    A few weeks ago, a weekly update resulted in KDE failing to start ;
    as it needed to be updated anyway, I have been using Fluxbox instead.
    During the past few days, I removed all the old KDE pkgs,
    did an update of all the Qt pkgs which were installed
    & re-installed all the previous KDE pkgs in their new versions,
    so that I now have Qt 5.15.17 + 6.9.1 , KDE Frameworks 6.13.0 ,
    Plasma 6.3.5 + Apps 25.04.2 .

    I use OpenRC with 'startx' + '.xinitrc' :
    for Fluxbox, the latter is simply 'startfluxbox' ,
    for KDE, it's 'exec dbus-launch --exit-with-session startplasma-x11',
    which worked with the old version of KDE & is recommended in Gentoo Wiki.

    Now when I enter 'startx', I get a black screen + a movable mouse-pointer, but nothing else, & have to restart the machine & return to Fluxbox.
    There is an error msg : "$DISPLAY is not set or can't connect to server".

    Gentoo Wiki seems to recommend using 'sddm' instead of 'startx',
    which it describes at "the old method". I have 'elogind' 2.55.17 installed.

    I've looked at the logs in /var/log , but can't see anything relevant.

    Can anyone suggest what may have gone wrong ?
    Might it be advisable to use 'sddm' in future ?

    EPERM and EACCES usually are the critital errors you must find.
    Also you could see at the end "killed by SIGSEGV or something like this",

    I've checked all 3 terms & see no sign of a critical error.

    Does anyone else have any advice ? Has no-one else experienced this ?
