I have a problem copying my udev rules from other distro to another pc running debian. My box is running debian without any DE and I want my USB disks to be automounted based on the label; I believe udev is the nicest way to do this task.
Anyways : my rules are (copied from archlinux wiki btw)
cat /etc/udev/rules.d/92-my-media-automount.rules
# vim:enc=utf-8:nu:ai:si:et:ts=4:sw=4:ft=udevrules:
# /etc/udev/rules.d/92-my-media-automount.rules
# Only work on sd*
KERNEL!="sd[a-z]*", GOTO="my_media_automount_end"
ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="my_media_automount_end" .....
I notice the directory is made successfully up inserting the usb HD, but the mount doesn't succeed. If I manually execute above command, the mount goes ok.
I have SSD drives without SCT support, because of this I want to tune /sys/block/device-name/device/timeout in order to force mdadm put these drives offline. So, I can see my drive like this:
/dev/disk/by-id/ata-OCZ-SABER1000_A22MJ061512000074.
Where can I tune /sys/block/device-name/device/timeout from 30 to 7 sec only for these drive? I don't want to use rc.local.
Can I create right udev rules for it in /etc/udev/rules.d?
I want to avoid any conflict with /lib/udev/rules.d.
Code: Select all# udevadm monitor --environment --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

I'm trying to allow non-root account to use avrdude to program mucrocontrollers. There are many articles online about how to do that, but it seems not to work for me. Every time i try to execute avrdude it says "permission denied". Here's "$ udevadm info --name=/dev/bus/usb/002/011 --attribute-walk" says looking at device '/devices/pci0000:00/0000:00:1d.1/usb2/2-1':
KERNEL=="2-1"
SUBSYSTEM=="usb"

However, after restarting udev, replugging the device, even rebooting the computer I still get "permission denied". The Vendor and Product match, so what's the problem?
I have just bought a DVB-T usb dongle to watch some TV. The software I'm using is vdr, which has to be started through the /etc/init.d/vdr service. I have created a udev script that executes the service on device insertion. It works nicely, however now when I boot up the computer it takes ages to get to desktop. I believe it is because of the WAIT_FOR part. But without this part, the service starts too soon because the usb dongle has been inserted but the firmware has not finished loading. Can someone point out an alternative way to do it? The script is here [URL].

View 6 Replies View RelatedI've just installed 'Testing' on a VMware server and after I completed the install with no problems, the system booted into the kernel and I noticed the following start up process error:

I have not seen this before and am not sure if it's related to the fact that this is a virtual machine and not a physical server or something else.
Here is a Screenshot.
I am using a 3rd party kernel driver that does not support udev properly. When I was using wheezy I placed the required device files in /lib/udev/devices.
The udev in jessie does not appear to support this. Is there any way to have udev create these device files or will I have to create then using a script at boot-up?
I have a trayless SATA hotswap bay that is really terrific for quickly attaching and removing SATA hard drives. I'm trying to write a udev rule to create a symbolic link to the device node for the drive that is attached through the hotswap bay (/dev/bay -> /dev/sdX). This eliminates any ambiguity when performing destructive tasks (fdisk, etc). I'm running squeeze amd64. I've read through several tutorials and have it working somewhat. Here's the output of udevadm info for a drive attached via the hotswap bay.

Here is my udev rule
DEVPATH=="/devices/pci0000:00/0000:00:11.0/host7/*", SUBSYSTEM=="block", SYMLINK+="bay%n"
This produces the desired behavior and gives me an fdisk-able device node. The problem I am having is that the "host" component of the DEVPATH varies from bootup to bootup. I'm just using on onboard SATA, host2-7, specifically host7. There is also onboard PATA, host0-1. It seems to just be random which "host"s are assigned to which controller. For example, the next time I boot the system, the onboard SATA will be host0-5 and the onboard PATA will be host6-7. In this simple case, I could just write 2 rules, one for each possibility and it would still be correct because of the different PCI addresses of the two controllers. But on systems with more SCSI (uh... libata, actually) controllers, a "host" file can point to different physical ports between bootstraps. This would be bad. Does anyone know of a way to write a rule to tie a device node to a specific physical SATA port on the motherboard/hba?
my thinkpad Edge 11 has some problems with the touchpad and the trackpoint, so i want to permanently disable the touchpad, but not the TrackPoint. Both are PS2 devices.

