• Hiding monitor from windows, working with it from my app only [closed]

  - by Mikhail

  I need to use a monitor as a "private" device for my special application, I want to use it as a flashlight of a sort and draw special patterns on it in full screen. I don't want this monitor to be recognized by OS (Windows 7) as a monitor. I.e. user should not be able to move mouse to that monitor, or change its resolution, or run screensaver on it or whatever. But I want to be able to interact with it from my application. Monitor is plugged using an HDMI cable to a video card (most probably nVidia). What is the simplest way to do this? All solutions are appreciated, including purchasing additional adapters or simple video cards, or any other special devices.

• Ubuntu stops using Nvidia driver after kernel upgrade

  - by Daniel

  Just updated and restarted, Ubuntu's doesn't display correctly. After restart, the desktop now looks like this. I've temporarily switched to the Nouveau driver. The update history reveals the kernel was updated, amongst many things; and the following were installed: linux-image-3.5.0-19-generic (3.5.0-19.30) linux-image-extra-3.5.0-19-generic (3.5.0-19.30) I've encountered this type of problem quite recently, so I decided to reapply the same steps, to solve the problem, as follows: sudo apt-get install linux-headers-3.5.0-19 sudo apt-get install linux-headers-3.5.0-19-generic sudo depmod -a sudo modprobe nvidia sudo /etc/init.d/*dm restart When installing linux-headers-3.5.0-19-generic, I get an error, message from terminal as follows: Setting up linux-headers-3.5.0-19-generic (3.5.0-19.30) ... Examining /etc/kernel/header_postinst.d. run-parts: executing /etc/kernel/header_postinst.d/dkms 3.5.0-19-generic /boot/vmlinuz-3.5.0-19-generic Error! Problems with depmod detected. Automatically uninstalling this module. DKMS: Install Failed (depmod problems). Module rolled back to built state. However, I ignored the above error and continued the steps with sudo depmod -a, installed nvidia-current, then did sudo modprobe nvidia, which yielded the following error: FATAL: Error inserting nvidia_current (/lib/modules/3.5.0-19-generic/updates/dkms/nvidia_current.ko): No such device Upon restart, the Nvidia driver now works! BTW, do those error messages imply I broke something? Just curious, cause I don't want to get happy I've fixed it, then it stops working later on. The system is Dell XPS-L702X, with NVIDIA GeForce GT 555M, and 17" screen.

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• Install GRUB to Ubuntu Partition

  - by Noel

  So my computer has the following partitions: /dev/sda -- (I know this isn't a real partition, but more so the boot loader) /dev/sda1 -- (Windows 7 Boot Loader) /dev/sda3 -- (Windows 7) /dev/sda4 -- (Data partition, NTFS) that means i have /dev/sda2 as free space. I do not want to change the MBR of the computer. I would like /dev/sda2 to contain GRUB AND Ubuntu. So ideally when I turn my computer on, BIOS would ask if I'd like to boot Windows 7 or Ubuntu(or Grub or partition 2), and I could choose either one. But I would like Grub and Ubuntu to be on the same partition, so they will not interfere in any way with windows or window's boot loader/partition (sda3) How can I do this? Catch: when formatting partitions, Ubuntu does not give me the option to make them virtual partitions, so that makes things harder. I tried: installing Ubuntu to /dev/sda2 (which I formatted as ext4) and then told the Ubuntu installer to install the bootloader to /dev/sda2. But when I select "Ubuntu" from BIOS's boot selection, it loads a black screen and says "invalid arch independent ELF magic grub rescue _" and allows me to input stuff. How can I fix this, or tell my computer where Grub is?

• Convert video files for Maemo (Nokia N900) using ffmpeg/mencoder

  - by Vikrant Chaudhary

  I'm a newbie in video encoding so I'm looking for some expert advice. I'm looking to transcode media files with ffmpeg or mencoder (or something other) on Ubuntu for my Nokia N900 running Maemo. I'd prefer mencoder, because of ffmpeg's crazy dependencies. Video output should be AVC/H.264 (probably hardware accelerated on device). Audio output in AAC (should have preferred Vorbis but not supported natively and requires .mkv which is also not completely supported). Output video should retain the original aspect ratio. Resolution of screen is 800x480 (16:10). (Explanation of why-this-value-is-chosen would be really appreciated). Thanks.

