This is a new install testing the systemd init system on postmarketOS. I get this crash when attempting to start the system. #0 0x0000ffffa930cc4c in QArrayDataPointer<KWin::Output*>::QArrayDataPointer (other=..., this=<synthetic pointer>) at /usr/include/qt6/QtCore/qarraydatapointer.h:38 #1 QList<KWin::Output*>::QList (this=<synthetic pointer>) at /usr/include/qt6/QtCore/qlist.h:70 #2 KWin::Workspace::outputs (this=0x0) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/workspace.h:782 #3 KWin::DpmsInputEventFilter::notify (this=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/dpmsinputeventfilter.cpp:111 #4 0x0000ffffa930cddc in KWin::DpmsInputEventFilter::~DpmsInputEventFilter (this=0xffff8a48cbd0, __in_chrg=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/dpmsinputeventfilter.cpp:37 #5 0x0000ffffa930ce54 in KWin::DpmsInputEventFilter::~DpmsInputEventFilter (this=0xffff8a48cbd0, __in_chrg=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/dpmsinputeventfilter.cpp:38 #6 0x0000ffffa94f7900 in std::default_delete<KWin::DpmsInputEventFilter>::operator() (__ptr=<optimized out>, this=<optimized out>) at /usr/include/c++/13.2.1/bits/unique_ptr.h:93 #7 std::unique_ptr<KWin::DpmsInputEventFilter, std::default_delete<KWin::DpmsInputEventFilter> >::~unique_ptr (this=0xffff97ce3a30, __in_chrg=<optimized out>) at /usr/include/c++/13.2.1/bits/unique_ptr.h:404 #8 KWin::Workspace::~Workspace (this=0xffff97ce3710, __in_chrg=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/workspace.cpp:475 #9 0x0000ffffa94f8154 in KWin::Workspace::~Workspace (this=0xffff97ce3710, __in_chrg=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/workspace.cpp:475 #10 0x0000aaaae80397e4 in KWin::ApplicationWayland::~ApplicationWayland (this=0xffffd7894ed0, __in_chrg=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/main_wayland.cpp:126 #11 0x0000aaaae8004d94 in main (argc=<optimized out>, argv=<optimized out>) at /home/buildozer/aports/community/kwin/src/kwin-6.0.3.1/src/main_wayland.cpp:610

Git commit 3ed535dd6729263fbeac3d77607126b22500ab05 by David Edmundson. Committed on 15/04/2024 at 22:03. Pushed by davidedmundson into branch 'master'. Remove superfluous wake in dpmsinputeventfilter destruction Workspace already makes sure to only dynamically delete the dpmsinputeventfilter if all screens are currently on. This line to wake all screens is therefore redundant. It's problematic as it can cause a crash on final teardown when workspace is destroyed.
