• Graphics system failure

  - by anonymous coward

  I just upgraded two versions of Ubuntu to Oneiric after a recent set of updates broke Audacious 2.4.something in Maverick for me. When it was all finished my Asus Eee 1215N with the 1366x768 screen and the notoriously unsupported Nvidia Ion2 Optimus chipset was working on minimum compatibility fallbacks at 1024x768 resolution. So I did a little bit of reading (not enough) and tried deleting a couple parts of the graphics system to see if I could force a retry on the autodetection. The result: No graphical shell works now. Attempted so far: -reinstalling xorg/nouveau, didn't work. -installing bumblebee/nvidia-current, didn't work. -sudo dpkg-reconfigure -phigh -a, didn't work. I'd like to stress that this is otherwise a perfectly functional installation that I had spent some time setting up already (including a successful compile of Audacious 3.21 that was working with all the plugins). Is there a way for me to rebuild the graphics system from scratch or should I just give up, cry a little, backup data, wipe partition and reinstall with a USB drive?

• 12.10 Booting Into Variations Of Blank Screen

  - by user93954

  I've been running the Ubuntu 12.10 beta since about a month before the final release with almost no problems. However since the day of release (I'm assuming an update has caused this) I have had problems booting into the actual GUI interface. Trying to get it to work is just a case of hard shutting down until it works, but for most of the time I need to battle with various different kinds of black screens. These include a plain black screen, a flashing line and a flashing line that doesn't fit the resolution. Nine times out of ten the cursor will be displayed over these. It also sometimes manages to boot into Ubuntu, albeit text mode or sometimes it loads GRUB which it isn't setup to do. If anyone could help out with this it'd be great. I really, really don't want to have to go through yet another clean installation. Cheers.

• How can I use my laptop's monitor as my PC's ONLY monitor? [closed]

  - by Randell

  Possible Duplicate: Can I use my laptop as a second monitor for my desk computer? My PC's monitor just died and I'm not looking at buying a new monitor anytime soon. So I'm thinking of using my laptop's monitor for it. Both machines are running on Fedora linux. Edit: Both machines are connected to the same wireless network. PC needs to log in before it can connect to the network if I'm not mistaken. Update: This is different from Can I use my laptop as a second monitor for my desk computer? , because that question is asking how to use the laptop screen as the secondary display, not as the only display.

• Fujitsu Siemens V6535 laptop doesn't wake up - crash when going into standby?

  - by marc

  I'm having trouble with my laptop (Fujitsu Siemens model V6535). It runs Windows 7, and after I upgraded from Vista I've noticed something that makes me really angry. When my laptop goes into Standby, the power LED changes to red and starts blinking (standby mode). When I push the power button to wake it up it, the blinking LED changes to green but nothing else happens. Nothing on the display, no HDD sound. When I press the power button for a few seconds and then try turn it on again, it doesn't display anything. I have to unplug the charger, shut it off, and power it on again without the power cable. Then it starts working. A few days ago I upgraded the BIOS to the newest version, but it doesn't help. Does anyone have any idea what can be wrong?

• Cannot access an application folder in Program files

  - by GiddyUpHorsey

  I recently installed Windows 7 Professional 64bit on a new machine. I installed an application using a ClickOnce installer. The application runs fine, but I cannot access the application folder it created in c:\Program files (x86). It bombs with access denied. I try to view the properties on the folder and it takes about 1 minute to display (other folders take 1 second). It says I cannot view any information because I'm not the owner. It doesn't say who the current owner is (instead - Unable to display current owner.) but says I can take ownership. When I try it fails again with Access Denied, even though I have administrative permissions. Why can't I access this folder nor take ownership?

