    Default zypper install of dolphin-plugs cause kwin aborts -restore from backup result in SDDM segfaults

    Hi:
    Yesterday I used zypper to install dolphin-plugins(Stack exchange indicate that I need to do this to get a dropbox client). zypper says it had to change vendor and it installed a large number of packages. After the install KWIN was aborted several times and an attempt to rollback with yast-snapper hung in the middle. So I decided to restore a full file backup from Jun 1st and reinstall grub (This procedure has worked before for me). I booted okay the first time and I was able to login to KDE but after I shutdown and rebooted SDDM started getting segfaults and the login screen will not accept input. A portion of the journalctl log follows:

    Please show
    Code:
    zypper lr -d
    My suspicion is you used a TW one-click.

    Your posted log entries are certainly relevant but starting with "input panel unavailable" only displays your problem, not anything that caused it... So, it's incomplete.
    If you don't know what other entries to post... you should post the entire bootlog to a pastebin for inspection...
    But,
    That may not be necessary.
    You know the exact time and day your problem was caused,
    So, you should be able to resolve by simply picking a time and date prior to your problem and roll back to that point.
    In fact, you can probably roll back to any snapshot before that and after the last time you installed an app... All those intervening snapshots were probably caused by bootups and system updates/patches which can be re-applied... So, if for instance before those dolphin plugins if you hadn't installed an app for at least a week before that then you can roll back to any of about a week's worth of snapshots.
    Then, "zypper up" after your rollback.
