    I just installed Ubuntu 13.04 64. The HD was clean and nothing was on it when I did the install. I have Windows 7 installed on another drive and it runs smooth. The problem I'm having is it is running very slow, freezing on me and taking a few minutes to load. I had 12.04 on the same comp and it ran fine.

    Memory -2.0 GiB

    Processor - AMD Athlon 64 Processor 3700+

    Disk - 115.9 GB

    Graphics - gforce 7900gt 256bit nvidia

    You may need to activate property drivers (probably for the graphics card) install Additional Drivers from Ubuntu software center and then activate the recommended driver.

    64 bit - Ubuntu running slow on my good machine!

    Its fixed now :)

    I just installed Ubuntu on my PC. I lag a lot. My pc runs all other OS' at high speed, but ubuntu lags like hell. It worked on my old laptop.

    My Specs:

    • XFX AMD Radeon HD 7870 Black Edition

    • AMD A8-3800 APU

    • 2x4 GB 1333 MHz Ram

    • 1TB Harddrive

    I installed the latest version of Ubuntu. 13.04 I believe.

    I run Windows and other linux distros really fast, so why does Ubuntu lag?

    First, make sure you have the drivers needed, so open a terminal, and run this:

    sudo apt-get purge fglrx*
    sudo apt-get install fglrx
    sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
    sudo aticonfig --initial
    

    Then reboot.

    If ubuntu is still slow, you might want to change your desktop environment to something like LXDE, XFCE, KDE, or GNOME (though GNOME under ubuntu can be slower than unity, partly due to the excessive patching made by canonical).
