• HDMI Sound Stops Working

  - by stueng

  When not used for a few hours the sound stops working on my HTPC. To get sound to work again I have to unplug the HDMI cable and plug it back in again When this sound "outage" occurs, the HDMI device dissapears from the sound config output devices I see the following in dmesg [78534.010328] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78534.010363] HDMI status: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78558.948403] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78558.948429] HDMI status: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78562.579047] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=0 [78562.579078] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78562.579992] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=1 [78562.580043] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78562.876030] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78563.176036] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78563.195139] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78563.195169] HDMI status: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78563.476030] HDMI status: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78635.529493] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78635.529524] HDMI status: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=0 [78641.330701] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=0 [78641.330733] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78641.331649] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=1 [78641.331668] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78641.628050] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78641.928037] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78642.228042] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78642.528039] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [78642.828037] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1

• intermittent DNS problems

  - by jemminger

  How would I go about tracking this issue down? One of my websites has been up for years without issue. We're using Godaddy's nameservers for our domain. Lately in the past two weeks, I've noticed that once from home on my Cox cable connection, I could not connect to the site... it said the domain could not be resolved. I checked downforeveryoneorjustme.com, and it said it was fine. The "outage" lasted maybe five minutes (through a reboot too, and I'm on a mac FWIW) and then it started working again. Then it happened again this week, but from our office on a different Cox connection. Then it happened again from the office, but for a different domain. I called Cox during one outage, and the tech there could resolve the domain without a problem. When these outages are occurring, I can issue "host mydomain.com" and get "domain not found", but using "host mydomain.com 8.8.8.8" will resolve normally. Where do I start? We're getting reports now that our customers are experiencing it too.

• Hardening network with sysctl settings made Wi-fi downloading speed extremely slow

  - by Rohit Bansal

  I just followed up following steps to harden network security The /etc/sysctl.conf file contain all the sysctl settings. Prevent source routing of incoming packets and log malformed IP's enter the following in a terminal window: sudo vi /etc/sysctl.conf Edit the `/etc/sysctl.conf` file and un-comment or add the following lines : # IP Spoofing protection net.ipv4.conf.all.rp_filter = 1 net.ipv4.conf.default.rp_filter = 1 # Ignore ICMP broadcast requests net.ipv4.icmp_echo_ignore_broadcasts = 1 # Disable source packet routing net.ipv4.conf.all.accept_source_route = 0 net.ipv6.conf.all.accept_source_route = 0 net.ipv4.conf.default.accept_source_route = 0 net.ipv6.conf.default.accept_source_route = 0 # Ignore send redirects net.ipv4.conf.all.send_redirects = 0 net.ipv4.conf.default.send_redirects = 0 # Block SYN attacks net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_max_syn_backlog = 2048 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 5 # Log Martians net.ipv4.conf.all.log_martians = 1 net.ipv4.icmp_ignore_bogus_error_responses = 1 # Ignore ICMP redirects net.ipv4.conf.all.accept_redirects = 0 net.ipv6.conf.all.accept_redirects = 0 net.ipv4.conf.default.accept_redirects = 0 net.ipv6.conf.default.accept_redirects = 0 # Ignore Directed pings net.ipv4.icmp_echo_ignore_all = 1 To reload sysctl with the latest changes, enter: sudo sysctl -p But, after applying the changes I found "Wi-fi" downloading speed and terminal downloading speed extremely slow (less than 1KB/s) however surfing speed through browser was good. But, using direct ethernet cable was giving a good speed. Then, I reverted back the above changes and things fall back in line once again.... Could you please let me know what possibly in above script is affecting such behaviour [and why] ? How could I still maintain hardening of network security without disturbing Wi-fi downloading speed ?

• Internet suddenly stopped working

  - by user95629

  I was using NoMachine to access Ubuntu 11.10 when suddenly the internet on Ubuntu stopped working. Now Ubuntu doesn't recognize the internet at all (including locally). Symptoms: Doesn't recognize the fact that there is an ethernet cable attached. (I've tried switching cables, didn't work.) GUI says "No network devices available" Can't ping external IP addresses. Tried changing /etc/network/interfaces to eth1 instead of eth0 but it didn't work. ifconfig provides no output relating to eth0. When I type "/etc/init.d/networking restart" it tells me "Cannot find device 'eth0'/Failed to bring up eth0." The network settings had used a static IP address prior to the crash. I don't know why it won't recognize the ethernet (I think this is the fundamental problem, but I might be wrong) and why it stopped working so suddenly--I haven't installed any updates lately. Any ideas? Any more information I should provide? EDIT: lspci recognizes the Ethernet controller; netstat does not. lspci calls it "Intel Corporation Device 0000"

