /var/log/Xorg.0.log

    Something to try

    Backup xorg.conf and then change

    Code:
    Section "Screen"
        Identifier   "Default Screen"
        Monitor     "Configured Monitor"
        Device     "Configured Video Device"
    EndSection
    to
    Code:
    Section "Screen"
    	Identifier	"Default Screen"
    	Device		"ATI Technologies Inc unknown device"
    	Monitor		"HP w17e"
    	DefaultDepth	24
    	SubSection "Display"
    		Modes		"1440x900"
    	EndSubSection
    EndSection
    Is this helping ? Any errors ?

      Thanks Rog for the reply.
      I've just tried your suggestion, but nothing happened. After restarting X, I have the old and ugly resolution.
      Modifying /etc/X11/xorg.conf seems to have no effect in X settings

      this is the output of

      grep "(EE)" /var/log/Xorg.0.log

      Code:
          (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
      (EE) RADEON(0): No connected devices found!
      (EE) RADEON(0): Using VGA default

      Humm... RADEON?? Do I have a Radeon??. Well, with or without radeon, all I want is to change screen resolution to 1440x900
      thanks

        Re: Cant set screen resolution to 1440x900

        Is this EDID bug ? > EDID fail
        Current xorg in Hardy usually autodetects your monitor, it's resolution, dpi, etc. and everything just magically works. This happens because modern monitors can be queried for 'EDID' data, that returns all the necessary info to configure things properly.

        However, there are cases where the monitor fails to report EDID. These exhibit themselves as a variety of symptoms, often including incorrect resolution selection...

        To determine if you have this issue, simply run `sudo ddcprobe` or `sudo get-edid | parse-edid`, and you will see 'EDID fail' in the output.
        What tells ?:
        Code:
        sudo get-edid | parse-edid

        Or maybe this helps > Topic: How to fix monitor resolution problem

          Thanks again Rog

          To run sudo get-edid | parse-edid I had to sudo apt-get install read-edid

          and this is the output of

          sudo get-edid | parse-edid

          Code:
          get-edid: get-edid version 1.4.1

          The EDID data should not be trusted as the VBE call failed
          Error: output block unchanged
          parse-edid: parse-edid version 1.4.1
          parse-edid: IO error reading EDID
          Nice, more info about my video device "ATI RADEON XPRESS 200 Series".
          But IO error reading EDID does not makes me happy

          I've read the bug in launchpad, and the monitor is plugged with the cable that came in the monitor box. I will follow some instructions that are there, and I will post again.

          Thanks
