• Reading cpu temperature Intel Celeron (R) with lm-sensors

  - by tim_a

  I know there are already a lot of questions like this, but non of the answers provided there could fix my problem. I try to read out my cpu temperature with lm-sensors on my ubuntu 10.04 LTS installation but I can't get to work. I did try the command sensors-detect several times but still nothing. My computer is an old PC with an Intel Celeron (R) @ 2.60 GHz. The odd thing is that the hdd temp is shown in the applet but when I type in the terminal sensors I get the error: "No sensors found! Make sure you loaded all the kernel drivers you need." I'm not really interested in the hdd temperature but I think it is strange that these sensors do work in the applet and not in the terminal. This is the output that sensors-detect gives: http://pastebin.com/F4hVKaLU Any suggestions?

• Ubuntu 12.04 - Wakes from Suspend by itself

  - by Peter

  This problem has only just started and I don't know what has changed to cause it. I suspend my ubuntu 12.04 PC and it used to stay asleep until I hit the enter key to wake it up but for the last week or so it's been waking itself up. I've checked the BIOS settings and all the Wake on Lan settings are Disabled. I've used the ethtool command and the wake on lan is set to "d" which I've read been off. Can anyone suggest anything?

• Package dependencies cannot be resloved?

  - by Hayden Win

  i was in the ubuntu software center, and when i try to install something like OpenJDK, i get an error saying: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. When i click on "Details" it shows this: The following packages have unmet dependencies: openjdk-6-jre: Depends: openjdk-6-jre-headless (>= 6b24-1.11.1-4ubuntu2) but 6b24-1.11.1-4ubuntu2 is to be installed Depends: libjpeg8 (>= 8c) but 8c-2ubuntu7 is to be installed Depends: libpulse0 (>= 1:0.99.1) but 1:1.1-0ubuntu15.2 is to be installed How do i fix this, and what's caused this problem in the first place?

• DHCP Fails To Start

  - by user209138

  I just installed Ubuntu 12.0.4 on an HP 8560 laptop. I installed Fog version 29 and everything worked just fine except the DHCP3 package failed to start. When I run the install command it says DHCP3 is installed, but when I type in the following command to start DHCP (sudo /etc/init.d/DHCP3-server start it says the command is not found. Is there a different command for Ubuntu 12? I have been using Ubuntu 10 on my other fog servers and that command works fine.Thank you for your help.

• Why does Ubuntu 13.10 not detect my Win7 partition?

  - by goutham

  I'm trying to install Ubuntu 13.10 alongside Windows 7 on my DELL INSPIRON 14z 5423 laptop and I'm new to all of this. I'm using the Ubuntu 13.10 64-bit ISO burned onto a CD. The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options: Erase disk and install Ubuntu (I don't want to do this) Encrypt new Ubuntu. Use LVM. Something else. If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of (500Gb), but that's not true because I have Windows 7. I restarted the laptop several times and booted the CD again and I got exactly the same as I did previously. How do fix this problem and install Ubuntu alongside Windows 7? After executing "sudo fdisk -l" command in terminal ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

• What Does Installing Ubuntu "Alongside" Windows Entail?

  - by Soft Skeleton

  I recently posted a question about an error I was receiving trying to access Ubuntu from the boot menu. I am using Windows 7 and Ubuntu 12.x (I THINK because I haven't accessed it in over a year due to being unable to run an important program for one of my classes on Ubuntu). On another laptop, I partitioned the hard drive and installed Windows and Ubuntu on the partitions. On this laptop, I simply installed Ubuntu from Windows, picking the option "alongside Windows", and didn't partition my hard drive manually. I was under the impression "alongside" entailed that Ubuntu would partition my hard drive, and that if I were to return my Windows partition to factory settings it would not affect the Ubuntu partition. However, given my current problem, I am wondering if I was mistaken in this assumption? When installing Ubuntu from Windows, selecting "alongside" Windows as the option from the Ubuntu installer, does that simply install Ubuntu within the Windows partition and thus returning it to factory settings would wipe out anything I had on the Ubuntu OS as well? Ubuntu is still in the boot menu as an option, but when I try to access it it says the drive is "corrupt" and wubi is mentioned in the error. I additionally tried to download a program ran from Windows to investigate partitions and there were no sign of my Ubuntu partition viewable from Windows. Is it possible Windows just can't see it? Any insight, corrections or answers is appreciated.

