[Solved] udev 091-3 breaks my local rules

bunnyhugh · 2006-05-07 20:43:09

Just done an upgrade to udev 091-3 but had to reverse it as it broke my local udev rules.

I have the following local rules for my usb mouse and wacom tablet

Quote

KERNEL=="event*", SYSFS{manufacturer}=="Logitech", SYSFS{product}=="USB RECEIVER", NAME="input/mx1000", MODE="664", GROUP="plugdev"
KERNEL=="event*", SYSFS{manufacturer}=="WACOM", SYSFS{product}=="CTE-430*", NAME="input/graphire", MODE="664", GROUP="plugdev"

Unquote

This gives me the nodes "graphire" & "mx1000" in "/dev/input" for my mouse and tablet which means I don't have to worry which USB port I plug them into xorg always works as the nodes are always symlinked to the correct device location.

After the upgrade to udev 091-3 the nodes are not being created, so "X" won't start (can't find the mouse).

It appears that the only change between 091-3 and the previous 091-2 is some tweaking og the rules, so does anyone know how I should modify my rules so that they work with the latest rules in 091-3?.

I have been fiddling with it for a few hours but not being a udev expert, I thought I'd ask for a bit of help.

Many thanks

P.S it may be my imagination, or due to rule problem I'm having but although nothing else on my machine has changed 091-3 seems slower during boot than previous versions.

latest udev removed /dev/mouse, causing synaptic not to work any longer. I have no custom udev rules.

Try adding OPTIONS="last_rule" to your rules.

Thanks for the suggestion. I'm at work at the moment so i'll try it when I get home.

I get the same problem. Here is the diff between the rules from udev 091-2 and 091-3:

[]$ diff udev.rules.091-2 udev.rules.091-3
> # only needed for kernels < 2.6.17

The only thing I can see affecting it is the transposition of a == for a =. Is this a bug?

ipw2200 was broken after I updated udev to 091-3 yesterday. I don't know yet if it works with 091-4. I'll report soon...

jani · 2006-05-08 13:24:34

udev 0.91-4 does the same thing, ie synaptic touchpad stops working so X doesn't start. Downgrade to 0.91-2 fixes it.

jason · 2006-05-08 15:19:01

ipw2200 wasn't working, but now is with udev 091-4.

Hi brain0

I tried this suggestion but it made no difference, upgrading to 91-4 made no difference either.
I'll see what else I can find

bunnyhugh · 2006-05-08 17:19:53

I now have everything working again. The problem was not with my local udev rules at all. it was a missing kernel module

I do not use /dev/input/mouse /dev/input/mice etc for my mouse and tablet in "X" I use /dev/input/event etc.

prior to 091-3 the kernel module "evdev" was always loaded for me automatically at boot time. From 091-3 this no longer the case, I have to explicitly load the module by placing an entry in the "MODULES=()" in rc.conf. Once I did this everything worked again.

I don't understand the in's and out's of UDEV so can't see why 091-2 loads this module and 091-3 dosen't, maybe someone can explain

nightfrost · 2006-05-08 18:35:33

Thanks a lot bunnyhugh. Loading evdev explicitly fixed my problems as well. Cheers.

Hi nightfrost

Glad my fix was of some help to you, it would be good to know why 091-2 and 091-3 behave differently with regards to this module though.

I have posted a bug report.

tpowa · 2006-05-09 04:59:34

fixed in new udev

jani · 2006-05-09 06:30:41

Yep, udev 0.91-5 fixes all my problems.

Hi tomk,

Thanks for filing the bug report. I didn't think it was a bug, I thought it was a deliberate change in the way things worked

Glad to see it is fixed in the lastest version. Many thanks tpowa

udev 091-5 didn't fix my synaptic problems

Doing some more investigations I have found that udev >= 091-3 no longer loads the kernel module "joydev" either, you have to load it manually or put it in rc.conf. Could it be that you are still missing a module? Try comparing the modules that are loaded using 091-2 and 091-3 or later it may give you a clue

I need to load evdev manually since updating to 0.91-5 from 0.91-2

Sigi · 2006-05-10 17:16:24

Loading evdev manualy solves my problem with synaptic. I just wanted to mention that this wasn't necessary before udev 091-3...

tpowa · 2006-05-10 17:17:59

yes that is what i would call a bug

tpowa · 2006-05-10 17:39:02

udev-091-6 will fix this
