• Direct2d off-screen rendering and hardware acceleration

  - by Goran

  I'm trying to use direct2d to render images off-screen using WindowsAPICodePack. This is easily achieved using WicBitmapRenderTarget but sadly it's not hardware accelerated. So I'm trying this route: Create direct3d device Create texture2d Use texture surface to create render target using CreateDxgiSurfaceRenderTarget Draw some shapes While this renders the image it appears GPU isn't being used at all while CPU is used heavily. Am I doing something wrong? Is there a way to check whether hardware or software rendering is used? Code sample: var device = D3DDevice1.CreateDevice1( null, DriverType.Hardware, null, CreateDeviceOptions.SupportBgra ,FeatureLevel.Ten ); var txd = new Texture2DDescription(); txd.Width = 256; txd.Height = 256; txd.MipLevels = 1; txd.ArraySize = 1; txd.Format = Format.B8G8R8A8UNorm; //DXGI_FORMAT_R32G32B32A32_FLOAT; txd.SampleDescription = new SampleDescription(1,0); txd.Usage = Usage.Default; txd.BindingOptions = BindingOptions.RenderTarget | BindingOptions.ShaderResource; txd.MiscellaneousResourceOptions = MiscellaneousResourceOptions.None; txd.CpuAccessOptions = CpuAccessOptions.None; var tx = device.CreateTexture2D(txd); var srfc = tx.GraphicsSurface; var d2dFactory = D2DFactory.CreateFactory(); var renderTargetProperties = new RenderTargetProperties { PixelFormat = new PixelFormat(Format.Unknown, AlphaMode.Premultiplied), DpiX = 96, DpiY = 96, RenderTargetType = RenderTargetType.Default, }; using(var renderTarget = d2dFactory.CreateGraphicsSurfaceRenderTarget(srfc, renderTargetProperties)) { renderTarget.BeginDraw(); var clearColor = new ColorF(1f,1f,1f,1f); renderTarget.Clear(clearColor); using (var strokeBrush = renderTarget.CreateSolidColorBrush(new ColorF(0.2f,0.2f,0.2f,1f))) { for (var i = 0; i < 100000; i++) { renderTarget.DrawEllipse(new Ellipse(new Point2F(i, i), 10, 10), strokeBrush, 2); } } var hr = renderTarget.EndDraw(); }

• GRUB2 prompt instead of BURG boot screen after mistake during BURG installation

  - by Tomas Lycken

  I just installed BURG, but during the installation I made a mistake: after the package was installed, I got to some command-line based GUI for configuration, where I forgot to mark my (only) hard disk as the boot device before I hit OK. I tried to reinstall (apt-get purge burg && apt-get autoremove followed by apt-get install burg) but I wasn't able to get to the same screen again (I didn't find the GUI). When I now start my computer, I am taken to a GRUB2 prompt and no BURG (or GRUB2) boot menu is shown. Since I don't know any GRUB commands and I am helpless. How do I reinstall GRUB/BURG correctly? Update: I rebooted my computer, and got a BURG prompt (which appears to be the same thing as a GRUB prompt, but if there's a difference I wouldn't know it...). I have booted from a Live USB, but I don't know what to do next. The text above has been updated to reflect this new situation - for the original text, please see the previous versions of this post.

• Black Screen after Resume from Sleep (Kubuntu)

  - by user20271

  I know there is a lot of other posts like this, but I have been looking for hours and I still haven't found any solution. I have recently installed Kubuntu Linux along side my Windows 7, the sleep on my Win7 works fine and resumes like normal. When I am loaded into Kubuntu, and I put my laptop to sleep, it goes into sleep as normal. When I go to RESUME from the sleep, the screen stays solid black, it doesn't light up, no blinking curser or anything. The Wi-Fi light is 'off' (orange) and I cannot turn it on. The Caps lock and the Num lock lights on the keyboard blink slowly. I hear something on the inside of the computer start to spin. I am not very experienced with Kubuntu/Linux, but I do know a bunch of computer terminology, I am still far from an expert though. I have about 300GB designated to my Win7 stuff, and another partition with about 100GB for my Kubuntu Linux. My computers specs are as follows: Windows 7 64-bit I have the most recent version of Kubuntu because I just downloaded it a few days ago and updated it yesterday. AMD Athlon Duel-Core processor 4GB of RAM And it is a HP G61 Laptop

• No "Choose OS" screen after co-installation of Ubuntu 12.04

  - by Léon McGregor

  I don't have any technical knowledge of Ubuntu but wanted to install it on a partition. Step-by-step of what i did. used disk management in windows 7 to clear 50gb of space used a usb live ubuntu 12.04 installer in custom install mode used the installer's built in disk manager to set up 2gb swap space and 48gb ext4 space ran installation, with option to copy over documents and settings from windows 7 restarted after completion. After this, my computer automatically loads ubuntu 12 and skips the option to load windows 7. i know the files are still there, as i can see them in the file manager. When trying to fix with the win7 installer dvd it tries to repair the OS in drive [D:] i.e. it recognises the disc itself as the OS and ignores the [c:] files. I think, after browsing around here, similar problems suggest this is a problem with the boot loader, but if the win7 dvd won't work, then i don't have any way to fix this. does anyone know of a way to force the computer to show a "choose OS" screen?

• Trouble installing Server 12.10 - Dead keyboard, Blank Screen, Network Config

  - by Mikey

  Installing 12.10 server from cd - minimal installation: basic system, ssh server,postgreSQL, manual updates. Hardware is brand new HP server that also runs Win 2003 Server Standard as a DNC excellently - I installed the grub boot manager on the primary partition and it is working fine - can boot to Win or Ubuntu without issue. Everything seemed to go OK on the installation - BUT when I restarted the system after install and booted to Ubuntu, I got the command prompt for Ubuntu, but the keyboard was UNREPSONSIVE - dead. There is nothing wrong with the keyboard - works fine if I boot to Win. With a completely unrepsonsive keyboard I had to hit the power switch - when I restarted and booted to Ubuntu, Ubuntu started but no command prompt came up at all - just black screen. I powered down and rebooted to advanced Ubuntu options - it tried to reinstall/initliaze a long list of packages - when it got to 'waiting for network configuration' it waited, then a message 'waiting 60 seconds for network configuration'... it waited 60 seconds and then I got a 'failed to configure network message' and it continued. Finally it finished, I hit enter and got to a prompt - but again, keyboard UNREPSONSIVE - dead. I went through this several times - tried 'repairing broken installation' option and also reinstalling entirely - always same results. I am flummoxed. The only clue I have is that for the Windows DNC config, the IP address is static - not via DHCP. But I don't think that should impact Ubuntu at all - perhaps I am mistaken. What is wrong?

• Matte or non-widescreen laptop? Do they exist?

  - by Alan Harris-Reid

  Does anyone know of any matte-screen laptops being sold now (15.6 or 17") in the UK? All I can find is the Dell Vostro 3500/3700 range, but there is a premium of around £200 over the price of their Inspiron range (for the 17" model), and I find it hard justifying the extra cost just to have a matte screen. I do not like glossy screens, but it seems the laptop industry has gone the way of "glossy is better - let's get rid of matte". I have read and heard from other developers that as long as there are no strong light sources to reflect off the screen, one can soon get used to a glossy screen, but I am yet to be convinced. I would also be interested if anyone knows of any non 16:9 screen laptops. I find this ratio too wide and not high-enough for the work I do. 16:10 or lower would be better. Any opinions would be appreciated. Alan

• Stuck on EULA screen when installing netflix-desktop

  - by Jim

  I am trying to install netflix-desktop on my laptop running 13.10. I followed the instructions here: sudo apt-add-repository ppa:ehoover/compolio sudo apt-get update sudo apt-get install netflix-destop After a while, there is a EULA in my xterm that says I must agree to it to get the software. At the bottom of the screen there is ' I have hit , 'A', , typed 'OK' in that xterm but it never gets past that. The application is not available because if I try to launch netflix-desktop in another xterm, it doesn't know what I'm talking about and netflix isn't found on my system when I search search. Can anybody tell me what I'm supposed to do next or what I should have done so that I'm not in this situation next time? Thanks! Solution: I found out that I had to hit the down arrow several times till the lit up. Then I could hit to go to the next step. Then by using the arrow keys to highlight the proper respose(s), I was able to complete the installation. I haven't actually brought up Netflix yet, but it appears to be installing things as expected.

• Making a 2D game with responsive resolution

  - by alexandervrs

  I am making a 2D game, however I wish for it to be resolution agnostic. My target resolution i.e. where things look as intended is 1600 x 900. My ideas are: Make the HUD stay fixed to the sides no matter what resolution, use different size for HUD graphics under a certain resolution and another under a certain large one. Use large HD PNG sprites/backgrounds which are a power of 2, so they scale nicely. No vectors. Use the player's native resolution. Scale the game area (not the HUD) to fit (resulting zooming in some and cropping the game area sides if necessary for widescreen, no stretch), but always fill the screen. Have a min and max resolution limit for small and very large displays where you will just change the resolution(?) or scale up/down to fit. What I am a bit confused though is what math formula I would use to scale the game area correctly based on the resolution no matter the aspect ratio, fully fit in a square screen and with some clip to the sides for widescreen. Pseudocode would help as well. :)

• Screen Resolution stuck at 640x480 after installing Bumblebee

  - by Saurabh Agarwal

  I have a Dell XPS 15z laptop. As you can see here, there are some issues with NVidia drivers. The site recommends installation of Bumblebee (instructions given in the link). I am posting it again for ease: $ sudo add-apt-repository ppa:bumblebee/stable $ sudo apt-get update && sudo apt-get upgrade $ sudo apt-get install bumblebee bumblebee-nvidia $ sudo usermod -a -G bumblebee $USER After restarting the computer however, the screen resolution was stuck at 640x480 and I got the following error message as soon as I logged in: **Could not apply the stored configuration for monitors** none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 1) Prior to the update, the display was absolutely normal and thus there is no doubt about the cause. Albeit, there was no support for graphic drivers. In case it helps, some features of graphics drivers seem to be functional after bumblebee, ie, all features are in order except for the resolution. And if the resolution can't be fixed, please suggest a way to retract the changes so that atleast the prior state may be reachieved. Any help in the matter would be highly appreciated.

• Technique to have screen independent grid based puzzle with sprite animation

  - by Yan Cheng CHEOK

  Hello all, let's say I have a fixed size grid puzzle game (8 x 10). I will be using sprites animation, when the "pieces" in the puzzle is moving from one grid to another grid. I was wondering, what is the technique to have this game being implemented as screen resolution independent. Here is what I plan to do. 1) The data structure coordinate will be represented using double, with 1.0 as max value. // Puzzle grid of 8 x 10 Environment { double width = 0.8; double height = 1.0; } // Location of Sprite at coordinate (1, 1) Sprite { double posX = 0.1; double posY = 0.1; double width = 0.1; double height = 0.1; } // scale = PYSICAL_SCREEN_SIZE drawBitmap ( sprite_image, sprite_image_rect, new Rect(sprite.posX * Scale, sprite.posY * Scale, (sprite.posX + sprite.width) * Scale, (sprite.posY + sprite.Height) * Scale), paint ); 2) A large size sprite image will be used (128x128). As sprite image shall look fine if we scale from large size down to small size, but not vice versa. Besides the above mentioned technique, is there any other consideration I had missed out?

• OpenGL (glx) not working with ubuntu 12.10

  - by user26766

  It all started when I installed nvidia's own (download from website) driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode. Here are some outputs: glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig glxgears Error: couldn't get an RGB, Double-buffered visual optirun glxgears works fine lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff) Here's the content of log file when just after running glxinfo: less /var/log/Xorg.0.log | grep gl [ 112.156] (II) LoadModule: "glx" [ 112.157] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so [ 112.157] (II) Module glx: vendor="X.Org Foundation" [ 112.157] (II) UnloadModule: "glx" [ 112.157] (II) Unloading glx [ 112.157] (EE) Failed to load module "glx" (module requirement mismatch, 0) Some more info... lsmod Module Size Used by bbswitch 13612 0 pci_stub 12623 1 vboxpci 23195 0 vboxnetadp 25671 0 vboxnetflt 23480 0 vboxdrv 320372 3 vboxpci,vboxnetadp,vboxnetflt parport_pc 32689 0 ppdev 17074 0 bnep 18141 2 rfcomm 46620 12 binfmt_misc 17501 1 snd_hda_codec_hdmi 32049 1 snd_hda_codec_realtek 78147 1 joydev 17458 0 uvcvideo 76750 0 videobuf2_core 32852 1 uvcvideo videodev 120310 2 uvcvideo,videobuf2_core videobuf2_vmalloc 12861 1 uvcvideo videobuf2_memops 13405 1 videobuf2_vmalloc snd_hda_intel 33492 3 coretemp 13401 0 kvm_intel 132760 0 arc4 12530 2 snd_hda_codec 134213 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel kvm 414111 1 kvm_intel iwlwifi 386837 0 i915 520799 2 snd_hwdep 17699 1 snd_hda_codec snd_pcm 96668 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec psmouse 100389 0 drm_kms_helper 49113 1 i915 ghash_clmulni_intel 13221 0 snd_seq_midi 13325 0 snd_rawmidi 30513 1 snd_seq_midi btusb 22475 0 drm 288436 3 i915,drm_kms_helper serio_raw 13216 0 snd_seq_midi_event 14900 1 snd_seq_midi snd_seq 61555 2 snd_seq_midi,snd_seq_midi_event mac80211 535936 1 iwlwifi bluetooth 209249 22 bnep,rfcomm,btusb snd_timer 29426 2 snd_pcm,snd_seq snd_seq_device 14498 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78921 16 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device cfg80211 206797 2 iwlwifi,mac80211 aesni_intel 51038 1 cryptd 20404 2 ghash_clmulni_intel,aesni_intel aes_x86_64 17256 1 aesni_intel dell_wmi 12682 0 sparse_keymap 13891 1 dell_wmi dcdbas 14439 0 i2c_algo_bit 13414 1 i915 microcode 22804 0 lpc_ich 17062 0 soundcore 15048 1 snd snd_page_alloc 18485 2 snd_hda_intel,snd_pcm video 19391 1 i915 mac_hid 13206 0 wmi 19071 1 dell_wmi mei 40691 0 lp 17760 0 parport 46346 3 parport_pc,ppdev,lp ahci 25721 3 libahci 31192 1 ahci atl1c 41102 0 how can I fix this? any ideas?

However I didn't find any obvious link to /lib/nvidia-current in /etc/ld.so.conf (where the directories containing the shared libraries are listed). I don't know if there's anything missing or if this is normal. thanks, UPDATE: The problem was solved by updating to Ubuntu 13.04. It seems bumblebee was to blame, but I'm not sure what was going wrong...

• I need acpi=off to boot, but this seems to disable wifi

  - by TheExp3rt

  To boot my computer, I have to use acpi=off in kernel options. Doing this apparently causes my wifi adapter to be switched off and prevents my mouse and USB keyboard to not work. If I change acpi=off to nomodeset, it fixes these problems. But then it sets my computer at a lower resolution. I am currently running Kubuntu 13.10, although none of the updates, starting from 12.04, changed the need for acpi=off. I assume I need acpi=off in because I have an oldish computer with an intel motherboard How can I boot without acpi=off?

• Creating user UI using Flixel

  - by Jamie Read

  I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. What I am trying to do is add a Start Screen before actually loading the game. I have a create function that adds all the game elements to the stage: override public function create():void // all game elements { How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add. Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great. Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } } Thanks.

• Ubuntu 12.04 freezes when booting

  - by Agustín González

  Translated I installed Ubuntu 12.04 LTS from the LiveCD, after finalizing the installation process and booting correctly, I applied the pending updates, which asked me to reboot. After rebooting, an error appeared saying "Out of Range". I pressed CTRL+ALT+F1, login to the tty1 terminal and edit the xorg.conf file and add VertRefresh 50.0 - 60.0 to it, which would solve the "Out of Range" problem that was mentioned before. After applying the changed and rebooting again, the following boot screen is all I see now: It freezes there. I even waited 2 hours and nothing happened. Can anybody help? Thank you! Original Instale Ubuntu 12.04 LTS desde el Live CD, al finalizar la instalación inicio el sistema operativo e inicia correctamente, después de aplicar actualizaciones me solicita reiniciar en lo cual acepto. Al volver a iniciar me daba un erro de "Fuera de rango", aprieto CTRL + ALT + F1, me logueo y edito el archivo xorg.conf en la sección Screen y agrego "VertRefresh 50.0 - 60.0", lo cual solucionaría el problema de "Fuera de rango", al aplicar los cambios, vuelvo a iniciar y solamente me aparece la pantalla de inicio (Véase imagen: http://t.bb/fH) y queda colgado, lo deje por lo menos 2 horas así y nada sucedió. ¿Alguien puede ayudarme? Gracias!

• How to install nvidia drivers (GT 440 ) on Xubuntu 12.10 , screen res gone to 640x480 :(

  - by shaggyjack

  Hi all after days of endless googling I finally gave in and decided to try and directly ask for help. I have just installed Xubuntu and updated to 12.10 on a pretty old (12 years) machine, and I am now struggling to install the correct drivers for the nvidia 440 gt card.. I have managed to get "additional drivers" but the app does not show in the menu, I went through a few procedures which ended up in my screen going no higher than 640x480, and tried all the sudo apt-get variations with nvidia-current and current updates... I think I got the right version of the drivers ( 93.43.07 ) but they won't install from terminal as they say I am running an X server. So I learnt how to shut the graphic interface but then I try and install them from there but after I write the exact same command (sudo home/username/Downloads/NVIDIA-Linux-x86-96.43.07.pkg1.run ) nothing happens and the terminal says something like command not found. I am desperate for help if anybody could point me in the right direction that would be greatly appreciated. There are lots of similar topics on installing nvidia drivers but I seem to understand that current drivers are no good for my old GPU. So if anybody could show me how to install the right version that would be excellent. Thanks in advance! Jack

• Multiple monitors showing same screen but different resolutions

  - by Luis Alvarado

  Is it possible to have 2 or more monitors showing the same screen, for example the same desktop but with different resolutions. Like the clone option in Nvidia or the mirror option using the Display settings in Ubuntu but instead of showing the same output with the same resolution, the both show the same output using a resolution that is native for each monitor connected. In my case if I have a netbook that has max resolution of 1360x768 and a TV that has 1280x1024, the would both show the same desktop but each with their own resolution that is compatible for each device. This would help in trying to find a resolution that works on both monitors and in cases like a mini netbook and a huge TV it would solve issues like having max 800x600 in one monitor and min 1024x768 in the other. In the case I tested I was using an HDMI cable but this question also involves VGA and any other connection. I have 3 tests scenarios for this: Scenario 1 - Laptop HP DV6000 (Intel Integrated Video) with 1360x760 connected to a Samsung LED 42 TV that has 1280x900. Scenario 2 - Laptop EEE with 1024x600 (Intel Integrated Video) connected to Sony LCD TV that supports 1280x900. Scenario 3 - Intel Desktop with Nvidia 440 GT with HDMI connected to Soneview 32' TV that supports 1920x1080 and VGA connected to an Epson Video Beam that supports 1280x1024 max. In this 3 scenarios I need to be able to show the same desktop and same views but on different resolutions for each output device. UPDATE: Tested with Xubuntu and the way it handles multiple monitors is precisely what I am asking. The ability to handle the resolution of different monitors showing the same thing.

• Ugly Boot Screen after upgrading to 12.10

  - by Sir Linuxalot

  Is there a way to change the ugly boot screen in 12.10? It seems to have rolled back to that 8-bit blocky looking thing with tiny orange dots underneath. It then breaks into process code under that, and it looks ghastly. I've read some tutorials on getting Plymouth to do some neat things, but they were for older versions of Ubuntu. I'm running a GeForce GTX 460 if that matters. Any help would be appreciated. Update: I've noticed/found a couple of things. The upgrade on my laptop didn't do this. It still uses the "normal" Ubuntu boot logo (using Plymouth, I assume). So, something is off with my desktop. And, I found and installed Super Boot Manager to see if that would help. With that, I enabled Plymouth and added a new theme, but the machine still boots with the block-ugly logo. Finally, I messed around with Grub on boot and added "nomodeset" after "quiet splash" and added it while deleting "quiet splash." None of these solutions worked. I'll keep hunting...

• Your Most Popular Sites Screen in IE 10 - Icons not appearing

  - by MJWadmin

  We use the following code to add icons for favicon, tablets, smartphones, windows 8 tiles and the like:- <link rel="apple-touch-icon" href="apple-touch-icon.png"> <link rel="shortcut icon" type="image/x-icon" href="/favicon.ico"/> <link rel="apple-touch-icon-precomposed" sizes="144x144" href="apple-touch-icon-144x144-precomposed.png"> <link rel="apple-touch-icon-precomposed" sizes="114x114" href="apple-touch-icon-114x114-precomposed.png"> <link rel="apple-touch-icon-precomposed" sizes="72x72" href="apple-touch-icon-72x72-precomposed.png"> <link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png"> <meta name="msapplication-TileImage" content="apple-touch-icon-144x144-precomposed.png"/> <meta name="msapplication-TileColor" content="#17151a"/> Unfortunately this doesn't seem to work for IE9 and IE10's 'your most popular sites screen', google searches have been un-enlightening. Stack uses <link rel="apple-touch-icon" href="apple-touch-icon.png"> which seems to work for it, but not for us. Any clues to a solution appreciated.

• Ubuntu does not recognize my built-in monitor.

  - by B3tturTh3nU

  I've recently discovered of a boot problem Ubuntu has with my laptop. I have successfully installed Ubuntu on two other computers, and I've never experienced this problem. What happens is, after the live boot CD loads, the screen goes completely blank. Although, I suspected that there was no problem booting, so I loaded with BIOS only, which worked perfectly fine. Of course, not being very proficient with this, I have no idea what needs to be done to fix the problem. I have switchable graphics cards(the ATI Mobility Radeon HD 5650, and some low-end Intel card), and an Intel i5 quad core processor. I was booting with the Ubuntu 10.10 64 bit desktop distribution. If there's any more information you need from me, please let me know. EDIT: I was able to look into this a bit more, thanks to one of the comments provided, and I have some new information. Ubuntu does seem to be able to recognize both of my graphics cards. The problem I found was that, in the Xorg.0 log, it mentions that there were "no screens found." I'm using a notebook, so the screen is built in. Does anyone know of a way to get Ubuntu to recognize the monitor?

• Laptop Display Not Working

  - by etrask

  Hello, I just purchased this laptop. It is working fine but I want to use Xubuntu on it. I managed to get 10.04 installed and running but it did not recognize/use the wireless card. So I want to try 10.10. However, every time I try, the screen goes black and never comes back on. I have tried the Live CD and Alternate install CDs, for both Ubuntu and Xubuntu 10.10. After I select "Install Ubuntu" or "Try Ubuntu", the screen blacks out and never displays anything. So I deleted "quiet" and "splash" off the command line to see what messages would come up. A bunch of text flies by but it ends at: [time] TCP established hash table entries: 524288 (order: 11, 8388608 bytes) [time] TCP bind hash table entries 65536 (order: 8, 1048576 bytes) [time] TCP: Hash tables configured (established 524288 bind 65536) [time] TCP reno registered [time] UDP hash table entries: 2048 (order: 4, 65536 bytes) [time] UDP-Lite hash table entries: 2048 (order: 4, 65536 bytes) [time] NET: Registered protocol family 1 And freezes here forever. I have tried nomodeset, vga=771, and xforcevesa with no progress. Is my video card simply not going to work with this distro? It seems strange that 10.04 would work fine but not 10.10. Any help is appreciated, thank you.

• Geekswithblogs.net | Screen Resolutions of our Readers

  - by Jeff Julian

  Yesterday I talked about the Browsers we see being used by our readers driven off of our Google Analytics traffic and today I want to share with you the Screen Resolutions we see.  As a web developer most of my life, it is hard to decide how large you should build your application because typically you have a couple huge high resolution monitors on your desk, but you typical end user is thought to have 1024x768.  With HTML5/CSS3 out, it is a little better coming up with a design that will scale to all resolutions, but it is still nice to know the numbers when it comes to how much real estate do I have on my clients. If you look at these numbers for Geekswithblogs.net, we have a lot of high resolution monitors from users that visit the site.  After a little more investigation of the number you will notice we do not have as much height available as we do width.  If the primary goal of a site is to deliver as much data in the viewable area without scrolling, this becomes a challenge when most of our pages have long pieces of formatted data.  So our challenge is to build skins that use up more of the sides of the content toward the top on larger resolution browsers and then entice the reader to scroll to get the goodies embedded in the content of the posts.  Going to be an interesting battle for sure, but we really need more skin offerings on the site.

• 1080p Screen resolution problem after 10.04 to 12.04 update

  - by Ale

  I have a Samsung LCD 40" with a NVidia GeForce 6150SE nForce 430 Card. I recently upgraded from 10.04 to 12.04 and the best resolution I can get is 1360x768. I've tried the propietary drivers available on the repository kmod:nvidia_current kmod:nvidia_173_updates kmod:nvidia_current_updates kmod:nvidia_96 kmod:nvidia_96_updates kmod:nvidia_173 I've also downloaded latest from NVidia's Web, version: 295.40. But still no luck. With Nouveau driver, I can only get 1024x768. I know there is no problem with my hardware (video card, cable and monitor), I was using it perfectly on 10.04. Can anybody suggest something else I could try, to get my 1920x1080 resolution back? Thanks in advance. Here are some more information, that I got reading other similar posts on askubuntu. $ lspci | grep VGA 00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1360 x 768, maximum 1360 x 768 default connected 1360x768 0 0 0mm x 0mm 1360x768 50.0 52.0* 1024x768 51.0 800x600 53.0 54.0 55.0 680x384 56.0 57.0 640x480 58.0 576x432 59.0 512x384 60.0 400x300 61.0 62.0 63.0 320x240 64.0
