I am a Linux/Ubuntu "noob" really so forgive me ahead of time. I I wanted to ask this question here also as I know there are some people on here who seem to be experts with some Linux distributions.
Anyway I started Dual Booting Ubuntu 13.04 with Windows 8 a couple days ago. The installation went smoothly and everything worked great. I was read up on some things about the Nvidia Drivers (was using my Intel 4000 Card first couple days) and seemed from everything I read, this command should work:
sudo apt-get install nvidia-current
everything seemed fine. I then did the update to 13.10. That seemed to go smoothly and it asked me to restart so I rebooted. On the reboot into Ubuntu that didn't go so smoothly. All I have is the desktop background. The Unity Launcher doesn't seem to load up. All I see is my desktop background and I can do crtl+alt+T to bring the terminal up but that seems to be it. Nothing else. I tried another reboot and the same thing.
I thought I would try to remove the nvidia packages and see if that helped. So I did
dpkg -l | grep nvidia-
so list the packages then removed them with
sudo apt-get purge <insert package name here>
that seemed to remove them. Rebooted and the same thing. Still only have the desktop background with no Unity Launcher or anything. anyone here have any advice about what the issue could be? I'm not sure what do about a recovery or anything like that. So if anyone has any advice to try or know what the issue could be that'd be great. A Google Search seems to lead that this was a Nvidia issue and to remove the packages. So I followed those instructions like I listed and nothing. So I am a little lost right now.
Thanks to all who help!
PS: my Windows 8 installation remains unaffected and is what I am using right now to type this and look for solutions.
