I see the following on-screen for a brief moment when entering or leaving suspension:
(process:###): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
Any idea what this is, how I can get rid of it, and if it's something I should be concerned about? It's been happening ever since I installed 10.10 64-bit (fresh install) - I don't recall it ever happening under 10.04 64-bit.
It's nothing to worry about and happens to all users, as far as I am aware. It's actually there when you boot too, just covered over by Plymouth and then by your login screen.
