    I have installed Ubuntu (ubuntu-8.04.1-desktop-i386.iso) in my 8Gb SSD. When i do turn on the Aspire One, the SSD led indicator is always blinking and it takes a while to stop (almost so many time as when i've had windows xp installed).
    When this led indicator is blinking i really can't do almost nothing because all the system is very slow. Even when SSD stops reading-writing and i try to open a program like firefox it takes 5 to 10 seconds to open it.

    My question is: Is this normal? Is there any possibility of tweaking Ubuntu to get a better SSD performance-quicker system response?

    I've realized that my Bios version it's not the latest version available at Acer-support-Drivers section, if i flash my bios with the latest version it will help?

    Thanks to you all for this great forum!!!

    Hi there, when installing ubuntu, did you use EXT3 or EXT 2? If you used the former, as it is a journalling FS it will access the SSD ALOT more than EXT2. There is a way to change to EXT2 once a system is installed, a quick search will give you great how to's.

    OR it could be something else?...

    To answer a question I came here to ask, then simply used Google and a friend...

    "How do I know whether I'm running EXT3 or EXT2 on my Ubuntu installation?"
    Go into Accessories > Disk Usage Analyser
    Choose Edit - Preferences and it'll show you in the window that appears.

    ...and the next obvious question is...

    How do I change from EXT3 to EXT2?

    You'll be wanting this guide:
    viewtopic.php?f=28&t=4768&p=32583&hilit=ext2+ext3+ubuntu#p32583

    ...except you want to add the word "sudo" in front of every command the nice man gives; and the default (for me) was /dev/sda1 and not /dev/hda5 as in this posting.

    I now have a *much* faster Ubuntu installation.

    Hi!
    Thanks for the post... but...
    When i use: "sudo umount /dev/sda1" it returns: "device is busy" if i use: "umount /dev/sda1" it returns: "only root can unmount..."

    Why?

    I have runned Accessories > Disk Usage Analyser
    Choose Edit - Preferences and just like you my SSD device is "sda1"...

    Not sure about ubuntu but generally in unix/linux.. Go to single user mode (sudo init 1) and do what you want, or use umount -f.

    ...or you could simply mount the filesystem(s) as ext2 (ext3 is just ext2 with journaling added). Edit /etc/fstab and replace ext3 with ext2 and you should be fine.
