KDE plasma and SDDM installing on new clean system

Just install clean archlinux32 through general guide.
Then try

pacman -S plasma-meta

There were problem with rav1e (needed 0.32), mkinitcpio (needed 38) and explicitly pacman -S icu76

systemctl start sddm

Xorg has started but with black screen and mouse cursor only

Could only stop sddm from another terminal.

Therefore try to start plasma standalone

$ /usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland

/usr/bin/startplasma-wayland: symbol lookup error: /usr/lib/libQt5Quick.so.5: undefined symbol: _ZN14QDistanceFieldC1E5QSizeRK12QPainterPathjb, version Qt_5_PRIVATE_API

So I have some problem with qt versions?

Can anybody help and explain?

Re: KDE plasma and SDDM installing on new clean system

Seems QT dependencies are broken:

$ startplasma-wayland
startplasma-wayland: symbol lookup error: /usr/lib/libQt5Quick.so.5: undefined symbol: _ZN14QDistanceFieldC1E5QSizeRK12QPainterPathjb, version Qt_5_PRIVATE_API

And seems video driver too:

(in xerm)

$ glxinfo
name of display: :0
Error: couldn't find RGB GLX visual or fbconfig
