Ubuntu Multimedia :: Lirc: No /dev/lirc0 - Actual Device Number Changes On Restart
May 30, 2010
My only issue that I can't figure out thus far is the remote. I'm using a Hauppauge Nova-T USB Stick, and generally the setup for the Nova-T 500 is good. No problem with lircd.conf, .lircrc etc. My problem is that the remote doesn't work on startup. Looked in /etc/lirc/hardware.conf and it says, as expected: REMOTE_DEVICE="/dev/lirc0"
Which doesn't work because I have no /dev/lirc0 (I do have a /dev/lircd). However, running /proc/bus/input/devices, I discover that my IR receiver is event5, so if I change the /etc/lirc/hardware.conf to: REMOTE_DEVICE="/dev/input/event5"
And restart lirc, it works fine. Unfortunately, upon restarting the PC, the IR receiver doesn't always have the same path - eg it could be event6 or event8 etc - so then I need to fix the /etc/lirc/hardware.conf again.
I've bought this remote control that sais it works in Vista, XP etc. without any driver. Basically it has a bunch of buttons that replace the mouse and a bunch of others that replace basic keyboard functions (arrows, enter, escape). It has a USB IR receiver so I thought I could simply use it as a lirc remote in Ubuntu.
However, it sais absolutely nothing on it except for "PCremote" so during lirc installation I have no idea what to choose. And, interestingly, I accidentally discovered that it works in Ubuntu, too, out of the box. Controlling the mouse and acting like a keyboard. Is there a way I can forfeit current functionality and just get it to work as a customizable lirc remote? Or even better, keep current functionality but change it only for certain apps (xbmc, vlc etc)?
I recently setup a new Linux server running Fedora 10. For some reason all ping response times are rounded to the nearest 10ms. For example, running the simple command "ping yahoo.com" give the following sample results:
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=12 ttl=57 time=60.0 ms 64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=13 ttl=56 time=50.0 ms 64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=14 ttl=56 time=40.0 ms 64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=15 ttl=56 time=50.0 ms
I could post a larger result set but its all the same... every response is rounded to a multiple of 10ms. This wouldn't be a big deal except that the server is running Nagios for monitoring so accurate stats are important. The Nagios check_ping and check_icmp commands are also returning rounded off results. How can I get ping to simply respond with the actual response times rather than a rounded off number?
This isnt a linux related question as such, but I'd still like to ask.
I have purchased a 1tb external usb hard drive, which came with its own power supply, and the HD device is connected to the power mains 24/7.
However, there is no on/off switch on the actual device, and I dont want to have it permantly connected to my computer, perhaps only for an hour or so everyday.
Could I harm the usb HD by regularly pullling its usb cable from the computer usb port? (ofcourse I would unmount it first).
I am running Ubuntu 10.10 and am trying to get lirc to recognize my pcusa mce remote control. I have been working on this for a week and have not had any success. Please note that I am very new to Linux. I am comfortable moving around in the terminal but most of anything else that I do in the terminal is just following instructions.
This is the remote that I am using:
[URL]
When I run
cat /proc/bus/input/devices
I do not see anything that could be the remote. I have tried plugging the USB receiver into my Ubuntu 10.10 net book but it doesn't see the receiver either. I do not have a windows machine that I can test the remote on but I plugged the receiver into my iMac and I did get a red LED lit that I haven't seen on the Ubuntu machines.
When I run irw and press buttons on the remote I see nothing on the terminal.
When I run:
sudo mode2
I get:
mode2: could not get file information for /dev/lirc mode2: default_init(): No such file or directory
I have tried mode2 both with lirc running and stopped and I get the same response either way.
I have confirmed that there is no /dev/lirc but there is a lircd in /dev (it's not a directory). Also I had read somewhere that lirc doesn't work under Ubuntu 10.10. Is that the case?
I have recently built a new Ubuntu 10.10 (64bit) and installed MythTV and LIRC.I have correctly (?) configured LIRC for my specific IR Blaster on the serial port. Using the test send (see below), nothing happens - ie none of the pins on the serial port change state, and hence my IR Blaster hardware does nothing.

I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:
[Code]....
