You have been subscribed to a public bug: When running 12.04.2 with the nouveau driver, the system (X) does not recover after suspend and the system eventually freezes.
The machine starts to recover from suspend, however, the screen remains black, or in one case, became a weird black and white zig-zag pattern with a mouse pointer visible. At this point, the machine churns for a bit then completely freezes, requiring a power-cycle to return to a working state. Installing the nVidia proprietary driver resolves this issue: ii nvidia-common 1:0.2.44.2 Find obsolete NVIDIA drivers ii nvidia-current-updates 304.64-0ubuntu0.2 NVIDIA binary Xorg driver, kernel module and VDPAU library Using that as a workaround, I am able to suspend and resume this machine.
