I buy this Lenovo ThinkPad T400 laptop on last month and within one month I installed Ubuntu 10.10 with the previously running windows 7. Both are works but when I boot system with Ubuntu 10.10 OS, I found that it is slightly laggy. Mouse cursor has been moved for just few seconds and speed of this system is being also bit slow compared with the other windows 7 system. What should I do that works to fix this complex issue? Need any meaningful information about this issue.
