The proposed solutions were:
delete wtmpx and wtmp files
purge more frequently such files
removing dtlogin from /erc/rcx.d/Sxxdtlogin
and modifying the file
"/etc/dt/config/Xserver" commenting out the line that starts with :0.
Any of the solutions work, however for our particular problem (machine with
CDE but without graphics card) we found the two last ones as the more
appropiate.
