URL: https://github.com/apache/netbeans/pull/3113


   This commit modifies the NetBeans IDE launcher scripts to automatically 
handle two display-related conditions on Linux:
   1) Automatically enable the -Dawt.useSystemAAFontSettings system parameter 
if necessary to enable anti-aliased text. Veteran NetBeans users have known 
about this setting for a long time, but after a lot of research, I believe I 
have found the specific condition in which it is necessary, namely on the K 
desktop environment.
   2) Automatically detect cases where the user has enabled 2x HiDPI scaling, 
via the Xft.dpi Xresource, and set the GDK_SCALE environment variable 
accordingly so that OpenJDK will handle this accordingly. This seems to work on 
both KDE and Gnome. HiDPI scaling works best on FlatLAF, but seemed to work 
tolerably on the default GTK LAF as well. (Perhaps in the future we should 
consider making FlatLAF the default LAF on Linux.)
   
   See the in-code comments for more details. (There are two copies of the new 
code: one in the IDE launcher script, and one in the launcher script for 
NetBeans Platform applications.)
   
   It would be great if multiple Linux people could test NetBeans with the 
modified launcher scripts, on both Gnome and KDE (and any other desktop 
environments that exist out there).
