• Scale / Spread shows windows from all workspaces in 12.10

  - by dusktreader

  I used Ubuntu Tweak to set up the lower left corner of my screen to activate scale/spread/show_windows/whatever_it's_called. When I upgraded to 12.10, it now shows all open windows from all work-spaces. It used to show only windows from the current workspace. However, when I use super-W to do the same thing, it only shows windows from the current workspace. What is going on here? This feature is one of the main reasons that I use Unity (along with Dash and HUD), and without it working properly my productivity is hurt a lot. Does anyone have a direction that I could look in to fix this?

• Unable to use separate X-Screen's GTX 550ti Ubuntu 12.10

  - by user12622

  I am currently trying to get from "Twin View" to using separate X screen's on Ubuntu 12.10, however I'm not having a great deal of luck. I am using an Nvidia GeForce GTX 550 Ti and am on driver version 304.51 Initially, when I turn on the separate X screens option, presents me on the 1 monitor with a box to accept the changes, however the 2nd screen goes black, and effectively, Ubuntu only seems to recognise the one screen. When I reboot, I boots back into Ubuntu with both screens working in Twinview. I'm not too sure where to start, but my xrandr can be found: Xrandr Any help is greatly appreciated, this is the last but one thing I need to make Ubuntu my only OS, so fingers crossed we can crack it :)

• CreateDXGIFactory Doesn't Let Program Exit

  - by smoth190

  I'm using CreateDXGIFactory to get the graphics adapters and display modes. When I call it, it works fine and I get all the data. However, when I exit my program, the main Win32 thread exits, but something stays open because it keeps debugging. Does CreateDXGIFactory create an extra thread and I'm not closing it? I don't understand. The only thing I would suspect is that in the documentation it says it doesn't work if it's called from DllMain. It is in a DLL, but it's not called from DllMain. And it doesn't fail, either. I'm using DirectX 11.

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

• My wireless connection isn't working well

  - by Maikel Braas

  So this is my problem, I intalled ubuntu 12.04 with the wubi.exe and everything works fine, but my internet connection. When I try to install a program or use firefox, it goes with 24kb/s with a little luck for 1-2 seconds and then my internet terminates and it starts up again after 3-5 mins. Then it goes with an other 24kb/s and this will repeat. The thing is my connection works perfectly with windows. The laptop its running on is a Acer ASPIRE V3-771G. I tryed using a different network adaptor but that didn't help either. Please, some one help me with this. friendly regards, Maikel

• Building a website, wondering how to add news to it? Details inside. [closed]

  - by Robolisk

  On the home page of my website, I'd like to add a "news" kind section, where I can add blogs and such. Now from my understanding if this was all done in hard coding I'd have to go into the code just to add stuff to it. I've looked at things like drupal and I get how those work, but I how would I be able to add this to my site? The same kind of concept? Also, one more thing, what does inc operating php into a website offer? like better looks or general preformence? I don't understand this. Excuse my grammar/spelling. (: And thank you for taking the time to read this.

• How can I get stats for what 3rd-party sites have embedded our iframe widget?

  - by Su'

  Say we've produced a widget for other sites to use, like so: <iframe src="http://example.com/whatever.php" frameBorder="0" width="200px" height="300px" scrolling="no"></iframe> The client would like to be able to see within GA who has embedded the thing. Is there some referer information automatically passed that I can look for, or do I need to add something? whatever.php is already loading the analytics Javascript(we're also tracking clicks on an outbound link). [EDIT] Looking around a bit more, I found what seems to be a similar question on SO with an answer saying this can be found, automatically, but I still can't seem to find the information. The question's also old enough the respondent is probably referring to the old interface, though. Maybe someone could explain getting to it in the new look. (I won't likely be able to train this client to switch, deal with the old look, etc.)

• DRIconf in Ubuntu 64x plus ATI GPU or something more?

  - by Balask

  I've been trying to get Call of Duty 2 to work in Wine in Ubuntu. It gives me a black screen. So I tried the fix suggested by the wine apphq and downloaded DRIconf. Funny thing is that it can't find my direct rendering device. "Could not detect any configurable direct-rendering capable devices. DRIconf will be started in expert mode" When I enter into it in Expert Mode is just errors out anyway. fglrxinfo gives me: display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11627 Compatibility Profile Context That shows me my driver is installed correctl,y right? World of Goo which is Linux native and requires direct rendering works like a charm. So I'm wondering, is there some other workaround? Is there a bigger issue? Does me running 64-bit affect it at all?

• Multiple ( V- / I- ) Buffers, is it sane?

  - by Techie

  Currently I am developing an RTS game using XNA ( / ANX.Framework ). There is one thing bothers me. I am not sure in what way or how to organise Buffers. Should I use a new Vertexbuffer for any object ( e.g. a Char, a Table, an model ) or is it better to use ONE HUGE/ BIG Buffer to store any geometry in? I am still new to 3D Programming though I finished yet couple games using DirectX 9. Well, I hope this question qin't a duplicate and I appreciate any answer leading me into the right direction.

