It’s been a while since my last post. But it is never late to be back.
Recently I moved from a MacBook Pro 15″ to a Dell XPS 9650 with Ubuntu 17.04. Ignoring all the trouble I had to install dual boot in the new system that I solved after I found this thread.
My new Dell XPS has a 4K screen. There is something funny with those Retina displays. Many applications scale very poorly on Windows and Linux. QtCreator is one of them. No dpi scaling are enabled by default. To enable is necessary to set an environment variable called
QT_AUTO_SCREEN_SCALE_FACTOR as explained here.
Another issue is that dual monitor with different dpi are not supported, only one dpi scaling is available at any time. This is not the end of the world because I can just turn off my laptop screen. I don’t look at it anyway when I have a second monitor.
I guess that what happen when you are a the cutting edge of technology. It is not a surprise that you get some scratches.
