• How many vertices are needed to draw reasonably good-looking terrain?

  - by bobbaluba

  I have some pretty expensive code in my terrain vertex shader, and I am trying to figure out if it will still be fast enough. I haven't yet developed a level-of-detail system for my terrain rendering, but I can easily benchmark my code by just drawing mock triangles. My problem is, how do I know how many vertices to test with? Are there for example rendering engines that will tell me how many terrain vertices are currently on-screen? Or maybe it is possible to create a formula that will give me an estimate based on screen resolution?

• Ubuntu won't start

  - by Tomas

  I've had Ubuntu installed, using WUBI, for some time now - a few months or so. It's worked fine until now, allowing me to login, use it's features etc... Two days ago, I turned on my computer and started Ubuntu. It loaded the GUI fine but just showed the loading screen and even after waiting 10 mins on this screen it still wouldn't show me the login page. I am enthusiastic about web design and development and all of my work, along with my portfolio is stored in Ubuntu. Cheers, Tomas EDIT: I am using 12.04 LTS.

• Cannot boot Ubuntu 12.04 on Lenovo V570 fresh install

  - by Jonathan

  I just did a fresh install of Kubuntu 64 bit 12.04 (from the DVD) to a Lenovo V570 laptop. I did a dual boot install with Windows 7. I used the boot layout leftover from Linux Mint 12 (which was working). The installation finished with what seemed to be a success. However, when rebooting, I get this error: GRUB: “invalid arch independent ELF magic” after install on SSD Then I did grub-install and update-grub (I didn't install grub-efi, so maybe this is the problem?) Then I got "unknown filesystem error" at the grub prompt. Desperately, I gave /boot the bootable flag. Then on a reboot,... I got some strange screen with the letters PXE. It flashed momentarily, too fast to read, and then the computer jumped to a screen which asked me from which drive was the boot desired to be. As of now, I have no idea what I am doing.

• Brightness issues on MSI GT683

  - by Mitu

  I'm experiencing brightness related issues on my MSI GT683 (Intel Core i5-2410M, nVidia GeForce GTX 560M, Ubuntu 12.04 LTS x64, nVidia driver version 295.40). To start with, when I open brightness settings, the slider is working incorrectly - screen is the dimmest on about 1/3 of a bar, moving it to the left side increases brightness. Next, while pressing the keyboard buttons (Fn+up, Fn+down), brightness changes incorrectly - sometimes 2 steps up/down, but sometimes it's totally irregular - ex. in order to set the lowest brightness, I have to set the maximum, then hit Fn+down, then Fn+up. (after 2 moves from 8 to 2... What's even more strange, while changing brightness from keyboard on boot and on login screen, it works perfect. Tried adding acpi related switches to GRUB, but the brightness settings wouldn't work at all. Any help appreciated.

• cross resolution level design advice [on hold]

  - by Mike

  I was looking for some beginner advice regarding level design across multiple resolutions. I believe the answer is likely "it depends", but any input from anyone with real experience is very appreciated. Basically, I am building a 2D Super Metroid type game. If rooms/levels are to be a tiled grid, what are some general best practices for designing rooms when taking into account different resolutions? Since more or less tiles could fit vertically on a single screen depending on the resolution, is it better to design towards possibly having more of the room visible depending on the screen (with a bare minimum needed for gameplay), or should I fix the design at a certain tile height and scale the graphics?

• Vdpau performance in Precise with Unity 3d

  - by bowser

  vdpau seems to be broken in Precise under Unity 3d. CPU usage ranges around 50-70% for 1080p movies while same movies utilizes around 5-10% in Natty with vdpau enabled (under Unity3d) The card is Nvidia G105m. It doesn't seem to be a Nvidia driver problem because in gnome-shell everything works as expected and I have tried different versions of Nvidia drivers (295.20, 295.33, 295.40 and the latest 302.XX from xorg-edgers) The results are all the same, works in Gnome Shell but not in Unity 3d. Disabling syn to vbank works if movie is not in full screen mode, but it doesn't work for full screen. I have searched around and haven't found much info. I am wondering if others are experiencing the same problem and if there are some known work around that I have missed. Unity 3d is otherwise very nice in Precise, but this is a show stopping issue for me (literally). Thanks. I have filed a bug here https://bugs.launchpad.net/unity/+bug/993397

