Knoppix and K3B

Hi everybody -

I got a question about K3b hanging up when I use a Live Knoppix Cd :

I've been using the Knoppix Cd for a while, and it got good to me, so I load it and play with it quite a bit

I've even been using it to surf and do writeup for my Site, and even burn CDs

Everything was everything, until I went to burn a CD (which, like I said, I've been doing)

Didn't work for whatever reason, so I closed the window out, but it didn't close the program, like the program was still running or something

Tried again, etc....

Nothing, it just hung, and wouldn't even reduce to the taskbar

So, being stooopid, I opened up another K3B window, figuring if I could get it to close down, it might re-set the perameters or something, and I could then close the original.....

Do I have to say it ??

Now I have two copies of K3B on my desktop, neither of which will close out....

What am I missing here ?????

I can't close out the session and re-boot or I'll lose several days work that I didn't get a chance to record -

Anyone have this problem before ?? Or have a solution ??

Pleeeeze...... I'd be eternally greatful if you could point me in the right direction....

Thanx.....

PM

"Now I have two copies of K3B on my desktop, neither of which will close out.... "

su to root. Then use the top command to find the PID of each of the K3B sessions which will not close out. Then use the kill command to close out those PIDs.

See:
man su
man top
man kill

Hi,
I've had similar problems before, if you can safely kill the process as root, restart K3B after you've configured it is the best bet.
To find & kill the root process for k3b I'd use (from the command prompt):

Code:

kill -9 $(ps -aux | grep k3b | cut -d" " -f4)

You may need to config k3b before using it, from the k3b application menu choose:

Settings >> Configure K3b...

I hope that helps..

Wow - you guys ROCK - the command line just befuddles <u>me</u>

Steve : It only gives me the first 25 or 26 processes -
the screen's too short, an it won't scroll - I moved the app to the top of the window and
dragged the window down till it hit bottom, but that's all I can get to....

Craig : While the prompt acceps the kill command, it doesn't recognise the "-9",
and it stops there....

ok,
If you use the parts that I gave in that long command seperately, it should work ok.
To get the pid of the k3b process..

Code:

ps aux | grep k3b

that will show all k3b pid's (2nd number in ps aux listing)
then kill the parent, (lowest numbered pid) for k3b with..

Code:

kill -9 <k3b-pid#>

you should see the k3b process wink out of existence pretty quickly, rinse and repeat if needed.

Hope that helps..

Code:

pkill k3b <return>
killall k3b <return>

pkill only should be enough, if the windows stays hanging around on your desktop then do this:

Code:

xkill

and then click the k3b windows you want to close, then restart k3b. But because it is a livecd it could take a while for k3b to load and i wouldn't recommend it to burn cd's from a livecd because it will need to load from a cd and write to a cd at the same time. Idk, just not a good idea unless it works for you.
