• Stop Windows boot

  - by Parley Applegate

  Installed Ubuntu over a Windows8 trial. After installation, Windows8 still tries to boot. Wiped disk clean with Acronis and reinstall Ubuntu. Windows8 still tries to start, but goes to blank screen. Ubuntu never tries to boot. Naturally live mode works fine. What do you think of wiping disk again, install Windows7 and try using GRUB approach or do you know how to remove Windows from the cleaned disk?

• When will fglrx work on latest Xorg server 1.9?

  - by user9032

  As many laptops with an ATI Radeon (5470HD) in it, mine is having issues too when installing the proprietary driver fglrx (screen hangs on startup). I read somewhere that these issues appear because the latest fglrx driver doesn't support the latest Xorg server 1.9 yet, which is installed on Ubuntu 10.10. So my question is whether any of you know when ati will support the latest xorg server? Thanks in advance!

• LWJGL: Camera distance from image plane?

  - by Rogem

  Let me paste some code before I ask the question... public static void createWindow(int[] args) { try { Display.setFullscreen(false); DisplayMode d[] = Display.getAvailableDisplayModes(); for (int i = 0; i < d.length; i++) { if (d[i].getWidth() == args[0] && d[i].getHeight() == args[1] && d[i].getBitsPerPixel() == 32) { displayMode = d[i]; break; } } Display.setDisplayMode(displayMode); Display.create(); } catch (Exception e) { e.printStackTrace(); System.exit(0); } } public static void initGL() { GL11.glEnable(GL11.GL_TEXTURE_2D); GL11.glShadeModel(GL11.GL_SMOOTH); GL11.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); GL11.glClearDepth(1.0); GL11.glEnable(GL11.GL_DEPTH_TEST); GL11.glDepthFunc(GL11.GL_LEQUAL); GL11.glMatrixMode(GL11.GL_PROJECTION); GL11.glLoadIdentity(); GLU.gluPerspective(45.0f, (float) displayMode.getWidth() / (float) displayMode.getHeight(), 0.1f, 100.0f); GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glHint(GL11.GL_PERSPECTIVE_CORRECTION_HINT, GL11.GL_NICEST); } So, with the camera and screen setup out of the way, I can now ask the actual question: How do I know what the camera distance is from the image plane? I also would like to know what the angle between the image plane's center normal and a line drawn from the middle of one of the edges to the camera position is. This will be used to consequently draw a vector from the camera's position through the player's click-coordinates to determine the world coordinates they clicked (or could've clicked). Also, when I set the camera coordinates, do I set the coordinates of the camera or do I set the coordinates of the image plane? Thank you for your help. EDIT: So, I managed to solve how to calculate the distance of the camera... Here's the relevant code... private static float getScreenFOV(int dim) { if (dim == 0) { float dist = (float) Math.tan((Math.PI / 2 - Math.toRadians(FOV_Y))/2) * 0.5f; float FOV_X = 2 * (float) Math.atan(getScreenRatio() * 0.5f / dist); return FOV_X; } else if (dim == 1) { return FOV_Y; } return 0; } FOV_Y is the Field of View that one defines in gluPerspective (float fovy in javadoc). This seems to be (and would logically be) for the height of the screen. Now I just need to figure out how to calculate that vector.

• Boot menu doesn't show up

  - by Zloboo

  I found some topics about dualbooting, but nothing was exactly what I need, so: I have Win7 and I installed Ubuntu 12.04 LTS from a flash drive. Everything went smoothly and I was given the "for installation to finish, need to reboot" screen. I removed the flash drive, the PC restarted. I was expecting to be greeted with the menu where I choose the OS I want to launch, but instead the Windows happily starts.

• Can I move the unity launcher in 12.10? [closed]

  - by Linds

  Possible Duplicate: Can I move the Unity launcher? I've just recently downloaded ubuntu 12.10, and just like everyone else using the Unity Launcher I would like to move it to the bottom of the screen. I know there are patches for 11.10, and I think for 12.04, but I haven't been able to find anything to solve this problem on 12.10. Is there a way, or is everyone else with 12.10 waiting for a solution as well?

• How to use tscon on Windows7?

  - by Radek

  I need to run overnight automation testing using RFT and IE on Windows7 virtual machine. I found that restarting the Windows box before the testing starts helps. I am moving the production environment from Windows XP to Windows 7. RFT used to complain when running RFT scripts that CRFCN0557E: Activation failed when running under a Terminal Services environment. This may be caused by using a minimized terminal window - try playing back without minimizing the terminal window (it does not need to be full-screen). Running tscon.exe 0 /dest:console prior starting any RFT script fix the error on Windows XP. But not on Windows7. I did some research and was trying for hours to fix that but nothing helped. There is no screen saver turned on on Windows7. I tried to run both but nothing helped. tscon.exe 0 /dest:console tscon.exe 1 /dest:console On Windows7 tscon returns {ErrorPrintf(): LoadString failed, Error 15105, (0x00003B01)} Error [15105]:The resource loader cache doesn't have loaded MUI entry. Error [0]:The operation completed successfully. On Windows XP tscon returns Could not connect sessionID 0 to sessionname console, Error code 7045 Error [7045]:The requested session access is denied. I just double checked that running tscon.exe 0 /dest:console on Windows XP solves the issue. Cannot understand the output of the tscon command then. Any idea how I can run RFT scripts after I restart the Windows box automatically? Preferably without involving any other computer. I was even thinking to use the old Windows XP to make remote desktop session to make RFT happy. I hope there is other better solution to that.

