Resize Ghidra for High DPI screens

If you run Ghidra on a high DPI screen, you will probably find the GUI to be scaled down so small to be almost of no use.

There is a setting that you can adjust to scale the Ghidra GUI:

in $GHIDRA_ROOT/support is a file named launch.properties. In this launch.properties file is the following configuration key:

VMARGS_LINUX=-Dsun.java2d.uiScale=1

Change this line to:

VMARGS_LINUX=-Dsun.java2d.uiScale=2

Then launch ghidra and you should be good to go!

How do I make the change on a Ubuntu system with a snap ghidra? The /snap/ filesystem is read-only.

Not familiar with Snap, but I think it should be possible to run $GHIDRA_ROOT/support/launch.sh bg jdk Ghidra "" "-Dsun.java2d.uiScale=2" ghidra.GhidraRun directly. This works for me on Arch Linux.

The command is taken from $GHIDRA_ROOT/ghidraRun which is just a wrapper for launch.sh. launch.sh accepts extra vmargs via CLI but ghidraRun doesn't expose this to the user.