• How can I get media keys working on my keyboard?

  - by Victor9098

  Just got a new keyboard, the Microsoft comfort curve 2000, and everything seems to work fine accept for the 'back' and 'forward' multimedia keys. I am running Ubuntu 11.10 and have tried going into system settings - keyboard - shortcuts, then I try and hold down the keys to set the action I want them to perform, but nothing changes. Any thoughts on where else to look? Thanks -- UPDATE -- I rebooted and the options to change the keyboard shortcuts seem to be working now. Now I can tweak the whole thing and I managed to assign the media keys correctly. Thanks to everybody for the suggetions

• Windows 7 and Ubuntu Boot issue

  - by user115137

  I had the idea to dual boot Win 7 and Ubuntu and what I did was the following: Made a clean install of win 7 using all of my hard drive, next I used the Ubuntu live cd and gparted to partition my drive to be the following: /dev/sda1 ext4 20GB (Linux root) /dev/sda2 ntfs 100GB(Win7) /dev/sda3 ext4 350GB(Home) /dev/sda4 extended 4GB(swap) The thing is, when installing ubuntu I deleted the partition win 7 creates for its boot sector and recovery and then resized the drive to look like what I mentioned, and Ubuntu installed GRUB to the MBR. When GRUB boots I can see Ubuntu but not Windows, how can I chainload it? Or should I fix the windows mbr with the windows 7 installation disk and try to set the dual boot from there? I don't really care which one of the 2 bootloaders I end up using, I just want the dual boot to work out. Thanks

• Blank Screen ... No Bios Loading Screen Either

  - by SwissStar

  I don't even know how long it's been but I had given up. until now. My screen does not come on AT ALL, not even and the Bios loading screen. I have to connect it to my TV in order to see. But there's one thing that has always started it back up, and that is by running a hard ware Diagnostics * Provided by DELL* . It is definitely has something to do with Ubuntu. I know that for sure, because I remember running an update and BAM . That was it for the screen. How could I restore my screen back to Life ? I have a Nvidia Graphics Card.

• How can redirect pages from old core PHP site to new Joomla site?

  - by pkachhia

  We have our old site into core PHP and we have developed it again into Joomla 1.5 last year( because of some limitations we have to build it into 1.5). Now the problem is the URL of sites changed as we have use SEO URLS on joomla. In between we have use .htaccess to redirect user from old URL to new like this Redirect /pages/oldpage.php http://www.mydomain.com/products/category/new_page.html Is this good practice to redirect user to new URL or not?(we have used same server). One more thing, We have used splash page on our site, and to set up it we have made some changes and because of it one of the important link is not working, and it is http://www.mydomail.com/index.php How can I get rid of it? I have used DirectoryIndex splash.html home.html index.php in .htaccess to open splash page first when someone open my site http://www.mydomain.com. Note: my website hosted on dedicated ubuntu server.

• Ubuntu doesn't boot after upgrade

  - by Hugtrw

  I updated to 12.10 and the OS will not load. I used the boot repair cd, and the only thing that works is the monodeset option in the kernel and the graphics are terrible, mouse disappears and unity will not load. Ubuntu 12.04 ran great. On a clean install of 12.10 Ubuntu wont even load to install unless under using monodeset. I get left a terminal like screen with just a blinking bar. I'm using a HP Compaq NC6400 Laptop, Ubuntu 32-bit, 2gb ram.

• JavaFX in a JSF 2.0 Custom Tag?

  - by Geertjan

  I followed these instructions and now have a simple JSF 2.0 tag handler: The reason I created this is because I'm curious about whether it would be possible to change the tag created above: <my:hello name="Jack" /> ...to something like this: <my:chart type="pie" xAxis="${some-expression}" yAxis="${some-expression}" width="300" height="500" /> Has anyone tried this? That could be a way to incorporate a JavaFX chart into a Java EE application. That's different to how Adam Bien is doing it in LightFish, but might be a simpler and more reusable way of doing the same thing.

• HTML Tidy for NetBeans IDE 7.4

  - by Geertjan

  The NetBeans HTML5 editor is pretty amazing, working on an extensive screencast on that right now, to be published soon. One thing missing is HTML Tidy integration, until now: As you can see, in this particular file, HTML Tidy finds 6 times more problems (OK, some of them maybe false negatives) than the standard NetBeans HTML hint infrastructure does. You can also run the scanner across the whole project or all projects. Only HTML files will be scanned by HTML Tidy (via JTidy) and you can click on items in the window above to jump to the line. Future enhancements will include error annotations and hint integration, some of which has already been addressed in this blog over the years. Download it from here: http://plugins.netbeans.org/plugin/51066/?show=true Sources are here. Contributions more than welcome: https://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.4/misc/HTMLTidy

• Generic Content Player?