• How to speed up file transfer to/from Ubuntu Server 11.10 (wifi)

  - by Alexander

  I've been searching AU & elsewhere for the last day and a half. Haven't found an answer so I joined AU to ask for help. I'm hoping someone can point me in the right direction. Ubuntu Server 11.10 Samba VSFTPD Windows 7 PC 2 MacBook Pro - Snow Leopard/Lion 1 iMac - Lion Wireless LAN using DLink DIR-655 Link Speed: 195 Mbit/s on Mac - 54Mbps on Windows ISP Connection: Cable - 20 down/3 up No Domain Controller. All machines are members of the same workgroup. No matter how I connect I can't get better than about 700K transfer rate up/down. Mac/PC, SMB/ftp, Domain Name/Local IP I've tried different user accounts and using different folders, different volumes on the server. Nothing seems to make a difference. 700K up/down. Period. Any suggestions would be greatly appreciated. Thanks, Alexander EDIT: Using sftp now and uploading seems to peak at 980k. After about 5 minutes into a 650MB file, downloading is at 1072k and climbing about 500b/s every ten seconds. If any of that matters... I was expecting a lot faster than 1Mb tx rate. Am I off base here? EDIT: From all I've read so far, perhaps the speed isn't that bad. I only installed Ubuntu out of boredom this past weekend. The trouble is, I like it. Guess it's time to ditch the wifi and run some Cat 5.

• [MINI HOW-TO] Update Your Zune Player Software

  - by Mysticgeek

  Keeping your computer and software up to date is very important in keeping everything running smooth and secure. It’s also important to keep your geeky gadgets updated as well. Here we take a look at updating a Zune HD. Note: In this example we’re updating a Zune HD out of the box which hasn’t been updated yet. The first thing you’ll need to do if you haven’t already is download and install the latest Zune software (link below). Now plug your Zune into your computer with the included USB connection cable and give it a moment to be recognized. Next launch the Zune Desktop software and you should get the following screen. Just accept the EULA… Then the update kicks off. Make sure not to disconnect the Zune while the update takes place. The update will take a few minutes, and after it’s complete you should be good to go and can start using your Zune. To update your player in the future, go to General Settings then Player Update. Just like your computer’s hardware and software, you want to keep your other geeky gadgets updated as well. This will help the device run more smoothly, and sometimes add additional functionality.

• What is "Open" anyway?

  - by EmbeddedInsider

  This terms is often used with many meanings.  For example, some people consider Flash 'open' and 'multi-platform' .  But Flash is a product of Adobe systems, locked down, copy protected and distribution restricted.  And versions for other than standard PC, home use, may carry licence fees. Check it out: 3.1 Adobe Runtime Restrictions. You will not use any Adobe Runtime on any non-PC device or with any embedded or device version of any operating system. For the avoidance of doubt, and by example only, you may not use an Adobe Runtime on any (a) mobile device, set top box (STB), handheld, phone, web pad, tablet and Tablet PC (other than with Windows XP Tablet PC Edition and its successors), game console, TV, DVD player, media center (other than with Windows XP Media Center Edition and its successors), electronic billboard or other digital signage, Internet appliance or other Internet-connected device, PDA, medical device, ATM, telematic device, gaming machine, home automation system, kiosk, remote control device, or any other consumer electronics device, (b) operator-based mobile, cable, satellite, or television system or (c) other closed system device. For information on licensing Adobe Runtimes for use on such systems please visit http://www.adobe.com/go/licensing.

• hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

  - by Jim LastName

  I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

• A bounce-rate attack to manipulate SEO ?

