  • Blue Screen Dilemma

    - by Joscine
    Ok, I burnt a cd and a jump drive and I want to install Ububtu on a windows xp computer. But the computer keeps showing the blue screen.... "a problem has been detected and windows has been shut down to prevent damage to your computer" Is there any way I can install Ubuntu still? Do I have to fix windows to be able to install it? And if so, does anyone know how to fix it? I don't have the windows installation pack.

  • Mouse pointer position to screen space

    - by Ylisar
    If I have a mouse pointer position in pixels of canvas, I can easily convert it to the -1..1 range for both X & Y by lerping by dividing with canvas dimensions. However, the problem is what I should put in Z & W if I want my screen space position to be on the near plane? The step afterwards would be for me to multiply by the inverse of view-projection to take me to world space, where I easily can construct a ray from the cameras world space position.

  • Get your picture on the screen at MIX11: Help me create a repository of sample data

    - by Laurent Bugnion
    Here is your chance to get your picture on the big screen during my MIX11 presentation in April this year. I need to create a small repository of sample data for my demos. So instead of tapping in my imagination and creating dummy users (or reusing past information I already used in other demos), I thought I would appeal to the amazing community: Send me an email with the following information. I will include the first 30 users into my sample data repository and use your info in my demo. First Name Last Name Date of birth Picture Link to Facebook profile (optional) Disclaimer: The data will only be running locally on my hard drive. The demos will however be filmed and the videos made public. By providing this information, you explicitly consent to this data being used in demos at MIX11 and possibly in following conferences. The data will only be used for demo purposes. Thanks for your help!!   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Maximal screen resolution for external monitor breaks desktop

    - by Robiston
    Whenever I'm plugging in my external monitor into my notebook and changing the screen resolution to the maximum state, the desktop will get broken in a way: A third of the whole desktop space is not visible at all. I can see the whole panel as well as the Unity side bar to the left, but the desktop space with all the windows in it is not completely visible. It's blanked out. In case of opening the Unity menu bar, I can type something in it. As soon as close the menu bar, the upper part stays visible and hangs: Any ideas about that issue?

  • Flashing screen hovering over menubar on left side

    - by iwekb
    Just installed Ubuntu 10.10 netbook version on an older Dell Laptop (no other operating system installed). When hovering with mouse over menu bar, the full screen changes to default coloured back ground shortly and then back to normal (as after start-up) again. And that each time the mouse is over any of the (default) icons on the menu bar. I am not able to select any icon. No left or right click works on icons or anywhere on the menubar apart from the left top small icon, white Ubuntu logo, and the right top small icons for WiFi, sound, mail, shut-down etc. Those icons work. I tried re-installation again and all patches are downloaded. Same problem. Problem is that I can't enter commands either to reduce e.g. the swappiness (if that would be of any help). Can somebody help me that encountered similar problem or knows a resolution?

  • Inserting x200s into (ultrabase) docking station mirror screen is always activated leading to non optimal resolution

    - by kiu
    Builtin LCD should be 1440x900 External LCD should be 1920x1080 If X200s is inserted into docking station the option mirror screen is always activated leading to a resolution of 1152x864 which looks terrible on the builtin and external lcd. My manual configuration for docking mode (seperate screens with maximum resolution) should be respected, but "Make Default" button has no consequences. Found a quick fix, but this cant be the offical ubuntu way... /etc/udev/rules.d/99-vga.rules: SUBSYSTEM=="drm", ACTION=="change", RUN+="/usr/local/sbin/vga_changed.sh" /usr/local/sbin/vga_changed.sh: #!/bin/bash dmode="$(cat /sys/class/drm/card0-VGA-1/status)" export DISPLAY=:0.0 if [ "${dmode}" = disconnected ]; then /usr/bin/sudo -u kiu /usr/bin/xrandr --output LVDS1 --mode 1440x900 --pos 0x0 --output VGA1 --off elif [ "${dmode}" = connected ]; then /usr/bin/sudo -u kiu /usr/bin/xrandr --output LVDS1 --mode 1440x900 --pos 0x0 --output VGA1 --auto --mode 1920x1080 --right-of LVDS1 fi

  • laptop screen goes blank after waking from sleep

    - by Tojo Chacko
    I have been facing this issue from the last week after some update. Whenever my laptop wakes up from suspend state it just shows me a blank screen. Regardless of whatever I do(move my mouse, press keyboard buttons) it just refuses to wake up. I am forced to do a restart and lose all my unsaved files. Has this issue been reported for Ubuntu 12.04? I am using a Lenovo X200 with Intel Mobile 4 Series Graphics Chipset. Please let me know if any body has found a fix for this.

  • Installing Ubuntu 13.10 'Saucy Salamander' on L75D-A7280 hangs on a black screen

    - by Riven
    Trying to get Ubuntu 13.10 to work and it will not. Seen that somebody is having a similar problem, some things failing then it just hangs on a black screen (after pressing F1 to see what it's doing). My system is a Toshiba Satellite L75D-A7280, and I have tried two different files that I had downloaded from Ubuntu.com with no luck. My laptop came with Windows 8 and following the dual-boot directions Ubuntu 12.04 was installed and worked perfect, except for completely obliterating Windows 8 and voiding my warranty, meaning neither Toshiba nor the retail center I bought my system from can help me legally, besides giving advice... nor can I return it to get a non-UEFI based system. I really need to figure this out, I am a student and need my laptop working properly with any OS I put on it. Will continue searching for any information I can find.

