Change Resolution of Unknown Monitor in Ubuntu 11.10

January 30, 2012

Ubuntu LogoI have the HP v185e Monitor and it was unrecognizable by my Ubuntu 11.10. The “Display” setting shows “Unknown Monitor”, and the maximum resolution I could get is 1024 x 768, the optimal resolution is 1368 x 768. I found that the “Unknown Monitor” could be set with XRandr from the posting in the Ubuntu Forum.

I did that right and the resolution is 1368 x 768, but after restarting, the resolution options were reverted back to 1024 x 768. From the Ask Ubuntu, I found that Ubuntu 11.10 have different way to permanenting the XRandr customization than it’s predecessors.

XRandr 001

Here’s the summary (I’m using the example of adding 1440 x 900 resolution):

  1. Open Terminal and type
  2. $ xrandr
  3. The XRandr will show the maximum resolution allowed like this:
  4. Screen 0: minimum 320 x 200, current 1368 x 768, maximum 8192 x 8192
    VGA1 connected 1368x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
       1368x768_60.00   59.9*+
       1024x768       60.0  
       1024x768_60.00   59.9  
       800x600        60.3     56.2  
       848x480        60.0  
       640x480        59.9  
       1280x800_60.00   59.8  
    HDMI1 disconnected (normal left inverted right x axis y axis)
    DP1 disconnected (normal left inverted right x axis y axis)
    HDMI2 disconnected (normal left inverted right x axis y axis)
    DP2 disconnected (normal left inverted right x axis y axis)
    
  5. Type “cvt [x resolution] [y resolution]” in the terminal, for my case is like this:
  6. $ cvt 1440 900
  7. The Terminal will show the output:
  8. # 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz
    Modeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync
    
  9. For the next step, type:
  10. $ xrandr --newmode [Modeline]

    in my case is

    $ xrandr --newmode "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync

    Copy the “Modeline” configuration from the previous output

  11. To add the new resolution to the “Display” option type:
  12. $ xrandr --addmode VGA1 1440x900_60.00

    Now the new resolution is ready in the “Display” option
    XRandr 002

  13. To apply the new resolution, type:
  14. $xrandr --output VGA1 --mode 1440x900_60.00

    And now the screen will be in the new resolution

  15. In order to make it permanent, add the resolution to /etc/X11/xorg.conf
  16. $ sudo gedit /etc/X11/xorg.conf
  17. The xorg.conf will show the output like this:
  18. Section "Monitor"
        Identifier    "Monitor0"
        Modeline "1280x800_60.00"   83.50  1280 1352 1480 1680  800 803 809 831 -hsync +vsync
        Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
        Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
    EndSection
    
    Section "Screen"
        Identifier     "Screen0"
        Device         "Card0"
        Monitor        "Monitor0"
        SubSection "Display"
            Modes      "1280x800_60.00" "1368x768_60.00" "1024x768_60.00"
        EndSubSection
    EndSection
    
    Section "Device"
        Identifier    "Card0"
        Driver        ""
    EndSection
    
  19. Add the new Modeline and resolution, for the “Driver” in the “Section Device” I just simply type “Intel” (because I’m using intel standard graphic card), if you are using Nvidia just simply type “nvidia”. The output is like:
  20. Section "Monitor"
        Identifier    "Monitor0"
        Modeline "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync
        Modeline "1280x800_60.00"   83.50  1280 1352 1480 1680  800 803 809 831 -hsync +vsync
        Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
        Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
    EndSection
    
    Section "Screen"
        Identifier     "Screen0"
        Device         "Card0"
        Monitor        "Monitor0"
        SubSection "Display"
            Modes      "1440x900_60.00" "1280x800_60.00" "1368x768_60.00" "1024x768_60.00"
        EndSubSection
    EndSection
    
    Section "Device"
        Identifier    "Card0"
        Driver        "intel"
    EndSection
    
  21. Restart and see the resolution setting is now permanent

Hope it worked

KDE 4, Ready or Not Ready?

July 19, 2008

KDE 4 LogoBefore we go to the topic, I just want to say that this post doesn’t suggest you to be ready to use KDE 4, but in contrary I just want to review and give my opinion about the brand new KDE 4.

If you are the Linux user, before you log in you can choose the type of sessions (except if you are Ubuntu users), there are Gnome, KDE and XFCE. Every users has their own preferences, I don’t know about Indonesia, but as long as I know that American users prefer more to Gnome and European users prefer more to KDE since Gnome is from US and KDE is from Germany.

I used to be preferred more to Gnome because of it’s more customizable, but since KDE 4 launched and released officially, it has attracted me with the widgets and it’s Vista-like layout. So I could show it to my friends and prove that Linux is cool!
View of My KDE 4 Desktop

I’m running Kubuntu 8.04 (not an official version but a community development version with KDE 4 inside) at my laptop and OpenSuse 11 at my desktop. Then I found several problems in using KDE 4 :

Between OpenSuse, Fedora and Ubuntu

July 14, 2008

They are the big three distros in the Linux World

Open Suse LogoOpenSuse
OpenSuse is a powerful distro, originally it came from Germany, but later the company bought by Novell which is an US company. It’s a very stable but conservative distro, they would not include the program if that’s not stable yet, For Example they still put RealPlayertm 10 rather than RealPlayertm 11 (and it almost one year after the 11th released).

  • Strength
  • It’s very strong and stable distro, rarely crashed (unless you try to install something which not compatible). The YAST control panel is an easy and user friendly configuration tool
  • Weakness
  • Yet it’s stable but it’s out of date (or yet it’s out of date but it’s stable, i’m confused), you can’t enjoy the latest version of the program as soon as another distro, and it’s rather difficult to hack this distro, because the alternative package is difficult to find.

Fedora LogoFedora
A free operating system from the famous distro : RedHat. Fedora offers You an easy to customize system. A lot of RPM available everywhere, and it’s easy to install (like .exe programs).
