• What is the sudo password after I deleted the password for the user?

  - by Ubuntunewbie

  To have an easier access to the computer I deleted the user's password so it is blank. But now I'm still asked to type in a password for sudo actions such as installing programms, etc. I know that this belongs to Ubuntu's outrageous security policy (which is why I use Ubuntu in the first place..) but I don't have any password to enter any more!! The old user password is not accepted and anything else (like just hitting enter) doesn't work either. I already tried the recovery mode (root shell) way passwd USER< but it replied that it can't access the password or it has no authority. Thanks in advance for your help!

• Regulating brightness using Fn-keys

  - by richter12

  I have a laptop with the newest Ubuntu-version (12.04). I want to use the FN-Keys to adjust the brightness of my screen, but it doesnt work. Normally it should be FN+left arrow/right arrow. However adjusting the volume with FN+ up arrow/down arrow works fine. I already searched for a few soulutions, for example tried to replace in the Grub-File GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor" or GRUB_CMDLINE_LINUX_DEFAULT="quiet splash cpi_osi=Linux" but it all doesnt work for my laptop. How can I fix this problem? Thank you very much! Richter

• I've got two technical degrees but little in the way of experience. How do I get into programming? [closed]

  - by Neonfirelights

  I'm looking for a job, I want to break into programming. I'm looking for the right sort of role and the right place to look for it; I would really appreciate input from someone with industry experience. I've got an excellent academic record: BSc Physics (2:1), MSc Computer Graphics, Vision and Imaging (expecting Merit) from two world ranking universities. I have advanced technical knowledge of C/C++ and Matlab and experience working with C# and VB.NET. Unfortunately I don't have much in the way of commercial experience; unlike a lot of people I know my under-graduate didn't come with a sandwich placement. Where can I go to break into the software industry?

• Why does Ubuntu Freezes on ASUS K42DY laptop with RADEON HD6470M Graphics Card?

  - by ix3

  Hi,I have an ASUS K42DY laptop with AMD Phenom II x2, 8 GB Ram , 500 GB Hard Drive and has a didicated ATI RADEON HD 6470M Graphics Card and I'm running Ubuntu 12.04 LTS 64bit on it. I have installed GNOME 3 and also followed this Make Ubuntu look like Mac OS X. I have also installed apps from the software center, getdeb & playdeb all of which worked fine. However, I noticed that Ubuntu freezes after inactivity let's say 1-3hrs. I have already set power setting to never standby or hibernate. This is completely annoying because all I can do is log-out via ctrl+alt+del or manually shut down and reboot my laptop. What should I do? By the way, this happens on all shells Unity, Gnome (even with the basic) and Cairo Dock.I set Swap Space at 8GB during installation. Any help will be appreciated. Thanks!

• How do I install latest NVIDIA drivers from the .run file?

  - by Shahe Tajiryan

  This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com. The installation needs the X11 to be shut down, so I log out of my account, then press CTRL+ALT+F1, then log in with my username and password, then run the command sh NVIDIA-Linux-x86_64-285.05.09.run in every possible way, I have even tried CHMODing the package with 777 permissions, but still I'm getting the sh: can't open NVIDIA-Linux-x86_64-285.05.09.run error. Any help would be greatly appreciated.

• How can I fix a shaky touchpad cursor in Ubuntu on my hp pavilion laptop?

  - by Vindiggity

  I recently installed Ubuntu 12.04 on my laptop and it works great, except after the initial reboot my touchpad cursor shakes violently when I hold my finger completely still on the pad.It works fine with a regular mouse plugged in. I couldn't find much scouting around the internet except that it might be that my touchpad doesn't have any dead zones? I am very new to Ubuntu and am fairly computer savvy, but I don't know a lot about using the terminal or anything like that, so if you could dumb down a fix for this as much as possible for me, I'd greatly appreciate it.

• When I boot it says "No any drive found" and turns off after upgrade from 9.10 to 10.04

  - by user797582

  I did an upgrade on the weekend from Ubuntu 9.10 to 10.04 (karmic to lucid). Now, when I restart my computer, it goes through the regular load screen showing my P5K Asus motherboard, just like before but instead of showing the Ubuntu load screen, it tries to start grub but fails and then says "No any drive found" and the screen goes black. I've tried changing the drive configuration in the BIOS to AHCI or RAID and that didn't work. I've tried disabling JMICRON but to no avail. I'm running out of options here. Any advice?

