Success Fixing Audio Driver Broke Unity

[ProntoAnthony]

I've been scouring this forum for ideas and suggestions. The latest one being https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules

I was trying to follow the instructions and ended up removing several repository sources in the Other Software Category. Unfortunately I cannot tell you which ones of my repositories I removed. Synaptic Package Manager | File | History doesn't list them either.

However now when I log into Unity I never get to anything other than my wallpaper background. I can do a Control-T and bring terminal up. So I logged out and tried Unity 2D.

When I login to Unity 2D it comes up fine, but most importantly my Audio Driver is found (I see it in Sound Settings) and the PC now will play audio that I can hear!

The audio driver remains in Gnome, too.

So how do I fix my system to re-install Unity 3D? When I go into Synaptic Package Manager and do a Quick Filter on Unity and then right-click on unity, the option for Mark For Reinstallation is greyed out.

In fact the Mark For Reinstallation is greyed out of all packages.

In terminal I do a:

Unity --replace

The result is shows a Compiz bug:

I'm out of ideas at the moment. Any help would be appreciated.

are you sure that in ccsm unity box checked ?

have you tried

unity --reset

if above things are not worked then try to remove it with purge and install again.

sudo apt-get remove --purge <pkg name>

then install it again .

all the best,

Raja,

Thanks, but remember, I can't seem to install anything. Here is a record of what I tried:

anthony@anthony-Dimension-E521:~$ sudo apt-get remove --purge unity

I'm going to get my laptop and see about adding the repositories it has that my desktop does not. That should do it.

[ProntoAnthony]

Nothing like some heart-stopping excitement in the morning!

I'll spare the details, but I managed to copy over the /etc/apt/sources.list file to my desktop.

I then entered into terminal:

apt-get update
apt-get upgrade

then I went into synaptic package manager just to check that I could add packages from the program utility again and installed unity.

Then the moment of truth: I logged out of Unity 2D and tried logging into Unity.

No change. It wouldn't come up! So I went into Unity 2D and then went into CompizConfig Manager and noticed the Unity Plug-in wasn't checked. Of course not, I thought. I just loaded it.

Once I checked it I am able to log in to Unity, plus I have my sound.

Yippee!

yeah! again ccsm in the action.

Enjoy The Ubuntu.
