As for K3B permissions, I think you can just go to "Settings>Setup System Permissions" and enable the "cdrom" group as the burning group. You can make other changes there too, but I don't think I had to.

The cdrom group exists by default in Slackware -- add your user to it (edit /etc/group as root and put your username [without the quotes] after the "cdrom" group). For example, mine looks something like this (edited to change username):
You should do the same with the plugdev, audio and video groups if you haven't already. Add the cdrom group as the burning group in K3B and restart your computer. Then try burning again. Hopefully it will work better. If it still doesn't you should try burning some files via the command-line to see if it works. I know how frustrating coaster-making can be when something isn't working right (what a waste of money and plastic).

[edit]I should really learn to read. You're using Slackware 10.2, not 12.0. Duh. Most of the above is garbage. If your older version of K3B has a burning group option, create a "cdrom" group (I don't think it exists in 10.2, but if it does just add your user to it) and add your user to it. Then add the "cdrom" group as the burning group. But I'm not sure if this will work (I've never used 10.2, and I didn't burn any CDs with 11.0). Try some command-line tools to make sure everything is working properly. Good luck...[/edit]

Hi !

I can see that you added the root as the burning group with the chown command, if you think that it works for you it is ok, but only the root user have permissions to burn cds ... now cheer up , you can make groups any time with the next command (sometimes command line is better than graphical interfaces)..

# groupadd burning (this will add the group, in this case will be "burning" group, you can name the group with the name you like most)

Now, we proceed to add users to the group (a group with users is a happy group, hahahaha ) In this case we will add a user to the group burning.

# gpasswd -a user burning (substitute "user" with your user, you can add many users as you want, but remember is a line per user ).

We have a group with users, but we want the group to have burning rights. Here, remember when you typed the chown command ? we can use it again to change the owner of the burning rights to the group, (this case is burning group, but you can change to the group you created instead of burning, remember, burning is just group example)

# chown root:burning /usr/bin/cdrdao
# chown root:burning /usr/bin/cdrecord

Next, we type

# chmod 4710 /usr/bin/cdrdao
# chmod 4710 /usr/bin/cdrecord

But i can see that you already applied the changes. After this, now you must be able to burn CDs and DVDs with K3B.

Hope this helps you with your burning quest . I need to read a lot how to do things in slackware

Greetings.

I appreciate the help T3slider. I have put my user name in the group(s) cdrom, audio, and video but I don't have a plugdev in 10.2 . I'm also running k3b 1.0.4 (latest release and I compiled it from source from www.k3b.org). I rebooted and tried k3b. I put cdrom as the burnng group in k3b and tried a simulation but didn't work. Showed no progress during write but finished showing 100% and had 0 kbs write speed. I have debug info I you wish to see the output/outcome. I did try burning a cd (thinking maybe it doesn't show progress during simulation) but another coaster. At least I'll have some coasters for my next party!!

I also appreciate your help animeresistance. I added group burning and gpasswd -a <myusername> burning. I then used burning as my burning group in k3b (I assumed to add this but you didn't say to so I hope I didn't make wrong assumption). I then tried k3b (without reboot) but came up saying couldn't find cd/dvd drive. I did notice that the permissions for /dev/hdc was 660. The /dev/hdc was 666 before changing to burning as the burning group in k3b. There is also a b in the permissions.

And you can see it's back to cdrom as group for now.

I have looked for a newer version of cdrecord ,because k3b is saying it can use my version (cdrecord 1.11a15) but it is outdated, but I can't find a newer version of cdrtools (I have cdr-tools-2.01). I don't know if the version I have is causing the problem or not.

I have not yet tried from command line but will read up on using cdrecord from man pages and give is a shot. I have the command for cdrecord k3b used in the debug file but not sure that will work straight from command line?? I hope this helps you to better help me. It's usually something simple that I (we as newbies) overlook or forget.

Thanks for the help!!
