Hi!
Can anyone help?
I've got Ubuntu 10.04 LTS - the Lucid Lynx installed, and I rebooted it today, because it seemed a bit sluggish, bit sluggish, and ever since I've had problems logging in and/or authenticating.
The only thinks I recall changing are there were a few updates downloaded, and I'd tweaked my Samba config file (smb.conf) and also been playing with the nvidia driver settings, enabling it and disabling it. This machine's a server, and it controls it's own logins, i.e. it doesn't authorise them somewhere else. When I reboot it, I see the greeter, I type in my password, and then it sits there for ages - at least a minute, before I see the logged in desktop. I can try switching to a virtual console (alt-f1 etc) and logging in there, and it takes ages and usually times out (timeout after 60 seconds message).
It also happens if I try to ssh into the machine.
Once the machine has been up for a while, the login response on a virtual terminal seems to be better, but I also get the problem using SUDO. I also get the problem logging in to Thunderbird on this machine, which uses IMAP to get the mail of this machine, and uses PAM to authenticate.
I've looked in the logs and can't see anything obviously wrong. ISTM that this is a problem with PAM authentication, but I've not changed anything, nor do I know what to do about it or what to change.
I've installed Bootchart, but there's nothing obviously wrong with that.
Any ideas?
Check that the machine can resolve DNS. I've seen quite big delays in logging in and especially when using sudo when a machine has unreachable/unresponsive DNS servers.
