LBK Post 028 Xrandr: Solve Screen Resolution Issues via Command Line in Ubuntu / Debian



Xrandr (X Rezise and Rotare) is a command line utility available in your Linux system for reseting and resizing your screen resolution. So, if there is any issues with your display, no problem you can fix it from a Terminal.

First You have to find the possible resolutions with xrandr -q

    $ xrandr -q
    Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192

    LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm
       1280x800       60.0*+
       1024x768       60.0
       800x600        60.3     56.2
       640x480        59.9
    VGA1 disconnected (normal left inverted right x axis y axis)
    HDMI1 disconnected (normal left inverted right x axis y axis)
    DP1 disconnected (normal left inverted right x axis y axis)
    DP2 disconnected (normal left inverted right x axis y axis)

Now you can set your resolution with command

    $ xrandr -s 1024×768

More Details

    $ man xrandr

Linux 3.1 Released with NFC Support

The Linux 3.1 kernel has been released several weeks late, providing enhancements to performance, virtualization, and power management. Linux 3.1 also includes support for near field communication (NFC), the OpenRISC open source CPU, Nintendo's Wii controller, and 3D acceleration with Nvidia GEForce graphics processor units (GPUs).

The new kernel arrives more than three months after Linux 3.0, after having been delayed several weeks by a late-August malware attack on kernel.org. The release offers a grab-bag of goodies from new performance and virtualization enhancements to support for new devices including NFC-enabled smartphones.
