Ubuntu – Adapt Ubuntu to a high-DPI resolution screen


How can I adapt Ubuntu to a high resolution display?

I have a display with 3200x1600px on only 11'' and everything looks really tiny.

  • There are some steps to take:

    1. System wide Menu and titlebar scaling

    Starting with Ubuntu 14.04 we have an option that helps a bit:

    Scaling Support

    open the System Settings (here in english:)

    LANG=c unity-control-center

    Go to "Displays" and set the "Scale for menu and title bars":

    system settings scale system wide

    Since Ubuntu 17.10 the scaling can be set in

    LANG=c gnome-control-center

    Go to Settings > Devices > Displays there

    2. Universal Access

    Go to "Universal Access" (unity-control-center universal-access) and select "Large Text".
    Note: not all applications handle this correctly, some will not reserve the extra space, so some UI elements are not accessible with this option!

    3.increase unity dock size

    In unity-control-center->Appearance->Look at the botom, you can adjust the size

    4. adapt Firefox

    see: Adjust Firefox and Thunderbird to a High DPI touchscreen display (retina)

    (or use Chrome, which works fine since Version 41.0.2272.76 Ubuntu 14.10, though Chrome will need to be restarted to take effect)

    5. increase font in Pidgin

    There is a plugin you can install

    sudo apt-get install pidgin-extprefs

    Then you can increase the font in Plugins->Extended Prefs

    6. create starter for applications that still don't scale

    Some applications still don't obey the global scaling (mainly java) for those few applications you can create a starter to only Fix scaling of java-based applications for a high DPI screen

    in older Ubuntu versions, with unity-tweak-util in the section "Fonts" you can set the "Text Scaling Factor" to 2.0. This will scale the fonts in most applications to double size.
