• Ubuntu 12.04 + Wifi not working

  - by user171154

  i'm having problems connecting over wireless. At the moment, I'm using wicd. It seems to get stuck on "Verifying AP association...". Without wicd I can get the connection up and ping the Net - but if I take eth0 down (ifconfig eth0 down), my wireless goes away too (same result if I unplug the wire instead). wicd is the only way I can bring eth0 back (which is the main reason I'm using it) - ifconfig eth0 and/or ifup eth0 do not re-enable the connection (I just discovered it leaves out the gateway. Adding the gateway back in re-enables the connection including wifi; I didn't want to delete the info about wicd above in case it gives someone an idea.) Doing it manually, despite the errors (which it would be nice to also resolve) - allows me to ping the outside world: ifup wlan0 ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument ssh stop/waiting ssh start/running, process 17336 ping -I wlan0 -c 4 8.8.8.8 PING 8.8.8.8 (8.8.8.8) from 192.168.0.12 wlan0: 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_req=1 ttl=43 time=48.8 ms 64 bytes from 8.8.8.8: icmp_req=2 ttl=43 time=47.9 ms 64 bytes from 8.8.8.8: icmp_req=3 ttl=43 time=48.7 ms 64 bytes from 8.8.8.8: icmp_req=4 ttl=43 time=53.2 ms --- 8.8.8.8 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 47.975/49.711/53.235/2.063 ms #

• Software center and update manager not working

  - by lmnop

  When I run update manager I always get this message "The action would require the installation of packages from not authenticated sources." details "libv4l-0 libv4lconvert0" I also can not get the software center to install anything. I get an error message telling me to check my internet connection but I am connected to the internet, shortly after I get an error message just like the one I get from update manager. How do I fix this?

• Dell Mini 9 Integrated Microphone -- not working

  - by Josh Eismanaf

  Im running the latest Debian version, 6.0 on my Dell Mini 9.Webcam and sound work, but microphone is a no-go. I hope even though it is Debian, fellow Linux users can help. In Alsamixer (1.0.23), I have Capture, Digital, and Mic settings all the way up. There are no options for adjusting "Front" mic settings. (May have been for older alsamixer versions?) In Sound Recorder, playback has loud noise/feedback? Under Preferences in Volume Control under the Recording tab, both Capture and Digital are permanently checked, regardless if I uncheck them. I'm not sure how to interpret the above, but I am just trying to offer as much relevant background information as I can. I've been scouring forums for the answer, but to no avail. Most questions/answers are from 2008, and couldn't find a solution. I'm not very handy with the Linux machine, but love to learn / am learning. Also, I've attempted the solution here, and it didn't work. Thanks, in advance, for your help!

• yahoo media player not working

  - by luca590

  I have a yahoo media player embedded in my webpage. I am currently using Ruby on Rails to create/edit my web page. When i click the play button next to a track the YMP waits a while and then goes to the next track without playing the first one. I then get a warning on my second (last) track that its file could not be found. Does anyone has a better recommendation for an audio player or a way to fix this one?

• MiniMax not working properly(for checkers game)

  - by engineer

  I am creating a checkers game but My miniMax is not functioning properly,it is always switching between two positions for its move(index 20 and 17).Here is my code: public double MiniMax(int[] board, int depth, int turn, int red_best, int black_best) { int source; int dest; double MAX_SCORE=-INFINITY,newScore; int MAX_DEPTH=3; int[] newBoard=new int[32]; generateMoves(board,turn); System.arraycopy(board, 0, newBoard, 0, 32); if(depth==MAX_DEPTH) { return Evaluation(turn,board);} for(int z=0;z<possibleMoves.size();z+=2){ source=Integer.parseInt(possibleMoves.elementAt(z).toString()); System.out.println("SOURCE= "+source); dest=Integer.parseInt(possibleMoves.elementAt(z+1).toString());//(int[])possibleMoves.elementAt(z+1); System.out.println("DEST = "+dest); applyMove(newBoard,source,dest); newScore=MiniMax(newBoard,depth+1,opponent(turn),red_best, black_best); if(newScore>MAX_SCORE) {MAX_SCORE=newScore;maxSource=source; maxDest=dest;}//maxSource and maxDest will be used to perform the move. if (MAX_SCORE > black_best) { if (MAX_SCORE >= red_best) break; /* alpha_beta cutoff */ else black_best = (int) MAX_SCORE; //the_score } if (MAX_SCORE < red_best) { if (MAX_SCORE<= black_best) break; /* alpha_beta cutoff */ else red_best = (int) MAX_SCORE; //the_score } }//for ends return MAX_SCORE; } //end minimax I am unable to find out the logical mistake. Any idea what's going wrong?

