DVD will not read on user, Slackware on a Laptop
 

I recently bought a laptop, and installed 12.2 on it root will read the instruction manual, but I cannot get anything other than a very long warning message on the user. I suspect that I have not include the user in the right group to have access to the CD/DVD drive, can anyone advise me please?

I have some other problems with acpi and two of the USB ports having <access denied> but I'll deal withmy problems one at a time.

Check the file /etc/group

Add your user name to cdrom, plugdev (for usb devices), power (for shutdown/reboot).

some lines from my /etc/group for your reference;

cdrom:x:19:root,kite
plugdev:x:83:root,kite
power:x:84:kite
audio:x:17:root,kite

And do not forget to logout and login to take effect.

You need to add the user to the group "cdrom".

usermod -g cdrom YOURUSER

Having gone back through my installation notes for previous versions of Slackware I have found that I needed to add my users to the groups cdrom which I had done and plugdev which I hadn't, so I've solved that problem, thanks to all.

No, Don't do that!
It'll change your initial group, which is a bad idea

To add a user to a group use, gpasswd (Yes, I know, the command name doesn't quite fit the function in this case, but its the right command for the job)

e.g.

where <userid> is your userid. and in this case the group is cdrom.
