    Ubuntu 12.04 freezes often in my acer aspire 4752 laptop

    I'm using ubuntu 12.04 for more than 6 months. But my ubuntu freezes way too often. My cursor not moving at all.

    Because of this problem I had to hard reboot my system often.

    So can anyone tell me whats wrong with my system?

    Here is my details

    Code:
    giri@ubuntu:~$ sudo uname -a
    Linux ubuntu 3.8.0-33-generic #48~precise1-Ubuntu SMP Thu Oct 24 16:28:06 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

    Code:
    giri@ubuntu:~$ lsb_release -a

    Check your autostart applications
    It is likely an application maybe causing that
    Or maybe some flawed setting.

    I use ubuntu 12.04 in my acer apire one D257 netbook. I face the same problem. But my ram is just 1GB. You have 5.6 GB , that should do well. Unity takes up lot of memory and firefox too. Why don't use fluxbox for a while. It is minimalistic and works very efficiently. Could you please tell us using what kind of application makes your distros get frozen?
    Code:
    sudo apt-get install fluxbox

    Go to a tty ALT+F1 or ALT+F2 and login and run top to see what's running in the background.

    I don't think it has anything to do with setting and autostart apps. Because this problem appears even in fresh ubuntu install.

    Next time you reboot look at the log files in /var/log - there may be something going on that it's causing the kernel to panic - such as a faulty video driver.

    I had a problem similar to this but my cursor moved.
    It turned out that gnome-screensaver was causing this
    I uninstalled it and replaced it with xscreensaver.


    At boot, you can try going to tty1 by pressing CTRL+ALT+F1 and then login
    Try this
    Code:
    watch -n1 "ps aux > ~/Desktop/ps.txt"
    The above command will list every process running on the system and output it to a text file by the name of ps.txt
    "watch -n1" will make sure this command runs every second

    You can analyze the ps.txt and see which program was running right before Ubuntu became non responsive
