    Angry Ubuntu 14.04-CPU Core Detection & Touch-Pad

    Hi everyone i just installed ubuntu 14.04 in mi notebook and i have a lot of problems
    1. Just detect 1 processor of an core i5 (windows detect the 4)
    2. The touchpad and the function key doesn't work either.

    I think the core issue is very different from the other two issues.

    If we can solve one of the issues quickly, we can change the title to cover the remaining problem(s)

    I think you are better off getting help for the different issues in different threads (with good titles, that attract those who know about it and can help).

    Anyway, I suggest that you do a few things to make it easier for us to help

    1. Install and run htop

    Code:
    sudo apt-get install htop
    Code:
    htop
    htop should show 4 lines at the top (one for each core)
    Code:
      1  [||                        2.6%]     Tasks: 125, 248 thr, 61 kthr; 1 runnin

    My outputs are

    alfaceor@rolandito:~$ cat /proc/cmdline
    BOOT_IMAGE=/boot/vmlinuz-3.13.0-29-generic root=UUID=9f7542a5-7d1c-4986-9470-677df22ce97d ro acpi=off quiet splash vt.handoff=7

    I can't copy and paste this is the output of htop
    Windows detect the 4 cores and the touchpad i use ubuntu before (8.04) and have no problems.
    By the way i install ubuntu 14.04 with the apic=off option because the normal installation doesn't work, and in the installation process the touchpad doesn't work either.

    I try to work with ubuntu but maybe i must return to windows, please some help will be appreciated.

    Re: Ubuntu 14.04-CPU Core Detection & Touch-Pad

    htop also detects only one core.

    Please describe your computer. It makes it easier for us to help.

    - Brand name and model of the computer and/or the motherboard
    - CPU: Intel(R) Core(TM) i5 CPU M 430 @ 2.27GHz (you told us already)
    - RAM: size
    - graphics chip/card
    - wifi chip/card

    -o-

    - Try extensively different boot options, not only one each time but also combinations. You can try live (without installing) until you find a good combination.

    - It might be easier to succeed with the previous long time support version, Ubuntu 12.04 LTS.

    - Did you try the 32-bit or 64-bit version of 14.04 LTS? It might work better with the other one.

    The following will display the wifi card .
    Code:
     lspci
    I'm currently using similar hardware on an HP Elite Book W/ 14.04.

    I think Ubuntu has problems talking to the computer at a rather basic level. Sometimes it helps to update the BIOS/UEFI system. You can check if there is a new version for your computer.

    For a shorter list:

    lspci | grep Network
