Q: Compiling K3b fails with errors like this:
|
|
base_k3badvanceddataimagesettings.cpp:185: invalid use of undefined type
|
|
`struct KComboBox'
|
|
base_k3badvanceddataimagesettings.h:17: forward declaration of `struct
|
|
KComboBox'
|
|
A: The QTDesigner tool 'uic' is not able to find the kde widget plugins.
|
|
To solve this run 'qtconfig' and add '$KDEDIR/lib/kde3/plugins' to the plugin search path
|
|
(replace $KDEDIR with your kde base dir).
|
|
|
|
|
|
Q: K3b thinks my SCSI device is IDE.
|
|
A: If you are using the rpm from SuSE your version of K3bSetup is not able to set the
|
|
permissions that K3b needs the devices to have. The SuSE guys seem to think messing with
|
|
permissions is too dangerous. It is recommended to always compile from source to have all
|
|
K3b features.
|
|
|
|
|
|
Q: Where has all the fancy graphic gone?
|
|
A: Most likely you installed K3b in the wrong directory. All KDE programs are installed in the
|
|
KDE dirtree (SuSE: /opt/kde3, RedHat: /usr). If you compile K3b from source it defaults
|
|
to either $KDEDIR or /usr/local. To install in the correct directory you need to specify the prefix
|
|
to configure like this:
|
|
./configure --prefix=`kde-config --prefix`
|
|
That will install K3b relative to the correct path.
|
|
|
|
|
|
Q: The linking always breaks with the missing -laudio.
|
|
A: You need to install NAS.
|
|
|
|
|
|
Q: Where can I find K3bSetup2?
|
|
A: K3bSetup2 is a KControlCenter Module. You can find it in the System Administration section or start
|
|
it manually with "kdesu kcmshell k3bsetup2".
|
|
There also is a script since K3b 0.11 called k3bsetup.
|
|
|
|
|
|
Q: My writer supports writing at speed X but K3b shows Y as a max.
|
|
A: K3b determined the maximum writing speed the first time you start it. Since the speed reported by the
|
|
writer always depends on the mounted medium this may not be the real max.
|
|
To manually change it open the K3b settings in the device section and click on the value. You will
|
|
be presented with a spinbox which allows to change the speed.
|
|
|
|
|
|
Q: Writing fails with the following cdrecord message:
|
|
"Cannot allocate memory. Cannot get SCSI I/O buffer."
|
|
A: Since kernel 2.6.9 suid root programs are not allowed to use the SCSI subsystem.
|
|
To solve this issue either configure cdrecord to run without root privileges: chmod 755 /usr/bin/cdrecord
|
|
or run K3b as root (which is not recommended but works also).
|
|
|
|
|
|
Q: Writing fails with the following cdrecord message over and over again:
|
|
"Error trying to open /dev/hdc exclusively (Device or resource busy)..."
|
|
A: You are using a patched cdrecord version which tries to open the device exclusively which fails because
|
|
your are probably also using automounting. The solutions are to disable automounting altogether (and this is
|
|
the recommended solution as automounting can cause other more serious problems with CD/DVD writing) or to
|
|
install a non-patched cdrecord version.
|
|
|
|
Q: My DVD drive supports 16X but K3B keeps burning at 1X! What's happening?
|
|
|
|
A: Your kernel most likely didn't apply optimal settings for your drive when it detected it. You can find out
|
|
what are the current settings of your drive with the command "hdparm -v /dev/dvd":
|
|
|
|
/dev/dvd:
|
|
IO_support = 0 (default 16-bit)
|
|
unmaskirq = 0 (off)
|
|
using_dma = 0 (off)
|
|
keepsettings = 0 (off)
|
|
readonly = 0 (off)
|
|
readahead = 256 (on)
|
|
|
|
The following options are known to maximize burning and playback performance:
|
|
|
|
hdparm -d1 -c1 -a8 -u1 /dev/dvd
|
|
|
|
To make these options permanent, a quick and dirty solution is to include the command in /etc/rc.local.
|
|
Consult your distribution documentation for a tailored solution.
|
|
|
|
Some drives have buggy DMA support. If you experience instability, leave these options disabled.
