 |

Hi.
I have a Dell Inspiron 9400 laptop with a SATA hard disk and an IDE CD/DVD writer. I've recently switched to KDE (3.4) but I'm still using Gnome (2.12).
When I want to burn a CD from Gnome, I "Go the CD/DVD Burner" in Nautilus, copy my files there and launch the burning process. There is no error.
When I use K3B, version 0.12.14 (as a user and I didn't SUID cdrecord since it's not necessary) , I get an "Access denied" error because K3B wants to use /dev/sg0, which is the controller for my SATA hard disk  .

$ ls -ld /dev/s[rg]?
crw-rw---- 1 root root 21, 0 Jun 1 11:57 /dev/sg0
crw-rw---- 1 root cdrom 21, 1 Jun 1 11:57 /dev/sg1
brw-rw---- 1 root cdrom 11, 0 Jun 1 11:57 /dev/sr0 |
I'm quite happy with that as it reflects exactly what I have on my system. Is there any chance I can have K3B understand it must use /dev/sr0 instead of /dev/sg0 for writing?

Don't know what I've done exactly but it looks like cdrtools were upgraded recently (although no major update of KDE occurred). Since then I don't have problems anymore burning DVDs with KDE. I haven't burnt any CDROM yet but I don't expect any trouble either.
I have now cdrtools-2.01.01_alpha10 and udev-079-r2.

Still solved. But the solution doesn't reside in upgrading K3B...
In the Advanced options. You must change the default burning group (you might have to check the box first), which is burning by default. Change it to cdrom and that's it. Also, on my laptop, there was a reference in the device list to a burning device at /dev/sg1, which I unselected to keep only the one at /dev/sr1. Since both are the same device only one suffices.
