    That's a non supported scenario.

    Ok, but the system is completely up-to-date (zypper up has nothing to do) and I doubt the problem is here.

    Also the two systems (desktop and laptop) were completely stable before the update

    Thanks

    the problem is you doubt where the problem is, but you can't assume
    that is _not_ the problem because zypper only installs new
    software...it does not dump no longed need bits of code which were
    not replaced, or config files of the old software that may not be
    right for the new, and other stuff--lots of other stuff....there are
    reasons for the written upgrade methods...

    ignore them and you will have problems...random freezes, maybe..
    can't log in, maybe.. libreOffice does strange stuff, maybe....cpu
    overheating, maybe...graphics all messed up, maybe....etc etc etc..

    and, picking bits from one of the three methods and inserting those
    bit into another or just skipping some . . .

    So DD, what do you recommend apart from a clean re-formatted install?

    Or to reformulate into questions:
    1. Does the iso disk upgrade option differs in any sort of substantial way from zypper dup?
    2. I have followed to the line the online (zypper based) upgrade instructions on this site. Are these to be disregarded?

    Thanks again for your help

    i don't recommend anything apart from a full format and clean install
    (saving data and configs [just in case] to a safe off machine place
    first, of course).

    that is exactly what i do every time i move from one version to
    another....others have good luck with one of the three documented
    upgrade methods..

    and some others have bad luck and have to resort to a clean format
    new install and bring in their data from that backup...which is a
    step in all three methods:

    1. http://tinyurl.com/35p966c "due to some third-party packages and
    the myriad of possible configurations, it is possible for some
    combinations to cause failure upon upgrade. It is very important that
    all important data is backed up prior to beginning the upgrade process."

    2. http://tinyurl.com/93uemsr "copy the old configuration files to a
    separate medium (such as removable hard disk or USB flash drive) to
    secure the data. This primarily applies to files stored in /etc as
    well as some of the directories and files in /var. You may also want
    to write the user data in /home (the HOME directories) to a backup
    medium...Depending on your customizations, some steps (or the entire
    upgrade procedure) may fail and you must resort to copying back your
    backup data...Before actually starting the upgrade procedure, check
    that your system backup is up-to-date and restorable. This is
    especially important because you must enter many of the following
    steps manually."

    3. http://tinyurl.com/7l4m2td "...the live upgrade, it is to be
    considered a "best effort": it should work, but it can also fail. It
    is strongly recommended to make a full backup previous to the
    undertaking. If the upgrade fails, you can then restore and try
    again, changing whatever is needed to avoid the previous problem,
    install fresh, or attempt a live upgrade."

    now! you asked _me_ what _i_ recommend and i gave that above...
    listen to others (these are opinons after all) and you will hear that
    the third method above can be used to *sometimes* rescue a failed
    upgrade...i believe by following from step 7 "After the upgrade" and
    onward, but i have never done that . . .

    OH! and it *is* possible that you may be experiencing any of a number
    of other problems encountered by others running 12.3--there are lots!!

    i am not the only one here who values stability, dependability,
    predictability over new and glitz....which is why i'm running 11.4
    Evergreen.

    Thanks dd for your help.

    Clean install will be!

    Luckily for many years I had /home and /data in separate partitions and have an automated (perl) regular backup plan for relevant parts of the system like /etc, /var, /home, /data ... That has kept my data integrity throughout many upgrades and a couple of hardware crashes, like loosing one disk, motherboard and RAID failures.

    I have been somewhat conservative with upgrades too, but:
    - wanted to move up my desktop from 12.1 due to a very bad experience with Nepomuk and Akonadi
    - wanted to move up my laptop from a very stable 11.4 to play with KDE source and patches while on my commuter train to work

    Quoting RMS: good hacking to all of you

    welcome...let us know how it goes...i have my fingers crossed that
    the freezes are history....but, if they are not *at least* we will
    have excluded the upgrade as a potential cause..

    there are many who have had exciting luck with 12.3, so . . .

    So was I - until the 7 yo Lenovo went tits up. The local Sam's manager
    offered me a deal on a killer HP tower he couldn't sell so I wound up
    changing from a dual-core AMD cpu to an 8-cpu Intel box with a totally
    different video subsystem and UEFI firmware. 11.4/Evergreen doesn't support
    efi so it was easier to switch than fight ;-)

    Yes.

    And where did you read that 11.4 to 12.3 was supported? It may work, it
    may not. Unpredictable.


    I would recommend that, before doing a clean install, do a DVD oflline
    upgrade to 12.3 from the current broken 12.3. Later, follow the
    instruccions post-upgrade in the wiki.