• OM: Effective Troubleshooting Techniques to Debug Order Import

  - by ChristineS

  There is a new document available to help you debug Order Import in Order Management:  Effective Troubleshooting Techniques to Debug Order Import Issues (Doc ID 1558196.1) The white paper addresses debugging from a technical perspective. This approach is to assist users in understanding the actual issue, as well as help them in the early resolution of any order import issue. It will walk you through several cases, with supporting debug logs / trace files taken for each case. Educating you along the way for what debug logs / trace files should be gathered, as trace files are not always needed.  It will also walk you through the supporting documents so you will know what to look for in your case. Please refer to this note the next time you have an Order Import error. Or you could step through it now, so you are informed the next time you encounter an Order Import error.  Happy debugging!

• SFML - Moving a sprite on mouseclick

  - by Mike

  I want to be able to move a sprite from a current location to another based upon where the user clicks in the window. This is the code that I have: #include <SFML/Graphics.hpp> int main() { // Create the main window sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window"); // Load a sprite to display sf::Texture Image; if (!Image.LoadFromFile("cb.bmp")) return EXIT_FAILURE; sf::Sprite Sprite(Image); // Define the spead of the sprite float spriteSpeed = 200.f; // Start the game loop while (App.IsOpened()) { if (sf::Keyboard::IsKeyPressed(sf::Keyboard::Escape)) App.Close(); if (sf::Mouse::IsButtonPressed(sf::Mouse::Right)) { Sprite.SetPosition(sf::Mouse::GetPosition(App).x, sf::Mouse::GetPosition(App).y); } // Clear screen App.Clear(); // Draw the sprite App.Draw(Sprite); // Update the window App.Display(); } return EXIT_SUCCESS; } But instead of just setting the position I want to use Sprite.Move() and gradually move the sprite from one position to another. The question is how? Later I plan on adding a node system into each map so I can use Dijkstra's algorithm, but I'll still need this for moving between nodes.

• Asus Eee PC 701 4G hangs on boot

  - by Andrew

  I've got an old Eee PC 701 4G with the following specifications: 512 MB RAM 4GB SSD drive SM223AC 8GB SD card extension Screen resolution: 800 x 480 BIOS Revision 1101 (05/16/2008) EC Firmware version: EPC-079 Windows XP SP3 works fine on it, but I decided to switch my OS to Ubuntu. I have downloaded an Ubuntu 10.10 Netbook Remix ISO and wrote it to my FAT32 SD card using Universal-USB-Installer-1.8.3.3, as described on ubuntu.com During standard load from the SD card the boot process hangs up with black screen. If I'll press F6 while preloading Ubuntu, it sucessfully displays the boot menu, selecting language and showing 2 main commands: "Run ubuntu from USB drive" and "Install Ubuntu". Selecting either of these commands leading to the same result - after some background work the main loading indicator is displayed ("Ubuntu" text with dotted progress bar under it), and it's progressing forever without any effect. Is Ubuntu 10.10 compatible with my Eee PC at all? How to boot it correctly?

• Narrow-phase collision detection algorithms

  - by Marian Ivanov

  There are three phases of collision detection. Broadphase: It loops between all objecs that can interact, false positives are allowed, if it would speed up the loop. Narrowphase: Determines whether they collide, and sometimes, how, no false positives Resolution: Resolves the collision. The question I'm asking is about the narrowphase. There are multiple algorithms, differing in complexity and accuracy. Hitbox intersection: This is an a-posteriori algorithm, that has the lowest complexity, but also isn't too accurate, Color intersection: Hitbox intersection for each pixel, a-posteriori, pixel-perfect, not accuratee in regards to time, higher complexity Separating axis theorem: This is used more often, accurate for triangles, however, a-posteriori, as it can't find the edge, when taking last frame in account, it's more stable Linear raycasting: A-priori algorithm, useful for semi-realistic-looking physics, finds the intersection point, even more accurate than SAT, but with more complexity Spline interpolation: A-priori, even more accurate than linear rays, even more coplexity. There are probably many more that I've forgot about. The question is, in when is it better to use SAT, when rays, when splines, and whether there is anything better.

