Recently I installed Cairo-dock and changed the original Ubuntu theme. Then I uninstalled it, but the icons on the left side didn't get restored into its original look. Somewhere I found a command

sudo apt-get autoremove --purge  light-themes
sudo apt-get install light-themes

After running this command the theme didn't changed but it seems that the font of the original ubuntu changed a little. I want the theme of ubuntu as it was when i newly installed it. Moreover, the alt+tab and some other key combination not working normally. please help.

@Seth At least one of the answers may be helpful to others. And it has an upvoted. (I didn't just upvote it; it had one before.) So this doesn't even appear in the list of unanswered questions. I don't see a need to close this one. – Eliah Kagan Apr 5 '13 at 1:29
@EliahKagan The OP said the answer didn't work, so I see no reason not to close it since it didn't solve any problems. I upvoted it because it was a good answer, despite not solving the problem. – Seth Apr 5 '13 at 1:30
Since you upvoted it, you must have thought it would help someone else with this problem. Which means you think this question, with that answer, may help someone else with this problem. Which means the question is not too localized. – Eliah Kagan Apr 5 '13 at 1:31
@EliahKagan Maybe it will help someone else, but not with this problem that is the point. – Seth Apr 5 '13 at 1:46

OK, first things first: Don't input commands you don' t understand what they do.

sudo apt-get autoremove --purge light-themes sudo apt-get install light-themes

If you had Cairo dock installed and then removed it, the only thing that should've been removed was Cairo Dock. The themes and the icons have nothing to do with it.

So what you did was to remove the dependencies that Cairo dock installed and uninstall the themes along with them, which you shouldn't have done in the first place. And by the way, that command does not remove Cairo Dock.

Now, your question confuses me a lot. You removed Cairo, then changed the Theme back to Ambience (Ubuntu's default)? or what did you do?. Afterwards the theme didn't change (it wasn't the correct command to do that) and the Font looks weird (screenshot required).

Moreover your alt+tab issue must have been caused by something you *removed with the command.

To change Themes you have to install gnome-tweak-tool that'll change the themes, icons, fonts, etc.

To reset Unity settings use unity --reset.

Reinstall the Ubuntu Desktop package sudo apt-get install ubuntu-desktop

the font has been restored by running the command sudo apt-get install ubuntu-desktop but icons are still same – Harsh Dec 18 '12 at 13:55
Can you please add a screenshot. – Uri Herrera Dec 18 '12 at 15:37

The theme can be set in System Settings, under Appearance. For more detailed settings (including icons), you could try the application Unsettings. I have found this to be useful.

the appearance in system setting not helping. – Harsh Dec 17 '12 at 19:35
