Got udev working, now what?!

TheCoop · Posted: Sun Jan 18, 2004 10:28 am Post subject:

ah, it works now

. The problem was that /etc/udev/udev/conf hadnt been updated to put the database into /dev so udev can write to it. Sorted and working on 2.6.1-love5

. The only problem is that since I have two monitors on my nvidia card, I forgot to create /dev/nvidia1, so X locked up on startup. Sorted now thou

Someone should email the udev ppl and say that its working fine now...

just one question, I want /dev/cdrom, /dev/dvd etc to be symlinks to /dev/hdc etc. In udev.rules you can tell it to move /dev/hdc to /dev/cdrom and then symlink back to /dev/hdc, but I just want a symlink to /dev/cdrom. How would you specify that?

Tried pure udev as per Decibels instructions.
Mouse was on /dev/mouse0 with udev-013
and on /dev/input/mouse0 with udev-013-r1.
I am running with kernel-2.6.1-mm4 and everything works fine except the Shell-console which shows no bash promp and does not accept keyboard input.
I am using kde-5 from 'iamlarryboy'

im not using devices.tar.bz2 anymore, its all specified in /etc/udev/udev.rules. Nothing is stored over reboots anymore, its all created dynamically. Whats the correct line in udev.rules?

you can have a look at my current /etc/udev/* files at http://thecoop.dyndns.org/udev/udev.{conf,permissions,rules}

you need to substitute {thing} for each one you want to access
eg: http://thecoop.dyndns.org/udev/udev.conf

uglyman · Posted: Sat Jan 24, 2004 1:01 am Post subject: alsa + udev = problems?

Hi guys,
I was on board for the initial run of this 2.6 + udev adventure, but then my IBM deathstar crapped out on me. It took me a while to score a couple more hard drives, and now I am FINALLY getting it all running again. btw thanks for all the hard work you guys have done, since I was away.

I haven't tried the udev only setup, disabling the tar ball thing. I would like to get it working a little better first.I have 2.6 (no devfs compiled) with alsa compiled in, and I have udev.

now my main issue may or may not be udev related. When I access certain things in the dev directory I get errors about no such device or address. I must say that MOST things have worked great, and the few holdouts are rather obscure. This is making it tough to know if udev is my problem, or if maybe it is another issue. I am hoping somebody here has some hints for me.

two examples of the No such device or address problem:
trying to load sound fonts for use with midi on my emu10k1:

$ sfxload /path/to/.sf2
/dev/sequencer: No such device or address

trying to do anything to /dev/lircd gives similar errors.

these are the only two problems I have noticed and it is very likely that I just have something set up wrong with alsa or lirc. I didn't want to lay this on the rest of the community without trying here first though, because udev + 2.6 is still kind of uncommon. if you think my problem is related to something off topic, feel free to PM me or IM me.

thanks for the help!

later
uglyman

on mine /dev/sequencer is a symlink to /dev/sound/sequencer, does /dev/sound exist? if not have you got alsa-oss compatability compiled into the kernel?

aufrank · Posted: Sun Jan 25, 2004 1:38 am Post subject: still getting /dev/console error

I tried running a system with udev dynamically discovering all devices, rather than with the tarballs, as shown in this thread. I've tried this with 2.6.1-mm5 and 2.6.2-rc1-mm2, both with udev version 013-r1. all of the files in /etc/udev/ are current with the latest examples posted in these forums.

in each case, when I boot I get an error that /dev/console is not available. I do have unix98 tty support compiled in, as well as /dev/pts support. I do not have devfs support built at all.

when I look in /var/log/messages, I get a _ton_ of messages about nbd (network block devices)... here's a sample:

uglyman · Posted: Sun Jan 25, 2004 2:30 am Post subject:

hi thanks for the tip TheCoop!
I see that I dont' have /dev/sound but I do have /dev/snd.
I have /dev/snd/seq and if I simlink to that and sfxload, I get an error that there is no sound card.

vary strange. well I found out that I need to recompile my kernel for some other stuff I want to change, so I am planning to just double check all the sound settings as carefully as I can. I am in the middle of an emerge -UD world right now, so I am gonna wait for that to finish anyway.

I have seen some people recommend compiling alsa directly in, and some say to do it all as modules. which do you guys recommend? I believe I had it working on my old (now broken) hard drive, with it compiled in, but I can do it either way.

thanks

The only thing that worked for me was a combination. Here is the post:

thanks,

looks like I have more reading to do

I got my stuff updated so after I etc-update I will try the kernel again.

later,

w00t!

ok so I ran snddevices from the alsa-driver package again. I am 99.999% sure I already did this once, but for some reason the problems with sfxload stopped. so midi works.

thanks for the help

ps: can anyone explain this to me? no no wait... its working now so I am gonna go ahead and NOT CARE AT ALL :lol:
