After X crashes, if I try to restart it, frequently the screen locks up entirely. I've discovered more information in the Xorg.1.log (attached).
Here is an extract: [ 40345.063] (II) NVIDIA(0): NVIDIA GPU GeForce GTX 560 Ti (GF114) at PCI:1:0:0 (GPU-0) [ 40345.063] (--) NVIDIA(0): Memory: 1048576 kBytes [ 40345.063] (--) NVIDIA(0): VideoBIOS: 70.24.21.00.02 [ 40345.063] (II) NVIDIA(0): Detected PCI Express Link width: 16X [ 40345.067] (EE) NVIDIA(GPU-0): EVO Push buffer channel allocation failed [ 40345.067] (EE) *** Aborting *** [ 40345.067] (EE) NVIDIA(GPU-0): Failed to allocate EVO core DMA push buffer [ 40345.067] (EE) *** Aborting *** [ 40345.067] (EE) NVIDIA(0): Failing initialization of X screen 0 [ 40345.070] (II) UnloadModule: "nvidia" [ 40345.071] (II) UnloadSubModule: "shadow" [ 40345.071] (II) UnloadSubModule: "wfb" [ 40345.071] (II) UnloadSubModule: "fb" [ 40345.071] (EE) Screen(s) found, but none have a usable configuration.