• Toshiba Tecra A8 display resizes to 4:3 when an External display is used

  - by Pete

  I am very new to this so please excuse me if the solution is simple. I am running an old Toshiba Tecra A8 laptop and the screen is fine until I attach an external monitor via VGA then the laptops monitor resizes itself and changes ratios to 3:4 is there a fix for this or am I out of luck? As additional information: I have tried 3 or 4 different monitors and it happens with all of them, except that the external monitors hold the 3:4 display ration but get stretched out. Feel free to add comments requesting more information if needed for a fix.

• Ubuntu always freezes on a friend's machine

  - by missingfaktor

  I am posting this on my friend's behalf. I installed Ubuntu 12.04 on my friend's computer but it continuously froze, no desktop effects worked, and it was frankly unusable. I thought this might be an issue with Unity and how it interacts with his hardware, so I tried several other desktop environments on his machine. These include KDE, Xfce, and GNOME. The problems persisted regardless of the desktop environment. I would like to note that he dual boots his system with Windows 7. Even there no desktop effects work but the system is reasonably stable. The following screenshots describe some of his system information (He is running Xfce at this time): 1: 2: Card information: intel corporation 82G33/G31 integrated graphics controller (rev02). What is the issue and how can it be solved? Please let me know if I should add any more information. Thank you.

• Windows Repairs Itself After Ubuntu Boot

  - by pjtatlow

  I have a custom built computer in my home which was running Windows 7 primarily. After I installed Ubuntu 12.04 and upgraded to 12.10, Windows 7 has to perform startup repair after every Ubuntu boot up. For example, I am using Ubuntu for my everyday work, but when I switch to Windows to play one of my steam games, windows fails to boot, and it switches to the recovery partition to "repair windows" then boots windows. The whole process takes about 20 minutes, which is quite annoying. Anyone know why this is happening or what I can do? Thanks in advance!

• Steam, launching Team Fortress 2: libGL.so.1: wrong ELF class: ELFCLASS64

  - by stefanhgm

  After I got Steam running with the workaround mentioned here, I've got nearly the same problem when launching Team Fortress 2. After starting it from Steam the "Launcher" pops up and after a few seconds it disappears with the following error in the terminal: /home/user/Steam/SteamApps/steamuser/Team Fortress 2/hl2_linux: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 Game removed: AppID 440 "Team Fortress 2", ProcID 5299 saving roaming config store to 'sharedconfig.vdf' roaming config store 2 saved successfully Because of the similarity with the workaround I used before, I tried to execute: export LD_LIBRARY_PATH=/usr/lib32:$LD_LIBRARY_PATH directly before launching the game, but there is no difference.

• Configuring mouse buttons

  - by Gilad Naaman

  I am using a HP NK527AA Wireless mouse with two side buttons. His mouse wheel is half broken: I can scroll but I can't click it. In windows I configured the side buttons as 3rd mouse button but unfortunately the only available drivers are for windows. Ubuntu treats the side-buttons as back\forward buttons and it's really annoying. Is there a way to configure the buttons if though the is no driver?

• Some info about SD card patitions after the use of the dd statment and some oiters doubts?

  - by AndreaNobili

  I am not very experienced using Linux and I have the following situation that cause me some doubts. I have wrote RaspBian (the RaspBerry linux distribution) on an SD card using Ubuntu dd statment: sudo dd if=2014-01-07-wheezy-raspbian.img of=/dev/sdb bs=1024 So if now I perform the fdisk -l statment I obtain that I have 2 partitions related to my SD card, that are the followins: Dispositivo Boot Start End Blocks Id System /dev/sdb1 8192 122879 57344 c W95 FAT32 (LBA) /dev/sdb2 122880 5785599 2831360 83 Linux And now the first doubt: the dd statment create on the SD card two partitions: 1) /dev/sdb1 that is a litle FAT32 partition (what it means (LBA)?) 2) /dev/sdb2 that is a larger Linux ext3 partition Ok...the doubt is: why it also create to me a FAT32 partition and not only a Linux ext3 partition? Ok...if I go into my computer resource I can see a device (related to my SD card) into the devices list that contains some RaspBian file, following a screenshot: And if I see the property of this device I obtain this: So, looking at the previous screenshot it seems to me that this is the small FAT32 partition, and now I have the followings doubts: If it is the smallest FAT32 partition, what contains? The RaspBian boot or what? Why, in the devices list, I have only the FAT32 partition and not also the Linux one (/dev/sdb2), to see it have I to mount it? how? Tnx

• Error installing Package Control for Sublime Text 3 on Ubuntu 14.04

  - by user1837378

  This is the error. It comes up when I paste and enter the installation code (which I get from the Package Control website) and each time I open up Sublime Text. Package Control Your system's locale is set to a value that can not handle non-ASCII characters. Package Control can not properly work unless this is fixed. On Linux, please reference your distribution's docs for information on properly setting the LANG environmental variable. As a temporary work-around, you can launch Sublime Text from the terminal with: LANG=en_US.UTF-8 sublime_text I had the same problem with Ubuntu 13.04 so it's probably not version-dependent.