• Setup shortcut keys not working

  - by Tim

  In my Ubuntu 12.04, in keyboard settings, I didn't find a shortcut key for restarting X, so in "Customer Shorcut", I set up Ctrl+Alt+Backspace for command sudo restart lightdm. But after that the shortcut doesn't work. Is it because it requires root privilege? Also I have a SysRq key on my keyboard, which I think to be the "Magic SysReq Key". My SysRq key is shared with PrtSc key (for screen shoot), and is in blue which means I have to press Fn key at the same time to invoke SysRq instead of PrtSC. But every time I press Fn+SysRq, it always shoots a photo of the screen, same as just hitting PrtSc i.e. without hitting Fn. I wonder how to use the Magic SysReq Key? Does it mean the shortcut has not been linked to any command that is supposed for Magic SysReq Key yet? PS: My laptop is Lenovo T400 and OS is Ubuntu 12.04. Thanks!

• Unity 3D not Working on Acer D270 w/ Intel GMA 3600

  - by amol.kamath

  I recently bought myself an Acer Aspire One D270 with the GMA 3600 graphics chipset thinking I would get some lovely graphics. However, I am stuck using Unity 2D and I cant figure out how to enable 3D. None of the fixes I have found so far have worked. Another effect of this is that I cant change the backlight brightness. So whenever I open the lid, looking at the screen is like staring into the sun. Is there a driver for it in the works? Does the 3.4 kernel support the chipset and most of all is there a way to fix this? Please help

• Google Goals process not working through similarly named pages

  - by David

  Well, I'm at a loss. I've ensured that my tracking script is in etc etc, and I've set up my goal and funnel path, but only the first step is ever being shown on the funnel. Goal URL: /checkout/checkoutComplete/ Type: Head Match ... but should this be /checkout/checkoutComplete/(.*) and set to regex rather because there are parameters after the main part of the URL (I thought that's what head match was for) Step 1: /checkout/ <-- required Step 2: /checkout/confirm/ both the above are valid and correct URLs for my domain. But for some reason, the funnel visualization shows entries into the first step, then an exits count that matches the entry count, including /checkout/confirm - but it doesn't go on to the next step! Perhaps I'm doing something obviously wrong...but I can't quite see it? Also, semi-related questions. Making a change to the funnel, does it only affect new incoming data? And how often does it update? Thanks in advance for your help.

• foobar.com working, but www.foobar.com not working?

  - by dpmattingly

  I am setting up a web site for a client. She is using GoDaddy for domain registration, and a hosting company I have never used before. After setting up the nameservers on GoDaddy's side, the address foobar.com (for example) is correctly directing to the new site. However, the address www.foobar.com is redirecting to a 404 page on the hosting company's side. I've been dealing with customer service on the hosting side, and they have told me various things including wait for DNS propagation (which has obviously happened since the 404 page is on their side), and to make sure that the nameservers on GoDaddy's side were entered in lower case instead of upper case (which I know doesn't matter since nameservers are case insensitive). I think I'm getting the runaround from the hosting company, but the client had signed up with them before I came to the project, so if possible I'd like to resolve this issue with them before we start treating it as a loss. Does anybody know what could cause foobar.com to resolve correctly but www.foobar.com to not resolve? How would I best be able to suggest a fix to this through the technical support channels of a hosting company?

• Cisco Linksys AE2500 wireless adapter not working

  - by makuto

  I have a Cisco AE2500 I've used with my laptop to get internet. I had to install the drivers by following this forum: http://ubuntuforums.org/showthread.php?t=1805830 But now the blue light on the adapter doesn't turn on at all, but ndiswrapper reports it is connected. I have no connection to the internet on my laptop, and the adapter doesn't show it's blue light on any of the USB ports of my computer or on the 4 port hub I have. Is there some way I can reset something so that the blue light will show again? I'm using Ubuntu 11.10 on a Dell Latitude D505 laptop. EDIT: I deleted and reinstalled the same exact driver and everything worked again.

• Working with QuickBooks using LINQPad

  - by dataintegration

  The RSSBus ADO.NET Providers can be used from many applications and development environments. In this article, we show how to use LINQPad to connect to QuickBooks using the RSSBus ADO.NET Provider for QuickBooks. Although this example uses the QuickBooks Data Provider, the same process applies to any of our ADO.NET Providers. Create the Data Model Step 1: Download and install both the Data Provider from RSSBus and LINQPad (available at www.linqpad.net Step 2: Create a new project in Visual Studio and create a data model for it using the ADO.NET Entity Data Model wizard. Step 3: Create a new connection by clicking "New Connection", specify the connection string options, and click Next. Step 4: Select the desired tables and views and click Finish to create the data model. Step 5: Right click on the entity diagram and select 'Add Code Generation Item'. Choose the 'ADO.NET DbContext Generator'. Step 6: Now build the project. The generated files can be used to create a QuickBooks connection in LINQPad. Create the connection to QuickBooks in LINQPad Step 7:Open LINQPad and click 'Add New Connection'. Step 8: Choose 'Entity Framework DbContext POCO'. Step 9: Choose the data model assembly ('.dll') created by Visual Studio as the 'Path to Custom Assembly'. Choose the name of the custom DbContext, the path to the config file, and assign a name to the connection that will allow you to recognize its purpose. Step 10: Congratulations! Now you have a connection to QuickBooks, and you can query data through LINQPad.