View 1 Replies View RelatedI'm trying to make a script that loads at boot and asks for user input before doing it's stuff. So I created a script in /etc/init.d/ following the example given there (skeleton file) and used update-rc.d to make it load before GDM.
But when my script requests user input, init doesn't stop, and goes on loading other services and loads GDM. I have to CTRL+F1 to get to my script. I want my script to pause the init system till it ends doing it's stuff and the the other services can go on loading.
I tried

I am learning japanese and I would like to be able to switch between english and japanese input while keeping an english interface. How would I achieve that? I am using KDE, by the way.
In the Kiten documentation I read that pressing Shift+Space would enable japanese input (built-in in Kiten, according to the documentation). But that does not seem to work in my system.
Is it possible to run kde in Wheezy without udev? I am asking this because the modesetting failure is manifested as soon as udev tries to populate the /dev directory.
View 6 Replies View RelatedI'm trying to run a script when a sd card is inserted into the drive. my udev rules are as follows:
BUS=="usb", KERNEL=="sd*", SYSFS{serial}=="058F63356336", NAME="sdcard", RUN+="/bin/mount /dev/sdcard"
BUS=="usb", KERNEL=="sd*", SYSFS{serial}=="058F63356336", OPTIONS+="last_rule", RUN+="/home/user/test"
The first line works, naming the device as "sdcard" and mounting it in the correct location. The second line should run a simple script to write a file with some text in it. If I run the script it works so I'm assuming it's not being done by udev but I done know why.
I updated my ubuntu recently but I found out that mupen64plus does not longer include a GUI. I have tried to configure my joystick with the instructions on their website but I didn't have an InputAutoCfg.ini file, although I created it and put the text in it but it still doesn't work?

Now I can't continue upgrading because every time it tries to finish the previous update and fails to process udev.
I don't know if it's relevant, but while upgrading udev for the first time, my laptop switched to tty1 on its own. When I switched it back to graphic subsystem, it still was in process of upgrading udev or systemd and after all failed to finish.
I am using Debian Squeeze on my laptop an now I want to write udev rules. I bought an USB enclosure for my old Desktop HDD drive (Debian lenny ).

I should create a sqeeze image and install it on other computers.Udev should detect network card (NIC) module and load it automatically at startup.How I understand /lib/udev/rules.d/75-persistent-net-generator.rules runs when udev starts, then writes to /etc/udev/rules.d/70-persistent-net.rules.The problem is, udev searches for this NIC on other hardware and the network cannot start.I can solve this problem easily using a startup script to delete /etc/udev/rules.d/70-persistent-net.rules file.
View 2 Replies View Relatedim using Debian (lenny) with 2.6.26 kernel, I'm trying to write udev rules in order to automount my usb pendrive, so I added this rules in udev:
SUBSYSTEM=="block", SUBSYSTEMS=="scsi",ATTRS{vendor}=="OTi ",
ATTRS{model}=="Flash Disk ", NAME="penna128M",RUN="/usr/bin/
pmount /dev/penna128M"
I use pmount to install the device as normal user If i connect my device to the usb port I don't see nothing in /media/penna128M, BUT giving at the prompt cat /etc/mtab the last line is:
/dev/penna128M /media/penna128M vfat rw,noexec,nosuid,nodev 0 0
The line in fstab about this pendrive is:
/dev/penna128M /media/penna128Mvfatdefaults,user,owner,auto00
Primary symptom: /proc/self/fd is there and normally populated, however /dev/fd is not. Process substitution therefore fails, because bash wants to create files under /dev/fd./dev/.static/ and /dev/.udev are populated. aptitude udev shows that the Debian package is installed, even though udev cannot be supported on this Xen vps (and, I believe, isn't supported by default until later stable versions of the Linux kernel).
I can solve the immediate problem by symlinking from proc/self/fd to /dev/fd, and putting the appropriate script in init.d. But are there any risks arising from Debian being misinformed about what my vps can do? And if so, what should I do about it?
Recently I have noticed that at times my keyboard will act as though shift is pressed. That is, letters are capitalized and when i press a key, its shift equivalent is shown. I actually first noticed this behaviour on fedora 12 beta (i believe fedora has been using udev/DeviceKit since F11). At the time of F12 beta I was not aware of fedora using udev. Where can I find a comprehensive guide to setup udev? Or if it all fails, how to re-enable settings in xorg?
