Hi

I'm trying to burn a data dvd with k3b but it's having problems reckognizing my external usb burner. I'm running slack 10.0 with 2.4 kernel and the device is reckognized as /dev/sr0 and I have it mounted to folder /home/herve/burner. I have no problems accessing that folder as a normal user

when I run k3b from the terminal I get the following error:

k3b: (K3bDevice:: DeviceManager) scanning fstab: /dev/sr0
k3b: (K3bDevice:: Device) Error: could not open device /dev/sr0for reading
k3b: could not open device /dev/sr0 (Permission denied)

I get this error when I run k3b as root:

QPixmap: Cannot create a QPixmap when no GUI is being used

Does anyone know how to resolve this?

Thanks.

Check the permissions of /dev/sr0. If in doubt, give a chmod 666 /dev/sr0, this should work. The chmod must be done as root.

The errors when starting k3b as root are because your X session is running under your normal user id. They should disappear when you start X as root (or do a graphical login as root). However, I suggest trying the chmod first, it's more easy ;-)

That almost worked, I chmod /dev/sr0 to 666
K3b now reckognizes the device but only when there isn't a blank dvd. The instant I take out a normal disk and put in a blank, I get the same errors (permission denied). When I try to mount the drive after insterting the blank, it fails (no medium found)

Any ideas?

Thanks

You can't mount a blank disc.

You don't need to mount the disc to burn it. Just put in the disc and run K3b.

I would try using "k3bsetup" to detect and problems with your setup, but it is almost certainly just a permissions issue. K3bsetup will also set the permissions on all the drives that it needs higher permissions on, though I generally like to use my own permissions to retain as much security as possible.

I tried running the setup but the drive doesn't even show up in the list of devices.
As far as k3b is concerned, it doesn't exist.

This is getting out of hand, i'm thinking of going to windows and doing the burning from there.
