I found that the stack canary protector (stack smashing detector) is aborting udisksd from time to time. And plasmashell could not start udisks2 because of this, so the desktop could not start up. I ran `snapper undochange` to revert the last dist-update, then ran `zypper al udisks2` to lock udisks2. After another dist-update, I logged into plasma desktop successfully. Now the version is `cpe:/o:opensuse:tumbleweed:20230926`. There are two issues may be useful: - <https://github.com/storaged-project/udisks/issues/1152> - <https://github.com/storaged-project/udisks/issues/1193> It seems that libblockdev-3.0.3 will fix this problem? This is actually a reply to <Login issues after recent Tumbleweed update> but idk why my mail server is not delivering mails correctly, sry.
