Presently Installed Ubuntu 12.04 LTS as stand alone through USB overwriting older linux versions option. Previously installed as dual with Windows XP. Then for about 7 times as stand alone with custom partitions. Used all space for partitions. Missing swap problem occurred. Once Nvidia driver update showed up. When updated screen went reso wrong. So I always avoid nvidia driver update. Lastly allowed a lot of free space to avoid bad sectors and installation successful. This time the missing swap area problem is not arising.
But always when boot for first time, Both mouse and keyboard inactive in Login screen. I have to switch off directly and reboot.
Always for the second time - Ubuntu leads to GNU GRUB recovery option screen. When I choose (recovery option) everything properly recovers to a working Login screen with activated mouse and keyboard.
I am very new to Linux and Ubuntu, but can follow instructions both terminal and desktop based. I am planning for a big UBUNTU awareness program in my area and need help to make myself professional. Please do Help.
