I did a clean install of Ubuntu 12.04 about three hours ago. Now I've been installing all the programs I use, etc...



However, I seem to be having a problem with a VERY laggy dash, to the point where it's almost completely unresponsive. When I open the dash and search for a program like Firefox, as I type Firefox the letters come about a second after I push the key, and the whole system starts to freeze up. When I try to highlight a program I recently used the mouse literally skips across the screen as if the screen cant keep up with it. Is anyone else having similar problems? Also, I know this is a longshot, but could any programs I have installed slow down my system? I'd love to get this sorted out, because it's a pain to have such an unresponsive menu, and I really don't want to use Gnome 3.4.



The problem is it doesn't "know" what my graphics driver is. Which is clearly a problem, how can I fix this?



enter image description here



According to Ubuntu 11.10 I had Intel Ironlake Mobile Graphics, according to this I have nothing. (Didn't have this problem in Ubuntu 11.10)



System Info:




  • Intel Core i3 CPU M370 2.40GHZ

  • 3GB of installed ram

  • 64 bit Ubuntu

  • Intel Ironlake Mobile Graphics



Anything else needed?

I have encountered similar problem - overall system performance was superb, but the moment i've hit the dash button, a major lagging started.



After installing ccsm i determined that in my case problem was connected to blur in dash. Surprisingly the solution for me was to activate KDE Compatibility -> Blur support in CCSM. You can also try to disable blur or change it to static (ubuntu unity plugin -> experimental -> dash blur).



To install CompizConfig Setting Manager type/copy into terminal:



sudo apt-get install compizconfig-settings-manager


Please, be very careful with this tool, it can really break your system.



I hope this will help with your problem.
Good luck.