• Clonezilla failing as soon as image copying begins

  - by mmr

  I have been trying unsuccessfully to create an image of an Ubuntu 10.04 laptop system. As soon as the copying itself starts, the entire system crashes to a black screen. I suspect that the problem is overheating, and that's why I put an ice pack under the machine. That seems to have helped a bit, but it's still not getting through the copying process. Is there any other possible explanation for dying to a black screen like this? I'm just not relishing the task of removing the hard drive, mounting it elsewhere, and then doing a backup that way.

• Invisible boundary on Synergy client

  - by Jayson Rowe

  I have a Desktop system (named 'desktop') with 2 monitors attached (one 1680x1050 and another 1920x1080 resolution), running a synergy server. I also have a small ITX machine (named 'tiny') to my right that has a single monitor running at 1280x1024. The dual-monitor desktop is the synergy "server" and the single monitor system is the "client". Synergy works fine with one exception; if I move the mouse to the client, I can't move my mouse below the top two-thirds of the screen - it just stops. I can grab a mouse attached to the computer, and it moves all the way down, but as soon as I touch the mouse attached to the server, it jumps back to the top of the screen. Is there an issue with my config? section: screens desktop: tiny: end section: links desktop: right = tiny tiny: left = desktop end Thanks in advance for any suggestions. +----------------------------+-----------------------------+ | | | | | | | | +-----------------+ | | | | | desktop 1680x1050 | desktop 1920x1080 | | | | | | | | | tiny 1280x1024 | | | |+---------------+| | | |XXXXXXXXXXXXXXXXX| +----------------------------+-----------------------------+-----------------+

• Windows move to external monitor when closing lid

  - by Martijn

  I'm using Cinnamon (on 12.10) on a laptop (Compaq 6710b business model) with an external monitor. Both screens run at 1680 x 1050, the external monitor is located on the right. During normal operation everything works fine; windows open in whatever monitor my mouse pointer is when they open and I can freely drag them to the other monitor. When I close the lid of my laptop both displays shut down as expected. When I open the lid, however, the lock window opens on the external monitor and any windows that were open on the laptop screen have moved to the external monitor as well. Nothing happens between closing the lid and opening it; no suspend, powerdown, hibernate or anything, monitor stays attached; even mouse is untouched (pointer on laptop screen). Is there any way to fix it so my windows stay on whatever monitor I left them before closing the lid? Alternative solutions are welcome.

• Getting Wacom Bamboo Pen + Touch pressure sensitivy in GIMP

  - by Bart van Heukelom

  I've installed my Wacom Bamboo Pen + Touch (CTH-460) in Ubuntu (at least on one system, not another) and the pen works well for controlling the mouse cursor. However, I can't get pressure sensitivity to work in GIMP. I have 4 extra devices in the input devices settings screen now, two of which are the pen and eraser. I've set them both from Disabled to Screen, and left the default settings intact. However, after saving I still don't see any pressure options in the brush tool's options. I've also tried setting the mode to Window instead, but it makes no difference regarding pressure sensitivity. There are no other modes. The pressure works out-of-the-box in Blender (grease pen) so it must be something in GIMP. What can be wrong? Why don't the options appear? How can I debug this?

