I am trying to use OpenGL on my laptop, a Dell Inspiron n5110 with Nvidia GeForce GT 525M. I managed to install my graphics card by using the following commands:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install nvidia-current
sudo apt-get install nvidia-settings
sudo reboot

But then I had some errors at my OpenGL program and since then I entered a lot of commands and managed to do something and now my resolution is fixed at 640X480. These are the commands I entered to fix my OpenGL problem:

sudo apt-get purge nvidia*
sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-   mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

And after running these commands I noticed that even though my graphics card was properly installed, in System settings->Details it did not appear. So I read this Nvidia Graphics shown as unknown and entered the following commands and that's when my resolution got stuck at 640X480

sudo apt-get install mesa-utils
sudo reboot
sudo nvidia-xconfig

So I guess that what I am trying to ask is how can I revert my laptop to it's previous state

Also here is the output of the lspci | grep VGA command:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 525M] (rev a1)

Try first to disable the ppa and then install nvidia-current from ubuntu archives:

sudo add-apt-repository --remove ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current
sudo apt-get install nvidia-settings

Nothing has changed. The driver was installed before running the commands you told me about. I thought that the mesa-utils package was the problem so before you answered I uninstalled it from the Synaptic Package Manager –  user1956190 Mar 10 at 20:38
