I have to agree with yorgasor #20. There are two different bugs here. I happened to be affected by both. I could reproduce the google-earth bug by running google-earth and zooming into something. The X server would lock, but I could still move the mouse. Using the "sudo intel_reg_write 0x2120 '0x1206800'" fixes that bug for me, I can zoom fine with google- earth and the X server does not lock up anymore.
But then I have also this other problem, that approximately every six hours the whole machine freezes. The keyboard doesn't respond, the mouse doesn't move, SysRq doesn't respond, and after a while I can hear the hard drive doesn't spin anymore, that is, the machine becomes very quiet. No logs get produced. I am at odds here. Downgrading the kernel doesn't fix it. Upgrading the kernel doesn't fix it. Downgrading the X server doesn't fix it. It all started after upgrading to Ubuntu Precise, but I am starting to weight the odds that this might be a hardware problem rather than a software problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
