LightDM does not appear after installing a driver from Additional Drivers

http://askubuntu.com – I simply was looking at the default drivers it gave me (under System Settings->Additional Drivers) and I selected version 96 and activated it. After it installed it asked me to restart, and I did. Now it will not boot back up; the problem is that LightDM will not come up. I am new to Ubuntu, and I need to know a command to shut down all drivers or something. (HowTos)

Stories similar to LightDM does not appear after installing a driver from Additional Drivers

OK so I just got Ubuntu the other month or so. I'm running the 11.04 version currently and trying to install drivers for a Nvidia graphics card (it's my brother's computer and he currently cannot find the number of the card right now). I read that, to install the proper drivers for gaming, I would need to go into "Additional Drivers" and choose them myself.

So I updated my graphic drivers using the additional drivers option and restarted my computer upon completion.

I updated my drivers using the additional drivers tab

my video is an AMD Radeon HD 7640G

after changing the driver now when when ever i restart / reboot

all i get is the command line prompt

how do i revert back to the original drivers supplied by ubuntu

the proprietary drivers don't seem to work

Hey!

I can't see any additional drivers on the Software Sources -> Additional Drivers tab. It is all empty. Does this just simply mean that there are no additional drivers available for my computer?

And, what are the commands to find out if Ubuntu even detects my hardware? I have a wireless card and ATI Radeon HD 3200 graphics card.

Hello, I've just installed Ubuntu 11.04 (64-bit). After installation I selected "NVIDIA accelerated graphics driver (version current) [Recommended] from the Additional Drivers dialog box and let it download and install.

I've dual-boot my Ubuntu 12.10 and I had my default 12.04 LTS problem, it is the Graphics. Usually I use the "Additional Drivers" to check out my "hidden" Graphics card. But after I replace the Precise with Quantal, I didn't found my "Additional Drivers" in System Settings!! I already download from Ubuntu Software Center, and after it finish I still can't find it.

Has anyone else noticed that the Graphics details in System Settings -> Details is not available, while its easily available from the Additional Drivers window?

As far as I know, the System Settings -> Details application is controlled by Gnome. I haven't checked this screen with open source drivers enabled, but I assume it works for them.

Installed Ubuntu in my MacBook. worked fine at first. installed additional drivers and updated. restarted. now all I get is a command line. can't boot back into the USB stick I originally used to instal Ubuntu. help?
