    Ubuntu 12.10 Boot problems(Boot Repair log)

    Hi, first post, very new to Ubuntu(Linux as a whole really) But I have had Ubuntu 12.10(64bit) installed for a little over a week now and am experiencing problems on boot up. When my computer is started up, I am greeted with the grub 2 screen, with the following options: Ubuntu,advanced options for Ubuntu, and the 2 different memory test. I beleave all my problems started with the installation of acidrip, and devede(both from the repository). I have since removed both of them(again via the repository). Everything seemed to uninstall fine so I did not note what the terminal kicked out. I can usually get into Ubuntu after selecting "Ubuntu" from that grub2 screen a couple of times after restarting.

    I ran boot-repair per this https://help.ubuntu.com/community/Boot-Repair and ended with the following URl http://paste.ubuntu.com/1503119/.

    Im hoping this isn't hardware related but just in case

    Intel core 2 extreme cpu
    EVGA 790i ftw motherboard
    4gb mushkin ram
    EVGA GTX 260 grapthics card (not showing under All Settings then Details)
    Intel 120gb SSD

    (I may have missed something or other, will add if I remember)

    If you are consistently getting to grub menu, I do not think Boot-Repair will help. That is more for fixing grub issues. I might add a boot parameter if needed, but you did not need those before?

    I would look in the logs to see if it is reporting anything. I look at dmesg and look for long times between entries, out right errors, or a drive trying to load multiple times & then maybe failing or working. Use Log File View or look in /var/log/dmesg


    Did you enable trim on SSD? And AHCI in BIOS?

    No I did not enable trim on my ssd, or AHCI in my bios... Should I? I'm not quite sure what either of those are, but I will go and google them.

    *Update* I did some reading and enabled trim. This made the Ubuntu load smoother after I select Ubuntu from the GRUB screen. Unfortunately my motherboard only supports AHCI if I open the case and switch from NVIDIA on board controller to a Jmicron controller, and I've read that will slow my system down. I'll do it is thought to correct this issue, but I would rather not.

    Trim does not work without AHCI.

    I have used this command and I think this poster believes it is a better way than trim. I ran this command as I had not enable trim initially and got these results.
    fred@fred-Precise:~$ sudo fstrim -v /
    /: 23267893248 bytes were trimmed
    https://wiki.archlinux.org/index.php..._Cell_Clearing
    sudo hdparm -I /dev/sdX
    Alternate to discard, call fstrim via cron
    http://opensuse.14.n6.nabble.com/SSD...td3313048.html
    test if trim working using hdparm

    https://wiki.archlinux.org/index.php/Solid_State_Drives

    With SSD or Flash drives, Use ext4 without journal:
    sudo tune2fs -O ^has_journal /dev/sda1
    sudo tune2fs -o discard /dev/sda1
    No swap or set swapiness or install 'Dynamic Swap Space Manager' from the Ubuntu Software Center
    After installing, change the fstab so that everything gets mounted with noatime.
    Make sure BIOS is in AHCI mode for trim to work.
    change to noop i/o scheduler

    Ok, thanks I'll try that when I get home(night shift)

    On a side note, would you call this a sloppy install? since this is only a week and some days old and I really don't have much on this system, could it be easier just to start over brand new and fresh?
