• Which API for cross platform mobile audio?

  - by deft_code

  This question focuses on the API's available on phones. I'd been planning to use OpenAL in my game for maximum portability. It runs great on Linux so I can quickly develop the Game and leverage it's superior debugging tools. However I've recently heard that Android doesn't support OpenAL well. Instead they've gone with a OpenSL ES library. What I'm looking for is a free Audio library that I can use with minimal custom code on iPhone, Android, and my Linux desktop. Does such an API exists? Some extra details: The game is written in C++ with custom minimal front ends. ObjC for iPhone, Java for Android, and SFML for Desktops. I'm using OpenGL ES for portability as iPhone doesn't support the more advanced OpenGL APIs.

• URL parameter names being changed by user agents

  - by Mike Deck

  In reviewing one of our site's web logs I'm seeing instances where we are returning a 404 to requests because we're expecting an id parameter to be sent, but instead we're seeing a di parameter. The resource in question is an image but which image file actually gets served is dependent on the id parameter. The expected url is something like http://images.mysite.com/photo.gif?id=123&width=200&height=300 What I'm seeing in the logs is requests for http://images.mysite.com/photo.gif?di=123&width=200&height=300 The only case where we are seeing this on the id parameter. It seems unlikely that this is due to a server side or JavaScript bug since it seems to be only effecting a small percentage of our traffic. We are seeing this across a wide variety of user agents (both mobile and desktop) and IPs. Has anyone else seen this? Is there a browser plugin or other software you're aware of that could be causing this, and if so is there a good way to work around the issue?

• Clone Unity Dock for All Users?

  - by jduc

  I've spent 3 days trying to figure out how to clone the Unity dock from my firstuser profile in Ubuntu 12.04 to all of the other profiles I'm hoping to create. I've read where the /etc/skel folder contents get populated to all new profiles but this doesn't seem to include the dock or the desktop folders and icons. I've also copied the entire contents of my /home/firstuser folder to my /home/seconduser folder (including .* files) but the dock is still showing the stock icons and not the icons I've designated in my firstuser profile dock. Does anyone have any suggestions?

• Broadcasting webinars to and from Ubuntu

  - by Chris Wilson

  I've recently attended an online workshop using Citrix GoToWebinar, a service that allows someone to broadcast their desktop and audio out to all members connected to the presentation as well as receive audio and screencasts from those attendees , and the experience was unbelievable, and I was wondering if there was any such service/software available on Ubuntu. Points to consider include, but are not limited to: Web services or local applications. Free (as in beer) or paid. Free (as in speech) or proprietary. Ease of use Ease of setup Any other point that anyone can thing of

Now when i tried playing videos in vlc (any format) full screen mode doesnt show controls and usually doesnt gets me out to window mode. it sometimes crashes to login screen.

• How to add reflection definition to read json files on web game

  - by user3728735

  I have a game which I deployed for desktop and android, I can read json data and create my levels, but the problem is, when it comes to reading json files from web app, I get an error that logs, cannot read the json file, I researched a lot and I found out that I should add my json config class to configurations, I added this line to gameName.gwt.xml, which is in core folder <extend-configuration-property name="gdx.reflect.include" value="com.las.get.level.LevelConfig"/> but it did not work out too, I have no idea where should I place this line, or where should I change to make my web app work, so I can read json files

• Broadcom bcm4311 rev2 Full disabled on battery

  - by Antonio BG

  Ok this is my problem... My problem begins while ago when I installed ubuntu 10.10. (is the same with 11.04,11.10...) My wireless card is disabled if the power cord is unplugged, and the only way to fix this is rebooting my pc WITH the power cord plugged and if I use lspci command, it doesn't show me the wireless card. is like if I've removed the wireless board from my laptop port. I've searched a lot of solutions for bcmw4311 issues, but none of them fix my problem because when apply one of the fixes, if I unplug the cord, my wireless card it just gone away... I have dual boot on my pc(w7,ubuntu), I've tried with full installation just to see if this is the problem, but not, is the same. On windows all work correctly with and without power cord.. so this is not a hardware problem, is more like a kernel problem. anyway I can use wireless with power cord plugged, but c'mon this is a laptop not a desktop pc XD haha any help is welcome

• HELP: I Broke Ubuntu By Uninstalling Compiz

  - by tSquirrel

  I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it. sudo apt-get remove compiz sudo apt-get install compiz I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04 How can I fix it? I'm not even sure how to get to a terminal or anything. The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how. Please Help! Right now I'm working off my W7 dualboot.

