I had exactly the same problem - neither K3b nor Brasero could see my
cd/dvd drive, which obviously is working because that’s how I did the
installation. After looking over the openSUSE Wiki, openSUSE News and
openSUSE forums last night and not finding any information, I’ve gone
back to Fedora 10. Too bad.
I’m using OpenSUSE 11.1, KDE 4.1.3, user account in users, cdrom. I
restarted my PC after every change: starting k3b both of my
burning-drives are o.k., putting in a clean cd to write, there flashes
the start-button, then the drive disappears!
Today, after a cold-boot, k3b works! But there is still a little bug:
putting in a clean cd to write keeps k3b in the status that it doesn’t
find a medium to write on. Taking out an old recorded DVD of my second
burning-device, putting in the same (!) clean cd and k3b works…
besides: graveman, a very simple burning-program, works out of the box
I have this issue under SuSE 11.1 and KDE 4.1.3
the block device sr0 (which is what the dvd and cd links point to) has
the permissions set to allow root and the disk group to have access.
everyone else is denied access (others group).
logged on as root and changed the permission. logged out of root and
back in as user. had correct permissions.
rebooted and the permissions reverted to disallow access to others.
Rebooted and logged on as user under Gnome. Had correct rights.
However, I cannot locate the script that controls the rights to
Also cannot get a script to work that changes the rights on log on.
An update from someone who has wrestled with this
problem. Apparently, it all has to do with permissions.
By default a user is not included in the “cdrom” group
or the “wheel” group. Also a user is not able to
use the “sudo” technique to execute commands that
are normally reserved for root.
So, the first step is to add yourself to the “cdrom” group.
You open Yast and go to the Security and Users tab, then go to
User and Group Management. Find yourself, edit the listing and
add membership in the “cdrom” group. Then you can mount the
cdrom and as a rsult, K3b and Brasero will work.
You can consult the advisability of being able to
run commands using “sudo” and edit /etc/sudoers appropriately.
Also, there are reasons why you might want to be a member of
the “wheel” group.
But just to use K3b, Brasero and mount cd’s and dvd’s,
having membership in the “cdrom” group seems to be
One final point. This is not a Gnome or KDE issue.
Actually I discovered you need to add the user to the “disk” group.
Here’s how I figured it out.
I checked my devices:
> koppie@cabernet:~> ls -l /dev
> total 0
> lrwxrwxrwx 1 root root 3 2008-12-22 02:58 cdrom4 → sr0
> lrwxrwxrwx 1 root root 3 2008-12-22 02:58 cdrw4 → sr0
> brw-rw----+ 1 root disk 11, 0 2008-12-22 02:58 sr0
I could see that my dvd-rw drive was showing up as sr0. sr0 only had
rw permissions for root and for the group “disk.” I also got a hint
from this post: ‘G(r)eek Bitches’ Blog: When Amarok doesn’t play audio
CDs…’ (http://tinyurl.com/9bzly4) (Also has good tips on adding
restricted formats, etc.)
I added the group “disk” to my user, logged out and back in, and huzzah
I had the same cd-rom access problem after a fresh install of 11.1 on a
ThinkPad T23. I used the drive to install from the DVD and non-OSS CD.
It worked fine. When up and running, KsCD would start loading, then
close. K3b could not see the drive. I followed trotter1985’s
instructions and put myself in cd-rom and disk groups. All is well now.
trotter1985, thanks for the detailed instructions, they made the fix
I installed 11.1 a few days after it came out and I was able to burn and
play disks without issue. Today, all of a sudden I couldn’t. Adding
cdrom and disk groups fixed it, but something is very wrong that this
happened. No, I didn’t update anything, but something got corrupted.
So it works, but who knows what problems being a member of the disk
group could cause?
Actually, it’s a bug in 11.1. The problem with the disk group is that
the members have raw access to -all- drives, which is even on a single
user PC a bit risky - imagine the havoc you could wreak with a misplaced
dd (didn’t know that when I wrote the blog post koppie is citing, have
updated it by now - sorry).
A safer solution proposed in the ‘Novell bug thread’
(https://bugzilla.novell.com/show_bug.cgi?id=408252#c14) would be to
give the cdrom group permissions for CD/DVD drives in the udev rules
(alternatively, I copied the solution to ‘our blog’
