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!
I sure hope you archived or somehow saved those files, first. If I were one of those users, I'd be furious if all my configuration information were summarily discarded just to diagnose a performance issue!!
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.
Most often symptoms of great slowdowns without large CPU or disk loads are an indication of some network activity that is not being responded to in a timely manner. Typical of these are DNS queries or YP / NIS / LDAP lookups or NFS access failing to get a response (at all or with the usual latency).
There were no problems yesterday - this all started this morning - any ideas?
