• 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

• Why Ubuntu Server asks to insert a CD-ROM when installed from PXE?

  - by MainMa

  I set up a PXE server which hosts both Ubuntu Desktop and Ubuntu Server. Ubuntu Desktop is installed successfully from PXE. Ubuntu Server seems to successfully load vmlinuz and initrd.gz, asks for the language, then the location, then the keyboard layout, and finally complains that it can't mount the CD-ROM: The content of /var/lib/tftpboot/pxelinux.cfg/default is the following: default ubuntu-installer/amd64/boot-screens/vesamenu.c32 menu title Ubuntu setup label ubuntu-14.04-desktop-amd64 menu label ubuntu-14.04-desktop-amd64 kernel ubuntu-14.04-desktop-amd64/vmlinuz.efi append initrd=ubuntu-14.04-desktop-amd64/initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.1.41:/exports/ubuntu-14.04-desktop-amd64 splash -- label ubuntu-14.04-server-amd64 menu label ubuntu-14.04-server-amd64 kernel ubuntu-14.04-server-amd64/vmlinuz append initrd=ubuntu-14.04-server-amd64/initrd.gz root=/dev/nfs boot=install netboot=nfs nfsroot=192.168.1.41:/exports/ubuntu-14.04-server-amd64 splash -- What explains the fact that it requests the CD-ROM and how to avoid it?

• Nothing seems to be syncing with Ubuntu One

  - by Anthony Papillion

  So earlier tonight I set up Ubuntu One on a fresh install of Ubuntu 10.10. In my "Ubuntu One" directory, I created symbolic links to /Documents /Pictures and /Music. Right now, there is VERY little in those directories but what IS there isn't syncing at all. When I go to the Ubuntu One web interface, it tells me I'm using 0.00% of my storage space. When I try to view the files in the web interface, I am told 'Something has gone wrong' and I don't see anything. Can anyone help? Even my Tomboy notes aren't syncing! And yes, I am connected and the software says 'Synchronisation Complete' Thanks, Anthony

• Non-standard installation (installing Linux from Linux)

  - by Evan Plaice

  So, here's my setup. I have one partition with the newest version installed, a second partition with an older version installed (as a backup just in case), a swap partition that both share, and a boot partition so the bootloader doesn't need to be setup after each upgrade. Partitions: sda1 ext3 /boot sda2 ext4 / (current version) sda3 ext4 / (old version) sda4 swap /swap sda5 ntfs (contains folders symbolically linked to /home on /) So far it has been a very good setup. I can create new boot loaders without screwing it up and adding my personal files into a new install is as simple as creating some symbolic links (the partition is NTFS in case I need to load windows on the system again). Here's the issue. I'd like to be able to drop the install into /distro on the current version and install a new version on / on the old version effectively replacing/upgrading it. The goal is to be able to just swap out new versions as they are released while maintaining redundancy in case I don't like th update. So far I have: downloaded the install.iso created a folder in /distro copied the install.iso into /distro extracted vmlinuz and initrd.lz into /distro Then I modified /boot/grub/menu.lst with the following entry: title Install Linux root (hd0,1) kernel /distro/vmlinuz initrd /distro/initrd.lz vmlinuz loads perfectly but it says it can't find initrd.lz on boot. I have also tried to uncompress the image with: unlzma < initrd.lz > initrd.img And, updating the menu.lst file to match; but that doesn't work either. I'm assuming that vmlinuz (linux kernel) loads, fires up the virtual filesystem by creating a ramdisk (initrd), mounts the iso, and launches the installer. Am I missing something here? Update: First, I wanted to say that the accepted answer would have been the best option if I was doing a normal Ubuntu install. Unfortunately, I was installing Linux Mint (which lacks the script needed to make debootstrap work. So the problem I with the above approach was, I was missing the command that vmlinuz (linux kernel) needed to execute to start boot into LiveCD mode. By looking in the /boot/grub/grub.cfg file I found what I was missing. Although this method will work, it requires that the installation files reside on their own partition. I took the easy route and used unetbootin to drop the LiveCD on a usb drive and booted from that. Like I said before. Debootstrap would have been the ideal solution here. Even though I couldn't use it I wrote down the steps it would've taken to use it. Step One: Format sda3 (the partition with the old copy of linux that's being overwritten) I used gparted to format it as ext4 from within the current linux install. How this is done varies based on what tools you prefer to use. Step Two: Mount the newly formatted partition (we'll call the mount ubuntu for simplicity) sudo mkdir /mnt/ubuntu sudo mount -o -loop /dev/sda3 /mnt/ubuntu Step Three: Get debootstrap sudo apt-get install debootstrap Step Four: Mount the install disk (replace ubuntu.iso with the name if your install disk) sudo mkdir /media/cdrom sudo mount -o loop ~/ubuntu.iso /media/cdrom Step Five: Install the OS using debootstrap (replace fiesty with the version you're installing and amd64 with your processor's architecture) sudo debootstrap --arch amd64 fiesty /mnt/ubuntu file:/media/cdrom The settings here varies. While I loaded debootstrap using an install iso, you can also have debootstrap automatically download and install if with a repository link (While most of these repositories contain debian versions I'm still not clear as to whether Ubuntu has similar repositories). Here a list of the debian package repositories and their mirrors. This is how you'd deploy debootstrap if you were doing it directly from a repository: sudo debootstrap --arch amd64 squeeze /mnt/debian http://ftp.us.debian.org/debian Here's the link that I primarily used to figure this out.

