• Windows XP guest in Ubuntu VirtualBox OSE VM does not install driver to use host's HP laptop webcam.

  - by Guillermo Torres

  I recently created a virtual windows xp with Virtual Box OSE. The sound and video seem to be working just fine. However, it does not recognize the webcam which I use to video chat with yahoo messenger. I use Windows to have video chats with my daughters who live in another country. Since I did not want to go back to windows, I decided to try installing windows in a virtual machine. But when I tried using it yesterday, everything worked perfectly except for the webcam. I was not able to make the webcam work. I tried to download the drivers for it, but since my laptop is HP Pavilion g4-1287la, Core i3, none of the drivers I tried worked. I got the same error every time I tried to install them, something like: This driver cannot be installed in this machine

• Dell xps 15z fan issue in ubuntu 12.04

  - by Paxinum

  I just updated to ubuntu 12.04 on my Dell laptop xps 15z. The trouble is that I hear a slight ticking sound every 3rd second, probably from a fan. This is a new issue in this ubuntu version. I use the recommended boot options for grub, i.e. acpi_backlight=vendor, but I do not use any acpi=off or acpi=noirq. Is there a way to fix this issue from ubuntu, by maybe controlling the fans somehow? EDIT: Notice, the sound goes away as the fan speeds up, (when doing calculations or such), so it is really a fan issue. EDIT2: I have located the issue: If I use conky 1.9, together with the command execpi for a python application, then the sound appears, and the noise syncs with the update interval for conky (NOT for the update interval for execpi!). The noise seems to be proportional to the complexity of the drawing that is needed. This is very strange, as this issue was not in the prev. version of conky I used. The solution was to increase the update interval for conky from 0.5 to 3, i.e. update every 3rd second instead of twice a second.

• How can I remove packages using preseed?

  - by Jorge Castro

  I'm setting up an automated "no questions asked" preseed system and using Dustin Kirkland's server preseed as an example. He uses the following line to install three packages as part of the automated install: d-i pkgsel/include string byobu vim openssh-server I am looking for the inverse of this, basically be able to remove packages as part of the automated install. I've checked the Installation Guide I've checked this example preseed, but it's not clear if this is the canonical list of every single option available. I am thinking I need to to use d-i preseed/late_command string apt-remove packagename to clean up stuff I don't want when the install is done, but I am not sure

• Steps to diagnose SNU5600 disconnection problem

  - by Rich

  I have a Philips SNU5600 WiFi dongle plugged into two machines (ie I have two SNU5600 dongles, one in each machine). One machine is running 10.10 and the other is running Linux Mint. The dongles work absolutely fine, except if I do a lot of file transfers to a NAS attached to the wireless router. After a while the connection to the router will go. To get the connection back I either need to run sudo /etc/init.d/networking restart or I need to unplug and plug in again the dongle. Otherwise the dongle works fine (web browsing, streaming, etc). Output of lsusb: Bus 002 Device 003: ID 0471:1236 Philips (or NXP) SNU5600 802.11bg Output of lsusb -v at http://pastebin.com/dXYKkF01 What steps should I take next to resolve this? Is it a known problem? Could it be the router? It is a 3Com "OfficeConnect Wireless 11g Cable/DSL Gateway Version 1.02.15".

• Disabling shutdown command for all users, even root - consequences?

  - by Rich

  I would like to disable the shutdown command for all users, even root, on an Ubuntu Server installation. The reason I want to do this is to ensure that I don't get into the habit of shutting down the machine in this way, as I SSH into a lot of production machines at the same time as this one, and I don't want to accidentally shutdown one of the other machines by typing the command into the wrong window. The server I want do disable shutdown on only runs inside VirtualBox on my Windows desktop, and I only use it for local testing so it is not a problem if I can't shut it down from the command line. I have already mitigated the problem a bit by ensuring I have a different password on the VirtualBox image, but obviously if I am within the sudo 'window' on one of the production machines, I could still accidentally shut it down. My questions are: How do I disable the shutdown command? If I do disable the shutdown command, are there any consequences that I should be made aware of? Most specifically, will it disable support for ACPI shutdown that is the equivalent of pressing the power button on a physical machine? Could it affect other generic applications? For information, I just use this VirtualBox image for trying out shell scripts, running Tomcat and Java, and that kind of thing.

• Display brightness adjustment not working

  - by nibot

  I have Ubuntu 11.04 installed on a Lenovo Thinkpad T410 laptop with nVidia GT218 display controller. I am unable to adjust the display brightness. Pressing Fn-Home and Fn-End brings up the display brightness on-screen display and the indicated level increases or decreases as it should. But the actual display brightness does not change. Earlier I was able to Ctrl-Alt-F1 over to a text terminal and then do Fn-Home / Fn-End to successfully change the display brightness, and then Ctrl-Alt-F8 back to the Gnome session with the new brightness. But after upgrading to 11.04 the psuedoterminals have disappeared.

• Starting java processes with Upstart

  - by user265330

  I want to start a java process using Upstart. Currently, on our OpenSuSE servers, I use the System V init system to achieve this, but on our Ubuntu servers I'd rather use Upstart. But I have two questions... I have an Upstart job (a task) that configures the server, called, say, myconfig. And in the job that starts my java processes I ostensibly have: start on stopped myconfig exec /path/to/myjavastartscript.sh myjavastartscript.sh runs 'java -classpath blah MyClass'. In System V init, starting the service runs 'nohup /path/to/myjavastartscript.sh &'. So my first question is whether I still need to do the nohup or run-in-background with the exec command? When running, MyClass starts other Java processes. In System V init, the service stop just looks for java processes owned by a certain user and kills them. My second question is how could I control the termination of these processes with Upstart?