• building a game for different resoulution phones

  - by Jason

  Hi, I am starting some tests for building a game on the android program. So far everything is working and seems nice. However I do not understand how to make sure my game looks correct on all phones as the all will have slightly different screen ratios (and even very different on some odd phones) What I am doing right now is making a view frustrum ( could also be ortho ) which I set to go from -ratio to +ratio ( as I have seen on many examples) however this causes my test shape to be stretched and sometimes cut off by the edge of the screen. I am tilting my phone to landscape to do my tests ( a bit extreame) but it should still render correctly if I have dome things right. Should I be scaling by some ratio before drawing or something? An example would be greatly apriciated PS I am doing a 2d game

• What You Said: How You Customize Your Computer

  - by Jason Fitzpatrick

  Earlier this week we asked you to share the ways you customize your computing experience. You sounded off in the comments and we rounded up your tips and tricks to share. Read on to see how your fellow personalize their computers. It would seem the first stop on just about everyone’s customization route is stripping away the bloat/crapware. Lisa Wang writes: Depending on how much time I have when I receive my new machine,I might do the following in a few batches, starting with the simplest one. Usually, my list goes like this:1.Remove all bloatware and pretty much unneeded stuffs.2.Change my wallpaper,login screen,themes, and sound.3.Installing my ‘must-have’ softwares-starting with fences and rocketdock+stacks plugin4.Setting taskbar to autohide, pinning some apps there5.Installing additional languages6.Tweaking all settings and keyboard shortcuts to my preferance7.Changing the icons(either manual or with TuneUp Styler) Interface tweaks like the aforementioned Fences and Rocket Dock made quite a few appearances, as did Rainmeter.

• Dual Monitor/Xinerama not working; cannot even detect on-board graphic card

  - by Steven H

  I have Kubuntu 12.04 and two identical VGA monitors. One I plugged via DVI-VGA adapter into the DVI port of my discrete AMD Radeon HD 6670, the other into the VGA port of my on-board graphic card (Radeon HD 6410D). After installing Kubuntu I got a black screen, so I booted with nomodeset and installed AMD's catalyst drivers but only the monitor plugged into the discrete graphic card worked. Using lspci I saw that the on-board graphics was not listed. Then I found in the BIOS settings the options "Surround View" and "Onboard Dual Link DVI" both disabled. After enabling both, the on-board graphics card shows up in lspci but in amdcccle, it only shows as [Uknown display]Uknown adapter. When I try to enable xinerama, I get a black screen after rebooting on both monitors. I tried several options and hints from the web but nothing worked so far. I also reinstalled the AMD drivers several times. What should I do?

• how to add water effect to an image

  - by brainydexter

  This is what I am trying to achieve: A given image would occupy say 3/4th height of the screen. The remaining 1/4th area would be a reflection of it with some waves (water effect) on it. I'm not sure how to do this. But here's my approach: render the given texture to another texture called mirror texture (maybe FBOs can help me?) invert mirror texture (scale it by -1 along Y) render mirror texture at height = 3/4 of the screen add some sense of noise to it OR using pixel shader and time, put pixel.z = sin(time) to make it wavy (Tech: C++/OpenGL/glsl) Is my approach correct ? Is there a better way to do this ? Also, can someone please recommend me if using FrameBuffer Objects would be the right thing here ? Thanks

• Why doesn't my graphic card software support 1280*1024?

  - by Allwar

  Hi, I have an external monitor which is an 20" 1280*1024. In windows 7 it works fine with that resolution but in ubuntu it can't. Example: In windows I connect it and activates it, done. In ubuntu I connect and the only resolution that is available is the ones my laptop screen support, 12" 1366*768. My laptop is an asus 1201n. If I force it to use 1280*1024 both screen crashes and i have to force a reboot. When I force it I only force the external monitor, the laptop is already at maximum 1366*768. I connect it throw VGA.

• Q-Tec Webcam 100 (093a:2460) video quality is horrible at best

  - by Sir Emeth

  I just bought a new usb webcam for my desktop setup of Ubuntu Natty Narwhal. I plugged it in, started up Cheese, and saw my smiling face. But it was green and lined, very poor quality overall. I am skeptical that this is due to a poor quality webcam. :P I tried it in Skype, Google+, and Gchat, but all of those showed only a black screen. They recognized the webcam as present, but showed no stream from it. Kamoso showed a black screen as well, and Camorama had even poorer quality than Cheese. Here are the details for the webcam from lsusb: Bus 001 Device 005: ID 093a:2460 Pixart Imaging, Inc. Q-TEC WEBCAM 100 Am I missing a driver, or are there settings somewhere I need to tweak?

