How to change display scaling settings in Lubuntu, so that the font, the icons and the buttons are bigger, similar to Mac OS X, in size?

    Scaling is a known issue with LXQt - https://github.com/lxqt/lxqt-config/issues/401 @Andy's answer would require adding a fair amount of KDE (inc. KF5/KDE Frameworks) to your system, where LXQt (L=light) aims to be a light, and thus doesn't include it. – guiverc Dec 09 '20 at 03:45

In Lubuntu 21.10, I had to go through the following steps:

  1. Open LXQt Configuration Center -> Session Settings -> Environment Variables (Advanced) or run lxqt-config-session
  2. Add QT_SCALE_FACTOR with value 2
  3. Add GDK_DPI_SCALE with value 2
  4. Add XCURSOR_SIZE with value 64

Screenshot of LXQt Session Settings showing the three additional environment variables

  1. Open LXQt Configuration Center -> Appearance -> Font and set Resolution (DPI) to 192

  • I can confirm that "this is the way". In my case, I have a stretch virtual display (for remote operation via smartphone) and played with scale values: decimals are allowed, GDK and QT doesn't have to be equals, for what is worth. – leoperbo Apr 19 '22 at 03:00
  • Does this work for a laptop which has a HiDPI screen and then plugging in an external monitor that is not HiDPI? Meaning, is this scaling global, or per-display? – ahogen Feb 10 '23 at 15:26
  • your screen shots are drop dead... – user2183336 Nov 30 '23 at 20:12
  • The proposed solution is very effective. Almost all elements are correctly displayed on the HiDPI screen. However, some elements such as the Close/Maximize/Minimize buttons of the windows remain displayed incorrectly. – M.Moro Apr 19 '24 at 03:42

LXQt now has a global screen scaling option on the 'session settings' as directed above. Set it to 2, or in my case I am on a different monitor
