I changed my grub boot options to add "vga=0x323" to them to resolve some issues with corrupted display during startup/shutdown on my laptop.

The next time I booted the system up, I got a warning over the login screen saying

Xfce Power Manager

HAL Daemon not running

The keyboard and mouse are unresponsive. After a minute or so, they start to work and the system functions as normal.

How can I solve this?

does the issue go away if you boot without the "vga=0x323" option? – quack quixote Feb 7 '10 at 20:55
@quack - No, it went away about two weeks later after installing some updates. – Macha Mar 28 '10 at 16:14
you should post that as an answer instead of accepting an incorrect (or at least unverifiable) answer. – quack quixote Mar 28 '10 at 20:29

So apparently this problem is in some way related to the CD drive. If you have a CD in the drive then try removing it. I have no idea why this would make any difference, but it works for me, no CD, no error. Obviously this isn't a real fix, but it's an easy work around until the real problem is found and fixed.

This worked for me. Cloned a drive, and the new drive gave an error if the LiveCD I used to clone it with was still in the drive. Removed and all was well – SSumner Sep 3 '13 at 20:52

A system update, about two weeks after posting this question, solved the issue.