• Ubuntu 13.10 New keyboard stuff bugged wine games

  - by karapinha

  I have made recently a fresh install of ubuntu 13.10. Since the first day I have problems with keyboard probably because of the new ibus thing... My language is PT-PT. One of those problems is the wrong behaviours on wine. games I was running in ubuntu 13.04 (tomb-raider, Skyrim, Shadow Warrior and Dark Souls) installed in the new ubuntu 13.10 they started to get key stuck when there is a combination like W+D+R (Drifting right + reloading) and its not because of windows/wine problems because the prefixes are the same that I had in 13.04. The key stuck as already been reported on winehq for Skyrim for some one using Linux Mint that was based on the 13.10. Is there a way of making the keyboard work like I was in 13.04? Or can i change the input type? Or downgrade ibus or something like that?

• How will Qt 5.0 be packaged for Raring?

  - by George Edison

  Note: as per the FAQ, "Issues with the next version of Ubuntu" may not be asked as questions here but in my opinion, this is not an issue but merely a question asking about policy. If you feel this question is off-topic, please leave a comment explaining why or open a question on Meta.AU. How will Qt 5.0 be packaged for Ubuntu when it is released? Currently, the name of the package for installing the Qt 4.8 core libraries is: libqt4-core Will the equivalent package for the next version of Qt (5.0) be named libqt5-core? If not, what will the package be named? Will the existing Qt 4.8 libraries coexist with the Qt 5.0 equivalents for the foreseeable future or will they be removed? The Qt 5.0 beta 2 PPA contains a lot of packages - few of which seem to correspond with existing package names. If someone can provide me with a link to a policy outlining the Qt 5.0 migration plan, that would be awesome.

• Cannot mount one usb disc, although other mounts automatically after 12.10 upgrade

  Since upgrading to 12.10, switching on or attempting to mount one of my usb hard drives gives this error message: Error mounting system-managed device /dev/sdg1: Command-line `mount "/mnt/usb-ST350041_8AS_60CAFFFFFFFF-0:0-part1"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdg1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg | tail gives (inter alia): [ 1080.727830] sdg: sdg1 [ 1080.732003] sd 8:0:0:0: [sdg] Attached SCSI disk [ 1081.383633] FAT-fs (sdg1): Unrecognized mount option "x-gvfs-show" or missing value [ 1871.160973] sdg: sdg1 The drive cannot be mounted, but is recognized by the system as a "place".

• Nvidia dual monitor configuration gets lost every time I reboot

  - by sunwukung

  I've recently updated (well, borked then completely reinstalled) to 12.04. I'm running a dual monitor setup, with a Dell U2410 / Dell 2007WFP combination on an HP Elite Book 8560W. The graphics card is an NVIDIA GF108 [Quadro 1000M]. My problem is as follows. I can get the dual monitor setup working fine, but every time I reboot, my machine appears to lose the settings (specifically, the U2410 is disabled, the mouse pointer is locked in the launcher). I have to restate the settings after every launch. I've tried running nvidia-settings as sudo, I've save the changes to my xorg.conf file (see below) but nothing seems to be sticking. Has anyone had similair issues, or know of a fix?

• Ubuntu 12.04 LTS can't add Cheese widget

  - by Burke Hodgson

  Command-line 12.04 Cheese (cheese:4144): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel Is there a fix so that Cheese will work in Ubuntu 12.04? The program comes up but the webcam area is black. I am running Unity 2D on a T42 Thinkpad. All programs similar to Cheese recognize my webcam as does Skype, but I really like Cheese and the error message may be ominous for other software failures.

• How to filter content in the cureently opened folder?

  - by peter matis

  there is one thing I'm missing since I've been forced to move from osx to ubuntu. for osx there is wonderful file browser named Path Finder which has very handy filter function build in. the search field in the Path Finders upper right corner isn't searching your whole HD, it's not searching in all the sub folders of a given directory (like in nautilus). it's just filtering the content of the folder you have currently opened whithout loking in to the sub folders. is there something similar (plugin, exstention...) available for nautilus? two users are already asking the same question, but the answers obviously missed the point.

• Digital Audio Output light on on MacBook Pro

  - by Emerson Hsieh

  I don't know if this problem happened when I installed Ubuntu before. Recently I noticed that when I boot Ubuntu, the Digital Audio Output light automatically switches on. Digital Audio Output light on means "Something wrong in the headphone port". Although my headphone is working in Ubuntu. I've heard that the headphone contains some magical "switch" that will fix the light problem. So I poked the headphone port with chopsticks, pens, paper clips, even my finger, and the Digital Audio Output light still stays on. I don't have this problem in OSX. How do I switch the light off?

• What's the story with TRIM support?

  - by Kent Boogaart

  The situation with TRIM in Ubuntu has me utterly confused. I don't know whether I need to manually run it or not. Sources I've found are disparate and unclear. I have Ubuntu 10.04 with latest updates (including kernel 2.6.32-26). I have an Intel X-25M drive with latest firmware, and it is formatted as ext4. So, does TRIM support run automatically? If not, how do I check if I need to run it, and then how do I run it if necessary?

• Why does my WIFI connection drop every 5-20 minutes?

  - by Benett Freeman

  There are other questions on this but none have been taken very far in their analysis. I get disconnects very often - sometimes every 20 mins or so, but sometimes even every few minutes. The way I have been getting around it is to disconnect from the Wifi connection and reconnect - and then it works fine again until the next disconnect. I am running 11.04 on an ASUS A52F. Can anyone help me please?
