# Ubuntu – Ubuntu GNOME and high resolution screen: icons in QT apps are too small. How to solve

display-resolutiongnomeiconsqt

my brother got a new laptop, a Thinkpad X1 Carbon 4th generation. It features a screen with a rather large resolution of 2560×1440 px.

Out of the box, GNOME scales well the size of the text and the icons, as you may see from this screenshot of LibreOffice:

Unfortunately QT apps seem not to behave the same, as seen in this screenshot of TexMaker:

As you may see the icons are too small and rather difficult to reach.

How can he uniform the look&feel of the QT apps to the one of the GTK apps?
Is there some compatibility package that he has to install? Or some configuration to make?

• The answer depends on which version of qt you are using, qt4 or qt5. The following will tell you which version of qt you are using.
ldd $(which$NAME) | grep qt -i
For qt5 you can use an environment variable QT_SCALE_FACTOR, for qt4 you can change font sizes using qtconfig-qt4, but it would appear that icon sizes don't scale. You might, however, be able to use a different icon set, or if you are very energetic scale up another icon set yourself.
