    Screen flickers and the computer's not responding


    This issue is driving me crazy:
    It happened at Ubuntu 12.04 (LTS), and now in Linux Mint 13 (Maya) MATE.

    Every 5 minutes or so, usually when I click my mouse (right, left and middle click), the screen flickers and freezes (as the title suggests).
    I can still move my mouse and click on things, but nothing is responding. not from clicks nor from keyboard hotkeys.
    Also the cursor symbol freezes (won't change from arrow to IBeam etc.)

    And if I wait long enough the cursor changes to random things
    The only way for me to get the computer responding back again is hard-restart.

    I should note that when I experienced it on Ubuntu 12.04LTS I downgraded to Ubuntu 11.10 and everything was fine there.
    I'm not sure what to do, can you help me?

    Have you attempted to update your system yet, since installing? It is possible that there is a bug related to your hardware that was fixed by a kernel or other package update. See the Update Manager application.

    Yep. I've updated everything.

    Well, Mint and Ubuntu are pretty much the same thing with different colors and whatnot. I suggest you try another distro or stick with Ubuntu 11.10. It could be that your video card doesn't like the latest version of Xorg or something.

    Okay. How about logs, have you check them? Specifically, the syslog and Xorg.0.log might be worth a look.

    I don't know what to check and where it is.

    Use the terminal to issue these commands.
    Code:
    sudo cat /var/log/Xorg.0.log
    err, I don't have syslog, so I don't know the command for that. Unless he meant:
    Code:
    tail /var/log/messages
    or
    Code:
    dmesg

    yep, those are both exactly what I meant. i just wasn't sure of the location of the syslog in Ubuntu.
