• Oculus Rift with Antichamber

  - by Scott Hainline

  Antichamber runs great on linux (steam version). But it is not playable with the Oculus Rift at this point. The issues are: 1) no headtracking 2) graphics are not being split and distorted by Oculus SDK My current plan is to use LD_PRELOAD to add the functionality, this seems to be the linux equivalent of DLL injection. Antichamber appears to be using SDL, I'm hoping this can be configured to use the headtracking data as a joystick and apply the graphics distortion, but I am not sure which functions I should be looking for. Is there a simpler way of getting these issues resolved? Is SDL the right choice here? Would appreciate any information on how the Unreal Engine 3 works under linux; and library injection too.

  - by Ryan

  I am an ubuntu amateur trying to set up an ubuntu 11.04 server on a tower. I want to install things like ssh client/ server and gksudo on it but I get errors when trying to do so.

• How do i Setup Different Users to Folders

  - by Erin

  I am trying to setup a Ubuntu Server for an office. Its going to be a file share server that 4-5 desktops connect to and access the files. Im planning on having different access for certain computers so computer 1 has full access but say computer 2 can only see a certain folder. My question is, is this possible and how would i go about setting it up? All workstations are using Windows XP - Vista.

• How can I make multiple displays work on my Asus UX32VD?

  - by oKtosiTe

  Original title: Why do I have two trash icons in the Unity Launcher? Whether I run Ubuntu as a live-USB or install it, I always have two trash bins on the Unity Launcher. Both work, and both open the same location. This seems a bit redundant; what could be done about it? Update: Turning auto-hide on made it obvious that I have multiple Launchers showing. With auto-hide off, they simply overlap, making it look like there's a double trash icon, but with auto-hide enabled, I can display one Launcher (and therefore one trash icon) at a time. Still, two are running simultaneously. Second update: This problem appears to be caused by the way Ubuntu handles multiple displays on my Asus UX32VD Ultrabook. Somehow, the laptop display cannot be used while my external display is connected. It is shown in the Displays list, but remains black no matter how I configure it. The external display runs at 1920x1200, the laptop monitor should run at 1920x1080. It therefore becomes obvious that the Launcher that's supposed to run on the laptop display, is actually displayed on the external monitor. Using nomodeset as a kernel parameter as indicated here makes the laptop display inaccessible altogether, detecting the external monitor as the laptop display and making resolutions other than 1920x1200 inaccessible. That is not an option.

• Only run CRON job if connected to specific wifi network

  - by Herbert

  I am a newbie to scripting on Linux (Lubuntu), but I would like to make a script that runs a cron job only if my laptop is connected to my home wifi. Is this possible? I guess, I could do something with iwconfig and pull the ESSID from there with grep? So far, I tried this and it seems to work: #!/bin/bash # CRON, connected to specific WIFI clear netid=HOFF216 if iwconfig | grep $netid then clear echo "True, we are connected to $netid" rsync ........... else clear echo "False, we are not connected to $netid" fi

• apt-get update stuck on "Waiting for Headers"

  - by crasic

  I'm setting up a Maverick server on a spare PC. The install completes fine and the system boots up into the shell. However, when I try to do a apt-get update , apt hangs on almost every entry with the message 99% [Waiting for headers] sometimes a message of 96 b/s appears on the far right. The actual percent that it claims also varies. Searching around online gave a potential solution by using the option Acquire::http::Pipeline-Depth="0" this somewhat alleviates the problem, i.e. it stalls on every other entry with the same message as above. If you wait it out (the whole update took about 4 hours), the update still fails as a good portion of the hits show a "unable to connect" or similar message, despite the fact that I can ping the server from the pc just fine. The problem is also unrelated to the mirror used since I've tried about a dozen mirrors with no success, I've even tried commenting out everything but the main entry in sources.list and it still refuses to update. The network connection is fine since I can ping and wget (apt won't let me install lynx until I run a successful update) just fine. I've also reinstalled the distro with no luck. The only thing weird about the setup is that the PC is connecting to the internet through my windows laptop with ICS configured properly, but as I've said before, the network connection is fine.

• Mount drive on remote machine

  - by NikolaiDante

  My current set up is: I have my main machine (Darkseid) upstairs which has a drive with all my films on it, which I don't keep mounted. Downstairs, next to the tv, I have a htpc (Archangel) which has xbmc installed on it, which points to a samba share on the main machine. Everything works fine when the drive is mounted, but is there a script I can write to send a command to the upstairs machine from the downstairs machine to mount the drive to save the walk upstairs? #lazy Both machines are Ubuntu 12.04

• Multiple X screens without Xinerama

  - by Kalle Elmér

  Is there some way to move Windows between separate X screens in Ubuntu 12.04? With 3 monitors on 2 GPUs, using Twinview is not an option. Xinerama allows me to drag windows between all monitors, but it also means that I lose all hardware acceleration. I don't expect to be able to drag windows between the screens and have them occupy two monitors simultaneously, but there must be some way to transfer a program while it is running. At the moment, I don't even know how to select which monitor it will use when launched. Any pointers?

