My Sony's notebook has double system of Windows 7 and Linux Ubuntu in finally. It take me much time to partition the the 500 GB disk, set the three section use by Win 7 and the others for the Ubuntu, swap disk and data store. In yesterday, I made a mistake in change the 80 GB section to swap that make system overhead. Today I reset the hard disk by win 7's application, and start to install Linux Ubuntu in the new partition. When the time after install, I use the terminal to key some instruction but don't have enough privilege to execute. Therefore I found the sudoers.txt and attempt to overwrite the administrate member by add my name and privilege, but the text property is read-only so I am fault to overwrite final. However, shutdown the system and restart it after I take a nap, the sudo instruction become ordinary situation. After all, I update of Linux Ubuntu and download series of software that I use to in win 7,and I press the shut down button to close system. The amazing things happen is nothing happen at all, I think the function of shut down may damage, Hope it can recover by the next time I open it.
