Ubuntu 14.04-CPU Core Detection & Touch-Pad

**squakie** · June 9th, 2014

Okay - the microcode is available right in ubuntu:

sudo apt-get install intel-microcode

It will install another package that is some type of manager for switching between firmware releases, but for now I would just install it and then reboot.

See if your CPU information has changed.

If it does, we can move on to the touchpad thing.

Also: for AMD users there is also an amd-firmware package you can install.

These firmware packages are for corrections/additions to the firmware built in to the processor. I personally never knew these existed before. Might not be a bad idea to install the correct one for your processor brand and maybe it will be caught in the updates after that also if it changes in the future for more additions/changes.

Hi sudodus i update the bios the last version is the 208 as in my initial post. I still can't find any solution? Some people tell to change to linux mint or debian. But maybe i have the same issues there too. There is another option, because i installed ubuntu 14.04 in my desktop computer at office and works fine.

Hi squakie thanks for you reply but i install the intel-microcode and just 1 processor was detected after the reboot.

Sorry that didn' t help - that was about the only left from the things I found, and I honestly thought it would help. Oh well. This is beyond my skill leves at this poin so I'm bowing out. Sory, and best of luck!

I have no more ideas to get 14.04 LTS recognize all cores ... but I can suggest

1. to follow what you thought of already, to try other linux distributions. And in this case, I suggest that you try distros that are not closely related to Ubuntu, but more distant relatives. I think Linux Mint might have very similar kernels. Debian is more different, Fedora and OpenSuse are even more distant (to mention a few of them).

2. to give up the newest version (14.04 LTS) and try with the two year old version Ubuntu 12.04 LTS which has long time support until April 2017. It is well debugged and polished, and it might work better with your hardware.

I do suspect it's firmware related - the processor is recognized but the actual number of cores isn't. A lot of times that has been problems with either the processor not identifying itself correctly, the motherboard BIOS not recognizing it correcly, the firmware in the OS, or something in a kernel module that isn't picking these up. I would do as sudodus says:

- try an older supported version with an older kernel

- try a non-debian based distro. Indeed Mint is actually based on ubuntu, so i would stay away from it also.
