(update to 14.04) unity is not loading after I login to the admin profile after upgrade [duplicate]
After upgrading to 14.04 and after the final reboot, I logged in the admin account but unity won't start, I have only the 14.04 background.
No shortcuts work. I can login and use the guest and other accounts on the machine.
I think I might have opted to keep one of the settings that I was asked to select during the upgrade to 14.04.
What other info can I provide?
My chipset is Intel GM45 mobile.
Why does unity on the other accounts (guest, etc) login and work normally?
I have only been using ubuntu since 13.04, so im not that familiar with it. My setup is dual boot with windows 7 on a laptop. Can someone help?
Solution 1:
I had a similar problem, I solved it by switching in terminal (CTRL+ALT+F1) then removing the configuration file ~/.config/dconf/user like this :
(! this action will remove your gnome 3 settings !)
sudo service lightdm stop
rm ~/.config/dconf/user
sudo service lightdm start
Solution 2:
I had the same problem. The only way I could solve it was this:
Press
ctrl + alt + F1
to access a terminal. You have to log in with your user. Then run
sudo apt-get install unity-tweak-tool
and finally
unity-tweak-tool --reset-unity
If you get errors try running it again. You should then be back at the welcome screen. Log in and unity should be there, albeit without any custom settings you may have had.
Solution 3:
I sometimes had a similar issue in Saucy and Raring. I was able to fix that with re-enabling the Unity plugin in Comppiz Config Settings Manager. Using CTRL-ALT-T you should be able to open a terminal. There you can install the Compiz Configuration Settings Manager
sudo apt-get install compizconfig-settings-manager
Then you can start it using
ccsm
where you should be able to find a plugin named Unity. Click the checkbox to enable it and Dash with the sidebar should reappear.
