Hi guys.
Actually I 'm a newbie in GNU/Linux (about 9 month experience) and I have Kubuntu 17.04 now I have a problem to login session after 4 month.
When I enter my password to login and after Plasma loading, a black screen will shown with cursor, that's all I have (panels and... won't be appear), but all the services are run and I found that when I open Konsole with shortcut key and enter

Code: Select all

htop

in it and I saw packages and programs are run so I think there is a problem with some parts of Plasma and I know that a log file is require to help but I don't know how to access this file then please tell me How can I access this file and I will send it here.
If anything else in needed tell me what should I do?
-Thanks a lot.

Doesn't anyone know that how can I solve this problem ?
