  • Changing the rendering resolution while maintaining the design layout

    - by Coyote
    I would like to increase the FPS of my project. Currently I would like to try reducing the resolution at which the scenes are rendered. Let's say I never want to draw more than 1280*720. What ever the real resolution is. How should I proceed? I tried pEGLView->setFrameSize(1280, 720); but only reduces the displayed size of the frame on screen (boxing). In my activity I tried setting the size of the "surface" but this seems to completely break the layout (as defined by setDesignResolutionSize). @Override public Cocos2dxGLSurfaceView onCreateView() { Cocos2dxGLSurfaceView surfaceView = new Cocos2dxGLSurfaceView(this); surfaceView.getHolder().setFixedSize(1280, 720); return surfaceView; } Is there a way to simply change the rendered

  • Is it only possible to display 64k vertices on the monitor with 16bit?

    - by Aufziehvogel
    I did the first 3D tutorial over at riemers.net and stumbled upon that my graphic card only supports Shader 2.0 (Reach profile in XNA) which means I can only use Int16 to store the indices (triangle to vertex). This means that I can only store 2^16 = 65536 vertices. Also I read on the internet that you should prefer 16-bit over 32-bit because not all hardware (like mine) does support 32-bit. Yet, I am wondering: Do really all game scenes get along with only so little vertices? I though already faces of people used a lot of polygons (which are made up of vertices?). It’s not relevant for me yet, but I am interested: Do game scenes use only 65536 vertices? Do you use some trade-off to display more (e.g. 64k in GPU buffer rest on RAM) Is there some method to get more into the GPU buffer? I already read on some other posts that there seems to be a limit of 64k per mesh too, so maybe you can compact stuff to meshes?

  • What can I change/investigate where the install does not complete?

    - by tunist
    I have already successfully installed Ubuntu 10.10 on my laptop and it works fine. I attempted to get my desktop PC to dual boot Windows and Ubuntu but found that neither the 32 or 64 bit install images will boot/install successfully. The startup script locks on 'initializing core #2' (or 1 or 3).. once I saw it say 'ok' at the end but it still locks there. I have tried to change the boot sequence by inserting 'debug' and 'acpi-off' into txt.cfg in both isolinux and syslinux folders but no changes were obvious during the boot.. as far as it got. The pc is built with an abit IP35 motherboard and nvidia 8600GT gfx card. Does anyone have any suggestion of what else I can change to get the install working?

  • Ghosting Program for Ubuntu 12.10

    - by Sean Webber
    I am looking to figure out how to set up a mass backup system for a computer network (of about 25) and am looking for a ghosting program that makes an image of the entire system for backup/recovery purposes. While clonezilla would work.. you have to manually boot us the CD for it. I am looking for a program that runs INSIDE Ubuntu that sends a system image backup off to the network server at set times, then when needed could also be used to burn the clone back to the machine. Another words- automatically and the only time I have to do anything to it is when I need to burn a backup BACK to a 'crapped' machine. Any ideas?

  • Steam not displaying text on wine 1.5 running on Ubuntu 12.04

    - by Jscags
    Hello fellow dwellers of askubuntu, as the title says I'm having difficulties with getting Steam to run properly. I think I have the solution but I am pretty incompetent with Ubuntu (just started using it the other day) so a step by step process would be unbelievably appreciated! Here are the links to what I think possible solutions are: [1] https://bbs.archlinux.org/viewtopic.php?id=146223 [2] http://bugs.winehq.org/show_bug.cgi?id=31374 I've tried googling how to preform the solutions such as changing the alias/script for steam (no idea what that is) to -no-dwrite or launching with wine Steam.exe -no-dwrite. The dwrite seems to be the issue in all this but I can't for the life of me figure out how to do anything about it. Any useful input is what I'm hoping for but for the brave soul who feels like typing a bit more, perhaps a step-by-step list of instructions starting from downloading Steam off the official website, would be my saving grace. If there is any more info you guys need let me know and I'll of course be happy to oblige!

