I've been an XP user forever and I still am. Yesterday wanted to try Ubuntu I installed it and its very very slow on my computer. Here's my computer specs intel celeron(R) 2.40 GHz 1 gb of memory . Did I do something wrong because I heard Ubuntu is really fast. When I look in system monitor it says the the CPU is constantly at 100 %.



It's because Ubuntu is using your CPU (which barely makes the cut) to handle GPU code for the Unity interface. Use Additional Drivers (jockey-gtk or Software Sources > Additional Drivers tab) to see if there are graphics drivers available for your system. If not, you may want to consider buying a better computer. Or, since those are very minimal specs for Ubuntu, you may want to try Lubuntu, Xubuntu, or even Kubuntu (which is also somewhat cumbersome), all official variants of Ubuntu, or even a whole different distro; there are plenty out there.

  • I don't think the conclusion it is Unity is warranted given the information presented. – msw Aug 12 '13 at 20:03
  • As searchfgold6789 suggested, use an Ubuntu derivative that will not require more from your graphics card and cpu. Lubuntu or Xubuntu are quite zippy; you'll like them, and you will still have access to all of the community support and software you would get to use if you had Ubuntu installed. – PJ Singh Aug 12 '13 at 20:18

Press Ctrl-Alt-T to open a terminal window, and run the command top to see what might be hitting your CPU so hard. Something is probably misbehaving and this is the first step to finding out what it might be.

  • Seems to be 1015 root what is that – Miguel Aug 12 '13 at 20:44
  • The rightmost column will tell you the name of the process which will allow us to make a more educated guess at what the problem is. – msw Aug 12 '13 at 22:19