I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:
Not many people read my previous item (URL...). I guess my title wasn't good.After reading my previous item, can someone answer the following questions:Has anybody have an idea why my lirc directory is removed after every reboot? Or how can I create this dir before lirc is started?
I'm setting up a gui-less music server so there's no login, and I've tried using mplayer's lirc interface as well as irexec (sending mplayer slave commands to a fifo). But I can't get mplayer to work unless I start either irexec or mplayer from a logged in session. So my S99test is something like:
If I use the "mplayer" line, I do hear music at startup, but no lirc control. Yet if I log in and kill the mplayer and rerun S99test as root, all works fine.
The only thing I have found so far which does not work for me after upgrading to 10.04 is the ability to change the master volume via LIRC and the pulseaudio lirc plugin.LIRC itself is working, I can verify it recognizes my remote control input by using irw, and all other portions of my lircrc file are executed correctly, such as my On Screen Display. However, no changes are made to the system volume.
I have already reinstalled the lirc pulseaudio plugin to no avail.Can anyone else confirm if this does/doesn't work on their own system?
I use Mythbuntu 9.10 with an IMON PAD IR/VFD. Everything is fine except that two buttons (MyDVD and menu) fire their event twice. In that case, I'm not talking about a normal repetition in case of a long button press but they fire their initial events twice.
Here is what irw shows: 0000000029a3d5b7 00 MyDVD iMON-PAD 0000000029a3d5b7 00 MyDVD iMON-PAD 000000002ba385b7 00 Menu iMON-PAD 000000002ba385b7 00 Menu iMON-PAD
I pressed the buttons only once each - and not long enough for a repetition. For all other buttons it's fine. As far as I understand, using the .lirrc file to cope with repetitions is no valid approach (at least it didn't work for me) because the events are all numbered with "00", and not with "00", "01",... - so .lircrc is out of this, right?
I have a bare Ubuntu install that I use to run Xbmc. It has been working perfect for a month. I reboot it every few days. This morning I decided to reboot when it came back up my remote stopped working. I hadn't done any updates since I build the box. Unless Ubuntu does them without asking. Here is the dmesg log
I've got an Antec Fusion V2 chassis with a built in ir receiver.I've setup lirc on my system, and I can get irrecord to see my remote input and build a config file.I cannot get irw to work, and subsequently no activity on my HTPC.I'm running XBMC Live Further Reading:I've asked two questions on the Live community forum, however it's a slow process and the helpful responses have only taken me so far. These threads include some debug logs and troubleshooting steps.Question 1Question 2I'm wondering if this is something really basic that might simply be missing. The biggest problem here is that Linux changes so fast that information that was valid a year ago is completely obsolete now.
I have an Antec Fusion htpc case which has a volume knob that uses lirc. I also have a PVR-350 tv card that also uses lirc. The problem is that every time I reboot both devices switch places between /dev/lirc0 and /dev/lirc1 which results in a not working remote. I tried following the instructions on [URL] to make the lirc device static, but when I do a 'cat /proc/bus/input/devices' only the volume knob shows up. My PVR-350 remote isn't listed.
I am not able to play certain movie files with MPlayer since a few days: Code: MPlayer dev-SVN-r32749-4.4-openSUSE Linux 11.2 (i686)-Packman (C) 2000-2010 MPlayer Team Can't open joystick device /dev/input/js0: No such file or directory Can't init input joystick mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support. You will not be able to use your remote control.

I am not sure which filetypes are affected by this bug, but I can play *some* files. The specific file here used to work a few days ago. Code: kalle@hoppers:~> file somefile.wmv somefile.wmv: Microsoft ASF The only major thing referring to multimedia in the past few days I remember is installing 'h264enc' from Packman, however, meanwhile I uninstalled this package, yet the problem persists.
Code: kalle@hoppers:~> grep h264enc /var/log/zypp/history 2011-01-15 20:11:53|install|h264enc|9.2.4-0.pm.1.1|noarch|root@hoppers|Packman|c5bd1d534726472929134e5acc8f66492c52c51b 2011-01-20 22:06:20|remove |h264enc|9.2.4-0.pm.1.1|noarch|root@hoppers The only way of solving this was moving MPlayers config, but that did not help either.

