Hi,
after an hw update kde seems to not start anymore for a user whose home is encrypted with dm-crypt. I configured the automount at login as here, with the (bugfix?) modification mentioned here.
After typing the password in sddm the screen freezes, I can still move the mouse and pass to another console, but nothing happens. Here is an excerpt of journalctl.

However, kde seems to not start. Anyone has an idea? Perhaps some wrong dependences of system services?
The weird thing is that, for a user with no encrypted home, everything works perfectly. Also, the problem has appeared after I upgraded the hd, simply copying with cp -a the old root partition to the new one.
Edit: marked as solved

It turns out it was a simple permission problem. Somehow the home directory had owner root and permissions not to write for the user. Most probable cause: in order to copy the home from the old to the new hardware, both old and new partitions were mounted as root. Problem was solved by (after logging via console with user, and giving su)
cd /home/user
chown user:user .
chmod go-wrx .Offline
