Probably because many focus on the newer aspects of Linux

But using rc.local is a good workaround and it works.

NeroLinux 3 does not see my DVD-RW when logged in as user, only device shown is the Image Recorder.
Able to use if logged in as root!!!.
Have installed with SELinux disabled, permissive and enforced, still cant burn as user. Any ideas

Please review the first page of this thread. If the solution there is not effective, please launch nerolinux from a terminal and post any error messages you recieve.

Thanks, the posted fixes seem to work. Adding the code in rc.local did the trick. Now able to use Nero in usermode.

hi there,

I was having simular issues with Nerolinux and Lightscribe Linux. Although the solution using rc.local does work I think it's better to fix it through Udev. There is one problem and also a bonus:

1 I was unable so far to get it to work as good as the devices Fedora 7 uses for cdrw/dvdrw's:

ls -la /dev/scd*
brw-rw----+ 1 jeroen disk 11, 0 jun 16 16:27 /dev/scd0
brw-rw----+ 1 jeroen disk 11, 1 jun 16 16:27 /dev/scd1

Yes that's right Fedora actually changes things to work just for you! If only I could figure out just how it does this

This is the result of my attempts with udev:

ls -la /dev/sg*
crw------- 1 root root 21, 0 jun 16 16:27 /dev/sg0
crw------- 1 root root 21, 1 jun 16 16:27 /dev/sg1
crw------- 1 root root 21, 2 jun 16 16:27 /dev/sg2
crw-rw---- 1 root disk 21, 3 jun 16 16:27 /dev/sg3
crw-rw---- 1 root disk 21, 4 jun 16 16:27 /dev/sg4
crw------- 1 root root 21, 5 jun 16 16:27 /dev/sg5
crw------- 1 root root 21, 6 jun 16 16:27 /dev/sg6
crw------- 1 root root 21, 7 jun 16 16:27 /dev/sg7
crw------- 1 root root 21, 8 jun 16 16:27 /dev/sg8

I have 2 dvdwriters, apparently these are sg3 and 4 So here's your bonus: by using Udev you only mess with the right device files.

On to the solution. Edit /etc/udev/rules.d/50-udev.rules and add the 'Custom parts' the first ones are already there so you can search for them:

# rename sr* to scd*
KERNEL=="sr[0-9]*", BUS=="scsi", NAME="scd%n"
KERNEL=="hd*[0-9]", BUS=="ide", ATTRS{removable}=="1", \
        OPTIONS+="ignore_remove"

#Custom Lightscribe
KERNEL=="sr[0-9]*",             SYMLINK+="sr%n"

(this makes Lightscribe software work if you have a Lightscribe drive)

ACTION=="add", SUBSYSTEM=="scsi" , ATTRS{type}=="1", \
        RUN+="/bin/sh -c 'echo 900 > /sys$$DEVPATH/timeout'"

#Custom Nero
ACTION=="add", KERNEL=="sg[0-9]*", ATTRS{type}=="4|5", GROUP="disk", MODE="660"

Now add your user to the disk group in /etc/group, reboot and you're in bussiness!

Thank you beertje, your suggestion worked.

Hey Beertje, Thanks for the solution, could you clarify on how to add the user to /etc/group.. do you mean your user name or nero? Sorry for the noobish question.

Another way for resolving problem

as superuser edit /etc/security/console.perms.d/50-default.perms adding /dev/sg* to <cdrom> definition ie.

<cdrom>=/dev/cdrom* /dev/cdroms/* /dev/cdwriter* /mnt/cdrom* /dev/sg*

Now after every login you do you'll get ownership of /dev/sg* character devices.

Problem whit this IIRC is that only user that has first login session (console) has owner rights over <cdrom> device class, so I'll suggest if that isn't desktop machine to change owner rights for group and maybe for others ie.

# permission definitions
...
<console>  0660 <cdrom>      0660 root.disk
...

hope that this will help some one...

you can set this with security permissions in /etc/security
precisely in console security for devices as I had mentioned in my previous post...
