I have a Dell XPS M1330 with Intel Dual core. Preloaded windows 7 was very slow on it so I installed Ubuntu 12.04 on it but I think that my system is not capable to handle requirements of Ubuntu as it is very slow in response. Can someone suggest me a lite GUI Linux version. I plan to watch movies on this system so a lite version that is comparable with avi or flash player would suffice. Thanks a lot.
