I am using Dell Latitude E6510 laptop with Ubuntu 12.10 running on it.
It has Nvidia GT218 NVS 3100M.
I am using
My problem is that my laptop was just working fine.
However, it was having very high temperatures (+70 degrees normally).
So I read about some blogs, where someone advised to install
nvidia-bumblebee. So I installed these 2 softwares.
Jupiter, I was unable to change the screen resolution.
Neither it was able to detect the external monitor.
Though my laptop was super-cool. It was running at 50-60 degrees.
But since this being useless, as I always use an external monitor, I uninstalled both the softwares. Also I realised that I don't have
Optimus support on my laptop.
Now I am unable to go back to the initial settings. I am stuck up at 800 x 600 resolution. When I try to run nvidia-settings I get an error message saying:
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server
I tried to run
nvidia-xconfig, but it didn't work. The error remains the same.
I tried to find help on internet on lot of forums. I tried to re-install the nvidia packages, but it didn't work. Also I tried to use nouveau driver, and then again install nvidia drivers, the problem is still the same.
Could someone please let me know how do I solve this?
