I recently installed ubuntu on a Lenovo Y500 with a Nvidia geforce chip. startx does not work.
First I was told that module nvidia did not exist, so I installed nvidia-current, which eliminated that issue. My X log file says my driver ought to be supporting my gpu. However, the file also returns the following warnings:
Falling back to old probe method for vesa Falling back to old probe method for modesetting Falling back to old probe method for fbdev
Failed to initialize the NVIDIA GPU at PCI:1:0:0. Failing initialization o x screen 0
So for some reason my GPU isn't initializing, even though my driver should be working with it.
Running startx reveals:
NVIDIA: could not open the device file /dev/nvidia0 (Input/Output error).
But that doesn't get recorded in the log file, for some reason. In dev, I can find the nvidia0 file, but when I nano it it's empty. I suspect this is because of the file type, not its contents and I'm just being stupid, but I thought it might be relevant. Nothing else I can think of reveals anything about this file.
So I thought, maybe it's a permissions issue. Sudo startx returned the same results. Logging in as root changes nothing.
I am now stuck. I can come up with nothing else. Help me, askubuntu, you're my only hope!