• Install McAfee ePO Agent via Group Policy

  - by neildeadman

  We have recently deployed ePO to our infrastructure, but the Agent will not deploy to all systems. We suspect this is a firewall issue as disabing Windows Firewall generally makes it work. We have decided to install the Agent via Group Policy to make sure all systems get the it and then ePO will deploy VirusScan on reboot. Following the manual I have run: Framepkg.exe /gengpomsi /SiteInfo=<sharedpath>\SiteList.xml /FrmInstLogLoc=<localtempDir> \<filename>.log and then created the GPO, but it never installs. Has anyone managed to get this working? Or maybe they can suggest a resolution for the failed installs of Agent deploy from ePO?

• MSTSC crash on connect

  - by rotard

  We are supporting a client with primarily Windows XP machines. The users need to use Remote Desktop to connect to a terminal server. Unfortunately, after upgrading to SP3 on some machines MSTSC.exe crashes when they try to connect to the terminal server (a Win 2008 machine). The resolution I have found has been to revert to an older version of MSTSC as described here: http://it.tmod.pl/Blog/EntryId/115/Remote-Desktop-Connection-crashes.aspx . Another tech at my company independently arrived at a similar solution. Unfortunately, now some of the user's printers are missing (when connected tot he terminal server). Has anyone else seen this issue? How did you resolve it?

• PDF Converter wanted: Convert 8.5*11 PDF images into 600*800px PDF images for the Nook

  - by Astro

  I have PDF files that are maritime charts, For example this one from the Delaware Bay http://ocsdata.ncd.noaa.gov/BookletChart/12304_BookletChart_HomeEd.pdf There is a lot of detailed information in the image. When I show them on a monitor the details are shown. When I put them on the Nook they are sized to fit the Nook screen (about 3*5) and all the details are lost. Since the Nook pdf reader does not have a zoom feature, the charts are unreadable. I'd like to convert them to fit on the Nook screen(600*800px). This means the images would need to be sliced into multiple images. (ie a single image (page) would get split into 5 rows and 4 columns) In a perfect world they would get converted with a slight overlap, left to right, top to bottom. I could then page through the smaller slices to find the section I need. I had used PaperCrop in the past to convert two col PDF's (highly recommended) but it can't do anything with the images. ImageMagick does a lot with combining images, but I didn't see any split options to split the image into tiles. Windows program preferred. Thanks!

• Can I use a 27" iMac as a additional monitor for another 27" iMac?

  - by Darren Newton

  I currently have a 27" iMac i7 with the 512mb ATI card. After looking at prices on other Apple displays it appears I can purchase another low-end 27" iMac (Core 2 Duo basic model) for less than a 30" display. 3 Part question: Can I easily use the lower-end iMac as an additional monitor to my higher end iMac? While I am using the lower-end iMac as an additional monitor can I still take advantage of its CPU to do things like run a webserver, compress video with Handbrake, etc? Are there any other 27" LCD displays with the same resolution (2560 x 1440) cheaper than the basic iMac (~$1699.00 US)? Any insights appreciated.

• Using a GoDaddy SSL certificate with Virtualmin (Webmin)

• No VMKernel Dump File on PSOD for ESXi 4

• Problem booting virtual machine after converting VMDK to VHD

  - by vg1890

  I used the VMWare VCenter Converter Standalone Client to convert a physical drive on my old PC to a virtual drive. The conversion worked fine and I ended up with a valid VMDK file. Next, I wanted to convert the VMDK to a VHD for use with Microsoft Virtual PC, since that's what I use on my new box. I used WinImage for the conversion and that worked fine, too. I can access the files from the virtual drive through WinImage. However, when I create a new virtual machine using Virtual PC and add the existing VHD file, the machine doesn't boot. The initial boot screen flashes with the amount of RAM and then the screen goes black. If I turn off the VM and reboot in safe mode I can see the drivers being loaded until eventually it gets to crcdisk.sys and hangs indefinitely. Any ideas how to fix this? I'm not opposed to starting over from scratch if there's another method to turn my physical machine into a Virtual PC VM. Thanks! EDIT - I should add that the virtual drive is a system boot drive and not a secondary drive. EDIT - I tried booting from the install CD and doing a repair. The result was that the system could not be repaired due to a "driver error."
