  • Grub2 attempting to boot hd1 when it should boot hd0

    - by JoBu1324
    I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

  • My game seems to be incompatible with recording software. What could be causing this?

    - by Lewis Wakeford
    I've just finished a little Game-Dev project for university and I need to record a video to accompany my submission (just in case they can't get my source to work). Basically my game doesn't work at all when FRAPS or Bandicam attempts to attach to it, I get a black screen and a stream of GL INVALID OPERATION messages from my error reporting code. Dxtory can't seem to hook into it correctly at all, it doesn't display it's FPS counter or anything. My game logic appears to be running correctly from the debug traces, it just seems like all the gl library calls break. I don't know a huge amount about how these programs operate so I don't really know what I could be doing to cause this. I've heard they read from the OpenGL frame buffers so maybe I'm doing something wrong there? I'm letting GLFW and GLEW do all the low level initialization, but I have successfully recorded projects with the same setup and recording software. Essentially, has anyone ever run into something like this before or do you know anything about how these programs work that could give a clue as to the cause of the issue?

  • Ubuntu on Samsung NP700Z5B - no Grub

    - by copolii
    I just bought a Samsung NP700Z5B laptop. Gorgeous machine and great performance! I do 2 things when I get a new laptop: Format the HD and install Winblows from a CD to ditch the bloatware Install some variant of Linux on it (lately Ubuntu) Step 1 worked fine (until earlier today), but I haven't been able to install Ubuntu on it for the past 3 days! I've tried Mint12, Ubuntu 12.04, Ubuntu 11.10, Ubuntu 11.04 and Ubuntu 10.04. The live CD and the installations all run fine and report no problems, but when I reboot grub is nowhere to be found! The system goes directly to Winblows! I've tried booting from the liveCD and re-installing grub via the chroot and purge & reinstall methods (https://help.ubuntu.com/community/Grub2) and neither makes a difference. I've also tried copying the boot sector: dd if=/dev/sda of=linux.bin bs=512 count=1 and putting it on c: then setting bcdedit to add the entry to the Windows bootloader with no results. Earlier today I decided to try and set my boot partition as an EFI boot partition ... bad choice, now I don't even have the Winblows boot loader. I've officially ran out of ideas. Tried calling Samsung, but they're closed (they'd probably say something stupid along the lines of "Samsung recommends Windows 7" ... I've had Dell say that to me). Any help would be greatly appreciated. Update 1 Tried re-installing 12.04 and now I get the screen continously turning off and back on, but still no sign of booting ... it has been doing it for 15 mins so far (I set the boot partition type to ext2 instead of ext4) Update 2 Well ... this just gets better and better. I inserted the installation USB key to reboot it and the flickering stopped for about a minute (remained on) then it started turning off and on again

  • What to do when 'dpkg --configure -a' fails with too many errors?

    - by rudivonstaden
    During an upgrade from lucid (10.04) to precise (12.04), the X session froze, and I have been trying to recover the upgrade to get a stable system. I have performed the following steps: Used ssh to log in to the stalled system over the network. Checked the contents of the /var/log/dist-upgrade directory. There was no activity on main.log, apt.log or term.log. top showed that process 'precise' was using about 3% CPU, but I could find no evidence that the upgrade process was still doing anything. 'dpkg' did not show up in top, but it came up with pgrep dpkg | xargs ps Killed the 'dpkg' and 'precise' processes Tried to recover the upgrade by running sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a. This was partially successful (some packages were configured), but failed with the message Processing was halted because there were too many errors. I ran the same command a few times, and each time some packages were configured but others failed. Tried running sudo apt-get -f install. It fails with similar errors to dpkg. The current situation is that dpkg --configure -a and sudo apt-get -f install fails with two kinds of error: Dependency issues, e.g.: dpkg: dependency problems prevent configuration of cifs-utils: cifs-utils depends on samba-common; however: Package samba-common is not configured yet. dpkg: error processing cifs-utils (--configure): dependency problems - leaving unconfigured Resource conflict, e.g.: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable Additionally, it seems there's reference to potential boot problems, so I'm not keen to reboot without fixing the install first: dpkg: too many errors, stopping Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab So my question is, how to get a working install when dpkg --configure -a fails?