• How to enable wireless on my hp compaq nx6110 laptop

  - by victor

  My laptop is an old HP Compaq NX6110. The wireless switch is not working, and I can`t also enable wireless from connexion manager. I connected to to the Internet with Ubuntu using wired LAN, and I downloaded windows wireless drivers, Wi-Fi radar application, and additional drivers. I also updated to Ubuntu 11.10 but still no luck. I guess I need some terminal commands. Any ideas are welcome. Thank you for the attention victor.

• Dash is slow and shows irrelevant results

  - by Alexey Frishman

  I currently have the latest Ubuntu 12.10 installed on my laptop. Usually I use Launchy application to have a quick access to any app/config/file etc. Now I'm trying to get used to Dash, which is supposed to be default way to do such things in recent Ubuntu versions. The difference between the usage of Launchy and Dash is following: Launchy: Alt+Space - Launchy shell shown instantly - type your request - open the target Dash: SuperKey - PERIOD - Dash is shown - type your request - PERIOD - navigate with arrow buttons between the results - open the desired result Another problem. When I type the term "ryth" (which is incorrectly spelled part of "Rhythmbox") what is shown in these 2 shells: Launchy: 1 result, which is Rhythmbox. The letters 'r', 'y', 't' and 'h' are highlighted. Dash: 2 results, which are MP3s from Amazon and are completely irrelevant to my request So is there any way to tweak the Dash to allow me to use it as I use Launchy with the same performance and results?

• Poor System performance on my machine running Ubuntu 12.04(Beta 2 updated to the present moment)

  - by Mohammad Kamil Nadeem

  Why is it that my system dies when multitasking(it is happening from 11.10) on Ubuntu11.10(Unity), Kubuntu 11.10(KDE) and Deepin Linux which is based on 11.10(Gnome-Shell) The thing is that I thought with 12.04 I would get performance like I used to get on 11.04 on which everything used to run fine without any lag or hiccups. The same lagging(Browser starts to stutter, increased delay in the launching of dash and applications)is happening on 12.04 http://i.imgur.com/YChKB.png and http://i.imgur.com/uyXLA.png . I believe that my system configuration is sufficient for running Ubuntu as you can check here http://paste.ubuntu.com/929734/ . I had the Google voice and chat plugin installed on 12.04 so someone suggested that I should remove that and see if the performance improves but no such respite(I am having this on multiple operating system based on Ubuntu 11.10 as I have mentioned above). On a friends suggestion Ran Memory Test through Partition Magic and my system passed that fine. One thing more that I would like to know is that why when I have 2Gb Ram and 2.1GB swap does my system starts lag and run poorly when Ram consumption goes 500+. If you require anymore information I will gladly provide it.

