• Recent Ubuntu update prevents MySQL root access

  - by Rhys

  I recently updated my Ubuntu (10.04 LTS) server (apt-get update, apt-get upgrade), and everything works fine, apart from the root access to my MySQL database. phpMyAdmin, CakePHP, and essentially all connections return similar access errors. For example, PMA returns 'Connection for controluser as defined in your configuration failed.' I have tried to find similar examples of this instance, but cannot find assistance in what configuration I should be changing to restore root log in access. The same issue has occurred on two servers. One has additional users so I could get around it, but the other is a new development server with only root MySQL access, so I am stuck on how to resolve this.

• First time using Ubuntu, need help with drivers!

  - by Nick

  I have just successfully built my first computer last night. I went through the boot menu and got Ubuntu 12.10 installed properly and everything. My question is...now what? There has to be some sort of drivers I need to install right? I can't connect to wi-fi or anything of that sort. I have an ASUS motherboard, model number M4N98TD EVO , and an NVIDIA Geforce GTX 650 grpahics card. I guess my main question is, can someone run me through step by step what I need to do after I install Ubuntu?

• 14.04 Chinese Ibus Input - No Options

  - by RhZ

  getting my new 14.04 rig going ;-) Pretty happy with it, everything seems to be working great. For Chinese input, however, having a problem. I went through the typical steps, open language in settings, let it install some stuff, then add Chinese and choose Ibus. Then, after logging in and out, I see the language icon in my system tray. However, when I go to add the Chinese into Ibus, it only lets me choose "Chinese", which isn't an input method. It should give me a bunch of choices like pinyin, bopomo or whatever, I only use pinyin so don't know those names. I saw someone online had a little command which helped people with similar problems, but it did not work for me, even after a re-start. So, anyone got a solution? Edit: Here is what it looks like, just "Chinese" in the list, when there should be a bunch of input options like pinyin, potomofo, and so on.

• Set up Java path for terminal

  - by Xsteen

  Trying to set up a path for the terminal. I already have Eclipse running great. Dual os between windows 7 and Ubuntu 12.04. However, I would prefer to run everything out of Ubuntu, just not very experienced and all the forums I have searched are not giving me the step by step answers I need to make this happen. I included a screen shot of some information about my version etc. Any help would be greatly appreciated at this point I've put 10+ hours into this and this is my last resort.

• Ubuntu desktop and dash problems

  - by user170163

• Unity3D problem. Bullets fall down instead of flying like they should

  - by user2342080

  I used this tutorial as a reference. http://www.youtube.com/watch?v=3L8eaoyZ0Go My problem is that whenever I play the game, EVERYTHING works but the bullets. It just falls down instead of flying forward. This is the flash version of the game: http://v1k.me/swf/ Can some one help me out? Should I upload the project? This is my "Shoot.js": public var bulletPrefab : Transform; public var bulletSpeed : float = 20; function Update() { if(Input.GetMouseButton(0)) { if(bulletPrefab || bulletSpeed) { var bulletCreate = Instantiate(bulletPrefab, GameObject.Find("SpawnPoint").transform.position, Quaternion.identity); bulletCreate.rigidbody.AddForce(transform.forward * bulletSpeed); } } }

• The answer to the unfathomable question: what is meaning of error value 2147943645?

  - by Jim Lahman

  I scheduled a task to perform a windows backup of a single disk on the my server.  When I tested it, the task ran successfully – no problems, no errors; just as I expected.    However, when the task ran as scheduled, it failed with error value 2147943645.  I wondered was this the answer to life, the universe and everything in it?  No.  That is 42.    After doing some research and reviewing the task configuration, I realize that the task will only run if the user of logged on:   So, this was the answer!!  I have to configure the task to run whether the user is logged or not.  Or, else I’ll get that nasty error value.

