Created attachment 503490 [details] Xorg log I have a dual-head display that worked fine in F14, but after upgrading, the heads are swapped, so X thinks the leftmost display is actually on the right, making the mouse-wrapping between screens weird.
You can change the display arrangement using the relevant control center panel in gnome control center. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
That's right workaround, but not a fix. Passing to developers.

Actually do use /etc/X11/xorg.conf or did you rely on Gnome to do the configuration? If the former, could we get it as well, please? Thank you
xorg.conf is irrelevant. only contains this.. Section "ServerFlags" Option "DontZap" "no" EndSection
Radeon driver bug, although I suspect the answer is "yeah, output enumeration changed, sorry about that".
is it likely to be changed back ? or is "move the monitors on your desk around" the solution ? (I don't mind doing the latter, as long as I'm not doing it every release)
I don't think output enumeration changed but it might have. Could you get a dmesg when booting with drm.debug=4 both with f14 & f15 ? Anyway it's very likely to be just an enumeration change somewhere either in kernel or ddx.
This is my main workstation, so reinstalling f14 would be a pain right now. I have a dmesg from the old install, but it didn't have the drm.debug=4 switch, so not really helpful I guess. I'll get the f15 dmesg next reboot.
Created attachment 512289 [details] dmesg with drm.debug=4
I was thinking something like boot f14 livecd
Even log from f14 with drm.debug could be helpfull
Without
nnggh. the f14 livecd doesn't complete booting. I'll try fighting it for a while to see if I can at least get it as far as booting X. (right now it dies trying to find its root fs)
I think this isn't an X issue after all. I used to run gnome, and with f15, I switched to xfce. I just stumbled across a setting that starts all the gnome-session stuff when xfce logs in. When I enable that, something runs just after I log in, which switches the heads into the positions I expect them to be in. So feel free to close this out..
