Thanks. I can't see anything obvious in that log. This makes me think something is running fundamentally too slow; either the CPU or the disk.
To check the disk speed please run a benchmark in the 'Disks' app, and/or use: sudo hdparm -t /dev/sda and tell us the results. The CPU sounds like it might be restricted by thermald. Please try removing the file: /etc/thermald/thermal-conf.xml because it sounds like there's a problem in that file. ** Package changed: gnome-shell (Ubuntu) => ubuntu ** Summary changed: - system booting is too slow.
