Hotplug Question

Pratt · 04-20-2005, 01:12 AM

Hi there, first off all, i just want to say, that i dont write/speak english very well, so pardon me, if my english sounds *rude*, or disrespectfull, i am a *English-Newbie*, trying to *hack* my way into the language...

My problem is that, everytime i turn on my PC, i have to wait, till the Hotplug recognizes my (onboard)soundcard (Its called something with Viaxxxx)... If i disable the Hotplug, the soundcard does not get recognized by my Slackware 10.1 ....
Is there a way to avoid that? i mean, to put the devices in some kind of list, so that i dont have to wait till the Hotplug does his thing?
How do i see what the hotplug recognizes?... I guess i have to do something like *modprobe -whatever* but im just a newbie... if someone could help me out there, that would be great...

And another bonus-question: ive got a really cheap/old usb Logitech webcam... and ive also have an analog PCI TV card.. the problem is, i cant get the webcam to work.. everytime i try to use it (No matter what program), ive always get to choose one *capture* device, which is somthing like *bttv*, and thats the name of my TV card.... Obiously, when i choose that device, i get to see the image of the TV card....
Can someone, kindly give me some pointers here too?

hi there,

in theory you could disable hotplut and "modprobe" everything that you see with lsmod.
how to do that?
1. lsmod > whatever
2. modify whatever in a way that looks like

Code:

modprobe snd_blahlbha
modprobe video_balla
..
..

change the permission of the hotplug script in a way that is not executable anymore.
and it is done.

regards

ps. and about your english skill don't worry. mine is much worst.

slackb0t · 04-20-2005, 07:31 AM

only one thing to add here.. I would not make the hotplug script not executable as it seems to cause other problems... I would pass the command "nohotplug" without the quotes to the kernel at boot..

Pratt · 04-21-2005, 12:13 PM

Thanks for the info.. just one question about de "nohotplug" thing...
I have to put de "nohotplug" flag in the Lilo.conf? , or do i have to do it via pkgtool? or, just type the comand as root?

And another question, do if i write: "modprobe snd_blablabla" once, i dont have to do it anymore?, or do i have to repeat it everytime i login?

thanks!

slackie1000 · 04-21-2005, 12:29 PM

hi there,

in your lilo.conf...

Code:

append=nohotplug

run lilo again...

regards

i have added that append=nohotplug to lilo.conf
when i run lil after saving it
i recieve Duplicate entry 'append' at or above line 6 in file '/etc/lilo.conf'

why is that?

If you look at line 6, like the error says, you'll notice the line

Code:

append = "hdc=ide-scsi"

You can alter that to:

Code:

append = "hdc=ide-scsi nohotplug"

--Shade
