I'm running elementary OS Freya (based on Ubuntu 14.04) on a MacBook Pro 13.3" 2013 Retina and I'm having weird DPI problems:
- Some applications (eg Google Chrome) have no awareness of DPI settings and so they just display natively. All other applications display scaled up (text is readable) while Google Chrome text displays at 12px physical pixels, meaning text is extremely small.
- I have a 23" 1080p monitor connected to DisplayPort and the DPI settings seem to stay the same across monitors. This means that my 1080p display looks like it's at 640x480, everything is HUGE and on the internal MacBook screen (2560x1600), things look normal.
xrandrdoesn't seem to remember my monitor settings, as I'll set my main screen to off and when logging in, it always turns on, screwing up the DPI on my external monitor.
I believe that I'm running Wayland on here, though I can't find any processes with
ps aux | grep wayland:
$ aptitude search '~i wayland' i A libwayland-client0 - wayland compositor infrastructure - client lib i A libwayland-cursor0 - wayland compositor infrastructure - cursor lib i A libwayland-egl1-mesa - implementation of the Wayland EGL platform -- i A libwayland-server0 - wayland compositor infrastructure - server lib
I don't have any System Settings which control the DPI in the GUI.
I've tried using
xrandr --dpi 75 and nothing changes. Restarting applications also doesn't seem to have an effect.
I think that it's running Wayland inside of X server. Is there any configuration file I could use to change the DPI globally or per-monitor?
