• Changing OS from Windows to Ubuntu

  - by Shadowinnothing

  So my computer has 2 operating systems on it, Windows 7 and Ubuntu 12.04. When I downloaded Ubuntu i had a ton of trouble booting windows 7 up again, then I downloaded GRUB and switched my default OS back to Windows. Sadly though, I'm trying to get into writing php with Apache. I Downloaded WAMP (windows Apache MySQL php) but for some reason, php doesn't work. I though i would try downloading LAMP (Linux apace MySQL php) but whenever I boot up my PC, I don't get a chance to enter the Ubuntu OS. How could I get back to running Ubuntu? Actually, it doesn't prompt me for a boot menu or anything. It just goes straight to the windows symbol

• Where in a typical rendering pipeline does visibility and shading occur?

  - by user29163

  I am taking a computer graphics course. The book and the lecture notes are vague on the on the order of flow between the different steps in the rendering process. For example, if we have specified a view in a scene, and then want to perform a projection transformation for that given view, then we have to go through a sequence of transformations. In the end we end up with a normalized "viewcube" ready to be mapped 2D after clipping. But why do we end up with a cube (ie 3D thing), when a projection results in projecting the 3D objects to 2D. (depth information is lost?) The other line of reasoning is that all information further needed is stored within the "cube" and that visibility detection and shading is performed with respect to this cube and then we perform rasterezation.

• How can I remap my keys to act like the Macintosh keyboard (like hold alt l + l click = r click)?

  - by jaorizabal

  I want my keyboard layout to act like a Macintosh keyboard. It's hard to use my computer after years on a mac. I want to disable my right mouse click, and replace it with alt + right mouse click. The alt key will also act like ctrl. I want my left ctrl to be the HUD key. I still want my super key to be the same. Can someone please make a script, or point me in the direction of a program to do all this with ease. If you were to make a script/whatever, can you please make one what will reverse all keyboard changes in-case I feel that it is not the same. I will add to the post if I miss anything. Thank you.

• Sound not working

  - by Jason

  I am new to ubuntu, but really enjoy it. I do have one issue with setting it up on my computer. It is a GoBook XR-1 and everything works perfectly except there is no sound. I've searched and tried everything that I can think of, even uninstalling ubuntu and trying Windows to see if the speakers worked. I found out that it wasn't the speakers or any hardware issues. I tried to download the Realtek drivers, but still no success.

• No sound in World of Goo?

  - by user37805

  I installed WorldOfGooSetup.1.41.deb and it didn't work. There was a segmentation fault error (core dumped) in terminal. I fixed that with: sudo cp /usr/lib/x86_64-linux-gnu/libvorbis.so.* /opt/WorldOfGoo/libs32 sudo cp /usr/lib/x86_64-linux-gnu/libvorbis.so.* /opt/WorldOfGoo/libs64 That error is new for me as I have never had it before with previous releases of Ubuntu. The game starts now but no sound effects or music is played. I can hear music with my computer, videos, etc, so it is not a volume control problem. I am using ubuntu 12.04 final release.

• How to begin serious game development (in C++) [closed]

  - by Rondogiannis Aristophanes

  I would like to start developing games. I have tried before Game Maker 8, which was a very easy way to start creating games, if you were new in game development. Then, I tried Unity 3D, which was a much more serious and complete tool to create computer-games, and required some experience. And now, I would like to start creating games, and don't use any special environment or developer, but just code (in C++ preferably). So, here is my question: from where should I begin, if I would like to start programming games? Thanks in advance. Note: I work in ubuntu 10.04, I can also use windows 7, but I prefer ubuntu.

• 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 ""

• 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?

• 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 :)

• 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.

• 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!

• "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…

• 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.

• 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.

• Where can I find a collection of photorealistic scenes? [on hold]

  - by emchristiansen

  Where can I find a collection of 10-100 3D scenes with photorealistic levels of detail? For example, the scene rendered here contains photorealistic detail. Note I want the underlying object models, textures, etc, not final renderings. I'll be using these scenes to test a computer vision idea. BTW, this is a reposting of this question. I wasn't able to find a Stack Exchange site that is perfectly suited to the question, but as this is a modeling and rendering question, I'm hoping it is a good enough match for the venue.

• 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?

• 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!

• 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?

• 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?

• NetworkManager refuses to manage my WLAN interface

  - by user104167

  I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C. The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly. Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot. Therefore I edited /etc/NetworkManager/NetworkManager.conf to set: [ifupdown] managed=true When I rebooted NetworkManager, the problems started: - The NetworkManager tray applet changed from saying device not managed to device not ready - I lost all internet connectivity as wlan0 would not associate to the Access Point - if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable. However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.

• Dual boot w/ windows 7

  - by Aduff

  So my PC had windows XP and Win 7 on it and I went into the XP partition and installed Ubuntu 12.10 over it being sure to use 90% of the XP partition for the / mount and 10% for the swap. It installed but when I boot the computer it doesn't give me the option of choosing between 7 or Ubuntu, just booting right to the Linux distro. Should I have installed it in 7 over the XP partition? I can see the drive in Ubuntu that contains all the 7 files. How can I recover my 7 access?

• Dual monitor with different resolutions problem

  - by Mackemint

  I'm on an LG R405 with a PM965 chipset and a NVIDIA GeForce Go 8400M GS gaphics card. I'm trying to use an external monitor (Benq senseye3 G2222HDL) through a VGA out port. All was fine when installing except for the screen layouts were flip-flopped (computer defalut setup so external monitor was to the right instead of left). When I moved the secondary monitor to its real position in the setup, I started getting strange problems. I loose representation of large portions of the screen, on both screens, and have to reboot. If I plug the monitor in after rebooting I get more problems than when booting up with the monitor already plugged in, but in both cases I can barely see what I'm doing. Please advice! Regards /M

• 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??

• Make recovery disk for customers

  - by alexander7567

  I hear about other computer shops that sells customers recovery disks that they have created. I'm assuming all that they do is make a image and uses an automation script that allows this to be done. I have seen where clonezilla does this, but it has to be the same HDD size or they might have problems down the road. Is there any other freeware that I could do this with that allows you to use on any size disk. Ghost is really good for this because it automatically fills up empty space with the partition and never needs any user input or "Expert Mode" like clonezilla. But it is not freeware.
