[jira] [Comment Edited] (NETBEANS-2360) HiDPI scaling not applied automatically on Linux

I believe this sets a gnome property known as "Xft/DPI". Java does not seem to react to this property at the GraphicsConfiguration level, however; that should probably be reported as an OpenJDK bug/feature request. Meanwhile, GDK_SCALE works fine for setting the scaling level at the GraphicsConfiguration transform level. Note that the default LAF on Linux (GTK+) gets into trouble when Xft/DPI is set, because some UI elements end up being scaled and others don't. What does work is to set GDK_SCALE and use FlatLAF. In that case, all the UI elements appear properly scaled, regardless of whether Xft/DPI is set in addition. Perhaps FlatLAF should be made the default LAF on Linux, and the NetBeans startup script should set GDK_SCALE automatically based on the value of Xft/DPI. was (Author: ebakke): As of the latest Ubuntu release, Ubuntu 20.04, the "Displays" control panel has a "Scale" factor option.