• My card reader doesn't show up at all, but previously did in 10.10

  - by Nathan J. Brauer

  I bought a pin-based-USB powered internal media card reader and it worked perfectly when I first installed Ubuntu 10.10 a month ago. I used it a few times since and today I booted up the computer and it's not working. Here's how it used to work: In nautilus->computer, 5 "drives" would display even when no card was inserted. One for each slot (SD, XD, CF/MS, etc). Opening one w/o a card would initiate a "Please insert card." dialog. Inserting a card would automatically open nautilus. Now: No drives display at all whether cards are inserted or not. lsusb lists the following (which seems to indicate that it's not being detected) Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 002: ID 046d:c52e Logitech, Inc. (my keyboard/mouse) Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub (A side note, all of my USB ports are 2.0 + 1 USB port which is 3.0, why does everything say 1.1/2.0?) I tried using ubuntu-bug but for USB devices it expects you to be able to remove and insert them while the computer is running -- obviously something you probably shouldn't be doing when you're dealing with devices plugged straight into the USB pins. Thanks in advance!

• Joining Two MKV files in Ubuntu?

  - by Ryan McClure

  I have an opera that I'm ripping to my computer in MKV format with Handbrake. This opera is on two discs. Is there a way to join the resulting MKV's together? They will have the same bitrate, resolution, etc. If I do this, can I keep chapters from both MKV files organized? And, since I have subtitles in the file (not burnt in), will they still stay intact? I'm not too sure if this question is off-topic or not. If it is, feel more than free to delete it. :)

• Lost the config of my monitor once I connected it to a KVM switch.

  - by jfmessier

  I used to have a monitor (Acer 20", AL2017) connected to the external video port of my laptop. Everything was great and I could get a rather high resolution available when setting it under Ubuntu (all versions). But since I connected it to a KVM, the monitor is no more recognized, and I cannot go beyond 1024x768. My video adapter is an Intel chipset 9xx from an older Pentium Core 2 Duo laptop. The same monitor, using another video chipset (Intel 82G33/G31 rev 02) is properly detected through the switch box. Looks to me like the video chipset is not the best, and I can live with this. I see that I have no xorg.conf, and I understand that I would need to generate one so I can then use it to force the available modes on the X system. How can I generate the xorg.conf file for my Intel video chip, so I can use it then ? Merci :-)

• Virtual screen size with libgdx and GLES 2

  - by David Saltares Márquez

  I've been trying to use a virtual screen size for my libgdx desktop-android game. I'd like to always use a 16:9 aspect ratio but with a virtual screen size so everything would adapt automatically depending on the device size. This post illustrates the process pretty well but my game crashes when camera.apply(Gdx.Gl10) is called. This is because I'm using GLES 2.0 (for not having to use multiple of 2 texture sizes). As stated in the OrthographicCamera doc, the apply method only works with GLES 1 and GLES 1.1. Is there another way of applying my GL transformation to the camera so I can use a virtual screen resolution? Having to resize everything manually it's a total pain. Thanks a lot.

• Excel removing leading leading zeros when displaying CSV data

  - by Velika Kudac

  I have a CSV text file with the following content: "Col1","Col2" "01",A "2",B "10", C When I open it up with Excel, it displays as shown here: Note that Cell 2A attempts to display "01" as a number without a leading 0. When I format rows 2 through 4 as "Text", it changes the display to ...but still the leading "0" is gone. Is there a way to open up a CSV file in XLS and be able to see all of the leading zeros in the file by flipping some option? I do not want to have to retype '01 in every cell that should have a leading zero. Furthermore, using a leading apostrophe necessitates that the changes be saved to a XLS format when CSV is desired. My goal is simply to use Excel to view the actual content of the file as text without Excel trying to do me any formatting favors.

