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 Kubuntu forum also.

Not sure if this has anything to do with your problem or not, but often I've found that when I had problems at login with Kubuntu, it was because a vital KDE package had been removed in an upgrade. A "sudo apt-get install kubuntu-desktop" usually doe the trick for me. You can do this by choosing "Recovery console" from GRUB, logging in, entering the install command to the left and then rebooting with "sudo apt-get shutdown -r now"

Hope this helps!

Thanks for all replies.

The problem was more serious than I first thought. I was getting hangs all over. I have concluded that there must have been an upgrade of the proprietory nvidia driver which caused the problem. It has been totally cured by a switch to the X-org nvidia driver

However I am still getting:-

kdm_greet[2820]: Cannot open default user face