  - by Denis Volovik

  This is a question to experienced people that might help us shed some light on the issue. We noticed a very strange behavior on our site, in Google Analytics. Some dude from Finland, namely, from Kouvola city is hitting one of our pages - only one page on our site, 'bout a hundred times per day, all with an average bounce rate of 90%+... This is causing our overall bounce rate to go up by 1 to 3% per day... which is very disturbing.. since we're trying to do our best in order to keep it as low as possible. And obviously having it jumped from ~24% to 27%, just because of that crazy dude is not making us happy at all... We tried implementing a geo-targeted script in order to catch this particular visitor and deliver him a juicy message, and it seemed like it helped in the beginning, it has stopped for a day or two, but now he's back... The geo-targeted script was also logging all IP addresses for page requests originating from Finland in order to find out more details and (in order to block them on the server level, later).. but thing is, it was all mainly cable or DSL connections with various, but not constantly repeating IPs... we are all wondering what is he up to really ? I think that this page should be kept updated with ideas on how to combat this and perhaps someone could also shed light on what it might be ? What is the reason for doing this "bounce-rate attack", as I call it? There was a similar question asked on stackoverflow earlier, with no meaningful answer - here - How to stop bounce rate manipulation.

• The Other "C" in CRM

  - by [email protected]

  By Brian Dayton on April 5, 2010 7:04 PM Folks who know me know that I rarely, if ever, talk politics. And I never talk politicians. Having grown up in a household with one parent leaning left and the other leaning to the right it was the best way to keep the peace. This isn't about politics. It's about "constituents" and the need to improve the services and service levels for people--at the city, county, state/province, etc. level all the way up to national governments. As a citizen and tax payer it's also important to me that these services be provided at a reasonable cost. If there's a better and more efficient way to do something then it's my hope that a public sector organization takes advantage of technology the same way private sector companies do. Social services organizations have a complex job. They provide the services that people need, from healthcare and children's assistance to helping people find jobs. But many of these organizations are still managing these processes manually or outdated, home-grown applications that could have been written up to 30 years ago. A lot has changed in technology. On the (this is as political as I'm going to get) political front, stakeholders like you and me are expecting greater transparency on where and how funds are spent. I'll admit that most of the time, when I think about CRM systems, I think about my experience as a customer of my bank, utilities company or cable operator. But now that I'm older, have children and a house--I find myself interacting more and more with agencies and services organizations. My experiences are sometimes good and sometimes not so good. Along those lines, last week's announcement of Siebel CRM 8.2 for Public Sector caught my eye. You may not work in the public sector, but you are a constituent of some--actually a lot--of public sector organizations. I don't know which CRM systems city and county utilize but I'm going to start paying closer attention.

• Suspending my laptop breaks ethernet over firewire, are there commands which can fix it?

  - by Josh

  As mentioned in this question I am using a firewire cable to provide a private network between my laptop and my desktop, because it makes using the screen sharing program synergy much nicer than using WIFI. However when I leave my office for the day and I suspend my laptop, when I return the next day, the desktop and the laptop cannot communicate over firewire anymore. The firewire0 device still has an IP address. but when I try and ping the desktop I get no route to host I'm using kernel 2.6.35-24-generic #42-Ubuntu SMP x86_64 on Ubuntu 10.10. Is there some way I can remedy this without a reboot? Like, removing some kernel modules and re-inserting them? Here's what I have tried so far and the results: root@token:~# dmesg|tail -n 1 [592525.204024] firewire_core: phy config: card 0, new root=ffc1, gap_count=5 root@token:~# modprobe -r firewire_net firewire_ohci firewire_core root@token:~# modprobe -v firewire_ohci insmod /lib/modules/2.6.35-24-generic/kernel/lib/crc-itu-t.ko insmod /lib/modules/2.6.35-24-generic/kernel/drivers/firewire/firewire-core.ko insmod /lib/modules/2.6.35-24-generic/kernel/drivers/firewire/firewire-ohci.ko root@token:~# dmesg|tail [592525.204024] firewire_core: phy config: card 0, new root=ffc1, gap_count=5 [592563.410868] firewire_ohci: Removed fw-ohci device.

• Ubuntu 12.04 LTS , Dell d410 output to External Monitor/TV with docking

  - by Gck

  I am not able to see the video output on My external monitor/TV after installing 12.04 LTS. I had the same issue with 11 versions also. This issue does not happen on 10.04 LTS version. This is my setup. Dell latitude D410 with Intel Mobile 915 GM/910GML express controller using the Dell docking station Connecting to my 42inch TV with DVI (from Docking) to HDMI cable (on TV) If i close the lid, some times i am able to see the video output on TV, but the resolution is making the fonts so small, i cannot even see it and when i click displays option to change the resolution, the output goes off completely and it is shown now on the laptop screen. one time, i got the output on both the screens, but i am not able to replicate that scenario even after trying the Fn+F8 key option on my laptop. earlier some time back when i ran version 11.x ubuntu, i was able to get the output on both the screens (basically mirrored output) with large font resolution on my TV using the monitor Test tool as mentioned here :http://www.bigfatostrich.com/2011/05/solved-ubuntu-11-04-broken-external-display/ The problem with this approach is that i have to do it every time i restart the machine and more over the video output is present on both the screens (mirrored), which is of no use. As i stated before, this does not happen with 10.04 LTS. With 10.04 LTS my laptop screen is off automatically and the output is seen on TV/external display. Can anyone share any options that i can try? How can we achieve the behavior of 10.04 LTS with respect to the External display on 12.04 LTS . Thankyou very much for your help in advance.