• Cinnamon on Ubuntu 12.04 stoped working after menu edditing

  - by Presbitero

  I have recently installed cinnamon on ubuntu 12.04 with success. After installing MS Office with wine my menu got messy so I tried to edit it with alacarte. After having found out that alacarte is not the proper way to edit it, I right clicked on the menu icon to edit. After just a few editing steps it breaks and cinnamon stopped working (no menus, no desktop icons, no applets, no window decoration, nothing). Now, when I login with cinnamon I just get the background image. I can login with gnome though. I have tried to completely remove cinnamon and nemo and reinstall it but it didn't help. I have no idea of how to get any king of diagnostics so if you ask something please explain how to do it or post a link with explanations. Many thanks for the help, I hope I will not need to format the pc again to make it work.

• Gnome Shell installed not working in Ubuntu 12.04

  - by user68180

  I had Gnome Shell working perfectly on my desktop, and I tried to install it on my laptop by the exact same method, (tried apt-get, synaptic and software centre), but it won't work. It seems to install fine with no errors. If I select "Gnome" at login, I get the "Gnome Classic" interface rather than Gnome Shell. My laptop has sufficient specs to run Gnome Shell. Am I missing something? EDIT: I have just discovered that under System Details Graphics, it says "Unknown". So, Ubuntu hasn't recognised my graphics card, and I'm guessing this is why Gnome Shell can't work. I have a nVidia GeForce GT 525M. How can I get it working? (as you may have realised, I'm a linux noob)

• Is it Possible to Repair Boot Record on Windows Vista Partition on Dual Boot Ubuntu 12.04.02 LTS Install?

  - by PasBonRJB

  I recently successfully installed Ubuntu 12.04.02 Desktop as a "side-by-side" on an eMachines ET1641-02w PC; which before had Windows Vista; but was no longer bootable, because the boot sector somehow got trashed. After I installed Ubuntu I can go to Devices/OS and I can access all of my docs, pics, videos, music, etc. on the Windows Vista partition; but I still can't "boot" the Windows partition. I've seen several posts regarding recovering boot sectors using the Boot-repair app; but am wondering if this "boot-repair" is only for the Ubuntu partition. Can I use "boot-repair" to repair the Windows Vista boot sector?

• Is there any way to downgrade or revert an update to the kernel?

  - by David

  Today I installed the linux 3.9 Kernel update (because I heard it would fix sound through HDMI which I no longer have since installing 13.04). After restarted my computer and logging in my screen has only a desktop, and no dock or tool bar. I tried to reset unity and compiz using guides like this one but nothing happens, even after reboot. Is there any way to downgrade or reset the update? EDIT: Running uname -a in terminal brings up 3.8.0 as my current kernel for some reason.

• Oneiric is freezing. Need help diagnosing and filing a bug

  - by mlissner

  Six months ago, I bought a new Sandy Bridge CPU and built myself a nice desktop machine. Until now it hasn't worked...at all. I finally have gotten it working now that Oneiric is released, but it freezes every so often, making it little more than a semi-functional temptation. What happens when the system freezes is: the music I have playing enters into about 5s loops. SSH fails the monitor freezes the mouse freezes the keyboard fails The only way to fix it is to do a hard reset...and that sucks. I'd love to at least figure out the source of the freeze so I can file a bug. I've looked in dmesg, kern.log, and the X.org logs. Nothing interesting is any of them. Since SSH fails, I'm convinced it's not an X crash: https://wiki.ubuntu.com/X/Troubleshooting/Freeze Anything else I can do?

