I have an HP notebook with an NVIDIA GeForce 7150M graphics card, and have hardy installed on it. I downloaded the driver from the NVIDIA website, and followed the instructions to install it. It installed perfected, and without errors. It was working perfectly, but then I installed some Ubuntu updates and restarted the comp, and thats when it stopped working. I Reinstalled the driver, and it worked again until I restarted my computer. Does anyone know what the problem is?
