I have the same problem after a fresh installation of Ubuntu 14.04.3 LTS. My laptop is Thinkpad W530, the graphics card is Nvidia K1000. I use two monitors and the the screen freezes from time to time when I running Chrome. I can move the mouse, but everything else freezes.
Ctrl+Alt+F1 does not work for me. But I can restart the machine with the magic key (Alt+PrtSc+REISUB) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1314871 Title: Graphics freeze, with applications continuing working properly To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1314871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
