PC very slow with any graphics acceleration

Question

I think I don't have the correct driver for my video card which is integrated (the pc is mainly used for office work). I'm using Kubuntu 14.04.1 Each time I start any site with heavy graphics or where it requires acceleration (youtube, google maps street view, etc.) the pc is slowed to a halt nearly..

I don't have xorg.conf in /etc/X11/ and I don't know what to do.

I don't think you have a driver issue. Your problem is that you're trying to run Kubuntu, which has the highest sytems requirements of any *buntu edition, on a computer that has only an Intel Atom processor. For a normal performance on a computer with an Intel Atom processor, you should use a more lightweight *buntu edition like Xubuntu 32-bit or Lubuntu 32-bit. Xubuntu 32-bit should run fine on your computer. Lubuntu 32-bit is even more lightweight, similar in its systems requirements to Windows XP.

If you don't mind waiting until the official Ubuntu MATE 15.04 is released this April, then I will switch gears and recommend Ubuntu MATE 15.04 instead of Xubuntu because it has better default apps for what you are doing including Firefox, Thunderbird, LibreOffice, VLC, Rhythmbox and the Ubuntu Software Center. Lubuntu 15.04, Xubuntu 15.04 and Ubuntu MATE 15.04 all have similar minimum systems requirements.
