Some hard questions I believe -Channel Bindings(soundcard), ntfs-capture and apm??

Nihongoga · 07-19-2004, 12:26 PM

1. How do I configure alsa to send sound to both my headphones and my speaker output? (Now I only got sound in my headphones, and nothing is muted in alsamixer). I use Soundblaster Live 5.1
My .asoundrc look like this.
pcm.!default {
type hw
card 1
}

ctl.!default {
type hw
card 1
}

I will include my alsaconf file in the end.

2. I have installed ntfs-capture and this program changed my fstab to
/dev/hda7 swap swap defaults 0 0
/dev/hda6 / ext3 defaults 1 1
/dev/hdb6 /g vfat defaults 0 0
/dev/cdrom /mnt/cdrw iso9660 noauto,owner,rw 0 0
/dev/hde /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
/dev/hdb5 /mnt/f captive-ntfs defaults,noauto 0 0
/dev/hda5 /mnt/d captive-ntfs defaults,noauto 0 0
/dev/hdb1 /mnt/e captive-ntfs defaults,noauto 0 0
/dev/hda1 /mnt/c captive-ntfs defaults,noauto 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

But the ntfs partitions are not mounted at boot time (not even when I log in as root)??...do I need to load some modules??....I haven't find any information about that...please help me!!
(and it would be fine if users were able to mount and umount the drivers too)

3. When I shut down my system I would like Linux to Power down(turn of the power), not only halt and say "Power Down". I have tryed to uncomment
/sbin/modprobe apm
and then also run modprobe apm
but that has not solved the problem. (It worked fine in XP so I have the right hardware =P )

4. Since I installed the NVIDIA driver the prompt got totally insane after starting KDE.
I Only see pixels in a lot of colors all over the screen. Although KDE is working well with Open GL and everything. I have a Geforce 4 MX 440. I believe this has something to do with the resolution or HSYNC or something like that, but how do I find out what to do and how to do it??

I welcome every solution

I would do :
1. rm all audio config files and /etc/asound.state too. After that run alsaconf & alsamixer to reset to defaults.
2. remove 'noauto' option in ntfs mount point lines in /etc/fstab
3. is your /etc/rc.d/rc.acpid executable ?
4. you have to be more precise concerning your nvidia pb, I did not get it all.

Nihongoga · 07-20-2004, 01:37 PM

Thank you!
1.The sound works fine now =) and (2) the ntfs partiotions are mounted at boot time and my users can access them =)

3.The users don't have permission to shutdown the computer =( (how do I fix that)
I haven't test if the computer power off if root run the halt command...I will try it now...
I run chmod 777 /etc/rc.d/rc.acpid ....what is that file for?

3.My nvidia problem is that when I boot up, the prompt is viewed as usual, but when I start X the nvidia driver seems to change the resolution even in the prompt to something not readable...just pixels all over the screen. When I shut down X the pixels are still there all over the screen, so everytime I exit X I can't see what I am typing in the prompt...very frustrating =P
I have tryed to install the nvidia driver again, but I suppose I maybe should delete some files first??....because just reinstall didn't help.
I hope that was a better explianation....

Thank you for all help I can get....

keefaz · 07-20-2004, 02:08 PM

For the video prob, try to run xorgconfig and after that, replace Driver "nv" by Driver "nvidia" in your /etc/X11/xorg.conf

Nihongoga · 07-20-2004, 02:41 PM

The xorgconfig solution did not work, pixels are still there all over the screen =(
And the system does not power off at power down =(
My users are not even able to shutdown the computer, how can I change that?

Thanks for all help.

keefaz · 07-20-2004, 02:49 PM

What is your monitor model and manufacturer ?
try man sudo to learn how to authorize user to run commands as root

gnashley · 07-20-2004, 03:31 PM

run visudo to change the permissions for users in the /etc/sudoers file

Nihongoga · 07-21-2004, 07:20 AM

Okay, I tried some sudo yesterday but I did not manage to let my users mount vfat and cdrom =(
I am not sitting at my linux computer now, so I can not give you my sudo file right now...

I have got a samtron 76E monitor and Geforce 4 MX 440 graphics card.

Nihongoga · 07-21-2004, 02:39 PM

Okey have tryed your solutions but I can not get it to work =(

Still wrong resolution at prompt when X has been started.
No Power off att shutdown
Can not get my users to have su permissions without typing su...
I would like at least mount, umount and shutdown, reboot to work at user level.

Here is my suedo file
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the sudoers man page for the details on how to write a sudoers file.
#

# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults specification

# User privilege specification
root ALL=(ALL) ALL

# Uncomment to allow people in group wheel to run all commands
#%User ALL=(ALL) ALL

# Same thing without a password
%User ALL=(ALL) NOPASSWD: ALL

# Samples
%User ALL=/sbin/mount,/sbin/umount
%User localhost=/sbin/shutdown -h now
%User localhost=/sbin/shutdown -r now

Thanks for all help! =)

keefaz · 07-21-2004, 02:45 PM

Hep, not good at all

Any user seems to be able to run any command without password on your system. (like delete system files, add bad modules to kernel, configure your sendmail to send spam...) with GNU/Linux network capabilities this is not good.

At least I would do :
#for stopping system
%users localhost = NOPASSWD: /sbin/shutdown -h now
%users localhost = NOPASSWD: /sbin/poweroff

You should be able to activate the APMD (advanced power management daemon) by editing the /etc/rc.modules file. Find the section which reads:

#### APM support ###
# APM is a BIOS specification for saving power using several different
# techniques. This is mostly useful for battery powered laptops.
# /sbin/modprobe apm

and remove the # from "# /sbin/modprobe apm"

T.

Nihongoga · 07-22-2004, 11:41 AM

Okay, but as you se I have created a new group User not users...so I believe it is not so dangeroes to have my sudor file look like the one I posted before?

The /etc/modprobe apm have I already tried and Yes there is a difference.When I have that line included I have to reboot the machine after power down because the power off button seems to be desable? =P so either I have to reboot or turn the power off by pulling the plug =(
However the power off button at least works when I don't include the apm argument but still I want the computer to turn off whithout me pushing any button =P

And still I have the resolution problem at the prompt... =(

However now I will

comment out %User ALL=(ALL) NOPASSWD: ALL%User ALL=(ALL) NOPASSWD: ALL
that might be a good idea?

Thanks for all help I can get

Nihongoga · 07-22-2004, 12:25 PM

Okay I found out what the graphic problem in the boot prompt was....I had set Vesa Framebuffert at console in my lilo, I changed that to VGA and graphics are working (but no cool pinguin at bootup though, but I think I survive without that) but still no turning off with the shutdown and the permission problems remains.
Thank you for all help I get, you have already been to very big help for me....I hope someone can help me with the turning off problem too =)