• SMART Status Data Interpretation - Disk Utility

  - by Mah

  Last week my external harddisk (Seagate Barracuda 1.5TB in a custom enclosure) showed signs of failure (Disk Utility SMART Pre-failure status - several bad sectors) and I decided to change it. I bought a new HDD (Seagate Barracuda 2TB) and connected it to my Ubuntu box with a SATA to USB cable that could not report SMART status. I copied all the contents of the old HDD to the new HDD (one partition with rsync, the other with parted cp) and then gently replaced the old HDD with the new one inside my aluminum enclosure. For obscure reasons after reconnecting the new HDD through the old enclosure, the Linux box could not detect my partitions. I recovered the partitions with testdisk and restarted the computer. After the restart I checked the SMART status of the new HDD an I get this: Read Error Rate --------------- Normalized 108 Worst 99 Threshold 6 Value 16737944 I got a high value on the Seek Error Rate as well. Wondering why this happens I copied 2 GB directory from one partition to the other and rechecked the SMART status (5 minutes later). This time I got the following: Read Error Rate --------------- Normalized 109 Worst 99 Threshold 6 Value 24792504 As you see there has been an increase in the error rate. I am unable to interpret these numbers. Is my new hard disk already dying? What are the acceptable values in these fields for Seagate hard disks? Then why the assessment is still good? While I could get temperature and airflow temperature data from my old HDD, I can not fetch them for the new one. I noticed that my old hdd had got really hot sometimes. Is it possible that the enclosure is killing the harddisks due to high temperature?... Thanks

• What would cause SSD to become not detectable?

  - by Balthazar

  I recently purchased an Intel 520 120GB SSD and installed Ubuntu on it. Occasionally my system will freeze and I will have to ALT-PRINT SCREEN-REISUB to reboot. Sometimes it will reboot and work just fine. Other times it just hangs at a flashing prompt. If I boot from a Live USB I can run Boot-Repair and it will usually reboot fine the next go round. I have noticed today that when I am running the live USB and open Nautilus my SSD partitions will sporadically disappear and reappear. Even if they are mounted. I was thinking it was a poor connection, but I have tried a different SATA cable and a different SATA port. Is it possible I have a faulty SSD, or is there something different you have to do with SSDs to make sure they stay mounted (I was thinking like it has some sort of goofy power savings feature that needs to be disabled). I found the place in the bios where the SATA ports are listed. They are all set to AHCI(Chipset - SATA Mode = AHCI) The unmounting/remounting happens all the time. I think this is the relevant part of the syslog: http://pastebin.com/WxHdRAAq

Let me know if you need any more information. :)

• make my Ubuntu 12.04 laptop visible on the network

  - by Andrew Boyd

  I'm ecstatically happy with my 12.04 on my laptop after loading it over my MS Vista... but there's just one thing, one little fly in the ointment.... While I can view our 2 Terabyte, shared hard-drive in the lounge (and copy files back and forth) I can't see my PC (when I boot up in Ubuntu 12.04) nor the Lubuntu computer connected to the TV (for movies, Youtube etc). Printing to the HP office jet on the PC doesnt work over the network either. Have had one dubious flirtation with Samba, which seems to be the only thing I've found that will 'work', however halfway through that "installation" everything just ground to a halt, the directions began to stop making sense... I was working from this page. Our Network consists of the following: Our Internet service is wirelessly sent to us from our provider to our dish on a pole. It comes into the house via an ethernet cable. We split it there to a phone, and to 6 other destinations (bedrooms, computers, and to another splitter in the lounge which has a wifi antennae and 4 ethernet ports). one port goes to the Lubuntu OS PC which is connected to the TV the second port goes to the 2 Terabyte harddrive (MS powered 'Mybooklive') (the other two are empty) My Ubuntu 12.04 laptop connects wirelessly to this splitter in the lounge. I know just enough about computers to get myself into an awful mess without too much trouble We usually can view friends' laptops when they get on our network (as they are invariably MS OS's) Our flatmate, who introduced us to Linux's computer is also invisible How can we make our Linux OS based computers visible on the network and share files and printing?

