Hangs on password entry panel during boot

[hg21]

Hi,

For the last week or so when I boot and get to the login panel the system hangs for a long time. The mouse cursor will not move and keyboard input of my password does not work for a couple of minutes or so.

Kernel details and extract of syslog below.
From the syslog the following seem to be the likely problems:-

kdm_greet[3168]: Cannot open default user face

console-kit-daemon[2693]: WARNING: Couldn't read /proc/2692/environ: Failed to open file '/proc/2692/environ': No such file or directory.

Any help will be gratefully appreciated. I'll put this on the KDE forum also.

I found this was a more serious problem than I first thought. I think the Nvidia nvidia driver was updated and messed up the graphics. Switching to the X-org nvidia driver has made the problem go away.

However syslog is still showing the errors:-

kdm_greet[3168]: Cannot open default user face

console-kit-daemon[2693]: WARNING: Couldn't read /proc/2692/environ: Failed to open file '/proc/2692/environ': No such file or directory.

but they don't seem to cause an obvious problem
