View Full Version : [kubuntu] SDDM goes to black screen with "X" cursor after timeout.

I'm having a problem on several (four at least) machines. When the system boots, if you do not log in, the screen usually changes to a black screen with an "x" for a cursor. You cannot select anything or type that I can tell. Sometimes the login screen is still displayed with the "x" cursor, but you cannot enter a text box to type. You can switch to a terminal, however. The same behaviour happens after logging out and letting the screen sit for a while. This does not happen when I lock the screen while logged into KDE. All machines are running Nvidia with nvidia drivers. It seems somehow to do with the timeout or screen saving. The only way I have been able to fix the situation is reboot, which is incredibly inconvenient.

Any suggestions?
