I'm sure that this has been asked before. I'm not completely new to Ubuntu, I started with 9.04, but I stopped using it for a long time, and am currently Dual-Booting 11.10 alongside Windows 7 on my laptop.
I wanted to enable the Compiz effects, but Ubuntu was not recognizing my graphics card (nVidia GeForce 525M) so I thought maybe updating the driver would help. I Ctrl+Alt+F1 entered TTY mode, and I did the following:
sudo service lightdm stop cd ~/Downloads sudo sh ./NVIDIA-Linux-x86_64-290.10.run
and then I went through the setup for the nVidia driver. It said it installed correctly, so I restarted my laptop through Ctrl+Alt+Delete, and then when I went to load Ubuntu, it loaded in TTY mode.
I can't seem to figure out how to get back to the User Interface for Ubuntu.
Anyone who could help me out, it would be greatly appreciated.