• Design virtual resolution for 2D development in Unity

  - by djzmo

  I came to Unity with Cocos2D experience in mind. In Cocos2D, I can choose a "virtual" screen resolution size to rely on the entire game during development and the game will automatically adapt to different screen sizes in various devices. Now that I'm migrating to Unity and has access to 4.3 beta which has a native 2D workflow, is there a similar mechanism that will automate this? After playing around a bit with Unity, I also found out that Unity uses a neutral coordinate unit that can translate to pixels flexibly (CMIIW). But when developing a 2D game, I need them in pixels. Thank you.

• How can a computer render a CLI/console along with a GUI?

  - by Nathaniel Bennett

  I'm confused when looking into graphics - specifically with operating systems. I mean, how can a computer render a CLI/console along with a GUI? GUI's are completely different from text. And how can we have GUI windows that display text interfaces, ie how can we have CLI in modern Graphics Operating system - that's what I'm mainly trying to grip on to. How does graphics get rendered to display? Is there some sort of memory address that a GPU access which holds all pixel data, and there system's within OS's that gather the pixel position of windows and widgets, along with the Z Index and rasterize them to that memory address, which then the GPU loads to the screen? How about the CLI's integrated with Graphics? How does the OS tell the GPU that a certain part of the screen wants to display text while the rest wants to display pixel data?

• 12.10 does not boot sometimes from the hard drive, but it does consistently from the CD

  - by Robert

  I have recently switched from Windows 7 to Ubuntu 12.10. I have installed Ubuntu 12.10 and I cleared everything from my computer, but it randomly stops at different screens. Only a purple screen comes up. I can choose Ubuntu from a list and a blinking white dot appears in the top left corner. The previous things happen and the Ubuntu login screen appears an I can log in. It is random. and I have not changed anything. I can always insert the bootable CD and it will work every time.

• How to workaround or diagnose a kernel panic when "safely removing" external hdd?

  - by Shawn

  I'm experiencing an issue when using the "Safely Remove" option to remove my 1TB external HDD from the Unity Launcher. Not every time, but occasionally my screen will go black and display LARGE amounts of text information (which I obviously cannot screen cap). The jist of the info displayed is that unmounting or 'safely removing' the drive causes a kernel panic. Is there a Command Line command to remove mounted drives, or at least one that would show me some sort of error output when the drive is removed? I'm trying to narrow down the cause. I could be imagining this, but it seems to happen most often when I have other programs running when I remove the drive (i.e. Firefox, Transmission). Please note that my external drive is not in use when I attempt to remove it and it is not being used either by Firefox or Transmission at these times. Any help would be appreciated.

• Making a Background Scrolling in Stacking Game

  - by David Dimalanta

  Hmmm...Is it a good idea to use a LibGDX parallax background for making a stacking game (i.e. PAPA STACKer Lite)? For example, I'm starting to use the blocks to drag-n-drop it. Next, when the next piece reaches the top of the screen, it automatically scrolls to the next one where the available space left. Aside from that, is it also involved with the camera code (Orthographic Camera) that the screen size appeared like 720x1280 but actually it's 1440x2560 for example? And another thing, does the background scrolling have the option to scroll from start to finish and infinite?

• My computer will no longer suspend or shut off when I close the lid

  This is somewhat annoying. I have an old laptop and the screen on it is shot, so now I have an old monitor hooked up and it works fine. Before the upgrade I had it set so that when i closed the lid on the laptop everything would shutdown or suspend, when I lift the lid, everything would come back. Now, however, when i close the lid nothing happens, when i open the lid the screen flashes black and comes back. I have it set so that it should suspend when i close the lid. It's confusing...

When i open Ubuntu after reboot, there is absolutely nothing on the desktop screen except for an 'Untitled' folder at the corner of the screen. There is no menu, no taskbars at the top whatever. I dont know why this is happening. The .iso from which i have booted amd installed Ubuntu is fine. I have already conducted an md5sum test and it was all fine. Looking forward to your response.
