Hello,
Could you post the groups to which your user belongs to? Use the following command:
Code:
cat /etc/group | grep `username`
Change `username` to the actual login of your user.
I would suggest to add the user to these groups if he/she doesn't yet belong to it.
audio
cdrom
plugdev
power
video
Use the following command:
Code:
gpasswd -a `username` `group`
Replace `group` with the above-mentioned groups.