• /etc/resolv.conf nameserver fd00::1

  - by user88631

  My /etc/resolv.conf constantly get a mysterious entry, i run a home network with ipv6 provided by ravd, the interface is auto-configured by Network manager (all name server lookups are lost when this line is first in my /etc/resolv.conf) . Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) **# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN** nameserver fd00::1 nameserver 192.168.1.1 search home.int When ping is working cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 192.168.1.1 search home.int So something is putting fd00::1 at start of file, not if I ping6 fd00::1 I get Destination unreachable: Administratively prohibited To diagnose this I ran the router with single cable to connected to ubuntu machine. Ran tcpdump + restarted network on ubuntu. "tcpdump ip6 -e -i eth0 | grep fd00" finds nothing, it's not being advertised via the network.. The only hit I got was when an upstream router refused a connection attempt from the ubuntu machine to fd00::1. I have also switched on debug for network manager & it appears to set the mystery line.. 15:22:14 storage-pc NetworkManager[349]: <info> Activation (eth0) Stage 5 of 5 (IPv4 Commit) complete. 15:22:14 storage-pc NetworkManager[349]: <warn> dnsmasq exited with error: Other problem (5) 15:22:14 storage-pc NetworkManager[349]: <debug> [1346822534.281528] [nm-dns-manager.c:598] update_dns(): updating resolv.conf 15:22:14 storage-pc NetworkManager[349]: <debug> [1346822534.281875] [nm-dns-manager.c:719] update_dns(): DNS: plugin dnsmasq ignored (caching disabled) 15:22:14 storage-pc NetworkManager[349]: <info> ((null)): writing resolv.conf to /sbin/resolvconf 15:22:14 storage-pc dbus[2184]: [system] Successfully activated service 'org.freedesktop.nm_dispatcher' 15:22:14 storage-pc dnsmasq[2875]: reading /etc/resolv.conf 15:22:14 storage-pc dnsmasq[2875]: using nameserver 192.168.1.1#53 15:22:14 storage-pc dnsmasq[2875]: using nameserver fd00::1#53 Any suggestions on how to find out where this comes from?

• apt-get update very slow, stuck at "Waiting for headers"

  - by Liam

  I have looked at similar questions: Stuck at 0% [waiting for headers] (apt) apt-get update stuck on "Waiting for Headers" However neither one of them answer my problem. I am running 12.04 AMD64 and have recently started getting an issue that when I update my repos from my connection at home through a terminal, using sudo apt-get update, it takes forever (literally after 2 hours it was at 28%), however when I run from a different location it takes less than 5 minutes to complete. I have attempted changing which mirror I use but that does not solve the issue. I have also cut down what is in my sources list but this also makes no difference. There are no faults on my ADSL line as I have already contacted my ISP to check this. It also makes no difference if I use a WiFi or network cable connection. What could be my issue? A speed test (www.speedtest.net) comes out at about 0.9 Mbps down and 0.42 Mbps up (which is a shade under the advertised line speed), I reside in South Africa and use the UCT LEG server. But I have also tried the other mirrors available in SA....none of them make a difference.

• forcing upgrade or how to upgrade packages after update failed

  - by Orosjopie

  How do I continue upgrade or fix upgrade as upgrading in 13.04 to 13.10 failed. I'm currently running terminal in restore mode. I get the error unmet dependencies, but tried to install apt-get -f install, but get this error: unable to fetch some archives. using apt-get update also brings errors for example: failed to fetch http: archive.canonical.com/ubuntu/dists/quantal/release.gpg Could not resolve 'archive.canonical.com. Is it my internet connection? Its currently connected via a network cable and internet is on other computers. If internet on my ubuntu 13.10, how do I switch it on? or how can fix my upgrade problem that I can boot ubuntu normal, backup, then format and reload ubuntu 13.10 properly? I posted this problem that has also linked to this problem I mentioned: upgrading to ubuntu 13.10 failed/crashed. I did manager to install/upgrade some of the files and got ubuntu 13.10 to reboot, but not 100%, as it is slow and the unity desktop is not showing 100%. in trying some of the commands online, I get the error that the activity manager is not installed, when trying to install it, it conflicts with activity-log-manager-common. Please assist.

