I can confirm this also. I first suspected faulty hardware, but the same error occurs with two differenr motherboards.
Intel Z77 chipset (both motherboards) and Ivy Bridge i7-3770. I also do not use any external graphics card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999910 Title: 12.04 64 bit System freezes (mouse, keyboard) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/999910/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
