resume on wrong monitor

Can anyone tell me why my iMac (mid-2010, 21.5, 500GB disk, 4GB RAM, radeon 4670 video), running Arch (xfce), always starts on the main monitor (with external monitor connected, but not switched on) but then sleeps, and resumes only on my external monitor (seen after I switch it on). The same happens with ubuntu and manjaro (in KDE), but not OSX.
I reckon the video card connectors are cross-connected and the radeon kernel driver chooses the wrong one on resume. But why choose the right one at boot?

Re: resume on wrong monitor

I'm exacty in the same situation, though I've installed Debian Testing (kernel 4.7) in my brother's (mid 2010) iMac to provide him with a stable and maintenance free system (as it's about to become the new stable). Yet I may consider Arch as well if you or the new Arch packages and kernel have solved the issue?

Please don't necrobump; especially for an issue with another distro: https://wiki.archlinux.org/index.php/Co … pport_ONLY
