Hello mrmazda and I_A:
Sadly, other kernels from GRUB menu selection didn’t work.
Also tried with other user account (I already had a user created before for my wife’s name) without any luck.
Anyway, as you suggested, I am going to install the whole OS.
I really appreciate your continuous support on this issue and it was really a learning experience for me.
But a question still remained unanswered, What happened after March 31 update ?
Nothing which is writeable by “world” and, the “.config” directory is empty …
Have you set-up something pointing to “/var/lib/sddm/.config/” in “/etc/sddm.conf”
[HR][/HR]It may be helpful if you could install a tool named “inxi” available from the standard openSUSE repositories and post the output of “inxi -F” after you’ve installed the packages indicated by “inxi --recommends”.
[HR][/HR]It may be that, because you’re still running KDE4, there’s some issues being raised which are caused by dependency required by the default KDE Frameworks 5 environment:
Please post the output of “zypper verify --details” and “zypper repos --uri --sort-by-alias”.
@jrahman:
Apropos Btrfs, are you absolutely certain that the weekly and monthly ‘cron’ jobs related to Btrfs housekeeping have been executed?
If not, “systemctl rescue” and then, with the user “root”, manually execute the Btrfs housekeeping scripts located in ‘/etc/cron.weekly/’ and ‘/etc/cron.monthly/’.
When the scripts have finished executing (may take more then a few minutes), reboot …