• Ubuntu 12.10 doesn't boot (installed with wubi)

  - by Luna Kiyiya

  Quick and simple, my ubuntu doesn't want to load after installing with ubuntu. Starting the computer, at the screen to choose your operative system, first shows an error that windows failed to start, and later asks me to choose between ubuntu and windows. If I choose ubuntu, the same error happens again and I return to the same screen. If I choose windows, windows just starts normally as it was doing before I installed it. How can I solve this?? Thank you for your attention... I really need some help :)

• Can't connect to or search wifi

  - by Mark

  I just installed the latest version of Ubuntu, I think it was 13. Something. Anyway I got it running and now I've been trying to connect to my wifi. No matter where I go I don't see an option for wifi. I looked on the computer and found some commands to use in terminal to run a scan for wifi networks but all of them returned the error "interface doesn't support scanning" if anyone could help that would be great...I can't do anything without wifi! Also I'm new to this so if you could give step by step directions that would help a lot. Thanks!

• "Adding Esperanto circumflexes (supersigno)" option has no effect

  - by Gardel

  I'm used to use the keyboard layout option to type the accentuated characters in Esperanto. This option is in System Settings Keyboard Layout Options Adding Esperanto circumflexes (supersigno) To the corresponding key in a Qwerty keyboard. It worked great but since I upgraded to Ubuntu 12.04, this option has no effect. I'm using Ubuntu in French with the keyboard layout French (variant) and Gnome-shell. I tested on another computer with Unity and there is the same issue. Is it a known issue? I did not find anything about it…

• Do I need to buy a graphics card with openGL? [closed]

  - by Greb

  I'm building my own computer right now, and I've found a very good combo deal on a graphics card with monitors. I will be using mostly Linux of course, but I'd like to be able to do some windows work as well. I will do some gaming, but mostly just graphical design with blender. So how important is it that my graphics card supports openGL? This is the deal i'm looking at: http://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.636041 Sorry if this isn't the correct forum for this. Please let me know if you know of someplace better I could ask this.

• Showing range on hexagonal grid

  - by user23673

  Here is the situation. I have hexagonal board,and a unit on it,with speed or move value 4.Diffrent terrain has a diffrent cost.When i click on the unit,game should show me a move range. My solution was to check each hex in range of 4,with A* pathfinding,and if path cost was less than 4 then this hex was in range.Finally game nicely show me range of that unit. My question is: Is there other solution to search for range on hex grids or square grid,because even if i am really proud of what i did in my solution,i think,it is a little to exaggerated?:)) What make me ask this question?I noticed that when unit speed is 4 or 6 or even 8,time to computing range for my computer was really good,but when speed was 10 and more i noticed that i needed to wait few second to compute.Well in real games i rather dont see something like this and my A* pathfinding is rather well optimized,so im thinking that my solution is wrong. Thanks for any replies.

• Ubuntu crashed while 13.10 was installing and now it doesn't detect my keyboard when I boot

  - by iirelu

  I was running the 13.04 to 13.10 installer, and it slowly caused Ubuntu to break down until eventually the installer itself along with Unity crashed, forcing me to Alt+SysRq+B. Now, when I try to start Ubuntu it doesn't detect my keyboard at all. It boots up completely fine apart from that bringing me to the 13.10 login screen. The backlight on my keyboard remains on but not a single thing works, not even SysRq. I was imagining that if I could run apt-get dist-upgrade it could finish the update, but I couldn't get that far.

• Can you run OpenGL 2.0 on modern machines?

  - by thePalindrome

  I'm looking to get into 3d with OpenGL, using SDL to help with other stuff. I found plenty of good tutorials (lazyfoo is a big one), but "Learning Modern 3d Graphics Programming" uses a newer version of openGL that I'm not able to run! I opened up OpenGL extensions viewer, and I can only run OpenGL 2.0, whereas most tutorials are in higher versions. I ask this because I've heard that just about everything in 2.* got depreciated in the newer versions, so I'm worried that my code might not work. I'm looking at a few other tutorials, but I'm so used to SDL that those just confuse me... So should I bother trying to do graphics programming now, or should I just wait until I can upgrade my computer?

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

• xset: unable to open display

  - by user287878

  for the longest time after about 5 minutes my screen would blank out. Now the screen will go blank after 5 minutes but then 2 seconds after that it will light up white and keep the laptop backlighting on. I didnt change any settings to my knowledge it just happened randomly after powering it on one day and has occurred since then. I wish to resort back to blanking the screen out completely since i leave this computer on all the time and its hard to sleep with a huge white light all the time. "xset dpms force off" just yeilds me ---- xset: unable to open display ""

• In some games, we just let the main() loop be the Player object or Table object?

