Ubuntu :: Bluetooth Dies Every Few Minutes?
Jan 15, 2011
My bluetooth manager is dying every few minutes or even every few couple of seconds. This happens when i'm using bluetooth mouse. Mouse works correctly cause i've tested it in windows. In the attachment there is dmesg output. In dmesg i keep geting lines like:
Quote:
[ 1463.864082] usb 4-1: USB disconnect, address 10
[ 1463.864601] btusb_intr_complete: hci0 urb eddf2900 failed to resubmit (19)
followed by reconnecting both, USB dongle and mouse. Then it works for a while and dies again, over and over. It also happens when mouse it idle (no matter if 5 seconds or 5 minutes).[URL]..

Am trying to set up a new system but am getting some strange behavoir. I've administered an Irix system before. I have opensuse 11.3 installed with gnome running. When i enter a bad user id in the windows login screen, the bad authentication causes the x window manager to crash and leaves the system in the ascii terminal mode login. I then have to login as root and do an init 3 , then init 5 to get the x server started again an get the windows login started. Has any one seen this behavior before and how can i fix this. Been hunting through /etc/X11/xdm to see what startup scripts could be causing this.

I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

i have a bluetooth modem (BlueSMiRF) that is connected to Arduino Duemilanove. I am trying to see serial communication messages from the bluetooth modem.
I have Blueman Device Manager that enabled SPP (Serial Port) and it says :
Code:
Serial port connected to /dev/rfcomm0
How do I see the serial communication on this?
I tried on console
Code:
$rfcomm listen 0
but it's stuck at
Code:
Waiting for connection on Channel 1
Is there any other way to listen (and also send) to serial comm msgs on bluetooth?

The bluetooth manager does not detect a bluetooth dongle .trying to use ndiswrapper to fix.I installed device manager and the results are shown below.i downloaded the windows driver suite. It has 4 .exe self extracting driver archives and a setupconfig.ini. The .ini file is below.I was able to extract one of the 32bit archives on a windows machine and it had about 8 .inf files that are titled weird and would not install properly using ndiswrapper probably because im using the 64-bit architecture. there are 2 64bit .exe's in the driver download, but how can i extract them in ubuntu and do i really need to install all 8 .inf files. also do i actually need to make a .inf file? if so how?

I have two servers, both running Ubuntu 11.04 Server. One is a web server, running only a LAMP stack and openssh-server. The other is running server daemons for TeamSpeak and Minecraft. Today, the game server just went down. I can access the LAN by using SSH to connect to the web server, and ping it from there. However, it won't respond to SSH or anything else. The server is a few kilometers from here, so I will be going there tomorrow.
This happened once before, probably about a month ago or something. That time, the web server was running just fine, but the game server was powered off. I thought there had been a power disruption, because when I checked the BIOS settings of the game server, it wasn't set to resume after AC power loss. The web server was set to do this, so it made sense that it would be up and running again after a brief power loss. There were also some news reports about power disruptions in my area.
The thing is, I changed the BIOS settings of the game server to make sure this wouldn't happen again. When I go there tomorrow, I will bring the server back up. However, I would like to know what caused this so that I may prevent it from occurring again. Is there a logfile or something that I can check tomorrow to find the problem?

Whenever I use Ubuntu, the internet seemingly dies out randomly. It never does this for windows 7. Could it be the router coincidentally dying, or is it a problem with Ubuntu?

I don't want to 'spam', (I had started a first thread about this some time ago), but I'm (still) experiencing problems with my internet: I can use the internet (I am connected through a simple switch) for some time, that is: surf the internet (in firefox) and download using vuze (azureus) but after some time, the internet connection 'dies' (downloadspeeds jump to 0b/s and I am not able to surf to any site in firefox). When that happens, the only 'solution' to this is restarting my pc.
I first experienced this when using ubuntu 10.04, so I thought that it was a 10.04 issue. I knew that when I had ubuntu 9.10 (karmic koala) installed, this didn't happen. So today, I installed karmic koala, but much to my surprise I am experiencing the same problem. I used 'lspci' to find out what NIC is in my pc and I found out I have the following NIC: 00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 78 ) I'm suspecting the NIC to be the problem. Is this probable? If so, I want to buy a add-in network card (simple one, not a gigabit card)

This can't be duplicated by anything specific, but I know it's not out of RAM at this point. The console keyboard and mouse are inoperational, and the monitor display seems to be going through test patterns, which turns out to be that the monitor is trying to sync to video output which is switching on about once a second. I can ssh into the box and see that many processes that were running are no longer running, for example gnome-session... and that once per second there is a new X process invoked with a different auth-for-gem parameter, per below:
/usr/bin/X :0 -nr -verbose -auth /var/run/gdm/auth-for-gdm-Kynptf/database -nolisten tcp
(one second later...)
/usr/bin/X :0 -br -verbose -auth /var/run/gdm/auth-for-gdm-GfBhRk/database -nolisten tcp

I am running 9.10 on a HP Compaq. Every few days X will die. The screen goes blank and will not display anything. I have to SSH in, but even trying various commands like gdm restart does not help. I eventually have to reboot the box. Below is a snippet (hopefully not too large) of dmesg:
/dev/sr0 on /media/cdrom0 is a CDROM, but I dont think thats the issue.

