Guys, I installed nvidia driver from here [http://www.nvidia.com/object/linux-d...3-driver.html]
to my ubuntu 10.04.3. Installation ran successfully but until now I cannot log out my laptop. When I logged out, it dimmed several times and finally gone black screen. It seemed there was a dialogue telling an error (not readable) in the screen. I had to push the power button to shut my notebook down. My laptop is Asus A43S, Core i5 2.3 GHz, 2 GB Ram, and Nvidia Geforce 540M. Is there any solution for this? I had reinstalled the nvidia driver and GDM but it didn't work. Any reply is appreciated. Thanks in advance.
