Ubuntu 17.10 High DPI support
Contributor IHi,
The Rapidminer studio I installed for my linux system has small icons and texts due to the DPI of my screen. I found this link https://docs.rapidminer.com/studio/installation/hidpi.html regarding the fix but I do not know where to put the java option "-Dsun.java2d.uiScale=2" I tried leaving it here in the shell script
JVM_OPTIONS=$("$JAVA" "-Djava.awt.headless=true -Dsun.java2d.uiScale=8" -cp "${rmClasspath}" com.rapidminer.launcher.JVMOptionBuilder "$@) but it didn't change any scaling after running the script.
Below is the shell script to run the program
#!/bin/bash

If anyone knows a solution without having to change my own screen resolution, I would very much appreciate it.
Thanks!

I figured it out. For anyone wondering, the parameter "..uiScale = 2" does not work in openjdk8. It's fixed in openjdk9
Thank you @zl1775. I know this is NOT an ideal way to change something as simple as the screen resolution. I have sent this on to the dev team and hopefully an easier method will appear in a future release.