  • Shutting down Ubuntu 11.10 with power button without x11-session

    - by RJdaMoD
    when pressing the power-button inside a (gnome-)session, ubuntu asks me what to do and shuts down after 60 seconds anyway. No problem so far. But if i'm not logged in in a gnome-session (for example in the login screen), or just change to a tty, then the power-button won't work. But i remember that i worked in 11.04. So what's changed and how to restore? Background: I use my machine as a print server. If im not home and my wife wants to print sth., she used to switch on my machine, print via her laptop, and then just shut it down by power-button. Beginning of march i was on a business tour, and she called me that she could not shutdown my machine anymore. I shut it down by ssh, but this seems not the favorable way to me. I already had a look in /etc/acpi/powerbtn.sh and think that the line if pidof x $PMS > /dev/null; then exit is the cause for this since it aborts the script when no gui-power-manager is found. Is that right? But that does not explain with the power-button does not work when switching from the x11-session to a tty, although this would not be critical to me. Thanks in advance Greetings RJ

  • Couldn't pass the signin screen on ubuntu

    - by Amokrane
    I have an issue here with my computer using ubuntu 10.10 on a 64 bits machine. When I start it, I have the login screen, I enter my credentials but instead of starting the session it reloads the login screen again. I checked the disc using fsck and it seems clean. How should I proceed to diagnose and repair this issue? Thanks! [Edit] I went to the log files, this is what I got: auth.log pam_unix (gdm:session): session opened for user amokrane by (uid=0) pam_ck_connector (gdm:session): nox11 mode, ignoring PAM_TTY :0 pam_unix (gdm:session) :session closed for user amokrane messages.log No ACPI video bus found I also took a shot with my camera of the black screen that appears between the two login screens, it says something like: fsck from util-linux-ng 2.17.2 /dev/sdc4 : propre, xxxx files, xxxx blocs Starting AppArmor profiles Skipping profiles in /etc/apparmor.d/disable: usr.bin.firefox Setting sensors limits Starting postgreSQL ... /var/log/Xorg.0.log [ 25.375] (II) intel(0): Modeline "1920x1080"x60.0 172.80 ...

  • Developing my momentum on open source projects

    - by sashang
    Hi I've been struggling to develop momentum contributing to open source projects. I have in the past tried with gcc and contributed a fix to libstdc++ but it was a once off and even though I spent months in my spare time on the dev mailing list and reading through things I just never seemed to develop any momentum with the code. Eventually I unsubscribed and got my free time back and uncluttered my mailbox. Like a lot of people I have some little open source defunct projects lying around on the net, but they're not large and I'm the only contributor. At the moment I'm more interested in contributing to a large open source project and want to know how people got started because I find it difficult while working full time to develop any momentum with the code base. Other more regular contributors, who are on the project full-time, are able to make changes at will and as result enter that positive feedback cycle where they understand the code and also know where it's heading. It makes the barrier to entry higher for those that come along later. My questions are to people who actively contribute to large opensource projects, like the Linux kernel, or gcc or clang/llvm or anything else with say a developer head count of more than 10. How did you get started? Was there a large chunk of time in your life that you just could dedicate to working on the project? I know in Linus's case he had a chunk of time (6 months) to get it started. What barriers to entry did you encounter? Can you describe the initial stages of the time spent with the project, from when you had little understanding of the code to when you understood enough to commit regularly. Thanks

  • Over-scan Issues when using HDTV through VGA

    - by RPG Master
    Right now all we can do is set the TV to 1280x768 instead of its native resolution of 1360x768. Setting it to its native resolution gives you a screen with a large portion of the left side of the screen cut off. We've tried everything with the TV so now we're turning to the innards of Ubuntu in hopes of fixing this. The computer is using an NVIDIA GeForce GT240.

  • Offshoring: does it ever work?

    - by DanSingerman
    I know there has been a fair amount of discussion on here about outsourcing/offshoring, and the general opinion seems to be that at best it is difficult, and at worst it fails. I have direct experience of offshoring myself; a previous company where I was a dev manager wanted to send some development offshore, and we ran a pilot scheme to see how well it would work. Of course it was a complete failure, although it is not completely clear to me whether this was down to the offshore devs being less talented, the process, or other factors (no doubt it was really a combination). I can see as a business how offshoring looks attractive (much lower day rate), but as far as I can see, the only way it could possibly work is if you do exceptionally detailed design up front, with incredibly detailed specifications; and by the time you have invested in producing that, you have probably spent as nearly as much as if you had written the actual code locally (which I think is an instance of No Silver Bullet) So, what I want to know is, does anyone here have any experience of offshoring actually working ever? Especially if there are any success stories of it working in a semi-agile way? I know there are developers here from all over the World; has anyone worked on an offshore project they consider successful?

