This is my first time installing Linux on a computer, though I have been using Unix and Linux systems for years. I managed to install Lubuntu 12.04 (could not get 12.10 to boot from hard disk). That was an ordeal in itself due to the lack of the nv driver. Everthing works execpt for sleep or hibernate. I cannot get the computer to sleep or hibernate either manually or by shutting the lid. Sometimes the screen will blank but with the backlight still on. Disk keeps running. I have tried out numerous suggestion I found on the web to no avail. I would be happy if either sleep or hibernate works. Help will be greatly appreciated. Thanks.