  - by Jantire

  The general idea on the web appears to be that video/audio are to be separated with plain text. By separated, I mean you have a place that plays video/audio and a place that you read text. This is because it is widely understood that they are vastly different. However, audio and video are just another way of communication, just like text. So why do we separate the two even if they are nearly the same thing? Correct me if I'm wrong but, most tutorials are either plain text how-to's (wiki-style) or visual/auditory instructional videos (YouTube). Why aren't the two combined? Or, if it's already been done can someone reply with the link? This might be bordering off-topic and if it is off-topic then please point me to the right place so it won't be. This might also appear to be an obvious question, however I'm not sure if this subject has really been deeply thought-out by more than a few individuals.

• Downloading anything is hell and arduous without an application. Care to help out an Ubunt-noob?

  - by FilthyCasual

  Torrent from the Pirate Bay even though I have Tixati installed and working? Asks for an application which I don't have (apturl or something similar?) Trying to get the latest AMD Radeon drivers automatically installed? the main file downloads...but just shows up in a window full of files but idk where to drag them. And PlayOnLinux my one hope for gaming since Steam is buggin out without proper drivers? Can't figure out where to "mount" the DVD version it asks for. I'm so lost. I dove head first into the Linux thing thinking it was wildly superior, and maybe it is, but dang if the simplest things aren't hard to do. Any help appreciated. I've been reading guides and manuals but what I need is human experience most of all.

• How do I get HDMI out working on an Acer AC700 HDMI?

  - by Kyle

  I have installed Ubuntu on my Acer AC700 (Chromebook) using both the Cr-48 method and the script method both of which I think are the same. The only thing that does not work is HDMI out. I assume this is because it uses the Chrome OS kernel to boot so I have hoped that eventually it would update and work. I'm currently running 12.04 with Kernel 3.4.0 and still no luck. I've tried booting in recovery for Ubuntu and attempting to get Xorg to generate a new config but I don't know enough to do anything else and that didn't work. Am I the only one out there? Is there no one else who wants this to be possible Any help is greatly appreciated.

• Strange issue with Wordpress sites, is it PHP Memory?

  - by Drai

  This has happened to me twice with the same host and I want to know the real cause. I have multiple wordpress sites hosted on a shared server. One day when I attempt to visit any of the sites, the webpage simply downloads the index.php file. It happens on all wordpress sites but not on static sites hosted there. I understand this is a php issue on the server, but what could be happening specifically? the only thing I could find when searching is something to do with memory limits. Is this common? Should I be worried about this host?

• Is there an (open-source) ReST-based blogging/forum package out there?

  - by Malvolio

  The site I work on is almost entirely in Javascript, it just goes back (via Ajax) to the server for authentication, database access, things like that. My boss would like me to add blogging, forum, and commenting capabilities. I don't want to implement it from scratch and I certainly don't want to integrate some HTML-generating PHP atrocity. Ideal, I'm looking for a package that does all the backend work and offers ReST interface so I can write a Javascript-based UI that integrates nicely with the existing site. Does such a thing exist?

• Looking for best approach to create new projects for enviroment specifics files

  - by Ness

  ClearCase Question... Overview of requirements: There are 3 diff environments (DEV, TEST and PROD) which have a folder called 'common' that users across all envs. There are multiple servers in those 3 envs and we want to store their server environment specific configuration files in Clearcase. The executables files are different for each environment. Thus there will not be cross delivery require between dev/test/prod. Any thoughts on how we can approach this? Is keeping it simplest is the best approach here? One component to one vobs as (DEV_Serv1, TEST_Serv1, PROD_Serv1, Dev_Serv2, Test_Serv2 and etc)? OR Have multiple components VOB? One other thing is developers here like to use snapshots views.

• Gridview - Conditional Images

  This Gridview sample shows how to, for each row, based on other data within that row, to show a different image. We do this by creating a TemplateField, and putting an ASP.Net Image control within it, called 'Image1'. Then, inside the RowDataBound event of the Gridview, we put code, which first, checks and finds the Image control in that row, and then assigning a different JPG file to the ImageURL property of that image. One other thing here, you'll notice, is that when the criteria is matched, we set the Image control's Visible property to 'True'. That's because, one extra criteria is, that if the Units In Stock is larger than 80, we set the Image control's Visible property to 'False'. Naturally, since we're checking one particular column in the Gridview for this data, we're using a Select Case statement.

  I have one domain, www.example.com, and www.example.com/sales. the analytic code on both urls are different. so when i login to google account, it will show two separate analytic accounts. on www.example.com/sales, i have a banner linked back to www.example.com. i clicked that banners, and i am sure there are other people have clicked the banner as well. but when i check the analytic of www.example.com, i don't see any thing come from my example.com/sales.

• Pointers to implementing a taxonomy system?

  - by petsagouris

  I am taking part in the development of a PHP CMS (yeah I know you are like, meeh). It is currently using simple tags for tagging content. What I want to do is push the whole thing to using Taxonomy but I am not sure on what to pay attention to, or how to go about structuring the whole vocabularies/terms. I'd love to be able to keep the user interaction close to that of the current simple tags and at the same time allow for more advanced usage by power users. The Drupal and the Wordpress taxonomy systems are being reviewed at the moment and they provide valuable resources. Nevertheless, it could be that someone has some simpler and more appropriate thoughts on this matter.
