@Joseph Thanks. I just installed both - linux-image-3.18.0-14-generic_3.18.0-14.15~lp1425252v1_amd64.deb and - linux-image-extra-3.18.0-14-generic_3.18.0-14.15~lp1425252v1_amd64.deb
Unfortunately the result was the same as with the previous 4.0.0.-040000rc1: Bluetooth doesn't show up in menu bar and in Settings -> Bluetooth everything is grayed out. WiFi works ok. Are there any logs or other info I can provide to you that would help? ---------------- :~$ uname -a Linux Cake 3.18.0-14-generic #15 SMP Fri Feb 27 18:38:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ---------------- :~$ dmesg | grep error [ 2.954299] EXT4-fs (sda5): re-mounted.
