Run the command in the terminal as suggested to start with. If there are any more errors copy and paste them in code tags using the # symbol on the reply box tool bar.
sudo apt-get install -f

I did this command and then ran sudo apt-get update, it updated my ubuntu, but now after i restarted my launchpad and tasbar are not showing up, so i am unable to to use it.
My terminal also runs only once i.e. when i press ctrl+alt+T it works, when i close it once it too dont start up.
I can only see wallpaper in the whole screen nothing else.
I tried pressing windows key to get back launchpad but was of no use.
( Now i am again using windows 7 to reply to this thread, please help me asap to get rid of windows 7 )

i reinstalled using the live disc, all software packages i installed last day spending 8 hours were gone, brightness control and other things still dont work. I think i am done with ubuntu, do you think 13.04 would be any different.
I think i will wait till ubuntu release something more stable and better. ubuntu 10.1 was the last best thing i used

You may want to post regarding your driver . I am not an ATI user and don't what driver would best suit your card. Consider Xubuntu because it is less demanding or install the gnome fallback session.


sudo apt-get-install gnome-session-fallback
Select during login
