Logged in as that user, open a terminal and
users sys lp floppy dialout audio video cdrom plugdev power usbfs netdev scanner vboxusers cvs
You should see pretty much the above (except
vboxusers and cvs -- you won't have those unless you've installed VirtualBox and have set up CVS).
When you added the user account (with the Slackware utility useradd
) there is a question about groups:
User ID ('UID') [ defaults to next available ]:
Initial group [ users ]:
Additional UNIX groups:
Users can belong to additional UNIX groups on the system.
For local users using graphical desktop login managers such
as XDM/KDM, users may need to be members of additional groups
to access the full functionality of removable media devices.
* Security implications *
Please be aware that by adding users to additional groups may
potentially give access to the removable media of other users.
If you are creating a new user for remote shell access only,
users do not need to belong to any additional groups as standard,
so you may press ENTER at the next prompt.
Press ENTER to continue without adding any additional groups
Or press the UP arrow key to add/select/edit additional groups < I did press the key here >
: audio cdrom floppy plugdev video power netdev lp scanner
If you did not do that, you can add those groups to the user account with the usermod
usermod -a -G audio,cdrom,floppy,plugdev,video,power,netdev,lp,scanner userid
It's *critical* that you use the -a
options as shown and that the group names are separated by a comma (no
white space); "userid" is the user log in. If these groups did not show up when you used the groups
utility as above, you should simply do all of them as shown here.
Wouldn't hurt to read the manual page for usermod
Hope this helps some.