  • C++ Succinctly now available!

    - by Michael B. McLaughlin
    Over the summer I worked with SyncFusion to create an eBook based off of my C# to C++ guide for their free Succinctly Series of eBooks. Today the result, C++ Succinctly, was published for download. It is a free (registration required; they make tools and libraries for .NET development so you might get an occasional email from them – I’ve been signed up for a few months and have had maybe 3 emails total so it’s not horrible super spam or anything ) and you can download it as a PDF or a Kindle .MOBI file (or both). I’m excited with how it turned out and enjoyed working with the people at SyncFusion. The book contains a total of 20 code samples, which you can download from BitBucket (there’s a link very early in the book). Almost all of the code is also inline in the book itself so that you don’t need to worry about flipping back and forth between your dev machine and your eReader (but if you want to try to understand a concept better, you can easily download the code, open it up in VS 2012, and play around with it to see what happens when you tinker with things). The code does require Visual Studio 2012 because of its expanded support for C++11 features and since I wrote all of the samples as Console programs for clarity and compactness, you will need a version that supports C++ desktop development (currently VS 2012 Pro, Premium, or Ultimate). Sometime this Fall, Microsoft will be releasing Visual Studio 2012 Express for Windows Desktop which should provide a free way to use the samples. That said, I tested all of the samples with MinGW and only the StorageDurationSample will not compile with it due to the thread-local storage code. If you comment that out then you can compile and run all the samples with MinGW (or using a recent version of GCC in a GNU/Linux environment, or any other C++ compiler that provides the same level of C++11 support that Visual Studio 2012 does). I hope it proves helpful to those of you who choose to check it out!

    i am having an sony E series laptop.i have an HDMI port .at this stage ,i have tested my sound card , which provides audio out on my laptop i.e i could hear songs .my laptop has two sound cards amd 5450 and an intel-hda(alsamixer shows that as s/pdif) . i decided to connect HDMI output to my new HD-TV.but, i could get only visuals on my TV,NO AUDIO OUTPUT ( HDMI cable works fine with win 7).my laptop has two sound cards.but i couldn't switch output to other card.( i don't know ,how to do that) i decided to update alsa. complied the following code in terminal. sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily sudo apt-get update sudo apt-get install alsa-hda-dkms then,strangely no login sound, and no audio output on my laptop at all .then, started complied code from step1 sound troubleshooting procedure from offical ubuntu site.then, my speaker icon taskbar disappeared .obivously $aplay -l ,provided output as no soundcards detected . so , i implemented step 4 from that guide, it provides a output of all hardware devices in my laptop. *-multimedia UNCLAIMED description: Audio device product: Cedar HDMI Audio [Radeon HD 5400/6300 Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list configuration: latency=0 resources: memory:f0040000-f0043fff *-multimedia UNCLAIMED description: Audio device product: 5 Series/3400 Series Chipset High Definition Audio vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 05 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f5e00000-f5e03fff that command displayed output name of the two cards . but , still i have no positive output on $aplay -l. so therfore, i think alsa couldn't detect my sound cards . is there solution to this problem? it could be better,if alsa would channel output from multiple sound cards ? how should install and configure alsa such that detects HDMI cable as soon i connect to my HD tv? is it possible to alsa and pluseaudio 2.0 to co-exist, if so how?

  • Xorg crashes ever since using Nvidia dual monitors

    - by legion
    Well ever since I have used dual monitors with the NVIDIA X Server Settings program my xorg process has been crashing after a while, and its generally a pretty long while of like 6 hours afterwards. Before NVIDIA changed my xorg.conf file I only had xorg crash like twice in 2 months, I can't figure out what is going on. I am running ubuntu 12.04 with the MATE desktop environment v 1.2.0 xorg.conf # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@allspice) Fri Mar 30 15:25:24 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "LEN" HorizSync 51.8 - 55.8 VertRefresh 40.0 - 60.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "NVS 3100M" EndSection Section "Screen" # Removed Option "TwinView" "0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+0" # Removed Option "TwinView" "1" # Removed Option "metamodes" "DFP-1: nvidia-auto-select +0+0, CRT: nvidia-auto-select +1920+0" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinViewXineramaInfoOrder" "DFP-1" Option "TwinView" "0" Option "metamodes" "DFP-0: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection

  • htaccess and htpasswd trouble

    - by hjpotter92
    This is the first time that I have ever tried working with .htpasswd and .htaccess files, so please point out my childish works. I have my apache document root set to /www/ on my debian server. Inside it, there's a folder named Logs/ which I want to restrict access using a htpasswd. I created my htpasswd file using the shell's htpasswd command. And this is the result: > user:<encoded password here> > hjp:<encoded password here> > hjpotter92:<encoded password here> I put this file named .htaccess inside /www/. The Logs/ has following htaccess file in it: > AuthName "Restricted Area" > AuthType Basic > AuthUserFile /www/.htpasswd > AuthGroupFile /dev/null > require valid-user This was again created using an online tool(I forgot its name/link, and can't search the browser-history now). The problem, as it might've already struck you is that I am experiencing no change on my Logs folder access. The folder is still accessible to everyone. I am running apache as root user(if that matters/helps). Please help/guide me. I've tried reading some htaccess guides and have followed some of older SO questions, but still haven't figured out a way to restrict access to Logs folder with a password.

  • Influence Maps for Pathfinding?

    - by james
    I'm taking the plunge and am getting into game dev, it's been going well but I've got stuck on a problem. I have a maze that is 100x100 with 0,1 to indicate if its a path or a wall. Within the maze I have 300 or so enemies and a player. The outcome I'm looking for is all the enemies work their way towards the player position. Originally I did this using an A* path finding algorithm but with 300 enemies it was taking forever to path find each one individually. After some research I found that an influence map / collaborative diffusion would be the best way to go. But I'm having a real hard time working out how this is actually done. Firstly.. How do you create a influence map? From what I understand each of my walls with have a scent of 0 so that makes them impassable.. then basically a radial effect from my player position to each other cell (So my player starts at 100 and then going outwards from that each other cell will be reduced value) Is that correct? If so,.. How would you do that (Math magic?) My next problem is if that is correct how would my "enemies" stop from getting stuck if they have gone down the wrong way? As say if my player was standing on the otherside of a wall if the enemy is just looking for larger numbers wont it keep getting stuck? I'm doing this in JavaScript so performance is key. Thanks for any help! EDIT: Or if anyones got a better solution? I've been reading about navmeshs, steering pathing, pre calculating all paths on load etc etc

  • I can't get grub menu to show up during boot

    - by wim
    After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

  • fwupd to update OCZ RevoDrive firmware gets a 'Permission denied' error

    - by Late
    Try as I might I just don't get it working (http://www.ocztechnology.com/ssd_tools/OCZ_RevoDrive_and_RevoDrive_X2/). There's another thread here with an similar issue here: Command is giving me "bash: ./fwupd: cannot execute binary file" I'm running command ./fwupd /dev/sdb which keeps returning me bash: ./fwupd: Permission denied I have tried running both bit versions available of fwupd with both of the latest 32- and 64-bit Ubunty 11.10, running the OS from an USB stick, but to no avail (could this be the problem?). In the other thread it was suggested that chmod +x fwupd (or chmod 0755 fwupd) should resolve this issue, but at least for me it has been for naught. It was also suggested to install certain libraries, but those were already included in the Ubunty build and I didn't have any luck after updating with apt-get. I also tried giving fwupd more privileges, r, x and w but same charade, run it in different ways from different places (where I'd have the fwupd present, ofc) among other things. What I also tried is giving the Ubunty 10.04 LTS a shot but it didn't even launch on either of my computers, though that's not the issue here. If anyone has any ideas on what the problem is and how I could get this working, it would be most appreciated!