• Hybrid Graphics Functional won't work with my Asus UL30V anymore

  - by futuress

  The problem is that I am no longer able to boot in compatibility mode for just turning on my Nvidia graphics to install the driver. Because no login screen will appear if Ubuntu is loading. In Ubuntu 11.10 I was able to activate nvidia graphics only' option this way: 1) Change BIOS to 'compatibility mode' which will turn off the Intel card. 2) Install the Nvidia proprietary driver using Ubuntu's driver finder (Additional Drivers) and then reboot. I was not interested using only the Intel graphics, for the sake of battery life. Now I have both cards running and they drain my battery life dramatically. And the main problem of this configuration no OpenGL is available, so I can't play any games any more. At this point, I have a pre-solution. I uninstalled the nvidia drivers and installed bumblebee. Now the Intel card is recognized. I would prefer to run just the nvidia card as in Ubuntu 11.10 but for now this is better than nothing. Does anybody else have the same problem?

• vim: how do I keep 10 lines visible when scrolling up to EOF with CRTL-F ???

  - by Gaston

  Hello! I am used to use vi, not vim. What I find annoying in vim is that when you are scrolling with CTRL-F and reach EOF, vim scrolls down to the very last line and put this line on the top of your screen, and you can't see the lines above. You must scroll up a little bit so you can see the context. All this happens with CTRL-F only, not with j or the down cursor key. In vi, you scroll down (with CTRL-F), but when you reach EOF it still show you, say, 15 lines and then the tippical ~. I am using Putty for remote access. How can I config vim to behave like vi in this case? Hope you understand the question. Thank you! Gaston.

• PeopleSoft 8.52 iPad Certification

  - by Dave Bain

  One of the real gems in the PeopleTools 8.52 release is the certification of PeopleSoft applications running in the Safari Browser on an iPad.  It is nice that PeopleSoft is not constrained by technology like Adobe Flex/Flash, so announcements like this "Adobe drops plans for mobile Flash support" do not limit our mobile solution to custom mobile development. There are parts of PeopleSoft applications that operate better on iPads than others.  One of the best is Workcenters.  Workcenters were new to PeopleTools 8.51 and we are starting to see more and more adoption of them.  Workcenters are roll based landing pages that eliminate difficult navigation by providing access to most links, pages, and reports a user in a role needs.  One of the nicest I’ve seen is the Supply Manager Workspace.  Here are some links to screenshots of what a WorkCenter looks like on an iPad: Here's the standard PeopleSoft Login Page The Supply Manager Workspace looks great full screen on an iPad iPad has a great user interface to zoom, here's a screenshot of an upclose view of an analytic. Touch one of the analytics and it drills into the details. Go ahead and give it a try.  WorkCenters and Dashboards are starting to show up across applications.  For a quick one to try, navigate to the PeopleTools->Integration Broker->Integration Network WorkCenter.  It’s new in PeopleTools 8.52.

• Zoom Layer centered on a Sprite

  - by clops

  I am in process of developing a small game where a space-ship travels through a layer (doh!), in some situations the spaceship comes close to an enemy space ship, and the whole layer is zoomed in on the two with the zoom level being dependent on the distance between the ship and the enemy. All of this works fine. The main question, however, is how do I keep the zoom being centered on the center point between the two space-ships and make sure that the two are not off-screen? Currently I control the zooming in the GameLayer object through the update method, here is the code (there is no layer repositioning here yet): -(void) prepareLayerZoomBetweenSpaceship{ CGPoint mainSpaceShipPosition = [mainSpaceShip position]; CGPoint enemySpaceShipPosition = [enemySpaceShip position]; float distance = powf(mainSpaceShipPosition.x - enemySpaceShipPosition.x, 2) + powf(mainSpaceShipPosition.y - enemySpaceShipPosition.y,2); distance = sqrtf(distance); /* Distance > 250 --> no zoom Distance < 100 --> maximum zoom */ float myZoomLevel = 0.5f; if(distance < 100){ //maximum zoom in myZoomLevel = 1.0f; }else if(distance > 250){ myZoomLevel = 0.5f; }else{ myZoomLevel = 1.0f - (distance-100)*0.0033f; } [self zoomTo:myZoomLevel]; } -(void) zoomTo:(float)zoom { if(zoom > 1){ zoom = 1; } // Set the scale. if(self.scale != zoom){ self.scale = zoom; } } Basically my question is: How do I zoom the layer and center it exactly between the two ships? I guess this is like a pinch zoom with two fingers!

• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• Import SSIS Project in Denali CTP1

  For years Analysis Services has had the ability to take an existing database from a server and reverse engineer it into a BIDS project.  This is extremely useful when all you have is the running instance of the database and the project that created it has long since disappeared.  Reverse engineering has never been a feature of SSIS until now. Let me walk you through the simple steps. The first step is that you obviously have to have a project deployed to an SSIS Catalog.  I will do a video on this soon but in case you can’t wait then my good buddy Jamie Thomson has written it up here As you can see I have a project called imaginatively “Denali1” with one package “Package.dtsx” The next thing we need to do is fire up BIDS and choose the right project type (Integration Services Import Project) Now we just follow the wizard.  We make sure we specify on which server to find the Catalog and in which folder to look for the project. Next the setting are validated and we are greeted with the familiar review screen before the creation of our new project from the deployed project happens Hit Import and away we go The result is just what we wanted.

