Quote:trinidad: The microcode available will be in the Linux firmware package in synaptic. Install the package and then use driver search to select the microcode if you like.
I actually have linux-firmware installed, only intel-microcode is not installed.
I have assumed that intel-microcode is automatically installed by Ubiquity if an Intel processor has been detected, but it doesn't seem to be the case. It looks like intel-microcode is considered to be an optional package that must be installed by the user.
In the end I got kernel 3.13.0-141.190 and then intel-microcode installed. On my system it didn't work too well, I had experienced freeze-ups, so I booted to my Clonezilla disk image backup and rolled back to kernel 3.19.0-33 and no intel-microcode. I only have 2 GB of RAM on this machine so it could be the problem.
In case anyone else is considering trying this update I had to do the following to get the final initrd.img-3.13.0-141-generic built properly:
- install kernel 3.13.0-141
- purge kernel 3.19.0-33
- purge kernel 3.19.0-80 (which for some reason was auto-installed after 3.19.0-33 was purged)
- reboot
- install intel-microcode
Make sure that the last line in terminal output refers to kernel 3.13.0-141-generic:
Code:
sudo apt-get install intel-microcode