• Laptop works fine with ac adapter, hangs after login screen using battery

  - by tavoton

  I did an Ubuntu 10.10 Desktop Edition clean install (amd64 version) on a notebook Medion Akoya E1311. With AC adapter everything works fine, but using battery, it hangs after login screen. I can type login, password too, and I can press login button. But then I can see mouse cursor and lower task bar, not upper, and nothing works. The only thing I can do is login on a terminal with ctrl+alt+F1, this is ok. Nothing seems alive on Gnome except mouse cursor. The only thing I did after Ubuntu fresh install was donwloading driver for RTL8191SE from Realtek web, because WiFi didn't work, now works fine, with ac adapter of course. Hardware is a Notebook Medion Akoya E1311 AMD Sempron 210U 1 GB DDR2 ATI RS690M (Radeon X1200 Series) Western Digital 160GB wireless RTL8191SEvB ethernet RTL8101E/RTL8102E

• HTML background-size:cover with floating objects

  - by Mikhail

  I have a trivial page with body having an image background, with background-size:cover. I set html { height:100% } to fill up the entire page regardless of the content amount. Up to this point everything worked as expected. I've added a div and set position:absolute; right:0; width:200px; This, again, worked as expected, until I added content. When this div is populated so much that the contents take up more space than the height of the page, the scroll bar appears. Scrolling down reveals that the background image does not actually cover the entire page. This is due to the fact that my div is taller than 100% of the HTML height. How can I address this?

• Unable to login following permission changes in device manager (11.10 + Gnome)

  - by Symanuk

  (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers

• How to give control over keyboard back to X server after Alt + SysRq + R trick

  - by Øystein Tråsdahl

  Situation: an application freezes the X server and no keyboard input works. So I use Alt+SysRq+R to take the keyboard out of raw mode (make the kernel take control of the keyboard away from the X server). I can then type Ctrl+Alt+F1, kill the bad processes, and everything works again. So far so good. But the keyboard is still in the hands of the kernel, making Alt+Left/Right shortcuts for Decr_Console/Incr_Console. This is annoying, and I want to give control over the keyboard back to the X server. I have tried typing Alt+SysRq+R again, this does not switch things back. I have also tried the command kbd_mode -u, but nothing changes. Any advice?

• Linux Mint Cinamon 17 Qiana, Xfce desktop background problem [on hold]

  - by Serj

  I've installed Xfce4 on my laptop which runs Linux Mint 17 with Cinamon default desktop. Everything works OK and I customized my lightweight Xfce, like change menu location and desktop background that it is similar to my Cinamon desktop and used it for a while. Suddenly after last restart my desktop background becomes black and there is no option for desktop background change when I right click on desktop. I should mention that xfdesktop & didn't help, which tells it's already running. Some icons like Computer, Home and Oracle VM that was already there is showing, but my Trash or other icons did not. I've tried everywhere in xfce4-settings-manager but could not get my desktop background back

• remove ssl from Google search results

  - by user73457

  I am the webadmin of a WordPress site that serves up http pages statically. The problem is that some of the pages are shown as https in Google search results. For instance, if the search term "Example Press Kit" is entered the search result site link comes up as: https://example.com/presskit/ We don't have a site ssl certificate, so surfers are being bounced. I have tried everything. Most recently I created a new website in Google WebAdmin for the https version of our home page. Then, I added sitelinks that should have redirected site links intended for https://example.com/* to http://example.com/*. But it doesn't work! Google still shows a dead link to http://example.com/presskit. I didn't think dead links lasted very long on Google results, but there they are, two weeks later. Any ideas?

• Crontab opens as blank page, cannot save

  - by Sarah

  I am really not familiar with linux, and only started using it recently, so be patient with me. I am trying to control a camera on regular intervals through a script that is called upon in the crontab. When I start up the computer, I can open crontab, edit and save, and everything is executed correctly. However, I can never open crontab a second time, unless I restart the computer first. If I type crontab -e, I get a blank page, located in the /tmp directory. I can enter my commands in there, but cannot save it. I don't know if this is relevant, but when I try sudo crontab -e, I get something like "no cron installed for root". Any help is really appreciated! Sarah

• Batching dynamic sprites in OpenGL

  - by Aaron

  I'm trying to wrap my head around how batching is done in a 2D sprite-based game. My understanding is I'd get the vertices that represent each sprite I want to draw and stuff them all into a single mesh. That way I'd only need a single draw call to render everything. Does this apply when the sprites I render are different between frames, or when some sprites are moving? Because it sounds like I'd then have to recreate my batch mesh each frame, using either glDrawArrays/glDrawElements or a streaming VBO I assume. Does this sound correct?

