Hi Martin, for me it is: 3.5.0-18-generic
Seeing this on 2 machines actually. DE doesn't matter. (Tested Unity and Gnome-Shell) Both machines are 64 bit versions. First: Nvidia 8600m using nvidia's driver Second: Intel Sandy bridge (i3 with HD3000 gfx build-in) For me it is not driver/DE related but Xserver itself. I am ready for running any test needed. -- 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.
