To save time to help others I standardized this first reply.
Some forum members don't know they are supposed to inform themselves before posting.
Well, please try to follow this procedure: First read Quickly get help
> Terminal > Opening a Thread > Problems (Hardware, Sound
, Grub, Partitioning, Network) > Links [solved problems]
Search for a solution, both in the forum and on the internet.
Your cooperation would be appreciated. Thanks.
I'm sure after having posted relevant details you will get personal help.
