I am planning to install Ubuntu on my old laptop - IBM ThinkPad T41. The laptop has 1 GB RAM, 50 GB hard disk, 1.6-GHz Pentium M processor and 32MB ATI Mobility Radeon 9000 graphics card. I would prefer to install and run Ubuntu with Unity 2D on this system, but would also want my system to be fast and responsive.
My question is this: will the Unity 2D interface run fast on this system, or should I install Xubuntu or Lubuntu instead?
Thanks.