i have some issues running twinview through my laptop and an additional monitor. i currently have the nvidia settings such that the monitor is the primary screen. however, whenever i click full screen in videos or another application, it maximizes in my laptop screen. also - when i maximize videos videos, the screen fills up, but the actual video size doesn't tend to increase (it doesn't stretch to fit). is this an adobe problem? ubuntu 10.04, nvidia driver v195, dell latitude d630 laptop.
I'm using a laptop and running a secondary monitor to my TV. My laptop has ATI HD 3400 video card. The TV has a higher resolution than the laptop's monitor. When the video is full screened on the TV, the actual video uses the resolution of the primary monitor and not the second.
I'm currently running Ubuntu (w/ GRUB) and Windows XP. I'd like to remove Ubuntu and run the recovery on Windows XP because it has started not running correctly. The computer is about 5 years old and I figured I'd just wipe it clean and start over (read: remove Ubuntu and reinstall windows via the recovery console).
I intend to follow the tutorial here: [URL]
However, I'm confused about determining the boot device number for Windows. I've run "sudo fdisk -l" and I can identify the windows drive in the list it says:
Whenever I choose "Restart" from the GDM screen, GDM appears to shutdown, and the first TTY is displayed with a login prompt at the bottom (assuming I haven't used that TTY). I am by no estimation a patient individual, but I waited a solid minute or two for something to happen, but nothing ever did. I end up logging in as root on that TTY and running "shutdown -r now" to get the job done. This is a shared computer, and ideally any user should be able to perform shutdown options graphically from GDM.The only mentioned workaround doesn't apply to me as I am using the nvidia driver, not intel.
How can I know what number descriptor is used by my usb device indicate via libusb_device_handle structure ? I can't find declaration of libusb_device_handle structure. I need this information to use poll() function where I need decripttion number of device.

I've decided to toy around with LVM and mdadm this weekend. I can get everything working, and all is well, until I restart. After that, I no longer have any /dev/md0 device, which during the auto mount process, causes an error. I've looked through several HOWTOs, as well as the LVM/mdadm man pages, and I believe I've tracked it down to mdadm's "assemble" that is needed (so that LVM can see the md0 device).
Not exactly sure how to go about having this occur during the boot process to ensure that the LVM mapped drive is available for when fstab is read. In case it helps this is a base install of 10.10 server 64. I have four drives, the first is used for the OS and is not in the RAID array (nor LVM). The second and third are RAID1 (/dev/md0) and there is a volume group associated with /dev/md0. The last is a LVM, but not RAID, and it has its own volume group.
when it comes to linux, but like the idea and hope one day to get away from microsoft all together. This is the second time I have tried to install ubuntu on my eeepc 1000HG in addition to windows 7. The first version was karmic koala netbook remix, and yesterday it was lucid lynx netbook remix. Its annoying because before the update packages are downloaded and installed it runs smoothly, even additional applications run with no problem, but after restart to complete installation the following error message appears.
error: no such device: 5290ea6f-1bdf-4eda-b56e-2f282662e188. grub rescue>
Named has been working fine for months on Fedora core 14 with updates current.a few days ago it stopped working. I tried a service named restart and received the error message: stopping named: umount:/var/named/ chroot/var/named: device is busy.I tried using kill process, which did not work. However if I use kill 9 <named process>, followed by service named stop, I can then restart the service and it works for a number of hours (less than a day), then stops again and produces the error message above when I try to restart it.I can get it working again using the procedure above, but only temporarily.
To test stability, I rebooted the system, but on reboot, the array wasn't assembled correctly. Basically it had one device in "md_d2000", as a spare. So I stopped that device with
I don't have any important data on the array yet ... so I zero'd the superblocks on all devices, deleted the partitions, and started over .. here I go again:
I installed ubuntu today by installing Wubi and after downloading i rebooted computer and selected ubuntu but i got an error saying 'Try (hd0,0): FAT16: NO WUBILDR' and there was few more but i forgot and at the end it says 'Cannot find GRLDR in all device Press CTRL+ALT+DELETE to restart'. it used to work when i had vista...
