    Unhappy mouse lagging in Ubuntu 12.04 in my Atom laptop

    I have a Netbook with an Atom N450 CPU and 1 GB memory.
    When I currently upgraded to Ubuntu 11.10 from Ubuntu 10.04, I have found that the new unity desktop is so sticky Especially when I open the libre office, almost everything sticked including the cursor !

    So I made a decision to upgrade to Ubuntu 12.04 although it haven't been released yet. However, it is much faster running on my Atom netbook, I think that is probably because hardware acceleration is supported.

    Nevertheless, that problem still exists: when I switching a tabs to another in Google Chrome, for example, My hard disk is reading continuously for a while, and the CPU usage is extremely high ( almost 100 % ).

    Despite the usage of CPU, a cursor shouldn't have been sticked on the screen any way when I was using Ubuntu 10.04 and Windows Xp. It isn't a great matter, I was annoying, though. Is that anyone can explain this problem, or is that possible to solve it ?

    Thank you

    Hello and welcome to the forums.

    I have moved the thread to the ubuntu+1 sub-forum where folks testing 12.04 beta may be able to help you.
    Thank you for your contributions. "So long and thanks for the fish!"

    if things are slow, they might be for several reasons. try checking what process is using the CPU the most and also see if you are using large amounts of swap.

    you can do it with "top" in the terminal or just using the system monitor from the dash

    as always - 12.04 is still not ready so upgrading from an older system can actually result in some different issues compared to fresh install. If I was you, I would back up all data and install 12.04 from an daily image

    I think that 'vanilla' Ubuntu is slow because it has too much 'eye candy'.

    Either you tweak the desktop environment, so that it will demand less horsepower, or you try other flavours of Ubuntu

    - Xubuntu with XFCE has a small foot-print
    - Lubuntu with LXDE has an ultra-small foot-print.

    - as suggested by meborc: install a fresh 'vanilla' Ubuntu 12.04.

    Anyway, download iso files for these flavours and try them live before installing.

    Thanks.

    I saw someone in the forum posted such a solution about how to solve this problem, I would like to try it first.

    Adding the following line in /etc/modprobe.d/local.conf

    options drm_kms_helper poll=N

    Then restart.

    I have tried Lxde on Ubuntu 12.04. And I felt in love with it at once due to its high efficiency ! Thanks for your suggestion !
