I cannot see the administrator panel in Control Centre

[alexyia]

I am running MATE Desktop Environment 1.16.2 on Rock64. The device was given to me to set up a monitoring display but I am not sure if I have an admin account. I have logged in with the creds rock64 [username] and rock64 [password].

When I go to the Control Centre I only see Hardware, Internet and Network, Look and Feel and Personal under Groups. I saw in screenshots there should be an Administrator panel available. I can only assume the account I am logged in with has limited access.

I have tried booting into GRUB by holding in ESC and then again SHIFT on start up as read on a few posts. Later I read I need to hold down shift on a grey splashscreen which I don't see so I tried the login screen but that didn't work. I've tried various root combinations suggested such as debian debian but none work.

I am not really accustomed to Linux so this is all new to me and this is the first time I've even seen a Pine. 

My goal is to change the power settings so that it never goes into sleep mode but now I also want to get the root account so I at least know what it is.  

Any help will be greatly appreciated.

This won't work at all, as there is no grub bootloader. I don't actually know of any single-board computer that has grub on it.

To access the root account, you'll need to set a password for it, which will unlock the account. The rock64 user account is a admin level account, so you can do a "sudo passwd root" at a terminal prompt (hint: Applications -> System Tools -> MATE Terminal) and type in a password for the root user.

As far as power settings, they should be in the System -> Administration or System -> Preferences section, pretty sure the applet you're after is just called "Power"...

I see. Thanks for the guidance. I was able to change the root password! Unfortunately I still can't see the Administration option under System so I can't access any of the admin settings that I need to change. I logged in as root hoping it would show but still not. Any ideas? I only see Hardware, Internet & Hardware, Look & Feel and Personal none of which contain power settings.
