k3b configuration dialog showing writer
Similar problem here with two ATAPI writers in both FC2 and FC3T1. A Samsung CD-R/RW SW-240B and a Plextor DVDR PX-712A. The Samsung is listed as a Reader, but shows burning capabilities for CD/RWs but not CDs. The Plextor is listed as a writer, but says no for "Writes CDs" and "Writes DVD+R(W)s", and says yes for "Writes CD/RWs", "Reads DVDs" and "Writes DVD-R(W)s" It is capable of all these writes. An older K3b I use in FC1 lists both devices as writers and writes CDs with both of these devices. I think "Writes CDs: no" is correct for all writing devices available to normal customers :) I checked my DVD writers entries, however, and it also states "Writes DVD+R(W): no", which is incorrect. could you please provide the ownership and permissions of the device files? e.g. # ls -l /dev/hdc or # ls -l /dev/scd0 File is mode 600, owned by the user currently logged in (as set by /etc/security/console.perms) Just checking - does the output change if you run k3b as root? newer kernels seem to be very restrictive about certain SCSI commands from non-root users, I think.. When running k3b as root (tested by logging into X as normal user, opening an xterm, doing "su" and then k3b) shows every SCSI drive in the system twice in the configuration dialog, but the SCSI writer is correctly listed as a writing device (albeit twice) Same problem here. Read from http://k3b.plainblack.com/index.pl/news2 the interesting information: (yes, booting a 2.6.7-1.517 kernel fixed it) Do not use Kernel 2.6.8 A patch that was introduced into the kernel shortly before the 2.6.8 release makes K3b and also the dvd+rw-tools unusable on Linux (unless run as root but that is not recommended). The very important GET CONFIGURATION MMC command is rejected by the kernel for reasons I cannot see and writing commands like MODE SELECT also fail (K3b cannot detect CD writers without it) even when the device is opened O_RDWR. Until this issue has been solved I strongly recommend to stick to kernel version 2.6.7. Update: The kernel guys are currently fixing the problem so the next kernel release should work again. :) Update 2: The problem is NOT fixed in 2.6.8.1 Update 3: Be aware that kernel 2.6.8 also contains the memory leak which makes it impossible to write audio cds, even as root. well, kernel 2.6.8-1.532 did not fix it. Still on 2.6.7-1.517. *** This bug has been marked as a duplicate of 130576 *** 2.6.9 fixes the problem Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