  - by ????

  I was thinking that let's say if there is a game of Blackjack or MasterMind, then we should have a class called Dealer or ComputerPal, which is how the computer interact with us (as a dealer for Blackjack or as the person giving hints for MasterMind). And then there should be a Player object, and the way to play one game is aPlayer.playGame but I noticed that a book was just using the main() loop to act as the player (or as the Controller of the game), calling the Dealer methods to dealer the cards, ask for player's action, etc... 1) Is this just a lazy way to model all the proper objects? 2) If more objects are to be added, who should call the aDealer.dealCards and then ask for aPlayer.askForAction? (because it is strange to let the Player handle all the logical steps). Should there be a Table object that handle all these logic and then to play one round of game, use aTable.playGame? What is a good object design for such game?

• What should I learn next?

  - by Krysten

  I am a CS major. I've taken 2 courses in C (Intro to C and CS1) and 1 introductory course to OOP with Java. I really like Java and feel that I have a firm understanding of OOP concepts. I am really interested in web development and would like to learn a programming language that can be used to build dynamic web applications. My question is what language should I learn? I've narrowed it down to python or ruby. Also, I want to learn a programming language that will help me get a job upon graduating. So essentially, I will use this particular language to build applications that will help me get a job in the future.

• How is this paradigm/style called?

  - by McMannus

  I have the following situation: I'm developing an add-in for a UML modeling tool. The models that can be created by the user are stored inside the main application and a limited access to the models is given through its API. However, the add-in has a lot of callbacks for events that are triggered by the main application, when changes to the model occur by the user. Since the models are already stored once in the main application, I considered it not practicable to duplicate the models in the add-in, which leads to the fact that I have only behavior in the add-in, rather than having a state. This behavior is mainly expressed by static functions, that are organized in functional cohesive classes. The callbacks for the events have always references to the model elements relevant for the specifc event that ocurred. First, it seemed to me that this is a procedural style in general, but procedural style doesn't consider events/callbacks, so this boils down to the question. How is this programming style called?

• Wireless mouse temporarily freezes when resume from standby

  - by R Pennese

  I have been getting a very annoying problem since recently in Ubuntu 12.04, probably due to another update that did more bad than good... When I resume from sleep on my Lenovo Thinkpad T420, my wireless laser mouse (Logitech M705) freezes at regular intervals (15.20 seconds) for 5 seconds then works again. This happens regardless if the computer is on battery or on AC power. How do I debug this? I am getting tired of the fact that my system gets more and more unstable over time while it should be the opposite...

• My ubuntu 11.10 gets weird lately

  - by The questioner

  I have quite a lot problems lately(about 2 weeks) running Ubuntu 11.10. First, flash playback in chrome hangs and lags all the time. While in Firefox is better, but still lags. Playing video files in the preinstalled Movie Player lags too. Second, I've turned automatic on and in some occasions, after I switched the computer on and successfully loaded the desktop, however, in just a minute or so, the screen just got black out and directed me back to the login page. I thinks there are bugs, please tell me how to correct those. Sysinfo: CPU: i5-2400 MB: GA H61M D2P B3 (no video card) Drive: Intel 320 40GB Thanks. p.s. should I upgrade to 12.04??

• Good source for interview-style coding problems for entry/intermediate developers?

  - by soster

  I have taught myself to code over the past few years and do not have a computer science degree. As a result, I lack experience from many things, such as the basic homework/test questions many CS graduates take for granted. I recently had a tech screen interview where I fumbled and struggled to finish a (relatively) common question, I believe due to this inexperience. My question to all of you is this: do you know a good source for a bunch of these problems that includes answers, for an entry/intermediate developer who is trying to gain coding problem solving experience? The ones I've been able to find on the internet are for coding teams, so they're a bit too complicated for me. Thanks so much in advance.

• Limitation of high level languages? [closed]

  - by user1705796

  My question may look bit philosophical and nonsense! But I need to know kind of instructions those are not well suitable in high level languages even in c? Or rarely use in the development of software? Like read/write content of CPU registers may useful in debugging programs. And access to cache memory required when developing OS (maybe I am wrong at this point). Is this kind of instruction available languages like Java, Python, C? I also have a second question: And Why all high level languages not having same uniform syntax; at-least same standard library interface name? In python there is and. Or operator is almost same as && and ||. I think Python is developed after C but space indentation is compulsory in Python. Why Python does not use brackets {}. I already know this question going to be highly down-voted.