  • No splash screen on hibernate

    - by Marky
    Hibernate is working fine. A bit slow when resuming from a hibernate but I can bear with it just so that I have all open applications on the desktop as I left it. Then again the "slowness" might be because of the 4GB RAM, although I'm assuming only what is used gets swapped and not the entire memory. Going back, my question is has anyone been able to make Ubuntu show a splash screen or some kind of indicator/progress bar to show while hibernating or while resuming? I remember with SuSE on my HP Compaq Presario notebook it had messages appear during and after. Better than nothing, I guess. Thanks in advance! :D

  • How do I screen-capture an inactive window?

    - by Wassasin
    How can I screen-capture an inactive (minimized / on another workspace) window in Ubuntu? Applications like ImageMagick's import are only able to capture active windows. When attempting to capture an inactive window, I get the following message: unable to read X window image `<id>': Resource temporarily unavailable @ error/xwindow.c/XImportImage/5023. Might be able to do this using Compiz, as it is able to render previews of inactive windows. Furthermore, in my specific case, the window I want to capture is run in a Wine Explorer-container. Inside that container the application is always active.

  • Mouse on screen lags

    - by Jeggy
    I just made a fresh install of Ubuntu 13.10 64bit on my Dell XPS 15 laptop. My mouse lags/glitches/blinks each time something is loading in Ubuntu. when a youtube video is playing in the background it blinks all the time, and it also blinks for each character that I write, it's very annoying. It also blinks for each time the Blinking Cursor in a text field blinks. When I have just booted up my laptop it can be away for a second or more (than after it comes back it goes away for a second or more and this happends for awhile), so I have no chance of seeing the mouse on my screen.

  • Screen Resolution Problem with Ubuntu 14.04 and VirtualBox

    - by user3341257
    Environment: Lenovo T530 running Windows 7. Have installed Ubuntu 14.04 on a virtual machine using VM Virtual Box. Have installed all the updates from both Virtual Box and Ubuntu. Problem: While in Ubuntu's desktop and other Ubuntu initiated programs, the window is reduced to about 3x4 inches showing in the middle of the rest of my regular Virtual Box window. I am seeing only the upper right hand of the screen output of what I would normally see. Please help. I've seen How do I install Guest Additions in a VirtualBox VM? But, none of these answers works in 14.04.

  • background animation algorithm for single screen

    - by becool_max
    I’m writing simple strategy game (in xna), and would like to have an animated background. In my game all the actions happens inside one screen and thus standard parallax effect does not look appropriate. However, I found a video of a game with suitable background animation for my game http://www.youtube.com/watch?v=Vcxdbjulf90&feature=share&list=PLEEF9ABAB913946E6 (from 3 to 6s, while main character stays at the same place). What is the algorithm to do this stuff? It would be nice if someone can provide a reference for a similar example (language is not important).

  • 12.04 install now just blank screen

    - by bull
    I have attempted to install a new copy of 12.04 using usb stick instead of using download manager. Everything went fine while using usb stick until I restarted after installation was complete. Then, I got the screen with cursor and 4 lines of script with the first line saying "could not write to bytes: broken pipes". I have used several versions of Ubuntu from 6.04, but this one seems broken. I have tried nouveau.blacklist and many other suggestions to no luck. I am using hp pavilion m7790y dual core processor system, with nvidia 7600gt video card, 4gb ram and two hard drives with Vista on one and fresh install of Ubuntu 12.04 on other. I'm still looking for help to solve this problem. Thanks in advance.

  • Videos stutter in full screen

    - by user85256
    Using Ubuntu 12.04 with Gnome 3.4.2. When I load video files (avi, mkv, mp4), they play smoothly in windowed mode, but when in full screen, they mildly (but noticeably) stutter. I've tried various players (from VLC to SMplayer2), with many different output drivers and it's always the same. Also, my video card is AMD Radeon HD 6450, and I've had no luck with the proprietary FGLRX drivers. Every time I install them, my system becomes very sluggish (window dragging animations become choppy etc.). Thanks in advance, guys.

  • Blank screen after logging in

    - by Dnarlock08
    I just installed the 64 bit version onto my laptop. It is the only operating system on the computer. After the initial setup and restart, I tried to log in, but after I typed my password and hit enter, the screen just went black. Tried to restart several times and had the same problem. Not sure what to do. I tried to use the 32 bit version instead but it doesn't even install. My computer is 64 bit, 200 g hard drive, 2 ghz processor, 4 g ram

  • Manually change the screen resolution

    - by Dz WarSoldier
    My system: Ubuntu 12.04 LTS. My graphic card: nVidia GeForce gt430. My monitor is Samsung LE26R51B. And my connection is digital (HDMI). The current screen resolution is not good at all, I can't see the top bar and the left one. Here are the available resolutions in settings: 1920*1080 1280*720 960*600 and lower resolutions But with no one of these I can see the top bar in it. They are bigger than the monitor. In Windows 7 I use 1202*670 resolution. How can I change the resolution to what I want exactly?

  • Create a overflow screen while a game/program is running?

    - by Dodi300
    Hello. Does anyone know how I can create a screen overflow while a program is running? Mainly while a game is running. If anyone has used xFire or Steam, these use this feature. I've created a winform which starts the game/program and then minimizes. Could the overflow be created in the same winform? Thanks for the help! :)

  • BlackBerry - How to add content to the Home Screen? (Today plugin?)

    - by Devguy
    Hi guys, in the WinMobile world you can create a so called Today plugin to add content to the phone's main screen, the one where you see the number of missed calls, unread sms and upcoming events. Is it possible to do something similar on the BB? I'd like to show some important info there, so that they are as visible and easily reachable as possible. I hope this is something that can be done with Java and the JDK...