• 50-synaptics.conf options not working

  - by djeikyb

  How does Ubuntu come up with the default synaptics settings? I've got Ubuntu Netbook 10.10 installed on an Eeepc 900. Out of the box TapButton2 was set to 3, and TapButton3 was set to 2. I have several custom synaptics settings I want as system wide defaults. Right now I use a script with synclient commands I have to run every boot or wake. Pita. It used to be everything went in xorg.conf..which no longer exists. I'm trying to learn the new way, which is apparently conf files at /usr/share/X11/xorg.conf.d. I edited 50-synaptics.conf to look like: Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "LockedDrags" "1" Option "TapButton2" "2" Option "TapButton3" "3" EndSection But my next X session (startx -- :2) doesn't have the options configured.

• Unity Search Not Working

I also followed this guide: http://www.webupd8.org/2011/04/how-to-reset-unity-launcher-icons-or.html Alt+F2 does not work. The packages unity-place-applications and unity-place-files are installed.

The system (i assume boots into ubuntu) but I got no way of going onto the x or nvidia settings to change my display to external monitor EDIT well I booted into terminal using control shift F1 i think, and now I'm trying to reporgram x.org, but strangely it seems bland with not a lot of settings in it EDIT 2 xrandr returns "Can't open display" EDit 3 after some messing around with xrandr and xinit ... my x.org only displays one monitor instead of two in its settings although both, i.e. the laptop and external screens are both connected. EDIT 4 it seems that x.org now has a "screen" and "monitor" section, I can't seem to be able to boot linux into monitor. I get a "Monitor is not a valid keyword" in this subsection

• Giant battery consumption with dual graphics solution (only i-gpu working)

  - by Noel

  I use a Laptop with Intel Core i7 SandyBridge and integrated Intel HD3000 graphics as well as a Nvidia Geforce GTS 555M. So far, I got the impression my Laptop was running with the Nvidia graphics adapter only because the fan was always running on highest speed (and loudest noise) and it was getting very hot even when doing nothing. Also the battery is empty after ~40-50 minutes (while having ~4-5 hours with Intel graphics in Win7). Since this can't be healthy I wanted to switch to the integrated graphics instead. I was fairly surprised when the System Information showed me that the as graphics adapter I use "Intel M". Why is my battery empty so fast with Ubuntu? Without using the NVIDIA graphics adapter? Summary: I DONT WANT to use the Nvidia graphics adapter (OPTIMUS), I just want the Intel solution. As I have understood, the Intel solution is running already, emptying my battery 10x as fast as Win7. What is wrong? Any ideas?

• Why can't I get a working session with vnc4server

  - by ysap

  We have a couple of (identical) Ubuntu 11.10 machines, configured with gnome-classic, which we use as remote servers, and let our clients log into personal user accounts we create for them using vnc4server. We configured all the machines in the same way, following a short manual we compiled, describing how to download, install and prepare a few tools and our software. The connection usually works fine, but today I set up a fresh machine, and experienced problems. After installing vnc4server, I ran vncpasswd and copied the following startup file to ~/.vnc/xstartup: #!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS gnome-session --session=gnome-classic & [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & Then, I started vnc4server and used two viewers (the Ubuntu Remote Desktop Viewer and Windows RealVNC Client) in two other machines, but instead of getting my desktop, I see an empty window with a grey-ish background pattern like this: and the cursor is a bold X. What is wrong with the setup and why don't I get a remote session as expected?

• Unity Desktop not loading and ccsm method not working

  - by slimy-spork

  I installed Ubuntu 13.04 x86_64 on my HP Pavillion DV7-6c60us. It installs fine and works until I update. I run the software updater and reboot as it requests after. When my computer comes back on I get the desktop background but the rest of the Unity desktop doesn't load. I've tried the ccsm method and re-enabling but it just de-enables itself. I've also tried installing the gnome desktop but that does nothing for me either. I really want to switch to Ubuntu but this is causing issues. P.S. I've also tried using 12.10 and 12.04 with no dice.

• Firefox: middle mouse button stopped working

  - by diversario

  In Firefox, middle mouse button/wheel has been assigned "Open link in new tab" action for a while now, by default. Since I ran Software Update tonight, this action doesn't work in Firefox anymore. To be specific, middle mouse click doesn't open links anymore. At the same time, it closes tabs just fine (middle-click a tab == 'Close tab'). I don't know the update details, but I remember that Firefox update was there among other things. I tried running Firefox with a clean profile and middle button did work there, so something must've changed with existing settings.

• Getting Unity 3D working on legacy Nvidia card

  - by user69545

  I installed the latest nVIDIA drivers for my FX5500 card. I understand that the X server version does not officially support this driver or card but was wondering what I can do to get compiz running. I have researched for hours on this issue but cannot come up with an answer for myself. I might be doing all this for nothing but I wanted to at least try. Here is the output of my test: mike@mike-linux-box:~$ /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.35 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no So I was wondering what is the "Not Blacklisted" test? Is this the Nouveau Blacklisting? nVIDIA driver did that automatically. Does this need to be removed? Any help would be appreciated. I just want to run compiz effects. Thanks.
