Fix QT Apps scaling issue on hidpi screens on Ubuntu

Posted on January 21, 2019 by SoCRaT

On my 5k screen, all QT apps look very tiny, such as keepassxc and Virtualbox.

The best solution I found was adding the following to your .profile to autoscale at a ratio of 2 (you can change it to your preference):

export QT_SCALE_FACTOR=2

Set to 2 because my display settings are set to 2

Log out and back in, and there you go!

Tested on Ubuntu 18.10

Enjoy!

    Thanks for sharing. The trick did fix some displaying issues, but not the scaling though! Are you setting the two screens to the same resolution?

      Actually my screens are not at the same resolution, one is 4k and the other is 5k. In general, this fixes only for QT based apps.

      Kind Regards,
