Very slow login on Ubuntu Karmic

Very slow login on Ubuntu Karmic

"A few days ago I installed Ubuntu Karmic (alternate i386) on my PC. Everything is working fine, except that after I insert my password at GDM it takes ages to get to the desktop (about 16 seconds).
Since I'm using LXDE I'd think login should be quite quick.. Any hint on what I could check?"

"This is not exactly an answer, but more of a collection of ideas on how to track down your problem. In my experience, these kind of delays happen because of one of the following:

Real need for processing lots of stuff.
Run out of RAM and use of swap-space.
Waiting for a service that either takes time to start, either fails entirely to start (so that the computer waits for the request to time-out).

You could try to investigate more by running on a TTY (ctrl-alt-F2, for example) the programs top (show you CPU usage) to rule out #1 and mem (shows amount of used memory) to rule out #2. Of course you should do this while on the graphical console you start your GUI session.

If it's #3, then you should investigate your logs. You could use bootchart as suggested in furtelwart answer (+1) or looking at the logs directly. All relevant logs in ubuntu are under the /var/log directory. I use Gnome/GDM and my logs are stored under /var/log/gdm. Chances are yours will be under /val/log/lxde.

Check your /etc/hosts and /etc/resolv.conf for invalid localhost entries. Remove them and the problem should fix itself.