• Cannot restart Ubuntu after replacing Unity with Gnome and purging lightdm

  - by OtagoHarbour

  I am running Ubuntu 11.10. I used the directions here to replace Unity with Gnome. It seemed to work fine until the end of step 2 when I rebooted the computer. When I chose the default option, I just got a black screen. When I choose the restore option and then "Restore normal boot" I get Starting load fallback graphics devices [fail] Starting GNOME Display Manager [ok] Starting Userspace bootsplash [ok] Stopping GNOME Display Manager [ok] Stopping Userspace bootsplash [ok] Starting web server apach22 [fail] (among a lot of OKs) It finally gets to Stopping System V runlevel compatibility [ok] where it hangs. I left it overnight and just had a blank screen when I checked it in the morning. I can "Drop to root shell prompt" and "Drop to root shell prompt with networking". I did see here that one should be able to fix the problem by choosing remount and then doing apt-get install lightdm I tried this as root shell with and without networking and got the message Err http://us.archive.ubuntu.com/ubuntu/ oneric-updates/main lightdm i386 1.0.6-0ubuntu1.7 Could not resolve 'us.archive.ubuntu.com/ubuntu' What is the best way to resolve this problem? Thanks, Peter.

• CRT as 2nd monitor goes screwy after start up?

  - by rhys

  new install of 12.04 on an old dell with a radeon ATI RV516 video card with monitor out and s-video out. During boot up all is good. Both screens operate and look fine. Then just before the desktop appears the cCRT goes purple and is covered in heavy horizontal lines, but as i said during boot up it was fine and the resolution was fine. The main monitor, an lcd, operates normally. everything else works fine, it's just the picture on the CRT that is screwed up. I used the same monitor and CRT running 11.10 which worked fine any help would be appreciated and yes i am a newbie to ubuntu here is a vid showing the completely normal screens at reboot then the purple badness when the desktop loads ?? and don't laugh at the slow machine, it's old. http://www.youtube.com/my_videos_edit?ns=1&video_id=zfuh6lBMLnc

• Why Does My iMac Keep Setting the Screen Brightness to 'Full'?

  - by TomB

  I have a 2 week old 24" iMac running Mac OS X 10.6. It is the primary monitor with the menu bar on the top of display. I have an external monitor as well, a 19" Viewsonic LCD. The LCD is set to the left side of the iMac, rotated 90 degrees CCW and has the Dock along the far left edge. When I restart the screen brightness on the iMac reverts to Full brightness. The Viewsonic LCD retains the setting I have for it. I am using a Mini DVI to DVI cable for the external display. I even tried setting my Huey Pro to do automatic screen adjustment based on ambient lighting but the iMac still goes to stun with a reboot. I am sure it is something dumb I have overlooked.

• nomachine NX: Text missing on all gtk interface (Unity and Gnome Classic)

  - by hansioux

  [Edit] I later realized my issue only occurs when I am using NX to remote access my machine. Therefore I edited the title and description. I have also found the temp solution, which is to "disable render extension" in the custom display settings. But doing so makes the NX experience very slow laggy, and not that nice to look at. [/EDIT] I did a fresh install on a new computer, and was trying to setup my fonts. When I log in remotely via NX, my the text are missing on all gtk based interfaces. That means most menues (except for unity), right click menues, applications themselves, terminal, and so on. About the only thing unaffected is firefox. all the texts are showing just fine for firefox. So that probably already says something about text permissions. I went to check if my fonts have the correct permissions and they do. I removed my custom settings from /etc/fonts/config.d, and still the texts are missing. There is a work around by using "disable render extension" in the custom display settings. How do I fix this issue permanently?

• WP7&ndash;Samsung Owners Should Hold Off on the Update

  - by D'Arcy Lussier

  Microsoft released an update for WP7 that’s meant to improve updating the devices going forward. They’ve identified a glitch though, specifically with Samsung phones. From Winrumors: A number of Windows Phone 7 users applied the patch on Monday and some Samsung Omnia owners devices have been left in a “bricked” state. Devices simply instruct users to connect them to a PC, hard resetting the device or connecting it to a PC does not appear to solve the issue. Microsoft has also been advising users with broken devices to return them to stores for exchange. The scary thing about this is the resolution: return the “broken” devices to stores for exchange. Many Samsung Focus owners in Canada purchased unlocked phones from the US, and supposedly that act alone voided the warranty. So applying the update has very dire implications for those who might be left with a very pretty brick. I’m going to wait until there are successful installs of the patched update before going ahead with it on my device.
