• Not-So-Well-Known features of Ubuntu

  - by Khaja Minhajuddin

  Ubuntu always surprises me by making things easier in unexpected ways. But, it isn't always obvious, For instance When I was looking for a tool to RDP into windows, I found that Ubuntu already has an pre-installed app called Terminal Server Client which has this functionality. I am sure there are many such hidden things which are not known to the average user. This thread could be used to expose these little gems. EDIT: Maybe the choice of my words was wrong, Are there any things which you found were not very obvious?

• GNOME 3.2 Menu Not Loading

  - by chazdg

  Gnome 3.2 Menu is not loading. I wanted to add a minimize and maximize to the right of my windows. So I did the following: gconftool-2 --set /apps/metacity/general/button_layout --type string "menu:minimize,maximize,close" logout and login that it per the instructions of this website: Instructions I logged out and back in and that was it. No menu. Help!!! By the way, there is a fix on this website to restore Gnome. However it did not work. Another odd thing was that Gnome Tweak Tool is black under the Shell Extension tab.

I don't have to press any key or use mouse, it logs in automatically. But Its not working when keyboard is not connected. OS boots and stops on login screen. I can't connect keyboard in final kiosk hardware installation.

• Why not expose a primary key

  - by Angelo Neuschitzer

  In my education I have been told that it is a flawed idea to expose actual primary keys (not only DB keys, but all primary accessors) to the user. I always thought it to be a security problem (because an attacker could attempt to read stuff not their own). Now I have to check if the user is allowed to access anyway, so is there a different reason behind it? Also, as my users have to access the data anyway I will need to have a public key for the outside world somewhere in between. Now that public key has the same problems as the primary key, doesn't it?

• Google is not indexing my entire site despite having a sitemap

  - by Anusha

  I have an e-commerce website www.beyondtime.in. I have been constantly monitoring Googlebot crawling on my website and my webmaster account. Lately, I have found two issues that I have not been able to understand. 1.) The Google Bots have been only crawling www.beyondtime.in/telecom.php when the URL is not even valid. What needs to be done to let Google crawl other pages of the website as well? 2.) The second question is about the Google Webmaster account, where I've submitted my sitemap with 227 URLs. Out of that, only 156 have been indexed. None of the images of my website have been indexed by Google.

• Dual Screen with 12.04 ATI randr extension is not present

  - by Trevor Pearson

  Here's my problem I have two screens. One is a 22"led monitor and the other is 42 inch led tv. In windows 7 I run xbmc on the second monitor.

• Software center is broken and can not be repaired or reinstalled

  When I open the software center, I am told that I can not use it, for it is broken, and needs to be repaired. First I try to do this automatically, as I was offered.

I've tried purging wine/* but that had unresolved dependencies as well. It's a giant mess.

• Bluetooth not really "turning on" on a Sony Vaio VPCEG

  - by marcioAlmada

  On a Sony Vaio VPCEG, bluetooth is not working properly: The gnome-shell bluetooth indicator (at the main bar) shows the bluetooth is on, but when I try to switch visibility on it simply doesn't turn on. When I open the bluetooth configuration dialog, the on/off indicator shows me the bluetooth is off. And when I try to turn it on it simply does not turn on.

• google analytics reverse transaction not working with sales performance

  - by prasad maganti

  We have google analytics account and trying to do reverse transaction. We have created a transaction on one date and reverse transaction on some other date. After transaction if we do reverse transaction it disappears from transactions list. Is it the expected behavior or abnormal behavior? But, if we check the same order data in sales performance, the reverse transaction does not reflects on when we created the transaction, it reflecting on when we made reverse transaction date. It should not be do like this. The reverse transaction should affect the same date on when we made transaction date.

• Not using nofollow for UGC links

  - by Noam

  My site contains many links that were user generated so I've added a rel=nofollow to them. I'm considering removing that tag at least partially, as these are most of my outgoing links and I've come to understand it isn't a good SEO sign to not have outgoing followed links. Although these are external sites, I have some data on the popularity and categorization of these sites. I'm trying to decide between two options: Removing the nofollow link for popular sites in most categories. Removing the nofollow for links that are in specific categories that represent the categorization I would like to achieve for my site. For example if this is a site about Basketball only remove the nofollow for links that are from sport sites. As these are both not exactly natural approaches, can this hurt me? Which option would you recommend?

• Android Java rectangle collision detection not working

  - by Charlton Santana

  I had been hard coding a collision detection system which was buggy. Then I came across using rectangles for collsion detection. So I put it all in and it does not work, I put a log in and it never logged. Note to Java programmers who are not Android programers: Android uses the word Rect instead of Rectangle. Code for Block.java: public Rect getBounds(){ return new Rect (this.x, this.y, 10, 20); } Code for Sprite.java: public Rect getBounds(){ return new Rect (this.x, this.y, 20, 20); } Code for MainGame.java: for(Block block : BLOCKS) { block.draw(canvas); block.rigidbody(); Rect spriter = sprite.getBounds(); Rect blockr = block.getBounds(); if(spriter.intersect(blockr)){ showgameover = 1; Log.d(TAG, "Game Over"); } } Is anyone able to help?