  • Problems after upgrading from 10.04 to 12.04

    - by Paul D
    I upgraded to 12.04.1 from 10.04 recently and am running the Gnome Classic (no effects) desktop. I spent a couple of days tweaking the appearance and behaviour but there are two issues that I can't resolve. The mouse cursor frequently disappears, especially when scrolling through web pages or hovering over links/icons with tooltips. Moving the mouse brings the pointer back but it vanishes again almost immediately. Note I don't have unclutter or Parallels installed. The screen no longer fades to black when left idle for too long - it just cuts out. Bad news when watching content online. Any tips greatly appreciated. Cheers...

  • Gnome 3 freezes when switching workspaces

    - by Bill Cheatham
    I have found an odd problem with Gnome 3 on Ubuntu recently. Under certain circumstances, when switching between two workspaces the whole desktop and user interface will 'freeze' for anything up to 2 minutes; during this time I cannot click anything or interact using the keyboard. Often, the screen will show a 'half-completed' animation of the workspace swapper. This is on Ubuntu 12.04.1 running on a 2-year old Macbook Pro, and it only seems to occur when using an external monitor. This does not seem to be a processor or memory issue, and does not occur every time I switch workspaces. Is this a known problem? What can I do in the short or long term to fix it?

  • Not able to create Live CD

    - by Jagannath Harati
    I downloaded 12.04.1 on a Windows 7 machine. I burnt a DVD from the ISO image using Windows Disc Image Burner. I had 'verify disc' on. The disc was created successfully with no errors. I was not able to use this disc for installing Ubuntu on another Windows 7 machine. I do not get the Welcome Screen on booting. I find that on the disc I burnt, I do not find bin, disc tree, programs directories and cdromupgrade, start.*, ubuntu* files. I found the boot directory and WUBI executable file. I tried downloading several times with the same result. I had similar problem earlier with 11.04. Can you please let me where the problem is?

  • Monitor not recognised after apt-get upgrade on 11.10 - maximum 1024x768 resolution

    - by Josh
    I did an apt-get upgrade through update manager on 11.10. After restarting my VGA monitor is no longer recognised and I can only get a maximum of 1024x768 on a 1440x900 monitor. I can't find xorg.conf so I am pretty lost! xrandr output: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 DVI-0 disconnected (normal left inverted right x axis y axis) S-video disconnected (normal left inverted right x axis y axis)

  • Creating Ubuntu bootable disk on my phone

    - by Aerus
    I want to install Ubuntu 12.04 on my laptop but because I have a complete shortage of writable CDs and DVDs, I wan't to create a bootable USB stick (on Windows). However, the only USB stick I currently have lying around is my HTC phone (HTC Touch HD with 8Gb memory). I was following the Ubuntu guide to create a bootable usb stick with pendrivelinux, however in the last step it shows me that it wants to do more than just copying the .iso file to the USB drive: My question: can I safely proceed without wiping the current OS off my phone (Windows Mobile 6.1) and use it to install Ubuntu?

  • Need help with AMD catalyst control center

    - by user254074
    I just built my first HTPC and I hooked it up to my Sony KDS-R60XBR1 and I am having display issues. I believe this is only a 1080i display and when I select 1920x1080 on the resolution I get strange lines on the display when anything moves on screen. I am guessing this is because it is putting it in 1080p and the TV cannot process that. As of now I have lowered the resolution and that worked but I would like to get this set at 1080. Also I cannot change the underscan. I am stuck with black borders around the display image. When I pull up the catalyst control center on my computer I am able to adjust all of this stuff but on the one on my HTPC with the TV display I have no options. See images below.

  • Blank desktop after login

    - by Alex
    Today my 14.04 updated itself not requiring a reboot. After a while I rebooted because of other reasons and then I was pleasantly surprised by a blank screen. I have tried everything I could think about including Reinstalled compiz, unity, ubuntu-desktop, xorg Reinstalled and then removed the nvidia driver So far nothing has worked. Except for one little thing: my cairo-dock is showing. And that's all. I tried with Unity doesn't load, no Launcher, no Dash appears, but none of the answers there helped me. I also tried removing my ~/.Xauthority file and it still doesn't work. Does anybody know what else I could try? UPDATE: sudo dpkg-reconfigure xserver-xorg sudo service lightdm stop sudo service lightdm start When I run that code and then login again the icons on the desktop are displayed but the menu and the launcher are still not there. Also, when I try to run an application from CTRL + ALT + F1 such as dconf reset -f /org/compiz/ it says Cannot autolaunch D-Bus without X11 $DISPLAY I can only run applications with export DISPLAY=:0

  • Ubuntu 12.10 install freezes at configuring hardware

    - by Max Keener
    I'm installing Ubuntu 12.10 (64 bit) from a bootable USB stick. At first I had trouble with a black screen after selecting 'install ubuntu'. I added nomodeset and xforcevesa to the options to fix that problem. Now when installing, it hangs at 'Configuring Hardware', specifically at ubuntu ubiquity: update-initramfs: Generating /boot/initrd.img-3.5.0-17-generic Specs: Asus UX32a DB51 Intel Core i5 3317U 1.7 GHz 4GB DDR3 RAM intel hd 4000 graphics 500 GB harddrive with 25 GB sandisk ssd I'm trying to install Ubuntu by itself right now on the SSD. I made custom partitions (100 mb EFI boot partition, 4GB swap space, 20GB ext4 mounted on '/') I've tried re-downloading the ubuntu iso and creating a new boot image on my flash drive and it results in the same problem. Thanks in advance for the help!

  • Preseed Ubuntu installation with full disk encryption

    - by user249264
    I am trying to set up Ubuntu full disk encryption using preseeding. I was able to set things up correctly following the preseed file presented here. But I do not want to provide the default password in the preseed file. Is there a way to let ubiquity fall to the screen that asks for the encryption passphrase just like it does when the username is not provided in the preseed file? When I try to leave the passphrase option empty in the preseed file, I get an error in the installer saying "An error occured while creating the keyfile".

  • How do I find a proprietary driver for the Intel graphics card I have?

    - by user69798
    I have an Intel corporation core processor integrated graphics controller (rev 18), and I am trying to get a proprietary driver for my graphics card so I can play Amnesia from the Humble Bundle. I am a female that can easily follow directions but doesn't know much about Linux yet. If you give me precise directions, I will follow them so you can help me fix the problem. I would really appreciate it! My laptop is a Dell n7010. Additional info: I believe that it is the graphics card that is causing Amnesia to crash, but I am unsure. I have tried running it on the lowest possible settings, and it crashes after the first loading screen. :( Also, I installed via the Ubuntu Software Center after purchasing the Humble Bundle. I have not tried the other games yet.

  • Upgrading an app to support iOS5, 6 and 7

    - by drekka
    We are looking at an app that needs an upgrade. Currently it runs on iOS4, 5 & 6. The upgrade will move to iOS5, 6 & 7. It will also involve some UI changes and new features. I've been reading stuff on iOS7 and looking at things like auto-layout. What we are trying to figure out is the best way to handle the differences between the various iOS versions. Auto-layout seems like a good idea, but it's not available on iOS 5. There are also API changes to consider between all 3 versions and other new features of iOS7. So the questions: How would you handle auto layout given iOS5 does not have it? Are there any significant differences between the SDKs that you think would cause issues? Would we be better off with separate code bases?

    How can you rotate a quad around its center? This is what im trying to do but it aint working: GL11.glTranslatef(x-getWidth()/2, y-getHeight()/2, 0); GL11.glRotatef(30, 0.0f, 0.0f, 1.0f); GL11.glTranslatef(x+getWidth()/2, y+getHeight()/2, 0); DRAW my main problem is that it renders it off the screen.. draw code: GL11.glBegin(GL11.GL_QUADS); { GL11.glTexCoord2f(0, 0); GL11.glVertex2f(0, 0); GL11.glTexCoord2f(0, getTexture().getHeight()); GL11.glVertex2f(0, height); GL11.glTexCoord2f(getTexture().getWidth(), getTexture().getHeight()); GL11.glVertex2f(width,height); GL11.glTexCoord2f(getTexture().getWidth(), 0); GL11.glVertex2f(width,0); } GL11.glEnd();

  • GRUB not showing /dev/sda2 is Windows 7 Loader

    - by Ricardo
    A few days ago I accidentally deleted Ubuntu partition using GParted. I thought Windows 7 would start normally, but I got a "grub-rescue" screen instead. Then, I recreated a partition for Ubuntu (/dev/sda6) and reinstalled it. Ubuntu starts properly now; but GRUB shows me /dev/sda2 is Windows Recovery System (WRS), what is false, since /dev/sda1 is WRS and /dev/sda2 is Windows 7 Loader. I booted using Windows 7 disk and tried to correct this problem automatically and by bootrec.exe /fixboot and /fixmbr, and nothing is able to fix my problem. Yet, Windows (disk) says there is no OS in my computer. What should I do? Will I have to erase my hard disk to get Windows 7 back?

  • Ubuntu 12.04 keeps rebooting after changing video settings

    - by ScottJShea
    In a pinch I had to install Ubuntu 12.04 on an HP Pavilion g6. I was not fond of the 1024 x 7678 resolution so after investigating and finding I had the intel chipset I set the below in the grub file: GRUB_GFXMODE=1366x768x32 GRUB_GFXPAYLOAD_LINUX=1366x768x32 This did not work. The system just keeps rebooting as nauseum. I powered down, inserted my Ubuntu Install USB, powered up, edited the Grub file on the disk (made sure it was the disk and not the Grub for the USB stick). Powered off and tried booting up again. Same thing. So: As a noob am I missing something in the boot to allow me into a recovery mode? (I cannot seem to get to the Grub menu) If not is there a way I can recover from this? UPDATE: Holding down the shift key after BIOS gets "GRUB Loading..." and then a reboot

  • error: no device connected

    - by Prabath Swarna
    I did a fresh install of 12.04 and it went fine, worked on it for several days, but one day the browser crashed and i reset the machine, after that I get this error when i boot; error: no device connected error: no device connected error: no device connected error: no device connected This comes after the BIOS confirmation, and it stays for about 30 seconds, then the grub menu comes and when I selected the default the screen becomes purple and stays like that for a whole Minuit. I thought maybe that is because I have 500GB HDD so i ran the boot-repair, It did nothing at all. I'm sure I did the boot-repair thing right, sorry I forgot the paste URL. If i reinstalled will this error persist.

  • How can I use rhythm box and conky together?

    - by Ryuzaki
    I'm still fairly new at this and 12.04 LTS is my first hands on experience with Ubuntu all together. After spending a few weeks and trying to learn the in's and out's of the OS, I'm actually finding it easier to use in my off-time than Windows. However, my question today deals with the following: I need help in trying to pull information from Rhythm Box in order to display it using Conky. What I want is the following: » Album Title » Song Name » Artist » Album Picture Is there a way to pull these and display them so that they will change as the songs change? I tried my hardest but I'm still a noob when it comes to using terminal and coding.

  • HELP: I Broke Ubuntu By Uninstalling Compiz

    - by tSquirrel
    I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it. sudo apt-get remove compiz sudo apt-get install compiz I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04 How can I fix it? I'm not even sure how to get to a terminal or anything. The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how. Please Help! Right now I'm working off my W7 dualboot.
