Created attachment 129637 [details] crash report second monitor ok until login, then both monitors go black
Does syslog (or wherever ksmserver puts its log output) have any messages containing the word "Assertion"? The crash seems to be an assertion failure in libpulsecommon. Can you install the debug symbols for libpulse and libpulse-glib-mainloop? Without the debug symbols the backtrace doesn't show the exact location of the crash.
Yast control centre, miscellaneous, System log shows no file found. cannot find ksmserver log libpulse-mainloop-glib0 & libpulse-mainloop-glib0-debuginfo found in repositories and now installed. updated to latest tumbleweed kernel 4.9.9.12 today. pulse audio crash cannot be repeated and all monitors are now working correctly
Ok, since this can't be reproduced any more, I'll close the bug.