• Boot path not found, cannot start OS

  - by Dustin

  My desktop is 12.04 64bit, and it cannot boot from the hard drive anymore. When I attempt to it just is stuck on a blank screen with an blinking dash, and nothing happens. I checked with the bios trouble shoot for problems and it said that no boot path could be found. I do not know why this is happening, but need to fix it because it used to boot up normally. What I need to know is how to fix it. I can boot into a live DVD. Also, there were a few boots I would attempt to boot into a live USB, then it would boot to the hard drive, but that does not work any more. So with the live DVD (it is an 10.04 LTS 32bit), is there any means to correct the boot path from the live DVD? Thank you for your time and answers.

• Making dummy applications while not involved in LIVE work [closed]

  - by Ratan Sharma

  I know this is subjective but I am looking for some real time helpful points/advice here, which will be helpful for some to get motivated. In our company so many people are on bench(not assigned with real time work) and they do not want to experiment things by their own. What would be a good motivation for them to keep their learning spirit? I personally feel that one can learn and give more effort in live client work than regular practicing things and making dummies. Am I right here or it is just my thinking only?

• Not able to install ubuntu 12.10

  - by Janet

  When I try to install Ubuntu on my computer I get this error: /var/cache/apt/archives/compiz-gnome_1% 3a0.9.8.4+brz 3412-0ubuntu0.1_i386.deb and /var/cache/apt/archives/metacity-common_1% 3a2.34.8-0ubuntu4_all.deb Ok, since I'm not a whiz at installing linux or understanding it...When these two things popped up it stated that the file was corrupted and there were too many errors to complete the install. Now, does that help? I had Ubuntu 12.04 LTS on my computer and wanted to upgrade, now I have nothing on my desktop and when I tried to install by using my usb pen, nothing happen and I also have it on dvd and tried to install from that and nothing still happen. So maybe someone can tell me why it's not installing on my desktop? I have it on my laptop with Windows.

• CSS specificity: Why isn't CSS specificity weight of 10 or more class selectors greater than 1 id selector? [migrated]

  - by ajc

  While going through the css specificity concept, I understood the fact that it is calculated as a 4 parts 1) inline (1000) 2) id (100) 3) class (10) 4) html elments (1) CSS with the highest rule will be applied to the corresponding element. I tried the following example Created more than 10 classes <div class="a1"> .... <div class="a13" id="id1"> TEXT COLOR </div> ... </div> and the css as .a1 .a2 .a3 .a4 .a5 .a6 .a7 .a8 .a9 .a10 .a11 .a12 .a13 { color : red; } #id1 { color: blue; } Now, even though in this case there are 13 classes the weight is 130. Which is greater than the id. Result - JSFiddle CSS specificity

  Ubuntu 12.04 was functioning properly . Then after an update, some graphic elements stop working properly. I could not launch programs that has 3D elements. Work space switcher's window displays 2D window instead of a 3D like usual. In Details menu, the Graphic row is blank. I am using Intel GMA 4500MHD graphic card. I am guessing that the driver is not properly installed? Anyone has the same issue? Please help!

• PATH command not found

  - by joslinm

  Hi, I'm not experienced with PATH (Any good reference would be appreciated), but I made a mistake and did PATH=/google_appengine, which I'm assuming completely overrid PATH. Still, I restarted bash and echo'd PATH and found that the folders were back. mark@mark-laptop:~$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games However, when I then tried to append to it, I got an error that PATH wasn't found. I've looked around Google and couldn't find a good answer. Any help would be appreciated mark@mark-laptop:~$ PATH = $PATH:/google_appengine PATH: command not found

• Not able to suspend or hibernate

  - by Tim

  My Ubuntu 10.10 on my laptop Lenovo T400 is not able to suspend or hibernate. Whenever I click Suspend or Hibernate, the moon LED on the bottom of the lid flashes a few seconds, the screen quickly shows something like "some devices fail to suspend, error 5", and then the moon LED goes off and the display still has ambient light illumination. I suppose in suspend or hibernation state, the display should have no illumination, just like when the laptop is turned off, right? If I press any key, the unlock screen dialogue will pop out. I searched a little on the internet, and installed 'acpi-support' according to some advice but it does not help. Any suggestions to solve this problem? Thanks and regards!

• Git does not ask for passphrase during pull/push in terminal

  - by Damian

  I'm trying to use git from the terminal in my Ubuntu 12.04 desktop. My repository is hosted in Github, and I have the a key for my desktop. Whenever I do either "git pull" or "git push," a dialog box will pop up asking for my passphrase. This works fine if I type the passphrase correctly. However, if I'm connected to my desktop through ssh and do a git pull or push, the command does not prompt the passphrase and it outputs the following error: Permission denied (publickey). fatal: The remote end hung up unexpectedly This error makes sense because I'm not inputting my passphrase. So the question is, how can I get the passphrase prompted in the terminal? Thanks!

• Sound not working for uid=1003 but working fine for uid=1000

  - by Dirk Eddelbuettel

  Sounds works for uid=1000, but not for the main user on the system, running with uid=1003. Upon boot, the Ubuntu chime clearly plays. When the user is logged in, sound test shows no input device. I looked at several of the previous questions, added the user to audio, video, pulse, pulse-access --- but still no luck. To recap: This worked perfectly in 11.04, 11.10, 12.04. It works for the default user uid=1000, it does not work for the actual user. The differing group memberships are mainly for adm, admin, sudo and the like.
