 Posted: Mon Feb 07, 2011 12:17 am Post subject: [SOLVED] K3b cant find DVD drive (What's New?) |
 |
|
I hate bothering you guys about every little thing I can't figure out, but if I could figure them out, I wouldn't need to bother you....
Lets say I want to burn a DVD ISO, I fire up K3b, it gives me an error message that indicates that it can't find my DVD drive.
If I run K3b as root, I get an error message that indicates that app-cdr/dvd+rw-tools is not installed. I currently have version 7.1-r1 installed. However, I can mount the DVD drive and burn an ISO without any problems.
This to me means it is a problem with permissions. I have looked up how to resolve this issue and came up with three dozens ways to fix it. I've tried several to no avail. Don't ask which ones I've tried, I don't remember.
What should I look at to determine what I need to do to resolve this issue?
Thanks!

Is your user in the cdrom and cdrw groups?

Does | Code: | | $ cdrecord --scanbus |

Maybe hald is not running? Dbus?
How about ls -l /dev/sr*

K2b's System Check is what gives me the error when I first start K3b.
"It gives me an error message that indicates that it can't find my DVD drive."
| Quote: | No optical drive found.
K3b did not find any optical device in your system.
Solution: Make sure HAL daemon is running, it is used by K3b for finding devices.

I don't know what you mean by Dbus, but Hald is running:

As i take it, dbus policy has changed.
Being started by a user (to see log run it from console), k3b can't find a drive:

For the same reason krusader(run as user) can't get a list of mounted drives anymore.
I think we are to give the user some rights. |

Ok, how do I give myself these rights?
This is the lack of error I get when I run K3b as root:

I would say it is quite obvious that this is a permissions issue. Who do I need to give permissions to, K3b or me? |

In my searches for a solution to my problem, I found a file located at /usr/share/doc/k3b-2.0.0/ called PERMISSIONS.bz2.
It reads:
| Quote: | K3b needs some special permissions to work properly. Most distrobutions come with permissions that I don't like
very much and make problems when adding new CD/DVD devices to your system.
If you set up your system as follows you can be sure to never have K3b permission problems again.
1. Disable pam authentication for cdrom and burner devices in /etc/security/console.perm. Otherwise your permissions
will be overwritten when loggin in and it's not possible for two users to use K3b at the same time.
In my opinion one should disable this completely and create a proper configuration instead. The most annoying
issue with this pam stuff is that you cannot have two sessions with two different users running because the first
one owns all the sound and cd devices.
2. Create a cdrom or cdrw or whatever group (if it not already exists) and add all users that should be able to
use K3b to that group. You may also skip this step and let everybody use K3b. In that case simply use root as
the group and permissions 4711 and 666 instead of 4710 and 660 in the following steps.
3. Change the permissions of cdrecord and cdrdao to 4710 root.cdrom (substitute cdrom with the group from 2).
This way both will run suid root which allows them to increase their scheduling priority resulting in a more
stable burning process.
4. Change the permissions of all your cdrom device to 660 root.cdrom (substitute cdrom with the group from 2).
With devfs you may do this with lines like this (the first changes all ide cd devices while the second takes
care of the scsi cd devices):
REGISTER ^ide/host.*/bus.*/target.*/lun.*/cd PERMISSIONS root.cdrom 660
REGISTER ^scsi/host.*/bus.*/target.*/lun.*/cd PERMISSIONS root.cdrom 660
In case you are not using devfs you may determine the devices by running K3b once as root and looking in the
device settings. The corresponding devices are listed there.
5. Change the permissions of the generic SCSI devices to 660 root.cdrom (substitute cdrom with the group from 2).
Both cdrecord and cdrdao use the generic devices to access the scsi drives. So you don't need to perform this step
if you only have IDE devices.
Use a line like the following for devfs:
REGISTER ^scsi/host.*/bus.*/target.*/lun.*/generic PERMISSIONS root.cdrom 660
In case you are not using devfs the devices are /dev/sg*.
|
This file seems to indicate that I need to give the cdrw and cdrom groups more permissions, but doesn't seem to specify how to do that. I know how to change the permissions of a file, which is all I can seem to find online, but I don't know how to change the permissions of a group. I also don't have a /etc/security/console.perm....
I guess, if no one has any other ideas, how do I change group permissions? |

Try not to mess with things you don't quite understand.
KDE upstream tends to give misguided advices anyway.
Anyway, for KDE <4.6.0 you still need to be in plugdev group (it's a hal thing). |

Your kidding me all I needed to do was add myself to plugdev!? If only I had known that a year ago... lol
The device notifier shows up now when I put a DVD in the drive too!
Thanks for your help! |

Well, given that KDE packages tend to be stabilized quickly, it's not that helpful,
given 4.6.0 changes. |

I've got the same problem.
When I performed the the above function I got
nothing.
if I do the following I get:
bbox / # ls -l /dev/sd*
brw-rw---- 1 root disk 8, 0 Mar 13 16:49 /dev/sda
brw-rw---- 1 root disk 8, 1 Mar 13 16:49 /dev/sda1

brw-rw---- 1 root disk 8, 3 Mar 13 16:49 /dev/sda3
brw-rw---- 1 root disk 8, 16 Mar 13 16:49 /dev/sdb
brw-rw---- 1 root disk 8, 17 Mar 13 16:49 /dev/sdb1
brw-rw---- 1 root disk 8, 32 Mar 13 16:49 /dev/sdc
bbox / # ls -l /dev/hd*
brw-rw---- 1 root disk 3, 0 Mar 13 16:49 /dev/hda
do that mean I've got something setup wrong in my kernel? |

@DancesWithWords: as a start, complete the libata migration.
Hard to tell if it helps, but it shouldn't hurt. |

See quote for gentoo kernal doc's.
| Quote: |
Additionally, your storage devices will be treated as SCSI devices, which means SCSI disk/cdrom support is required too. Your SATA hard disk will be named as (e.g.) /dev/sda and your SATA CD/DVD drive will be named as (e.g.) /dev/sr0. |
So I'm not supposed to have a DVDRW with a /dev/sr0 it is /dev/hda as it is supposed to.
But now I'm back to square one. How to get k3b to see my DVDRW?? I followed https://forums.gentoo.org/viewtopic-t-858965.html, but as someone pointed out k3b must have hal to work. So what now? Any ideas? |
