I get complete freezes running Ubuntu 12.04 64 bit on an Intel Ivy Bridge machine with integrated graphics.
For me, one way to induce a freeze is to randomly drag the map in Google Maps, both in Firefox and Chromium. The freeze will occur within a few seconds of dragging. This happens in Unity 3D as well as Gnome Shell, Unity 2D seems to be stable. I suppose this is a 3D-only issue. When running Unity 3D from a live USB stick I can not reproduce any complete freezes with the map-dragging method, but Firefox freezes for a short time every few seconds. Sometimes the window turns dark. However, the mouse is movable the whole time. When I make a fresh install as suggested by Hein (#51) the freezes are back, which is why I assume that the problem is not introduced by an update. Many of you seem to use mobile or integrated graphics. Might this be a problem with shared memory? -- 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 64bit 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
