• Rendering transparent textures in directX

  - by Vibhore Tanwer

  I am working with a directX application with WPF, I am facing a problem with videos and images that contains transparent pixels, I have to draw a color in background an then a video/image over it. What I expect is background color should be visible while playing video only non transparent pixels should be visible but what I get is a black background behind the video. I am using following settings on device to achieve alpha blending : device.RenderState.SourceBlend = Blend.SourceAlpha; device.RenderState.DestinationBlend = Blend.InvSourceAlpha; device.RenderState.AlphaBlendEnable = true; What am I missing here? What is the best approach to handle transparent videos? Any help will be of great value to me.

• How to make my microphone unmuted on startup?

  - by fiktor

  Every time I boot the microphone is muted. I want it to be unmuted instead. Of course I can do it by 6 easy steps every time: press sound icon in the upper right of the screen. press "Sound settings..." item in the bottom. wait about 10 seconds until a window loads. switch to input tab. uncheck "Mute" checkbox near a microphone icon. close the window. But I want it to be unmuted by default. I guess that in linux world this should be changing 0 to 1 in some line in some configuration file, but I don't really know, where is this line located.

• No sound in 12.04 on VirtualBox

  - by john crisp

  No sound when installed in VirtualBox. When I boot from the live CD in Windows, sound works fine on my speakers. When in boot the live CD in VirtualBox it does not see my speakers. In sound properties only digital output built in S/PDIF and headphones! I've done the pavcontrol - alsamixer - all settings are OK. I've tried both 32/64 versions of Ubuntu. Running current version VirtualBox. System: Windows 7 64 - i5. What am I overlooking?

• Closing lid does not suspend laptop

  - by fgysin

  I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

• Can't ping external websites

  - by Frantumn

  I can't ping google.com with my virtual ubuntu 12.04 server. I have set up a proxy URL in my /etc/apt/apt.conf file and it says Aquire::http::proxy http://urlname.com:9999; Now, I don't know a lot about how the proxy works, but I do know when we use it on windows VMachines it's a pac script that we place in internet explorer LAN settings and it automatically detects the script and gives internet access. I tried including the 9999/proxy.pac in the apt.conf URL and it didn't seem to work any better. Would ubuntu know how to handle a proxy.pac assuming it was created for windows? Should my URL include the .pac or just end after the port numbers? I've tried both without sucess, but I would like to know. A quick test to ping a fellow co-workers' PC was sucessful. So I can see network computers, but not google. or other internet sources.

• how to add programs to ubuntu without internet access

  - by captainandcoke

  I don't have internet access at my home and it takes me about a half hour to ride my bike to the library. I have downloaded .deb files to try to install at my home computer but everyone I have downloaded says it can't install because it depends on package X. The next day I will download package X and it will require package Y. Is there anyway to find out what ALL the sub-dependencies are for deb files? I have tried to boot from USB or External Hard drive on the library computers but the security settings prevent this. Also, I do not know anyone with a Linux computer.

• The perfect RDP experience from Mac to Windows

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information For the reasons I mentioned in my keyboard remapping blog post, I live in a Mac+PC world. This means, I find myself frequently RDP’ing to Windows Machines from my Mac. And yes, that Metro UI on RDP is even more frustrating than it is without RDP. Mac is a different OS than Windows (duh!), and the way it handles multiple screens and spaces is entirely different from windows. This means, RDP experiences are tough to make 100% seamless. You can see the frustrations in the various reviews on the Microsoft RDP app on the Mac app store. It can be difficult to find the perfect settings for the perfect user experience. Well, here they are - Read full article ....

• How can I restore a country specific apt-get update mirror?

  - by ferrarimarco

  While configuring my new 13.10 installation, I chose to change the default update server using the "Software & Updates" GUI tool available in the System settings panel. Before this change the selected update server was "Server for Italy" (I live there). Now it's one of the mirrors available in the list of mirrors (one of italian ones). How is "Server for COUNTRY" chosen in the list of mirrors for a country? How can I restore the "Server for Italy" option? Is it advisable to do so? I want to revert that setting because I found that the selected mirror is not up to date (checked from Here).

• Is it save to configure "Shutdown" on "When laptop lid is closed" ?

  - by Takkat

  To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

• KDE fonts not rendering bold in Ubuntu 12.04

  - by Doran

  I'm using Ubuntu 12.04 with some KDE programs: kate and yakuake. Neither of these programs will render bold font. Instead, the font appears as "Regular". How can I fix this? The image below shows an example of Kate rendering python with the stock python highlighting (the colors are inverted using CompizConfig Settings Manager's Negative option). The following words should have appeared bold: class def __init__ lambda + print Similarly Yakuake (or perhaps, the underlying Konsole) is not rendering bold. My LS_COLORS includes: di=01;34 (bold blue) Below is my gnome-terminal rendering bold fonts just fine.

• How can I change my "Desktop bar"?

  - by d_Joke

  The problem: In Gnome 3.4 when I click the main menu, it's white. The text of the menu is also white. Original text: I have a problem. When I installed the new version of Gnome (3.4) the "Desktop bar" (I'm sorry, I don't know what's the real name of that bar, but is the bar on the top on Ubuntu 11.10) every time I click on the username icon, or the battery, etc., the menu comes on gray or white and the letters are white. I know maybe this is a stupid question but it annoys me. Besides, my username doest not appear on the login screen. I tried to reset my settings, I delete gnome, and check the Unsettings and CompizConfig but the problem is still there. Maybe I miss something on the process of looking on any configuration tool but I don't think so... Sorry if the question is something basic or even stupid but I'm new on Ubuntu and I'm experimenting whit it.

