chromium scales huge when run from an lxc container

[Nick Moffitt]

I followed stgraber's excellent tutorials in https://www.stgraber.org/2014/02/09/lxc-1-0-gui-in-containers/ and got a container that has X11 and DRI and pulse access. It works really well!

But the odd thing is that chromium run from inside the container turns out enormous on my 1920x1080 display in a way that chromia run outside the container do not. I checked xrandr and xdpyinfo from both sides and nothing changed.

I asked stgraber about this, and he doesn't see it with the proprietary chrome builds. http://ubuntuforums.org/showthread.php?t=2225788&s=dd2819f676875c608dbac135d66ce9c9&p=13032314 shows someone seeing it within KDE. So it seems as though Unity/gnome set some sort of aura DPI environment up that I'm not getting yet in my LXC container.

I'd be happy with a workaround at the moment, but really I just hope I don't need to install dbus inside my lxc :)

Is this still an issue now that Chromium 71.0 is the currently supported version?
