I've recently installed Ubuntu 12.04 on my computer. Now, every time I boot and when I shut down, my monitor goes blank and says "Input Signal Out of Range - Change Setting to 1920x1080 60Hz."
Once the computer gets to the login screen, it's okay again. This problem also happens when I try to open any 3d app.
My graphics card is NVIDIA GEforce 6150 SE. I tried updating the drivers, but it broke everything and I had to reinstall Ubuntu. Any help?
