My problem is that when I was trying to install Nvidia drivers (some 301 version) on Ubuntu 13.04, it evokes a message a:
Ubuntu is running on low graphics.
After the installation(I am repenting that installation a lot :(). Now, whenever I reboot my laptop it show only command line version of Ubuntu 13.04.Though I could have reinstall the Ubuntu using usb-stick, but it could cost me loss of important data which is stored in home/username/ folder. I tried to copy this folder using live Ubuntu through usb-stick, but it is showing that you don't have permissions to copy that. Now, my problem could have multiple solutions such as-
I can reinstall Nvidia or integrated Intel graphics driver so that I can continue with my previous installation and data.
I can copy the data to an external harddisk through commands (which I don't know) and reinstall Ubuntu(which I know :))
I can copy the data though live Ubuntu run through usb-stick to external hard disk. problem is I tried many commands on this forum with similar problems but none had worked yet.
Your help will be appreciated.
