[ＵＧＰ <good5209 yahoo com tw>]

Hi,

I surf to LXDE website and download tarball for compile by myself.

It say need newer version gtk+ library, so I go to download gtk+ tarball too. And make install it.

When glib-2.22.4 install finish, I attend LXDE's deb files for install, I add lxde apt information and use apt-get install lxde.

Install finish, so I logout gnome and want login LXDE, but it happen this problem:
NVIDIA Logo -> orange screen, waiting cursor -> terminal screen -> NVIDIA Logo -> ...


Linux Environment: Ubuntu 8.04.3


cat /var/log/syslog | grep GLib:

I has tried these to solve this problem, but not work:

1.sudo dpkg-reconfigure gnome-desktop-environment
terminal say nothing after this.

2.sudo apt-get remove lxde openbox lxde-*

3.sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

4.sudo /etc/init.d/kdm start
terminal say kdm isn't default setting.

5.sudo aptitude remove xserver; sudo aptitude install ubuntu-desktop


How to solve it?
Thanks.
