Congratulations for providing this nice distribution. Very nice indeed! Hope the old tomes when Kanotix was one of the best (live) CDs available are coming back ...

Wish to stress that I am using this Kanotix Hellfire 2011-03 64 bit as LiveDVD.

Have two small problems :

1. Is there a way to choose the right sound Card.

Code:

kanotix@Kanotix:~$ cat /proc/asound/cards

 0 [SAA7134        ]: SAA7134 - SAA7134

                      saa7133[0] at 0xfc006800 irq 22

 1 [Intel          ]: HDA-Intel - HDA Intel

                      HDA Intel at 0xfc300000 irq 47

9 times out of 10 the system is choosing SAA7134 as default whereas I need the HDA-Intel. So no sound!
Any cheatcode when booting? Or any command on the commandline after booting to solve this problem?

2. Is there a means to disable ipv6 globally?

Thank you for attention.

normaly you can set the default sound device with a custom ~/.asoundrc but you set it by ID and if the ID flips in some cases that will not work
maybe pulseaudio is a good solution for that problem so you can configure your sound cards via KDE systemsettings (in IRC !pa factoids), but i don't use it - ask Kano for it, he has tried pulseaudio with alternative sound devices

for your second problem - is there a good reason why you want to do this? if yes what?
you can disable IPv6 global with a grub bootcode

Code:

ipv6.disable=1

if you want to disable IPv6 permanent without editing at boot menu, you can append your default grub command line with that via

Code:

perl -pi -e 's/^(GRUB_CMDLINE_LINUX=".*)"/\1 ipv6.disable=1"/' /etc/default/grub && update-grub

Thank you very much for prompt reaction. And all the info.

Your advice helped me to have a ~/.asoundrc which solves my problem. I am very glad. Hope I will have sound in all circumstances.

Yes, I hope so : to speed things up when browsing, especially with opera. Also to avoid that comment from mplayer.

Kindly note I am using the LiveDVD which uses isolinux to boot and not grub. Will use 'ipv6.disable=1' as bootcode and see if there is any difference,
Moreover I can't make options permanent since LiveDVD.

If you allow me : how to set the xkeyboard layout to 'us'? The boot code 'keyboard=us' doesn't seem to work.

You helped me a lot. Thank you,

well in live mode the default is us layout, thats why the german entry cmd line is much longer than the englisch one
there are the isolinux parameter "keyboard-layouts=..." and "keyboard-variant=..." that change the keyboard configuration

if you have a wrong keyboard layout (that should not be happen ^^) on hd installs, you can reconfigure it by

Code:

dpkg-reconfigure console-data;dpkg-reconfigure keyboard-configuration

PS: so far i know the latest Opera version has a fix for that IPv6 bug

I agree but nevertheless without any bootoption for the keyboard language I start with a 'de' keyboard (easy to modify)

Know nothing about that opera fix but know that firefox has a config option

Code:

network.dns.disableIPv6

Do not know if this has anything to do with ipv6 but when I try to listen to 'DW' eg via a browser I have to wait a long time until 20% (of the cache?) is filled. This takes a very very long time. Any way to change that 20% default value?

Thank you for your comments.

Regards.
