Hi

 

We are running Fedora 22 (64-bit) on a powerful workstation.  At the login screen the GUI is slow to respond: the mouse is jerky, particularly when hovering over user names, and using the arrow keys to traverse over user names sometimes jumps two names for one key press. 

 

Response after login is fine.

 

Please can anyone suggest the cause of this problem?

 

Best regards

 

David
