Hello friends....
I installed Debian linux 3.0 and I have a problem with display manager.. My system is booting in GUI mode well. When I give user name and password then it is comming desktop enviroment for a moment and it is comming login window again and again.....
I receive the following error in a little window at right bottom of screen....

april 15 12:00:00 (none) PAM_linux[240]: (xdm) Session closed for user root
april 15 12:00:00 (none) modprobe : can't locate module char-major-13
april 15 12:00:00 (none) kernel : neighbour table overflow

Please give your comments......................thanks

strange.....

here is a possible workaround....

edit the file /etc/inittab

look for the line "id:5:initdefault:"
and change it to "id:3:initdefault:"

now you will be presented with a text based login screen.

after login, give the command "startx"

if you like, you could run this command "echo startx >> ~/.bash_profile"
which will automatically run the startx command after login.

does that get you into a working desktop environment ?
