Problem occurs about half the time on boot (race condition?) in Kubuntu 10.04. Instead of starting kdm, boot drops to a blank screen with an irrelevant error message:
(Process:301):GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
Ctrl-Alt-Del and the power button can be used to restart or shutdown the computer, no other combinations I've tried do anything (e.g. Ctrl-Alt-F1, Ctrl-Alt-Backspace, any combination of Ctrl, Alt, Shift and PrtSc or Pause).
Every ~38th boot, a full disk scan is performed before starting kdm, and this issue has never occurred following such a disk scan. Note: small sample size.
Known to exist with
vmlinuz-2.6.32-22-generic
vmlinuz-2.6.32-23-generic
vmlinuz-2.6.35-020635rc1-generic (mainline kernel)
The mainline kernel worked happily for quite some time, but has now failed several times.
Workaround: Boot in recovery mode, resume normal boot, sudo kdm.
I have only one monitor, but it's a laptop so there is the potential for a second screen, if that's relevant.
This looks like a duplicate of Bug 572279
Because it's impossible to create a bug report when the bug appears, I'll be attaching a variety of log files going back a bit further.

Problem occurs about half the time on boot (race condition?) in Kubuntu 10.04 (something similar may have happened to me a couple times in 9.10, but with no error message). After splash screen, instead of starting kdm, boot drops to a blank screen with an irrelevant error message:
(Process:301):GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
Ctrl-Alt-Del and the power button can be used to restart or shutdown the computer, no other combinations I've tried do anything (e.g. Ctrl-Alt-F1, Ctrl-Alt-Backspace, any combination of Ctrl, Alt, Shift and PrtSc or Pause).

The mainline kernel worked happily for quite some time, but has now failed several times. I'm not convinced this is a bug in the kernel.
Workaround: Boot in recovery mode, resume normal boot, sudo kdm.