• Ubuntu 14.04 key arrow up is being pressed by itself

  - by Margo Nikolopoulou

  Keyboard's up arrow key is keep pressing itself every few seconds. I tried to install Ubuntu 14.04 via boot cd, even before installation the arrow key was being pressed by itself. I tried to use Ubuntu first without installing it and then tried to install it from there, the issue seemed to be fixed. I was using the PC for months until out of the blue the issue came back. IT IS NOT A HARDWARE ISSUE! Thank you in advance.

• When will we get Sandy Bridge support?

  - by Gu3miles

  I'd like to build a machine running Ubuntu and using the new Sandy bridge (i5 2500 specifically) intel cpu's. I heard that 10.10 doesn't have the best support (or simply won't work) with the new cpus and 1155 mobos. I'm assuming that 11.04 will have support but do the alpha's have it already? Or will I have to wait? Also, I plan to use the onboard Intel graphics (H67 mobo), will there be support for this or will I still need to use a graphic's card?

• Lubuntu from USB

  - by WGCman

  I have An Acer Aspire 1362 Laptop with AMD Sompron 2800+ processor and only 256MB RAM, with Windows XP installed. I have downloaded Lubuntu-12.04-alternate-i386.iso and installed it to a 16GB USB stick. I do not want to install Lubuntu on my hard drive (yet!). I have got the USB stick to boot, and am working my way through the menu. At one stage, the installer wants to partition my hard drive, so I abort the installation. There doesn't seem to be an option on the menu to boot and run Lubuntu from the USB stick without putting stuff on the hard drive. How can I achieve this, please?

• How to create a bootable USB stick?

  - by Deborah Shadovitz

  I am looking at this: http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me). Questions: What format do I choose for the USB stick? (I wish the instructions stated this). What is Dash? (Will I know when I run the installer?) Can I do this from a Mac or Windows computer? Or only from Ubuntu?

• DLNA Server/Control Point like Windows Media Player

  - by csde_rats

  Yes, I know that most questions ending with "like Windows" are odd, but this one really bothers me ;) If you ever used some DLNA renderer (in my case DLNA-enabled loudspeakers) you probably know the handy "play to"-feature. From my knowledge of DLNA stuff I would guess, that Windows Media Player is both a DLNA server and control point here, so my question is: Is there any similar software for Linux accomplishing the same thing with minimal configuration effort? I normally use Banshee for my music library, but it doesn't seem that there is anything available for Banshee...

• Upgrade from 10.10 to 11.04

  - by hemanta pathak

  On doing an upgrade from 10.10. to 11.04 using Upgrade Manager everything works fine. But on installing a software that bundle its owns runtime environment( loader and system files) and installs the custom runtime ( basically loader) in the location where the native one resides, the above mentioned upgrade fails.(Upgrade starts and after sometime it encounters an error and aborts.) Basically , /usr/bin/dpkg throws up an error on being unable to locate a system shared library in the aforesaid third party runtime folder ( /usr/bin/dpkg should not search the third party runtime folder.Instead it should look at the system default folder) But if we remove the installed third party loader from the default system location /lib and place it in some other location , the upgrade problem goes away. This makes me believe /usr/bin/dpkg invokes(loads) the wrong loader and as such goes looking for the dependent libraries in the third party folder. Can someone take a look at this ? is there some bug with dpkg

• Extension GLX missing...on a desktop PC

  - by Bart van Heukelom

  I just installed Ubuntu 12.10 on a new PC with an Nvidia GTX 560 graphics card, but after installing the Nvidia proprietary drivers (either -current or -current-updates), Unity won't start. When trying to start it manually I get the message "extension GLX missing". I've searched around and found results like this question which point out it's a problem with Nvidia Optimus laptops. However, I don't have this problem on a laptop, but on a desktop PC. lshw output for the graphics card: *-display description: VGA compatible controller product: GF114 [GeForce GTX 560 SE] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:f4000000-f5ffffff memory:e0000000-e7ffffff memory:e8000000-ebffffff ioport:e000(size=128) memory:f6000000-f607ffff and CPU: *-cpu description: CPU product: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz vendor: Intel Corp. physical id: 40 bus info: cpu@0 version: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz slot: SOCKET 0 size: 1600MHz capacity: 3800MHz width: 64 bits clock: 100MHz capabilities: x86-64 fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase smep erms cpufreq configuration: cores=4 enabledcores=4 threads=4