• How do I completly remove software? [closed]

  - by Dustin

  Possible Duplicate: Why are the hidden settings-folders not deleted when purging an application? Ok I have 8GB on my desktop dual booting win 7. I installed a few games, assualtcube, tremolous, and spring. But I had removed them using 'remove --purge' and only to find they are still lingering and purge does not well truly purge them. I need them completely gone and not secretly hogging space when I purged them. How can i completely remove software, like it is gone and not going to take any more of my precious space? Shrinking 7 and growing Ubuntu is not an answer I am accepting, i want to know how to completely remove software. Thank you for your time and your answers.

• Screen Scaling Problem

  - by Glenbot3000

  I think this is what it's called but I'm not quite sure tbf, aha. Yeah, so I updated packages last night like I do every night, and when I booted my computer this morning I had a problem whereby the display ran over the edge of the screen. This has been a problem for a while, but I rectified it by changing a setting on the nVidia program, however I think it has been updated to remove said feature as I can't find it anymore. I have no settings on my screen to adjust this either, so I'm sorta stuck without the ~20px around the contour of my screen. It is a problem at all available resolutions. Here's a lil' pic of my problem: https://docs.google.com/file/d/0ByPHeBI8W35GcmZYOThWZ0hGd0k/edit Edit: Probably also worth mentioning the screen was originally detected as "Laptop" in the Display setting and had many resolutions to choose from, however now it's displayed as "OEM" and only has three.

• After 12.10, no GUI can authenticate for administration, such as Software Center

• How to get differents backgrounds for each desktop working properly?

  - by MaikoID

  I've followed all the instructions for getting differents wallpapers for each desktop. I'm using Ubuntu 10.10. I've installed compiz-fusion-plugins-extra to add Wallpaper plugin on my Compiz Settings Manager (ccsm). But unfortunaly I cannot get my wallpapers working properly. I follow these instructions http://ubuntuguide.net/different-wallpapers-on-each-workspace-in-ubuntu and I just get a black background. Everything works fine after I press Win+P (I don't know what is this shortcut, refresh output I guess) or switch between ttf1 and ttf8 (ctrl+alt+f1 and ctrl+alt+f8). I tried reboot but the problem persist. What can I do to resolve this issue ?

• vlc issue with unity

  - by bob

  I'm using ubuntu 12.04 with unity 3d. I am having troubles to lock vlc (version: VLC media player 2.0.1 Twoflower (revision 2.0.1-0-gf432547)) to the left panel. It doesn't behave the same way other applications do. This is a fresh install from the repo, I didn't change any settings. Ubuntu 12.04 is also a fresh install. For example, (left) clicking on it doesn't bring it to front, but creates a new instance (this in particular is very annoying, if it gets behind another window, that happens to be maximized, there is no way to bring it back up). It also doesn't have a right arrow to say the number of instances there is. Any way around that ?

• Google Analytics goal funnel does not recognize virtual page views

  - by Webber Smith

  I have a setup wizard with 3 steps. Since I'm using AJAX each step uses a virtual pageview with an appropriate URL for each step (see below). The pageviews are being recorded in the Content section of Google Analytics but the Goal Funnel still shows zero for each step. I've tried advise on other forums such as... Make sure Goal URL is set to Exact match Make sure no steps or the Goal URL are a parent directory of any other steps. For example, don't track /wizard/ as a Goal/step and track /wizard/step2/. Not sure why this would be a problem since it is an exact match, but it shouldn't hurt so I tried it... Require (or don't require - tried both) the first step in the funnel ...but none of these seem to work. Thoughts? Goal Settings Exact match : "/wizard/setup-complete/" Funnel Step 1 : "/wizard/step1/" Step 2 : "/wizard/step2/" Step 3 : "/wizard/step3/"

• installing win7 x64 in VirtualBox - error driver device missing

  - by chrisjlee

  After creating a vhd and going through that process i'm unable to install win7 x64. I've went through various settings and trying to get it right. It'll boot the windows install but then indicate the following error (image included too): A required cd/dvd drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now. Note if the windows installation media is in the CD/DVD drive, you can safely remove it for this step. I've also set up my storage tree like so: Would anyone know what the issue could be? It's asking for cd/dvd device drivers and i'm unable to install.

• Windows 7 doesnt boot after installing Ubuntu 12.10 (Asus Zenbook Prime / UEFI problem)

  - by jpdus

  Today I installed Ubuntu and since then i cannot boot into Windows anymore. I used the "standard" option (didnt change any partitions manually, just entered the size) but used the UEFI-mode. At first the GRUB entries for Windows did not work at all, after reading this thead i was able to add a new Grub entry - now i can get into the "windows-loading" screen for a few seconds but then i always see some kind of bluescreen for a fraction of a second and the laptop reboots. I can get into the windows recovery partition but the only option there is to reset everything to factory settings (+erase all data). I have no idea how to get into the Windows 7 repair mode which was mentioned here (tried everything else in this thread too - no success). My boot info can be found here: http://paste.ubuntu.com/1411573/ I have no idea what went wrong (there is even an extra page for the Zenbook Prime where no installation problems are mentioned). I would appreciate any help/ideas, many thanks!
