I know that, I meant more 'how to verify the effects of this setting' :)

Maybe I should have been more clear.

Thank you for the tip !

Since I have the same setup as the reporter I have applied the patch provided 
in this bugreport, and then HighDPI works on Linux.
The buttons and images have a reasonable size, font looks normal...

So, from my point of view, that patch can be applied ASAP :)