• Ubuntu 13.10 upgraded from 13.04 issues

  - by Andrew Sadach

  The keyboard stopped working after a while, I started using 13.04 again VIA USB because I am waiting for the keyboard issues that 13.10 has to get an update. 13.04 had tons of issues I didn't care about because most of it worked. Now almost none of it works. There's even a huge amount of graphical errors. Others have had these issues I've noticed while looking at the similar questions area next to this text box, but my question is can I downgrade 13.10 to 13.04?

• Wifi is connected but internet not working?

  - by Philip

  I have a lenovo x230 running ubuntu 12.04lts. I've been using it just fine for a while, but all of a sudden the internet's stopped working. It's connected to the router just fine (I can see the antenna bars saying it's connected) but when I try to go to a webpage, it's just loading forever. I've tried the fix listed here (http://ubuntuforums.org/showthread.php?t=1985079) but it hasn't done anything (the instructions are a little confusing though). I'm booting windows 7 right now and the internet works just fine when I'm on windows, so I know it must be a problem with ubuntu. I haven't touched any network settings before this problem happened, and I've been using it just fine for months, so I don't know why I'm getting this problem all of a sudden. Oh and I haven't updated anything in a few weeks (you know when the update manager pops up every so often listing all the things there's an update for) so I know it's not some update that broke it.

• Electricsheep Not Working in Raring 13.04

  - by Nhoeh37

  I just downloaded Electricsheep four days before I updated my Ubuntu software and I fell in love with it. After I upgraded to 13.04, I'm kind of upset in saying that Electricsheep no longer works. I have no idea how to fix it and I feel helpless with Linux. As I said, it was working completely fine in 12.10, but now with the Raring Ringtail update: I use Xscreensaver to launch Electricsheep. When I open Xscreensaver, "Electricsheep" is one of the options to choose. When I "preview" ES or even launch the "xscreensaver-demo" in the terminal, it doesn't work anymore; I get an error message. The error message says: "detected another electric sheep process. rendering of sheep is disabled using read only access." Damnit, can someone please help me? I want my trippy screensaver back, it shouldn't be this hard! EDIT: I contacted the creator of Electricsheep (Scott Draves) via the link to his email address on his personal website and asked for his assistance. Hopefully the Askubuntu community will be able to fix this problem, I'm sure I am not the only one who is having this problem as I have searched and searched.

• flashplugin installer works for firefox but not chromium-browser

  - by user829755

  I'm on Ubuntu precise (12.04.5 LTS) and I do have flashplugin-installer installed. When I click on flash videos in chromium-browser I get "An error occurred, please try again later". In firefox they display fine. I opened chrome://plugins to see if the flash plugin is installed and indeed it's not listed. Also http://www.codegeek.net/flash-version.php displays: "You do not have Flash player installed", while with firefox it says: You have Flash player 11.2.202 installed. Following some instructions on some ubuntu page I copied the plugin using sudo cp /usr/lib/flashplugin-installer/libflashplayer.so /usr/lib/chromium-browser/plugins/ and I started chromium using chromium-browser --enable-plugins but this didn't help. chrome://chrome/ says: Version 36.0.1985.125 Ubuntu 12.04 (283153). what else can I try?

• How and when is old-releases.ubuntu.com updated?

  - by muru

  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. Priority of documentation: Statements by Mark Shuttleworth (on his blog or other public statements) Pages from the Official Ubuntu documentation Ubuntu mailing list discussions, Launchpad bug reports (or questions) or blueprints, etc. IRC discussion logs for official Ubuntu channels Random gossip on the street Community Wiki.

• update-apt-xapian-index hogs CPU, even when Update Manager is set to not check for updates

  - by Dave M G

  I have a slightly older laptop running Ubuntu 11.10. It runs fine, but frequently, when I start it up, the CPU monitor in my Gnome Panel shows 100% usage for for what can be up to five minutes or so. It seems that the offending process is update-apt-xapian-index, which, if I understand correctly, is the update manager checking for updates. I have gone into the update manager settings, and selected to never check for updates. I'll do that manually when I feel like I have the time to leave the laptop running for that. However, despite my selection, this still happens. Roughly 50% of the time or more, when I start my laptop, it runs update-apt-xapian-index. How can I get the update manager to respect my settings, or at least to get this process to stop eating my CPU cycles?