• Why does Ubuntu keep trying to connect to a WiFi network while plugged into an ethernet

  - by labarna

  My desk is situated at the edge of the range of a wireless signal which I use occasionally (when away from my desk) and is therefore saved in network manager. At my desk, however, I plug into the ethernet cable. While I'm working the computer is constantly trying to join the wireless network and usually failing this results in two annoying behaviors. 1: In gnome shell the network connect and disconnect notices keep popping up at the bottom of the screen and I have to click them to make them disappear (I assume it's been fixed in the next version of gnome). 2: (the worst!) Occasionally the wifi password dialog will pop up and ask for the password to this network (which is already saved). An additionally annoyance is that in gnome shell I'll get two copies of the dialog that I have to cancel, one is gnome shell themed (no window border etc...) and the other is just normal gnome themed. (Sometimes if I've been away from the computer for a while I will have multiple copies of this dialog up as its been trying to connect for a while resulting in at times 20 dialogs to cancel). Note, all the while I've been happily connected to the ethernet and have full network access. This is incredibly annoying and distracting, why doesn't ubuntu stop trying to connect to wifi if I'm on the ethernet (unless I want to broadcast my own network, but that's different)?

• How do I get OBDII software working?

  - by NoBugs

  I have an ODBII USB cable for vehicle diagnostics, unfortunately I haven't been able to get it working on Ubuntu 12.04. The closest I've come is using the VAG-COM software with wine, using the ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 trick and running stty -F /dev/ttyUSB0 speed 9600 repeatedly. It will connect and show the vehicle is OBDII, but none of the useful features seem to be working. I tried: Scantool - says it's connecting to the /dev/device in terminal, but doesn't. obdgpslogger - times out all the time. pyobd - This seems to be the most up-to-date source I could find, I had to adjust the code a bit to work (see here for changes). Still, in obd_io.py interpret_result function, it says it's looking for 4 space separated numbers, where the usb-serial is receiving bogus code "0100" instead? The device shows up in lsusb as: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Is the problem that these native tools don't expect a USB serial, or a serial of this type? Or are these apps too old to recognize OBD2 of this vehicle?

• How to make pulseaudio and ubuntu detect the same audio device as alsa driver

  - by Kiwy

  I use Ubuntu 14.04 x64 and I use gnome-shell on my laptop. I have a Bose companion 5 (which is basically a USB sound system) and a HDMI port, both does work perfectly when I just boot with the cable plugin. However, when my laptop go to sleep or get unplugged from those two outputs, if I plug back the device, I end up without any hardware detection (only the built-in speakers) from pulse and gnome-shell sound output selector while if I use alsamixer, the device look up and ready. gstreamer-properties allow me to select and test effectively any device but while alsa recognize any device on the run, pulse is not capable of handling things correctly, my question is then: How can I make pulse detect and use the same hardware as alsa, or how to remove completely and gracefully pulseaudio (meaning volume applet running in gnome shell) I don't mind if the project implies to recompile half gnome shell if it implies those audio outputs work all the time. Pulse does not list my soundcard when I use command pactl list cards while the module plug&play for sound card is loaded in pactl list modules. I really don't know what to do, the behavior seems pretty random.

• Managing Kindle Fire with on 12.04 via Micro-USB

  - by pirtle

  To begin, I have read both Is there a way to get a Kindle Fire to work with 12.04? and How can I transfer files to a Kindle Fire with a Micro-USB cable? My problem is that I am unable to mount my Kindle Fire in order to add books to it. I have installed calibre, but it is unable to manage any devices until the computer itself has recognized it. The latter post had an excellent answer (provided by @jeremiah) that was making some progress. Unfortunately, I think I don't know enough about the -t flag used with mount. This is what I've done... Ran dmesg to locate the device: [ 3.920886] sd 6:0:0:0: [sdb] Attached SCSI removable disk Confirmed it's location: $ sudo ls -l /dev/disk/by-id lrwxrwxrwx 1 root root 9 Aug 18 15:52 usb-Amazon_Kindle_3C6C002600000001-0:0 -> ../../sdb So we know that my Kindle is recognized on /dev/sdb. I then used the mount command suggested by @jeremiah: $ sudo mount -t ext3 /dev/sdb/ /mnt/kindle/ mount: no medium found on /dev/sdb The same error occurs for sudo mount /dev/sdb /mnt/kindle. Note: I have created the 'kindle' directory in 'mnt' Any suggestions?
