Hi guys,

I recently install XFCE then removed GNOME. But in XFCE I got the problem of this h/w permissions so I thought restoring GNOME would help ....but no.

The funny problem now is I am unable write CDs/DVDs via my user account and not even play audio CDs. Also, I am unable to scan using my user account.

All of the above tasks are found to be working via root account.

I have also tried SELinux in Permissive mode, huh no use.

HELP!!!! HELP!!!! HELP!!!!

change the ownership (chown),

or create a new user (adduser)

Is your user added to necessary groups such as cdrw, disk, usb, audio and such?

Edit: Also check if thunar-volman is installed..

QM: I have removed XFCE.

Code:
$ id

uid=500(secret) gid=500(secret) groups=0(root),500(secret) context=system_u:system_r:unconfined_t:s0

Yeah I changed it for sudo to give root group sudo permissions without password