  The old-releases.ubuntu.com mirror hosts the repositories for EOL Ubuntu releases. The main page currently lists up to 11.10 (or 12.04.3 if you count point upgrades), but the dists page lists up to 13.04. Why the discrepancy? When will the main page be updated? When will the newest EOL release (13.10) be shifted here? I'd like documentation backing up answers, please.

• Indicator applet-less applications?

  - by armornick

  Since I heard that indicator applets are going to replace the notification area, I wondered what was going to happen to applications that use the notification area and don't have an indicator applet? Is the Ubuntu team going to write an indicator applet for every application out there? You can't expect the developers of applications to add that Ubuntu-only task to their list. Don't get me wrong, I love the indicator applets. But I'm a little concerned about this.

• Problem with wake after suspend using USB remote.

  - by Bod

  Hi, I'm a linux newbie looking for some help. I'm currently setting up an XBMC HTPC using a laptop and 10.10 and all works great except for waking from resume using the power button on the remote. The suspend works from remote works fine as does the resume using the power button on the laptop. I've checked /proc/acpi/wakeup which initially showed the following. Device S-state Status Sysfs node C096 S5 *disabled pci:0000:00:1e.0 C0F1 S3 *disabled pci:0000:00:1d.0 C0F8 S3 *disabled pci:0000:00:1d.1 C0F9 S3 *disabled pci:0000:00:1d.2 C0FA S3 *disabled pci:0000:00:1d.3 C0FB S3 *disabled pci:0000:00:1d.7 C102 S5 *disabled pci:0000:00:1c.0 C22B S5 *disabled pci:0000:08:00.0 C115 S5 *disabled pci:0000:00:1c.2 C22C S5 *disabled C118 S5 *disabled pci:0000:00:1c.3 C22C S5 *disabled I've since configured the above so that the S3 devices above are enabled.

It simply refuses to wakeup from the remote. The USB receiver shows no activity LED while suspended. Suspend/resume from the remote works fine from Windows 7 so I know the laptop is ok with it. Any ideas? I need to get this sorted to gain Wife Approval for this system. Thanks, Bod.

• Automatically adding CD box art so that I can put it on my iPod.

  - by Seamus

  I know it's possible to automatically find CD covers for albums, because rhythmbox is doing it on the fly. (When I listen to stuff, it finds the CD cover online...) What I want is to get this information onto my ipod. As it stands pretty much all my songs have the default blank CD cover... I use gtkpod to transfer music to it. This needs to be an automatic process, because I have a large music library and I'm lazy and it's not exactly an important thing... I rip CDs I buy with the basic CD extractor, so all the files are in a Artist/Album/song.mp3 structure. (Yes I know, mp3 is evil, but iPod doesn't like .ogg so whatever)

• How to make/use launcher?

  - by prosseek

  In ubuntu, I can run firefox with the command firefox in Terminal, or click the button in dock or panel. How does this possible with ubuntu? I googled to find the name launcher, but I don't know exactly how does it work. Q1 : How to make launcher? If I make a GUI program, does that mean that I need to create launcher to start by clicking it? Q2 : Can I make a launcher for whatever program, even if it's not a GUI program? Q3 : How to link a launcher? How can make a link to a launcher in a Desktop to start a program? Q4 : The idea of launcher is unique to ubuntu? Or if I have one launcher, can I use it for other distributions? Q5 : Why some of the program pops up its icon in Docky (firefox for example), but some of the program doesn't (p4v for example) ?

• Display current layout (language code/country flag) in keyboard indicator

  - by Jono

  Just upgraded from 10.04 to 10.10, and the keyboard indicator applet no longer displays the two-letter country code for the active layout. This is terrible. Is this the default behaviour? Anyone using two layouts can't tell which language they're in. I can't seem to find the setting for this, it used to be in the preferences for keyboard layout. Update 1: In case this wasn't obvious - I have two keyboard layouts - English and Hebrew. I just upgraded form 10.04, where the country code (USA/IL) was displayed, overlaid on the flag. Now all I get is a vague keyboard icon, and can't find the settings for this. Update 2: this seems to be a bug that people have been reporting since Lucid, and is now back in Maverick
