LXDE - Lightweight X Desktop Environment

It's may bug of pam object of ecrypt.

when I debug the lxdm, I found pam stack add some event source to glib main
loop that cause lxdm to cpu 100%, which not related to lxdm itself.

As lxdm's goal is enough lightweit and don't want to develop complex
framework to deal these problems, so this won't fixed in lxdm's side.

if you want to workaround this, you can make a patch to lxdm like this

in lxdm.c lxdm_do_login function
add some code before
char** env, *path;

int i;
for(i=2;i<256;i++)
g_source_remove(i);

I don't think it's bug of lxdm.
I install the ubuntu 12.04 with encypted home, and can login with the lxdm
from ubuntu repo

when I look into pam stack, the guy of ubuntu already do the job, and the
command mount show that the home is mounted as ecryptfs.

I hate the ubuntu, I even can't find a way to default to run level3, so I
can't debug my lxdm there, if there are some bug only about to ubuntu,
maybe can't fixed.

In /etc/lxdm/lxdm.conf I have change "# xauth_path=/tmp" to
"xauth_path=/tmp" and rebooted the system. After a login on my desktop the
file /tmp/.Xauth1000 is created but lxdm-binary is still using 100% cpu
time of one core.

there are two usage of home directory in lxdm
1 create xauth file
2 login the user and switch to user directory

if 1 cause the problem, you may change the xauth file path at config file
[base]
xauth_path=/tmp

if it success, there will xauth file /tmp/.Xauth?????
