Details on the problem from Nvidia:
"sometimes chipsets lose their AGP configuration during suspend, and may cause corruption on the bus upon resume. The AGP driver is required to save and restore relevant register state on such systems; NVIDIA's NvAGP is notified of power management events and ensures its configuration is kept intact across suspend/resume cycles."
I fixed the problem, however the credits are not due to me. Although my pc is not a laptop the problem is the same. It is as a result of corruption see: [http:// us.download. nvidia. com/XFree86/ Linux-x86/ 1.0-9755/ README/ appendix- q.htm]l
Instructions From: [https:/ /help.ubuntu. com/community/ NvidiaLaptopBin aryDriverSuspen d ]
This must be added in xorg.conf:
