  • Remmina remote control: black screen after XBMC exit

    - by Tinellus
    I have a HTPC (Quietpc Sidewinder Fanless media pc) running Ubuntu 12.04 and autostarting XBMC Frodo. I'm remote controlling this machine using my laptop also running Ubuntu 12.04 and using Remmina VNC as a client. Everything works perfectly as long as XBMC is running: I can see the remote screen and control via mouse and keyboard on the laptop. However, when XBMC is stopped on the HTPC, my TV shows the Ubuntu desktop normally, but the screen on the laptop turns black. I'm however still controlling the HTPC since I can see the arrow moving upon laptop mouse movement, and I can still type text in the HTPC. Oddly, when the screensaver on the HTPC kicks in, I again have a visual on the laptop. Anyone any thoughts on this? What should I do to maintain visual after stopping XBMC? Any suggestions much appreciated. Thanks!

  • Live CD boot/installation problem, blank screen - 12.04

    - by traubi
    I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom) I checked the live system with my laptop.works well except it also starts of with a black screen and a grey box at the bottom. I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters. I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text. I would be happy for any advice on this matter

  • Black Screen When Booting From .VDI Image

    - by GTyler
    I have cloned a VirtualBox machine, which runs Ubuntu 11.04 32-bit as Guest OS. I now wish to transfer it to a new host machine running Windows Vista 32-bit. I’ve transferred the .vdi file and adjusted the name and memory. However when I boot it, the options to choose the Linux version came up: Ubuntu, with Linux 2.6.38-10-generic, Linux 2.6.38-10-generic(recovery mode) , Previous Linux versions, Memory test. Once I chose Linux 2.6.38 a black screen just appears with an underscore at the top. What should I do to get it to run? I don’t have my original machine near me now so I can only work with my .vdi image. My VB is version 4.0.10. I have tried cloning this VDI and also assigning a new UUID and making a new guest, but I still got the black screen. Thank you.

  • Ubuntu Splash Screen Customization

    - by Galaxy7
    I wanted to know how to customize the splash screen in Ubuntu 13. I have tried to install Plymouth Manager but when I run sudo apt-get update it says it was unable to fetch http://ppa.launchpad.net/mefrio-g/plymouthmanager/ubuntu/dists/raring/main/binary-i386/Packages. I opened the address in Firefox but it didn't open. Also I would like to know where the files for the Ubuntu Logo, Splash Screen Background, etc. are located (to customize them). In previous versions they were located at usr/share/images. I am running Ubuntu 13 Raring Ringtail on VMWare Player. The host is an Acer 5600U running Windows 8. Thnx.

  • All video players display black screen.

    - by Dennis
    I'm working in 10.04 Lucid. All my video players (Movie Player and VLC) and the preview windows in editors (OpenShot and Pitivi) will only display a black screen when playing a video. The sound is fine and the videos work fine on other computers. I have tried multiple formats from varying sources .MOV taken from old ffmpeg projects, .AVI straight from a camera, .MP4 using h.264 from OpenShot on another system, .OGV from a gtk-recordmydesktop session on this very computer. I even get a pure black screen in the viewer when starting a remote session in VNC. This box has a GeForce 8400 GS using the Nvidia drivers in case it may be a card problem or setting.

  • XNA frame rate spikes in full screen mode

    - by ProgrammerAtWork
    I'm loading a simple texture and rotating it in XNA, and this works. But when I run it in full screen 1920x1080 mode I see spikes while my texture is rotating. If I run it windowed with 1920x1080 resolution, I don't get the spikes. The size of the texture does not seem to matter, I tried 512 texture size and 2048 texture size, same thing happens. Spikes in full screen, no spikes in windowed, resolution does not seem to matter, Debug or Release does not seem to do anything either. Anyone got ideas of what could be the problem? Edit: I think this problem has something to do with the vertical retrace. Set this property: _graphicsDeviceManager.SynchronizeWithVerticalRetrace = false; you'll lose vsync but it will not stutter.

  • Startup a Ubuntu FTP and SSH server without logging in

    - by Jenko
    I have a Ubuntu Server 11.10 box, which I would like to run "headless", and without a keyboard, mouse or display. Is it possible that immediately after startup the machine logs into an account, or allows me to control the machine from my Windows 7 machine nearby via SSH and SFTP? I've got OpenSSH server installed, and even when the box is not logged in I can start an SSH session. I've tried installing VSFTPD but its very troublesome (hardly connects) and only starts when I login locally into the box.

  • Multitouch screen needs two touch points

    - by BloodPhilia
    So, I got a netbook (Some weird China brand) and it has a multitouch screen. I got to installing Ubuntu Netbook 10.10 and I used the mouse and keyboard for that. When I wanted to try the touchscreen, at first it didn't seem to work, then I tried to multitouch, and this is what happens: I put my finger on point A I put my finger on point B, while still holding point A. The cursor now jumps to the location on the screen where point A is touched. I can now use point A to drag the cursor ONLY when holding point B. I can use point B for clicking by tapping, but ONLY when holding point A at the place I want to click. What is going on?

  • DockbarX inside AWN, preview window shifted on dual-screen after shifting from single-screen.

    - by naaronne
    I've been running dockbarx in AWN for sometime now. I started using dual-screens and started seeing a problem with the window preview. When I hover over the dockbarx icon to see the preview it appears on the other monitor. I'm assuming that this is due to it still thinking there is only one monitor. I was hoping someone new of a gconf-editor setting that I could set with the rest of my screen that changes my laptop from internal monitor to my dual-screen setup. Thanks in advance.

  • Ubuntu 13.10 won't boot and hangs on a black screen

    - by Anonymous John
    I installed Ubuntu 13.10 64-bit today and I sat on the internet most of the day after installation. I shut the computer down and went bowling with my family. When I came back, I turned on my computer and it came to the boot screen as usual, but then the screen went black and stayed black. Can this be solved or do I have to install Ubuntu 13.04. My dad does not know about this and I do not want to get yelled at for an hour, so I need an answer before midnight mountain time, otherwise I will install Ubuntu 13.04 so I won't get yelled at in the morning.Thanks to anyone who answers this.

  • How do I disable network connection at prelogin?

    - by ProGNOMmers
    --- This question is related to Ubuntu 12.10, since previous versions did not connect to network before login --- I had a bad boot today: the Ubuntu screen was blocked at startup time, after a green [OK] and a white blinking underscore. In recovery mode I figured out the problem: NetworkManager hung trying to connect to a wireless network that wasn't available anymore, and so I couldn't reach the prelogin level. Anyway: I really don't like that the pc connects to a network before the user logging in. How is it possible to disable it?

  • C# XNA Make rendered screen a texture2d

    - by redcodefinal
    I am working on a cool little city generator which makes cities in the isometric perspective. However, a problem arose where if the grid size was over a certain limit it would have awful lag. I found the main problem to be in the draw method. So I took the precautionary step of rendering only items that were onscreen. This fixed the lag but, not by much. The idea I have is to render the frame once and take a snapshot. Then, display that as a texture2d on screen. This way I don't have to render 1,000,000 objects every frame since they don't change anyways. TL;DR - I want to Take a snapshot of an already rendered frame Turn it into a Texture2D Render that to the screen instead of all the objects. Any help appreciated.

  • Lubuntu notifications extend off screen

    - by cbojar
    I just installed a fresh Lubuntu 12.04. When notifications pop up in the corner, longer ones seem to extend off-screen and get cut off. Shorter ones do not have this problem (I'm assuming they draw from a fixed corner at top left and dynamically extend). My screen resolution is correct and no other applications seem to have this problem. I've even changed the resolution and the problem persists (at both resolutions). Is there any way to fix this? Is there a max-width setting or something that might need adjusting?

  • Pendrive USB Ubuntu installation - black screen on boot

    - by ubuntico
    I see many posts on this, but no solution. I installed Ubuntu 12.04 on my 16GB USB flash drive using this official link using their tool Universal USB Installer. Installation to USB went fine so I set my laptop to boot from USB and the Ubuntu was recognized. I saw the usual boot screen and I chose option "Run Ubuntu from this USB". The boot process started and after 5-6 seconds the screen goes black and non-responsive. I thought that it hang on X loading so I tried switching to console via Ctrl+Alt+F1-6 but the system did not respond. Why is this happening? Am I doing something wrong? PS. My laptop is HP Pavillion G6

    I am using Ubuntu 10.04 LTS, dual boot with win7 on ThinkPad T400, I followed Ubuntu update hints and installed some update for my ATI Radeon graphic card, but when I boot to Ubuntu(means I can still load GRUB), the tragedy happened, the screen goes to blank and no matter what key stroke, I can not get any responds, I try to go to text terminal, but impossible! However when I hit the power button, the computer would pop out the Ubuntu shutdown screen briefly and shut down. I figure out I should delete the updates package of my graphic card, but I don't even get a chance to go to text terminal, please help me!

  • Ubuntu 12.04 LTS - Black Screen at boot After changing Nvidia Driver

    - by nDman
    2 days ego i updated my Ubuntu 12.04 LTS to latest updates but i ignored Grub Updating because I thought it will clear my grub settings (I'm so noob!). After restart every things was right, the Ubuntu started normally and every things was working well except graphic which had problem before update. I had the experimental driver before but I changed it to the current-update version. After restart Ubuntu stock on black screen. I tried to reinstall Nvidia driver from recovery but it not worked. Then i used Update Grub in recovery, it not worked too but i see this line on screen at boot: at this time it stops and keyboard not working, but when I push the power button it shows these lines and it will shutdown. OK finally I made it start with older kernel (3.5.0-28-generic). Now how can I keep this kernel or fix Ubuntu to work with new kernel? Should I reinstall Nvidia driver? Which version should I use?