• MCP 1.7.10 Java class navigation

  - by Elias Benevedes

  So, I'm new to the Minecraft modding community and trying to understand where to start. I've attempted to do it before, but dropped it to the complexity of starting and the lack of a site like this to help (Mind that I'm also semi-new to Java, but have worked extensively in Javascript and Python. I understand how Java is different from the two). I have downloaded MCP 9.08 (Decompiles 1.7.10), and decompiled Minecraft. I'm looking to mod client, so I didn't supply it with a server jar. Everything seemed to work fine in decompile (Only error was it couldn't find the server jar). I can find my files in /mcp908/src/minecraft/net/minecraft. However, if I open up one of the classes in, say, block, I see a bunch of variables starting with p_ and ending with _. Is there any way to make these variables more decipherable, to understand what's going on so I can learn by example? Thank you.

• Grub rescue after installing Ubuntu from USB

  - by Victor Suarez

  I have Windows 7 installed in my internal HDD and wanted to try out Ubuntu so I have an USB to put Ubuntu LiveUSB on and installed Ubuntu on a external HDD and everything worked out fine. Now the problem. If I remove the external HDD and try to boot Windows normally it shows the grub rescue screen. The only way to boot into Windows is by having the external HDD attached. Is there any way I can make it so I won't have to have the external HDD attached to be able to boot my Windows 7?

• How to convert an XFS file system to HFS+

  I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but !

• How can you become a real programming polyglot?

  - by Yob

  I work as a Java programmer, but C and C++ were always my favourite languages during studies. Unfortunatelly I don't have an opportunity to work with them as often as I would like to. As a result I sometimes get realized that I don't remember something quite important (today example: inherited protected members cannot be accessed in derived class constructors). The other example could be Python and Haskell which I enjoy using but don't use everyday. I got an idea to write my own wiki with easy to forget things (e.g. bash tricks & tips) but I find no sense in writing there everything I can forget about coolest programming languages. I know that the best way would be having a side projects (I want to start working on some C/C++ open source project after graduation), but currently I have to write my graduation thesis and work so I merely don't have time to do this. How do you stay sharp in languages that you don't use everyday?

• Why doesn't 12.04 recognize my ATI Radeon X300SE graphics card?

  - by Nomad Zero

  So far everything including the BCM4321 card is working, however, the OEM ATI Radeon X300SE (RV370) is not recognized. When I go into system details the card comes up as unknown. When I run lspci the card shows up as: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: Advanced Micro Devices [AMD] nee ATI RV370 [Radeon X300SE] I have attempted check Additional Drivers but the card does not show up as needing a driver. So far this is causing the system to run warmer as the processor is doing a bit of the work to run Unity and any full screen videos tend to be rather choppy. Is there an available driver that will fix my issue and what is the install method? I am not scared to run a terminal so no worries there, as long as I have instructions, I can find my way. I am running under 12.04 LTS Kernel 3.2.0-25-generic-pae

• New Bing Maps

  - by MikeParks

  Normally I don't stray too far from Programming and TFS on my blog posts but I'm just really impressed with how much Silverlight has improved Bing maps. I use to be big on MapQuest, then hopped over to Google, but now the new Bing Maps have everything I need. The two coolest features are right on the main page. All you have to do is go to http://www.bing.com/maps/explore/, enter your city and hit enter in the search box, then look in the lower left corner under the EXPLORE section. Check out the "What's nearby" and "Restaurants" links. The best part is, if you're interested in doing any Silverlight programming, they have a Bing Maps Silverlight Control Interactive SDK. I was thinking about coding something....but they've pretty much got it down :) Pretty impressive stuff.

• What are the pro/cons of Unity3D as a choice to make games?

  - by jokoon

  We are doing our school project with Unity3d, since they were using Shiva the previous year (which seems horrible to me), and I wanted to know your point of view for this tool. Pros: multi platform, I even heard Google is going to implement it in Chrome everything you need is here scripting languages makes it a good choice for people who are not programming gurus Cons: multiplayer ? proprietary, you are totally dependent of unity and its limit and can't extend it it's less "making a game from scratch" C++ would have been a cool thing I really think this kind of tool is interesting, but is it worth it to use at school for a project that involves more than 3 programming persons ? What do we really learn in term of programming from using this kind of tool (I'm ok with python and js, but I hate C#) ? We could have use Ogre instead, even if we were learning direct x starting january...

  I set up dual boot on my extra pc last night. first installed windows 7 and that went just fine.

I then installed and everything seems fine except when it's booting, the purple screen is broken. should I try to redownload and re install?
