Created attachment 1172103 [details] screenshot Description of problem: I was running a session of my user (let's call it user A), when I had to start another session to let user "B" use the computer. So I selected "Change user", then "new session". Then I saw some strange screen behaviour, but I had not paid much attention to it. The new SDDM login screen was identical at the one you get when you do not have any other running users. I logged into user "B", then I got a xmessage screen "Could not start ksmserver. Check your installation". This happened 2 or 3 times before I managed to login into the system using user B. When I closed user B session, I have found out that my previous user A session was killed. In dmesg I have found some errors about sddm sddm[1105]: segfault at 10a0 ip 00000000000010a0 sp 00007ffda7756908 error 14 in sddm[5631bfdcc000+6b000] kactivitymanage[2664]: segfault at 7f3a80e5e670 ip 00007f3a7973f3b1 sp 00007ffd143e2d78 error 4 in libQt5Sql.so.5.6.0[7f3a79729000+45000] kactivitymanage[14187]: segfault at 7f07c4141670 ip 00007f07c40d03b1 sp 00007fffc77f57e8 error 4 in libQt5Sql.so.5.6.0[7f07c40ba000+45000] kactivitymanage[15365]: segfault at 7fd73ab4d670 ip 00007fd7380503b1 sp 00007ffc3d0ef498 error 4 in libQt5Sql.so.5.6.0[7fd73803a000+45000] # journalctl -b --no-pager | grep kac giu 24 20:54:23 machinekernel: kactivitymanage[2664]: segfault at 7f3a80e5e670 ip 00007f3a7973f3b1 sp 00007ffd143e2d78 error 4 in libQt5Sql.so.5.6.0[7f3a79729000+45000] giu 24 20:54:23 machineabrt-hook-ccpp[13040]: Process 2664 (kactivitymanagerd) of user 1000 killed by SIGSEGV - dumping core giu 24 20:54:23 machineaudit[2664]: ANOM_ABEND auid=1000 uid=1000 gid=1003 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=2664 comm="kactivitymanage" exe="/usr/bin/kactivitymanagerd" sig=11 giu 24 20:57:14 machineaudit[14187]: ANOM_ABEND auid=1000 uid=1000 gid=1003 ses=4 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=14187 comm="kactivitymanage" exe="/usr/bin/kactivitymanagerd" sig=11 giu 24 20:57:14 machinekernel: kactivitymanage[14187]: segfault at 7f07c4141670 ip 00007f07c40d03b1 sp 00007fffc77f57e8 error 4 in libQt5Sql.so.5.6.0[7f07c40ba000+45000] giu 24 20:57:14 machineabrt-hook-ccpp[15090]: Process 14187 (kactivitymanagerd) of user 1000 killed by SIGSEGV - dumping core giu 24 21:29:50 machinekernel: kactivitymanage[15365]: segfault at 7fd73ab4d670 ip 00007fd7380503b1 sp 00007ffc3d0ef498 error 4 in libQt5Sql.so.5.6.0[7fd73803a000+45000] giu 24 21:29:49 machineabrt-hook-ccpp[18023]: Process 15365 (kactivitymanagerd) of user 1001 killed by SIGSEGV - dumping core giu 24 21:29:49 machineaudit[15365]: ANOM_ABEND auid=1001 uid=1001 gid=1001 ses=5 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=15365 comm="kactivitymanage" exe="/usr/bin/kactivitymanagerd" sig=11 # journalctl -b --no-pager | grep Qt giu 24 20:54:23 machinekernel: kactivitymanage[2664]: segfault at 7f3a80e5e670 ip 00007f3a7973f3b1 sp 00007ffd143e2d78 error 4 in libQt5Sql.so.5.6.0[7f3a79729000+45000] giu 24 20:54:26 machineorg.kde.KScreen[2542]: Qt: Couldn't interpret the _XKB_RULES_NAMES property giu 24 20:54:26 machineorg.kde.KScreen[2542]: Qt: failed to retrieve the virtual modifier names from XKB giu 24 20:54:26 machineorg.kde.KScreen[2542]: Qt: failed to retrieve the virtual modifier map from XKB giu 24 20:54:26 machineorg.kde.kuiserver[2542]: Qt: Couldn't interpret the _XKB_RULES_NAMES property giu 24 20:54:26 machineorg.kde.kuiserver[2542]: Qt: failed to retrieve the virtual modifier names from XKB giu 24 20:54:26 machineorg.kde.kuiserver[2542]: Qt: failed to retrieve the virtual modifier map from XKB giu 24 20:54:26 machineorg.kde.kssld5[2542]: Qt: Couldn't interpret the _XKB_RULES_NAMES property giu 24 20:54:26 machineorg.kde.kssld5[2542]: Qt: failed to retrieve the virtual modifier names from XKB giu 24 20:54:26 machineorg.kde.kssld5[2542]: Qt: failed to retrieve the virtual modifier map from XKB giu 24 20:57:14 machinekernel: kactivitymanage[14187]: segfault at 7f07c4141670 ip 00007f07c40d03b1 sp 00007fffc77f57e8 error 4 in libQt5Sql.so.5.6.0[7f07c40ba000+45000] giu 24 21:29:50 machinekernel: kactivitymanage[15365]: segfault at 7fd73ab4d670 ip 00007fd7380503b1 sp 00007ffc3d0ef498 error 4 in libQt5Sql.so.5.6.0[7fd73803a000+45000] # journalctl -b --no-pager | grep KScreen giu 24 20:54:26 machineorg.kde.KScreen[2542]: Qt: Couldn't interpret the _XKB_RULES_NAMES property giu 24 20:54:26 machineorg.kde.KScreen[2542]: Qt: failed to retrieve the virtual modifier names from XKB giu 24 20:54:26 machineorg.kde.KScreen[2542]: Qt: failed to retrieve the virtual modifier map from XKB giu 24 20:54:26 machineorg.kde.KScreen[2542]: The X11 connection broke (error 1).

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