• Remove partition for failed installation

  - by kapitanluffy

  i tried installing ubuntu alongside windows 7 Installing Ubuntu alongside Windows and i failed so i decided to go with wubi again. after installing it, i noticed a separate hard disk. i investigated and found out that this hard disk is actually for the failed installation. i don't know where to find it inside the windows system. can anyone please teach me how to remove the 'failed' hard disk. here's a screenshot the left side is the current filesystem. the right side on the other hand is the 'failed' harddisk. i verified that it is the failed one because the wubi installation will provide a 'host' folder for the current partition it is currently installed. i tried looking for the 'failed' one using the windows' commandline but i don't know where to look for the 'failed' disk. (i used the cmd coz i don't want root.disk to mysteriously disappear again.) see http://ubuntu-with-wubi.blogspot.com/2011/01/mystery-of-disappearing-rootdisk.html

• How to setup Thinkpad features on Thinkpad T500

  - by gijoemike

  I have a IBM-Lenovo Thinkpad T500. I was previously a exclusive windows user, but recently installed ubuntu and loving it because of speed and interface. The only thing is that I don't get some features that I came to enjoy in windows. I need help setting these up: Hard-drive protection - active protection software that pauses drive when there is movement My printer doesn't work (can't find the driver for this one): canon Ip2600 A way to change which graphics chip to use while in OS. I have both the integrated and non integrated (dual-graphics). (If not easy to setup, I know there's a way to do it before it boots, but don't know how). CPU performance level - in windows you can pick "high performance", "power saver", etc.. to save batteries. My integrated camera w/light - it works but need an app where I can record videos, take snapshots, etc. can't find one that works. Thanks!

• Regardless of battery charge, when unplugged Ubuntu displays critical battery message and hibernates

  - by Chesc

  Regardless of battery charge, when unplugged Ubuntu displays critical battery message and hibernates. I can only seem to change it to either shutdown or hibernate. This does not happen when using windows 7 on the same computer. Windows 7 gives a good few hours on a full charge indicating that it is not a battery problem. Any help? I really don't want to have to use windows but its kinda pointless having a netbook that doesn't work when not plugged in! I'm using a toshiba nb250 and the most up to date 11.10 ubuntu distro. I use to get the critical battery message before on the previous ubuntu but it never shut down or hibernated my computer.

• Issues with ganglia and upstart in 13.04

  - by theist

  I'm having an issue with ganglia-monitor and upstart. Just after installing it starts and it cannot be stopped. I tried to solve it following http://upstart.ubuntu.com/cookbook/#expect but I can achieve upstart to track the actual pid of gmond. Assuming the configuration of the init config is wrong i followed direcetions in http://upstart.ubuntu.com/cookbook/#how-to-establish-fork-count in order to try to fix it. As it states a count of 1 means "exec fork" stanza and 2 means "exec daemon" .... gmond gives a count of 8... And of course I can get it to track the actual PID. I haven't found a bug report or something like that. Is there something I missed ? Upstart seems to be failing and the worst thing is that upstart hangs on start/stop and I cannot even uninstall or reconfigure packages.

• New games for 2011

  - by Oli

  I know there have been other questions like "What native games are available?" and they often have issues because they turn into a never-ending list of every game ever released for Linux. But I'd like to know what's coming out this year. Good answers can include: A game that's coming out in 2011 A Linux port being released for games that might be older (eg Trine) As much information and as many screenshots and links as possible Few old games unless they're doing a major update that changes the game very significantly. One game per answer, add as much information as possible and work with each other to build a catalogue of awesome things to look forward to this year.

