My Ubuntu 12.04 only shows up black screen when starting up some days ago suddenly. Since I can desktop through recovery mode (resume in recovery mode, and the resolution is wrong), I believe there's something wrong with my video card driver. So I go to nvidia's website, download the driver NVIDIA-Linux-x86-310.44.run, and installed it successfully.
Now, while I can get the following output with
lspci | grep -i nvidia
01:00.0 VGA compatible controller: NVIDIA Corporation GT215 [GeForce GT 335M] (rev a2)
the driver seems not to be activated.
When I start up NVIDIA X Server settings, it shows up a message box saying
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run
nvidia-xconfigas root), and restart the X server.
But I do run xnvidia-config successfully, and also reboot the system.
What's more, the "Additional Drivers" is blank, saying
No proprietary drivers are in use on this system
Could anybody give some hints on how to deal with this problem? Thanks a lot!