• Real-time stock market application

  - by Sam

  I'm an amateur programmer. I'd like to develop a software application (like Tradestation), to analyse real-time market data. Please teach me if the following approach is correct, ie the procedures, knowledge or software needed etc: Use a DB to read the real-time feed from data provider: what should be the right DB to use? I know it should be a time serious one. Can I use SQL, Mysql, or others? What database can receive real-time data feed? Do I need to configure the DB to do this? If the real-time data is in ASCII form, how can it be converted to those that can be read by the DB and my application? Should I have to write codes or just use some add-ins? What kind of add-in are needed? How should I code the program to retrieve the changing data from the DB so that the analysis software screen data can also change asynchronously? (like the RTD in excel) Which aspects of programming do I need to learn to develop the above? Are there web resources/ books I can refer to for more information?

• Possible to install Xmonad on Ubuntu separate from Gnome?

  - by Kurtosis

  I just downloaded Xmonad from the repository on my Ubuntu 10.04 box, but when I log out and try to log back in using Xmonad instead Gnome, it doesn't work. I just get the login screen background image and a mousepointer, and nothing else. Right-clicking does nothing, no menus or anything. Key combo's like Ctrl-X, Ctrl-Z, and Ctrl-Alt-Delete do nothing either. Left the computer in this state for 30 minutes while I went to the grocery store, but it was still hung when I returned and I had to hard-reboot it. A Google search returned a few sites showing how to configure Xmonad to work with Gnome, but I'm afraid to try this since I don't want to risk borking my Gnome installation, at least not until I've had a chance to learn Xmonad a bit. Is it possible to run Xmonad independently of Gnome? If so, anyone have any idea what might be wrong and how to fix it?

• Proportional speed movement between mouse and cube

  - by user1350772

  Hi i´m trying to move a cube with the freeglut mouse "glutMotionFunc(processMouseActiveMotion)" callback, my problem is that the movement is not proportional between the mouse speed movement and the cube movement. MouseButton function: #define MOVE_STEP 0.04 float g_x=0.0f; glutMouseFunc(MouseButton); glutMotionFunc(processMouseActiveMotion); void MouseButton(int button, int state, int x, int y){ if(button == GLUT_LEFT_BUTTON && state== GLUT_DOWN){ initial_x=x; } } When the left button gets clicked the x cordinate is stored in initial_x variable. void processMouseActiveMotion(int x,int y){ if(x>initial_x){ g_x-= MOVE_STEP; }else{ g_x+= MOVE_STEP; } initial_x=x; } When I move the mouse I look in which way it moves comparing the mouse new x coordinate with the initial_x variable, if xinitial_x the cube moves to the right, if not it moves to the left. Any idea how can i move the cube according to the mouse movement speed? Thanks EDIT 1 The idea is that when you click on any point of the screen and you drag to the left/right the cube moves proportionally of the mouse mouvement speed.

• HP Cue-Scanning Flow component freezes

  - by Nathan Fellman

  I am trying to scan with an HP network scanner (actually E6500 all-in-one). Whenever I try to scan, it starts up a flash screen with HP Scanning written all over it, which proceeds to do nothing. Digging in, I found that the process that gets stuck is hpqkygrp.exe, aka "HP CUE-Scanning Flow Component". This happened when I tried scanning from onenote or from the HP Solution Center. However, it seems that scanning from Windows' Fax and Scan utility works fine. As a (probably related) side-note, scanning directly from the scanner (using the buttons on its panel) doesn't work either. How can I keep this process from getting stuck?

