When the user tries to log in using kdm, and his home directory is
full, the user is thrown out to the login screen without any
explanation. I believe the user should get some kind of error message
displayed on the screen when this happen, to avoid confused users and
a lot of work for the system administrators having to answer questions
from the confused users.
I've tracked the problem into /etc/X11/XSession, where the login will
fail if XSession is unable to create the ~/.xsession-errors file.
This problem is reported using the message() function, but this
function only prints a message to stderr, and do not display anything
on the X display.
I suggest changing message() to check if $DISPLAY is set, and in this
case both pop up a dialog with the message and print the message to
stderr. Something like this:
message () {
# pretty-print messages of arbitrary length
echo "$*" | fold -s -w ${COLUMNS:-80} >&2;
if [ ! -z "$DISPLAY" ] ; then
xmessage "$*"
fi
}
This would make it easier to detect why the login fails.