I recently installed the vt6656 wireless pci card that came with my zotac motherboard. I can associate with my ap and get an ip address successfully. When I disconnect my ethernet cable, however, my wireless interface stops responding (can't ping it). The box itself is in a place where I don't have a monitor connected to it so I cant see anything since my ssh session gets killed as soon as I disconnect the ethernet cable.
What would be the reason why the ehternet cable being unplugged, disconnects my wifi card as well? Does something get triggered? I did some testing with iptables, blocking the 8080 traffic to the wired interface, and noticed that the 8080 traffic also gets blocked to the wifi ip. I'm afraid that this never worked properly to begin with.

It has been happening to me since I started to use this laptop from the company for a linux test bed. Several times a day, when I do something from the command line, for example running an application connecting to another host on the internet, etc,it comes to a freeze and does not come out of it. I can not do anything else than a forced reboot from the power button, because the keyboard and the mouse do not respond. This work laptop is a lenovo W500, running on ubuntu jaunty, release 9.04. I have not encountered this problem before with my personal laptop though. My person laptop is a lenovo X61s, running on ubuntu karmic, release 9.10Should I reinstall the work laptop with some other version of ubuntu? Could it be some hardware problem ? What tools should I use to diagnose

I know there already a LOT of posts on the forum about pulse audio. I had some problems upgrading from Karmic to lucid, Pulse just kinda dies, but I left it be. Recently I brought a fresh 1TB hard disk and decided it was time for a clean install of 10.04 to fix that. I am running of a clean install, only additional packages I have pulled down are the Nvidia driver, wine, and VLC.. the rest is 'out of the box' config. Have tried reinstalling 3 or 4 times, I get the same sound problem each time. Pulse works fine to start with, I can play music, play warcraft under wine with sound.
However as time goes on I find that the pulseaudio process takes up more and more cpu time. Eventually it hits about 90% plus then crashes out. The system hangs for a minute, then resumes with no sound. When I run "top" the pulseaudio daemon is no longer running. The only way to get sound back is to manually "Pulseaudio -D" or to reboot the system. This isn't just "a warcraft problem". It happens with Spotify (also under wine) Rthymbox, and VLC. A friend suggested I run the Pulseaudio daemon with a higher cpu importance? Is that sensible? Are there any pages where i can read up on how better to configure pulse? I have read lots of guides about linux sound problems and most seem to be about alsa not pulse.
My hardware info is included below:

When I start Audacious and make it play music, after a random time the player
freezes up and the music stops playing. I have to make Audacious force quit and restart it, then it works for some time again. When I play a ..... video (in Firefox), it plays fine for some time and then it loses sound and either continues playing silent or the video stops and doesn't start again until I reload the page.

I just installed Ubuntu Netbook 10.10 on my new Asus Eee PC 1215T, and I'm having trouble getting Internet access. When I first start up or reboot the PC, I'll have network access, but not Internet access. I'm connecting via a WAN at my university, and so the first thing you have to do is "register" the computer on the network (by visiting a certain website on their intranet) before it will allow you to access the Internet. Takes about 3 minutes to register it. I have enough time to *begin* this registration process, but I've tried several times and I can't get all the way through it before I mysteriously lose all network access. Unfortunately this is a brand new machine and came without any OS installed, so there's no way I know of to test whether this is defective hardware or not.

I'm using Ubuntu 10.04 and after a recent software update, I found that my web browsers crash constantly. Firefox stays open for a few seconds and then dies and won't restart. Google Chrome keeps giving me the "Aw, Snap!" screen. Seamonkey and Epiphany run for a while and then crash. After some research, I uninstalled Flash, but that didn't change anything.On a possibly related note, I've been informed of disk errors during boot and prompted to fix them twice in the same two week period.

I have to type:/etc/init.d/networking restart and after that everything works just fine and I get internet again.Is there a way to automate that process on resuming from suspend, so that I won`t have to type it manually each time?

My computer starts up and, usually, gets to a desktop (I can login). If I click on a folder to open it, the computer just dies. No power at all. Sometimes it doesnt even make it through the boot up stage, just stopping before getting to grub. This happens in F10 and F13, whether the grub is on the harddrive or a USB key. I'm thinking that I might need a new power supply, but I'm also wondering if I might have fried the CPU, which ran for several days at 50 or so degrees, (for sensor one on the little gnome panel applet). But it did go over 60 a couple of times and die from overheating. These higher temperatures were achieved by running CPU intense software, with the cores in use running at 100% each. The higher temperatures were from running it with all four cores.

Suse 11.2 - KDE 4.3.5. I have only one sound card. The only Pulse software that is installed is libpulse0 and libxine1-pulse. All sound applications work. Amarok, vlc, kaffeine, Skype etc. But then every say 6th. or 7th. boot the sound dies. On everything. Even the startup melody. When I go to Yast>Hardware>Sound everything looks in order but the test on the card makes no sound. But if I delete the active card then re-enable it everything works again.
I saved the working /etc files as *.works and ran the following script...
The only difference was a slight volume difference in asound.state (23 vs 27).
I thought I might try to diagnose it by doing a file search for file changes in the last 5 minutes immediately after I run the Yast re-enable.
