This morning, a number of my users reported problems logging into their SuSE 9.1 machines. After entering their authentication details the login process hangs. All these machines are running kdm/kde. We found that if the users choose a different window manager they can log in. I created a new local user and could the login to kde using the new account. I deleted all the dot files and directories from the users home directory and found that the kde login was successful, but very slow - about 3 minutes! However, starting a new window within X, such as an xterm, is now very slow. I ran `nice top` in an xterm and then fired off another xterm, again it was very slow to load, but during this time there was < 5% CPU activity and little or no disk I/O. There were no problems yesterday - this all started this morning - any ideas? -- Simon Oliver
