Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git master, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: > #4 0x0000713c359e8516 in ??? () at /usr/lib/qt6/plugins/kf6/kscreen/KSC_KWayland.so Could you please install debug symbols for KWin and KScreen and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again! I ran DEBUGINFOD_URLS="https://debuginfod.archlinux.org" coredumpctl gdb 451197 and then typed "bt" when it hits the prompt, this is all it gives me: #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=11, no_tid=no_tid@entry=0) at pthread_kill.c:44 #1 0x00007620a3eab393 in __pthread_kill_internal (signo=11, threadid=<optimized out>) at pthread_kill.c:78 #2 0x00007620a3e5a6c8 in __GI_raise (sig=11) at ../sysdeps/posix/raise.c:26 #3 0x00007620a63f644f in KCrash::defaultCrashHandler (sig=11) at /usr/src/debug/kcrash/kcrash-5.249.0/src/kcrash.cpp:586 #4 0x00007620a3e5a770 in <signal handler called> () at /usr/lib/libc.so.6 #5 0x00007620760543cf in KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}::operator()() const (__closure=0x761da0251208) at /usr/src/debug/plasma-activities-stats/plasma-activities-stats-5.93.0/src/resultmodel.cpp:482 #6 std::__invoke_impl<void, KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}>(std::__invoke_other, KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}&&) (__f=...) at /usr/include/c++/13.2.1/bits/invoke.h:61 #7 std::__invoke<KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}>(KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}&&) (__fn=...) at /usr/include/c++/13.2.1/bits/invoke.h:96 #8 std::thread::_Invoker<std::tuple<KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}> >::_M_invoke<0ul>(std::_Index_tuple<0ul>) (this=0x761da0251208) at /usr/include/c++/13.2.1/bits/std_thread.h:292 #9 std::thread::_Invoker<std::tuple<KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}> >::operator()() (this=0x761da0251208) at /usr/include/c++/13.2.1/bits/std_thread.h:299 #10 std::thread::_State_impl<std::thread::_Invoker<std::tuple<KActivities::Stats::ResultModelPrivate::Cache::replace(QList<KActivities::Stats::ResultSet::Result> const&, int)::{lambda()#1}> > >::_M_run() (this=0x761da0251200) at /usr/include/c++/13.2.1/bits/std_thread.h:244 #11 0x00007620a34e1943 in std::execute_native_thread_routine (__p=0x761da0251200) at /usr/src/debug/gcc/gcc/libstdc++-v3/src/c++11/thread.cc:104 #12 0x00007620a3ea955a in start_thread (arg=<optimized out>) at pthread_create.c:447 #13 0x00007620a3f26a3c in clone3 () at ../sysdeps/unix/sysv/linux/x86_64/clone3.S:78 I feel like there should be more but I am not sure how to get it. Pressing enter simply prints the same thing again. Maybe this is enough but let me know if there is something else I can do. Thanks, that's helpful. Looks like this is the same as Bug 458121. *** This bug has been marked as a duplicate of bug 458121 *** Are you sure it's the same one? It doesn't actually happen to me at boot at all, just when turning off my monitor.
And I tried uninstalling kactivites and it still happens, now with a different backtrace:
Program terminated with signal SIGSEGV, Segmentation fault.

Well, it means there are multiple bugs. Perhaps one of them is Bug 458121. We can use this one for the original issue, which thanks to the debug symbols, I can now tell is in KScreen::WaylandConfig::setupRegistry(). Moving to KScreen. Appears to be solved with 6.0.2, closing for now. Indeed! *** This bug has been marked as a duplicate of bug 482768 *** |
