I updated my Manjaro-Arm packages today (last update was done about 5 days ago) and now when the system boots up instead of the graphical login screen I get a black screen. The boot process works fine and the system is up, only the graphical login fails to start.
journaltcl --since=today reveals the cause:
ssdm-greeter: Cannot mix incompatible Qt library (version 0x50c00) with this library (version 0x50c01)
systemd-coredump: Process 719 (sddm-greeter) of user 994 dumped core
Since I have no graphical desktop I tried to see if I missed a package update by running: pacman -Syu but it it says: “there is nothing to do” So my system is up to date, but this update seems to have caused a mix of incompatible libraries to be installed.