• Unable to boot 12.04 server: no LVM activated and impossible to mount /

  - by baronKarza

  I'm stuck in the Busy Box shell after upgrading from Ubuntu server 11.10 to Ubuntu server 12.04 64 bit. During the booting phase the system hangs while mounting root filesystem. My system is so configured: /dev/sda1 -- /boot /dev/mapper/vg-lv_root /dev/mapper/vg-lv_var /dev/mapper/vg-lv_tmp When the boot process fails and I'm forwarded to the busybox shell, if I type vgchange -ay I can mount my volumes and all it's OK. But it does not enable LVM automatically so that it is impossible to mount root, var, and tmp. I tried to start with a Knoppix, chroot, reinstall (aptitude) both kernel and lvm2 as suggested by this tread "Fixing unbootable installation on LVM root from Desktop LiveCD": nothing changed. I can't figure out what is the problem. Any suggestion is welcome. Thanks in advance.

• Gnome Shell opens as classic

  - by Joe Horgan

  I'm running 12.04 on a Gateway LT4004u netbook, and I installed Gnome3 using the apt-get commands in the terminal. When I rebooted and ran "Gnome Shell" it opened up classic mode. I thought that my cursor might have slipped the first time, but on multiple retries logging in under gnome shell would open the gnome classic desktop. I even uninstalled Gnome Shell and reinstalled it with software center, but I still have the same problem. I was wondering if this might be an issue with my graphics card? Any help would be much appreciated, thanks! -Joe

• Kindle for PC via Wine

  - by Mollikins

  I've been checking out all the free books on Amazon and I really want to get the Kindle PC program running on my computer so I can download, read, and manage my e-books. I realize that Calibre can be used to manage e-books and I do have that downloaded. However, Amazon won't let me download ebooks unless my PC is registered in their little Kindle program and I'd like to just keep things streamlined by playing by the rules for once. I've viewed so many tutorials and advice for setting it up. I have Wine, I have Kindle for PC, I set it to Win98, all of that. However, when I try to open KindlePC from the Wine menu or from the desktop icon, nothing happens. No error messages, nothing. I don't know what might be wrong. Please let me know if you have any experience with this and any suggestions!

• Connecting Ubuntu home server to internet via laptop

  - by Gray-Wolfe

  I recently got a spare desktop computer from a relative to play around with and since I've been using Ubuntu for a few years I decided to install Ubuntu Server 12.04 to play around with and learn more. However it doesn't have a wireless card, the wireless adapter had a shipping error and will be awhile, and plugging it into the router is not an option. So I figured I could give it access to the wifi from my laptop(which I switch between Windows and Ubuntu) so I could at least get some things started and set up while I'm waiting for the adapter. However the few guides I can find to do that require a GUI, something lacking on the server version. Could someone tell me how to set this up via the terminal? I would appreciate it.

• High temperature on my laptop with Radeon Mobility HD4670

  - by Lorthirk

  As almost everyone here, I guess, in these days I downloaded Quantal Quetzal to give it a try. However I noticed that my laptop runs fairly hot with cooling fans almost always on, even sitting in the desktop doing nothing. I downloaded XSensor to read temperature sensors, and I saw that while CPU stays on about 65°C, so quiet normal I guess, the GPU sits at 75°C. In comparison my actual Windows 7 installation, which dual boots witb Quantal, stays at 59°C CPU and 65°C. So I went reading and learned that AMD dropped support for my video card from fglrx package, and that fglrx-legacy won't support 1.13 Xorg, so I'm basically stuck with OSS drivers. So I was guessing if there's anything I can try, and if it's possible that the OSS drivers could be the cause of the high temperature?

• MacMini (running Ubuntu 14.04) loses wlan connection when uploading larger files (several 100 mb) via ownCloud

  - by ManekenT

  I installed Ubuntu 14.04 on an old MacMini with the intention of running it as a homeserver. Additionally I installed ownCloud and tried to sync some files both from a laptop running elementaryOS and a desktop running windows 7. Syncing smaller files workes like a charm (4000 files at <10mb each) but when it comes to bigger files (1 GB ubuntu iso e.g.) the upload failes after 20-100mb. I can't ping the server anymore and the server can't ping me. It still shows up in our router as connected though. Disconnecting and reconnecting the wlan connection fixes the issue until the next attempt at syncing. Edit: I also had to install the wlan driver with this manual: https://help.ubuntu.com/community/MacBookPro8-2#Wireless

• Why doesn't the installer see all of my hard drives?

  - by atodd

  I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed. I've also tried both the desktop and alternate amd64 installs with the same result.
