From the dmesg log it looks like there is a problem with your live CD. I'd suggest you download a new daily-live and burn it again.
In Xorg.0.log I found this to be strange:
drmGetBusid returned ''
It is also possible there are suspend issues on the live CD which do not arise when it is installed on a hard drive, especially if the CD media is mounted through USB, although that seems not to be your particular case.