• small light laptop with docking station that has a PCI(e) slot

  - by laramichaels

  Hi everyone, I am looking for a new laptop/netbook and I have two simple requirements: must be small (10-12in screen) and light (<=3-3.5pounds); must work with a dock into which I can put a PCI or PCI Express card. Basically, I have no performance requirements. Discontinued or low-end are fine. All I want is something easy to carry that when at work I can use a PCI/PCI Express card with to do multi-head. Eg, if an Acer Aspire 1410 fitted the second requirement I would by one in a blink. The only solution with which I am acquainted are Thinkpads that can go into the Thinkpad Advanced Dock. Do other laptop (or netbook brands) also offer the possibility of using Although this is not a "requirement" per se, I would rather hear about options that would not involve buying the latest-greatest-+$2k model... : ) Thank you for any advice! ~lara

• cocos2d/OpenGL multitexturing problem

  - by Gajoo

  I've got a simple shader to test multitextureing the problem is both samplers are using same image as their reference. the shader code is basically just this : vec4 mid = texture2D(u_texture,v_texCoord); float g = texture2D(u_guide,v_guideCoord); gl_FragColor = vec4(g , mid.g,0,1); and this is how I'm calling draw function : int last_State; glGetIntegerv(GL_ACTIVE_TEXTURE, &last_State); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, getTexture()->getName()); glActiveTexture(GL_TEXTURE1); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, mGuideTexture->getName()); ccGLEnableVertexAttribs( kCCVertexAttribFlag_TexCoords |kCCVertexAttribFlag_Position); glVertexAttribPointer(kCCVertexAttrib_Position, 2, GL_FLOAT, GL_FALSE, 0, vertices); glVertexAttribPointer(kCCVertexAttrib_TexCoords, 2, GL_FLOAT, GL_FALSE, 0, texCoord); glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); glDisable(GL_TEXTURE_2D); I've already check mGuideTexture->getName() and getTexture()->getName() are returning correct textures. but looking at the result I can tell, both samplers are reading from getTexture()->getName(). here are some screen shots showing what is happening : The image rendered Using above codes The image rendered when I change textures passed to samples I'm expecting to see green objects from the first picture with red objects hanging from the top.

• Multi-Resolution Mobile Development

  - by user2186302

  I'm about to start development on my first game for mobile phone (I already have a flash prototype completed so it's jsut a matter of "porting" it to mobile and fixing up the code) and plan on hopefully being able to get the game working on iphones and most android devices. I am using Haxe along with OpenFL and HaxeFlixel for development. My question is: What resolution should I design the game in initially and/or what is the best way to develop a game for multiple resolutions. I have found multiple different methods, the best, in my opinion, being strategy 3 on this page: http://wiki.starling-framework.org/manual/multi-resolution_development. However I have some questions about this. First, what would the best base resolution to use be, the guide suggests 240*320 which seems alright to me, although if I chose to use pixel graphics as I most probably will given I'm using HaxeFlixel, I'm not sure if they'll look too blocky on larger screens which I'm not even sure is a problem as it might still look alright. (Honestly, not sure about that and if anyone has any examples of games that use this method and look nice). Finally, please feel free to share whatever methods you use and think is best. For example, HaxeFlixel has a scaling feature that scales the game to fit the exact screen size, but I'm afraid that would lead to blurry and improperly scaled graphics since it would scale by non-integers. But, I'm not sure how noticeable a problem that may or may not be. Although from experience I'm pretty sure it won't look nice and currently I do not think I'm going to go for this option. So, I would really appreciate any help on this subject. Thank you in advance.

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

  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.

• IBM laptop remove access-connections

  I installed IBM Access Connections on my IBM t61 laptop to manage my wireless connections but it simply will not connect to my network. I want to uninstall it and try the Intel software which is capable to performing the same task. However, when I go into "Control Panel" - "Add/Remove Programs" and try to "Remove" this package, it simply opens up a screen and closes it immediately. This happens too fast for me to see whether its an error. Has anyone encountered this issue ? The event logs do not show any error.

• Kubuntu Monitor Out of Range

  - by uncleo

  My X server seems to be faulty, but I don't know why. I had some problems last week with a new motherboard, but they seemed to be resolved. Today, I updated Kubuntu and restarted, but my Viewsonic VX900 LCD monitor shows the splash screen for several seconds, then displays the message "Out of Range" I have tried various kernels in Grub, some in recovery mode, most do the same thing. No key combinations bring up a shell prompt like I expect. The one exception was a very old kernel, that would only mount the file system as read-only, so I can't fix up the xorg.conf file. Is there anything to be done?

• How to configure 1080p HDTV as a monitor

  - by Robot

  I've read several posts that almost answer my question, but not quite. I have a Samsung LN32C530 1080p HDTV I'd like to use as a monitor. I was reasonably successful getting the prior 720p model to work ok using SwitchResX, but I think I just got lucky with the parameters (1360x768@60Hz). I tried the expected (1920x1080@60Hz) values and "nearby" ones, with no luck. Older 720p params actually work, but I get the same small real estate as the older model TV. Trying values near 1080p always displays an image that doesn't match the screen size and is very jagged which makes me think interpolation is making things worse. Also, SwitchResX has a bunch of parameters other than H x W ("porch" etc), and I don't know how they all work together. Any help?
