When Jim logs in,  and the screen freezes,
login as root on the console, and do a ps -wwef | grep jim > /tmp/ps.jim

Next, do the same for Jan.

Compare the ps outputs to see just exactly what processes
jim is running that jan is not.
One or more of those processes might be the culprit(s).
If you do find these processes, check Jim's shell rc files
like
.bash_logout
.bash_profile
.bashrc

see if he might be invoking the errant process from these files.

If nothing found in the rc files, you have to suspect that one
or more app he is running may be infected, and should be replaced.

top will not should what is causing the freeze, only who is using
most cpu and who is using most ram ....etc.

Another thing to try is, when jim logs in, disable the network.
if it no longer freezes, he is running a program that is also
dependent on the network - without the network, the program
is crippled.  Find out which program.
