I am a very basic Ubuntu user. Everytime I am trying the terminal, I receive the following question and I do not know how to answer: Do you have full superuser (root) permissions? I want to configure the TV at home to send video via HDMI port. When I write "get-edid", the question appears. y, yes or -y do not work. I am the root and know the password.

I would like to learn how to say "yes" on Ubuntu?

Thank you in advance.

  • Please edit your question and explain what you do when this happens and the message itself. –  Jan 12 '13 at 18:25
  • Thanks but the only information I can give is this much. What is nouveau driver? Or are you just speaking French? – Miraç Gül Jan 12 '13 at 18:35
  • But I have a RADEON HD 4200. – Miraç Gül Jan 12 '13 at 18:41
  • You should try sudo get-edid. – Eric Carvalho Jan 12 '13 at 18:41
  • @EricCarvalho already on it and yes it does need sudo (took a bit of time installing it ;)) – Rinzwind Jan 12 '13 at 18:44
  • :) thank you. Now I am able to see the EDID information. But still wonder how to say yes. – Miraç Gül Jan 12 '13 at 18:45
  • It is a question you can not answer when it shows: it is a comment echo'd to your screen as a hint to the problem it sees: get-edid can not access a command. The answer to the question is no and the action to get rid of the question is to use sudo in front of the command (the program then sees that the answer is yes and continues ;) ) – Rinzwind Jan 12 '13 at 18:48
  • How can I close the question? Do I add [DONE] to the subject line? – Miraç Gül Jan 12 '13 at 18:51

    No need. Accepting the question will make it disappear from the frontpage. The website will once every so often put questions with no answer back to the frontpage (and will ignore accepted ones) – Rinzwind Jan 12 '13 at 18:54

You need sudo in front of the command get-edid. You are accessing hardware so it will need to issue commands that a normal user can not use.

This

get-edid | parse-edid

will give ...

mmap /dev/zero: Operation not permitted
get-edid: error initialising realmode interface
get-edid: do you have full superuser (root) permissions?

because the mmap /dev/zero needs root permissions.

sudo get-edid | parse-edid

will show something similar to...

Performing real mode VBE call
Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0
Function supported
Call successful

etc.