  • Resource Acquisition is Initialization in C#

    - by codeWithoutFear
    Resource Acquisition Is Initialization (RAII) is a pattern I grew to love when working in C++.  It is perfectly suited for resource management such as matching all those pesky new's and delete's.  One of my goals was to limit the explicit deallocation statements I had to write.  Often these statements became victims of run-time control flow changes (i.e. exceptions, unhappy path) or development-time code refactoring. The beauty of RAII is realized by tying your resource creation (acquisition) to the construction (initialization) of a class instance.  Then bind the resource deallocation to the destruction of that instance.  That is well and good in a language with strong destructor semantics like C++, but languages like C# that run on garbage-collecting runtimes don't provide the same instance lifetime guarantees. Here is a class and sample that combines a few features of C# to provide an RAII-like solution: using System; namespace RAII { public class DisposableDelegate : IDisposable { private Action dispose; public DisposableDelegate(Action dispose) { if (dispose == null) { throw new ArgumentNullException("dispose"); } this.dispose = dispose; } public void Dispose() { if (this.dispose != null) { Action d = this.dispose; this.dispose = null; d(); } } } class Program { static void Main(string[] args) { Console.Out.WriteLine("Some resource allocated here."); using (new DisposableDelegate(() => Console.Out.WriteLine("Resource deallocated here."))) { Console.Out.WriteLine("Resource used here."); throw new InvalidOperationException("Test for resource leaks."); } } } } The output of this program is: Some resource allocated here. Resource used here. Unhandled Exception: System.InvalidOperationException: Test for resource leaks. at RAII.Program.Main(String[] args) in c:\Dev\RAII\RAII\Program.cs:line 40 Resource deallocated here. Code without fear! --Don

  • Run Win7 Guest (raw disk) in Ubuntu (which was installed as Dual Boot on existing Win7)

    - by kingdango
    I installed Ubuntu 12.10 on top of Win 7 as a dual boot (awesome!). I'm hoping to use VirtualBox to run my original Win7 instance as a guest OS under Ubuntu. I found this existing question and followed the directions to no avail. I can get the VMDK file created but when I run it I just get a blank black screen with no additional information and Windows never loads. I see no HD activity or anything that would indicate it's loading. I used this command to create the VMDK file: VBoxManager internalcommands createrawvmdk -filename ~/.VirtualBox/Win7Native.vmdk -rawdisk /dev/sda3 It looks like everything was created correctly but I just get a blank screen when I run the VM. I do get this warning when I boot the VM: VirtualBox - Warning The virtual machine execution may run into and error condition as described below... The medium '/home/XXX/.VirtualBox/Win7Native.vmdk' has a logical size of 583GB but the file system the medium is located on can only handle up to 16GB in theory. We strongly recommend to put all your virtual disk images and the snapshot folder on a proper file system (e.g. etc3) with a sufficient size. ErrorId: Fat Partition Detected Severity: Warning How can I get this working?

  • What are some good ways for an intermediate programmer to build skills?

    - by Jordan
    Preface: I work mostly in Python, and Web Dev languages (HTML, CSS, Javascript and Jquery, PHP) I'm proficient at coding but I want to get better. In larger more advanced projects my programming skills break down. The more code there is the more trouble I have fitting all the pieces together. I understand syntax well, and I can catch and correct errors fairly easier. But the more advanced it gets the more I struggle. I believe I have a good understand of the basic and nuts and bolts of programming and I understand what's going on, but when it comes to larger projects, especially ones with heavy math involved my confidence flags and I start making mistakes. It's not that I can't do it, I'm just not used to doing it. Does anyone have any advice for someone who knows programming, but wants to get better? The only tutorials I can really find are beginner basic type stuff. Basically what I'm saying is I want to be confident when I'm tackling advanced projects, but I can't because I have little experience dealing with difficult situations.

  • Multi-screen and Nvidia GT220

    - by Bohors
    Excuse me first for my broken English I have 3 monitors on two Nvidia GT220. Unity 2D works fine after using the proprietary drivers. But no way to use compiz effects. I'm on Ubuntu 11.10 (I also tested for curiosity 12.04 for the same result) I noticed in the "System Settings" / "details" that my graphics card is not recognized (graphics card "unknown") and "View" only returns me my first screen (with the correct resolution) also in unknown. $ lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 220] (rev a2) 05:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 220] (rev a2) xorg.conf : Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" Below "Screen0" Screen 2 "Screen2" RightOf "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "1" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "Acer V243HL" HorizSync 30.0 - 80.0 VertRefresh 55.0 - 75.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor1" VendorName "Unknown" ModelName "LG Electronics L1920P" HorizSync 30.0 - 83.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor2" VendorName "Unknown" ModelName "Acer V243HL" HorizSync 30.0 - 80.0 VertRefresh 55.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GT 220" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GT 220" BusID "PCI:5:0:0" Screen 0 EndSection Section "Device" Identifier "Device2" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GT 220" BusID "PCI:5:0:0" Screen 1 EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "metamodes" "1920x1080_60_0 +0+0; nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "CRT: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen2" Device "Device2" Monitor "Monitor2" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "DFP: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Extensions" Option "Composite" "Disable" EndSection Have you any idea? thanks
