I still feel the problem is monitor 2 is in portrait mode and monitor 1 is landscape mode, using the printing terminology.

That's how I tested (rotate left), on either side of primary (landscape, not rotated).

...debug version of nouveau...

Nouveau is a generic term that applies to multiple "layers": 1-Kernel module: (not a separate package, though it can be blacklisted) 2-X foundational: xf86-video-nouveau 3-Other X: Mesa, drm, vdpau, more(?) #2 is old technology. Did your testing of "more variants" include the newer technology, aka modesetting, which is not a separate package? Did "more variants" include compositing disabled? -- You are receiving this mail because: You are on the CC list for the bug.

With limited knowledge of the interaction of each component I feel tackling the current software in opensuse 15.0 is my best approach.

Feel free to attack problems in any manner you choose. Note that "current" has included the modesetting driver since 42.1 was in beta testing nearly three years ago, as it has been and is automatically used by default when supported by the hardware and optional software such as xf86-video-nouveau is not installed. -- You are receiving this mail because: You are on the CC list for the bug.

I tried to attach the coredump but it was rejected for being too large. The backtrace is not much help

Indeed. Coredumps are somehow not relocated properly. Is there anything useful in the journal? Do you get the drkonqi crash report window? -- You are receiving this mail because: You are on the CC list for the bug.

When it segfaults, I lose the screen completely and then I'm back to login screen

Ok, so it's not just the kscreen segfault. That would just cause the configuration to not get applied.

Nothing useful in dmesg, no journal just a core dump, and no crash window.

Can you provide the sudo journalctl output at the time of the crash? -- You are receiving this mail because: You are on the CC list for the bug.

Created attachment 795382 [details] journctl output

There is some extra debug I have added to xrandr library You will see it in the output I added it in the hope of entering a function and not leaving it, to find the problem. toKScreenScreen //is entering function toKScreenScreen toKScreenScreenEOF // is existing function toKScreenScreen But again there was nothing useful, And it did not change the bug.

I don't see any crash in there, is anything useful in ~/.local/share/sddm./xorg-session.log or /var/log/Xorg.0.log(.old)? -- You are receiving this mail because: You are on the CC list for the bug.
