I have my Asus M5A99FX (with AMD FX6300 6-core processor and 16GB of memory) loaded with Debian Jessie and KDE. Everything seems to be working fine until I shut down the system. I click the shutdown command within KDE and seconds later the screen contains error statements ending with the statement kernel panic. I know this to be a kernel crash. I can logout which will return me to graphical login prompt where I can then go to a command prompt and Ctrl-Alt-Del and it will shut down correctly. It appears that if I do not let KDE shut the system down and do it manually it will work correctly. I am betting there is a bug in KDE that is causing this.My question is how can I disable to graphical login so I have to login from a command prompt? I don't mind having to giving an init6 or init0 command from a command line.