• Is 1GB RAM with integrated graphics sufficient for Unity 3D on 12.04?

  - by Anwar Shah

  I have been using Ubuntu since Hardy Heron (8.04). I used Natty, Oneiric with Unity. But When I recently (more than 1 month now) upgraded My Ubuntu to Precise (12.04), the performance of my laptop is not satisfactory. It is too unresponsive compared to older releases. For example, the Unity in 12.04 is very unresponsive. Sometimes, it requires 2 seconds to show up the dash (which was not the case with Natty, though people always saying that Natty's version of Unity is buggiest). I am assuming that, May be my 1GB RAM now becomes too low to run Unity of Precise. But I also think, Since Unity is improved in Precise, It may not be the case. So, I am not sure. Do you have any ideas? Will upgrading RAM fix it? How much I need if upgrade is required? Laptop model: "Lenovo 3000 Y410" Graphic : "Intel GMA X3100" on Intel 965GM Chipset. RAM/Memory : "1 GB DDR2" (1 slot empty). Swap space : 1.1GB Resolution: 1280x800 widescreen Shared RAM for Graphics: 256 MB as below output suggests $ dmesg | grep AGP [ 0.825548] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000

• Window focus confusion in unity

  - by Bryan Agee

  I like having focus prevention set to high, so that I don't have some stupid auto-launched app steal my typing in the middle of something else. Unfortunately, Unity keeps focus on the right window while raising the new one. A number of times, this has caused me to close an application by accident that had control of the menu bar, even though it was underneath the new window. Is there a way to prevent raise without focus?

• Using GPU's RAM as RAMDISK

  - by user3476043

  I want to use my GPU's ram as a ramdisk, following these instructions : http://en.gentoo-wiki.com/wiki/Using_Graphics_Card_Memory_as_Swap But when I input the " modprobe phram phram=VRAM,0xd8400000,124Mi " command, I get the following error : modprobe: ERROR: could not insert 'phram': Input/output error I use Ubuntu Studio 14.04. Also, is there anyway I could use more than the 128M of prefetchable memory, my GPU has 1GB of ram, I would prefer to use "most" of it.

• Thunderbird uses the wrong browser

  - by Aaron Digulla

  I'm unable to make Thunderbird open the default browser. In the browser preferences, Chromium is selected as the default browser. It's also selected in "Default Applications" in System Settings. In Thunderbird, I read "Chrome (Default)" which is wrong on all levels: Chrome itself complains that it's not the default browser when I click a link inside Thunderbird. In all other places, that I could find, Chromium is the default Here is what I tried: I used update-alternatives --config x-www-browser to select chromium-browser as well (see How do I change the default browser?). And even when I select a different browser from the list in the Thunderbird preferences, it still opens Chrome. My current solution is to create a link from /usr/bin/google-chrome to chromium-browser. How can I force Thunderbird to use the browser I want??? EDIT I also updated gnome-www-browser (update-alternatives --config gnome-www-browser) after feedback from roadmr but that didn't help. At least sensible-browser opens Chromium, now, but Thunderbird is stubborn.

• How do I report a missing package dependency during an upgrade?

  - by crasic

  A friend of mine (somewhat new to linux) recently upgraded from 10.10 to 11.04 and his OS broke from the upgrade. A few minutes of troubleshooting showed that the culprit was the PAE kernel that the upgrade decided to install since it determined he had 4GB of phyisical RAM. More specifically the upgrade forgot to install the linux-headers-generic-pae required by the closed source nvidia drivers. I'm not entirely sure how to report this bug to the devs. Its an easy fix (after booting into the non-pae kernel and installing the package everything worked), but they are encouraging users to use the built-in bug reporting system and I'm not entirely certain how to report update bugs.
