I am trying to run a program via Ubuntu 16.04 as a Virtualbox VM.
The binary of this program checks if it's running on a virtual machine, and does something different on a VM than if it is on a given computer.
How can I know what the binary is querying? Can I use something like strace or ldd for this?
I would like to be able to run the binary as if it was on a real machine, not a VM. I presume there must be a way to change what's reported by the Ubuntu 16.04 when the binary queries it.
How can I disable the Keyboard Shortcut ctrl+shift+c in Google Chrome to bring up the Developer Tools console?
I find myself trying to copy+paste content from the browser and mistakenly typing ctrl+shift+c when I really want to do ctrl+c instead.
How can I disable the current keyboard binding or change ctrl+shift+c to do the same as ctrl+c in Google Chrome?
My Ubuntu 12.04.1 running on virtualbox ran out of space while I was installing software on it and now it is not rebooting. I've got files I need to recover from it. I have the ubuntu64.vdi file on my Windows 7 (host) laptop and I was wondering if there is any way of recovering the files from the vdi file.
In parallel, I generated a fresh 12.04.1 machine on virtualbox in the same laptop, and I'll use that one instead of the borked one.
I can add the borked vdi to the list of disks in the working one. Then I used gnome nautilus to mount the borked disk.
I can find the files in there, but they are about 2 months old. I think this coincides with the last time that I did a virtualbox snapshot of the machine, but not the last time I got a working machine, which was yesterday. Is there any way of mounting the vdi as of yesterday, just before it crashed?
EDITED:
Here is what Virtual Media Manager tells me about my ubuntu64.vdi file:
EDITED2:
I copied my ubuntu.vdi to an external USB with plenty of disk space. I tried using Windows to clone it, but got an error:
I tried the same from the working VM via a shared folder of the USB drive, and it started the cloning. Took a good while, but finished successfully:

I downloaded firefox 19 and executed it on my Ubuntu 12.04 machine. I went to a website with pdf links, clicked on one of them, hoping to have it shown in the built-in pdf viewer in Firefox 19, but only got the common pop-up menu with the options of viewing it with Evince or downloading it to a folder. How can I use Firefox 19 built-in pdf viewer?
What is the best way to start a Steam game on a NVIDIA Optimus laptop with Ubuntu 12.04 installed and the latest version of bumblebee installed?
If I call Steam with optirun steam and then choose the game I want to play, I get the following error:
The program 'hl2_linux' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
(Details: serial 125 error_code 9 request_code 14 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

If I run steam without the optirun option, I can go a little further into running the game, hearing the starting music on a black screen, but still fails later on in the process.
Should I call the game I want to play with a special optirun command instead of optirun steam?
I have seen that I can control the speed of vlc by using the keyboard shortcuts +/-. It works to play the movie slower with [-], but I can't get it to play faster than 1.00x with the [+] keyboard shortcut. This is with vlc run as cvlc file.mkv version 2.0.3-0ubuntu0 under Ubuntu 12.04 x86.
I am doing this on a laptop, so the only '+' sign I have is in the [+/=] key.
Any ideas?
I have been trying an Android Virtual Machine called androVM on an Ubuntu 12.04 32 bit laptop with Intel/Nvidia hybrid graphics configuration as the guest OS (details on the graphic cards below). I tested some of the graphics-intense applications, like Angry Birds, and AnTuTu, a benchmarking application, running virtualbox and AndroVMplayer with primusrun, but they seem really slow, no difference whatsoever as when run without primusrun. I have also tried optirun, which simply crashes with a segfault. How can I enable OpenGL acceleration for this VM in my hybrid graphics system?
The AndroVM version I am running is this one:
androVM_vbox86tp_4.1.1_r6.1-20130222-gapps-houdini-flash.ova
And I am following the installation instructions as explained here:
AndroVM 20130222 release | AndroVM blog
Under Virtualbox, I have the switched Graphics options set to 128MB Video Memory and Enabled 3D Acceleration and 2D Acceleration. My host BIOS has its virtualisation options activated. Here are my hardware details:

My newly installed Ubuntu 12.04 gnome-classic just turned into chinese locale after reboot, how do I change it back to English?
I can't find any language menus, and the ones I opened are, well, in chinese...
When I open a terminal and execute gnome-language-selector, I get lots of this in the prompt:
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
Any ideas?
If I go to the Language section in Users, I only get the options in the picture.
I've got a script that is executed in order to have suspending/resuming working in my laptop. Then I have another series of xinput,xkbset and xmodmap commands that are executed when I initiate a session to have two-finger scrolling and keyboard shortcuts set up. When I resume from suspend, two-finger scrolling and my keyboard shortcuts won't work. I need to manually execute the commands in the second file again. How can I add those to the suspend/resume script to have this done automatically? See below:

Is there an easy way to to that?
I've got an Ubuntu 11.10 system connected via a proxy to the internet, and I would like to install packages via apt-get. When I try to do that I get this error message:

I would like to specify that when I press the power button in my laptop, a 'shutdown -h now' command is sent, instead of bringing up the graphical shutdown menu. How can I do that on Ubuntu 11.10?
What is the difference between the shutdown menu item and shutdown -h now?
The former sometimes hangs up my laptop on Ubuntu 11.10.
I would like to use ffmpeg to transform an mp4 video file into avi but with the same quality, even if it takes up more space. If I simply do:
ffmpeg -i file.mp4 file.mp4.avi
The resulting avi file is very low-quality and pixelated. How can I do this transformation while keeping the video and audio quality?
In Ubuntu 11.10, how can I set up nautilus so that when I select "Save as..." on Evince or some other PDF viewer, for a PDF I downloaded with the browser, it automatically suggests the folder 'Documents' for saving that pdf file?
Right now it just gives me the last folder that was used to save something before. I remember 11.04 was doing exactly this, which is convenient to keep all pdfs in a single folder.

Has anybody got any idea what would be needed to have a working external GPU system (eGPU) under Linux? I've just seen this post of a DIY eGPU system:
I found this mentioned which I think is also relevant:
My system has switchable graphics. Can I still do a eGPU?
Yes you can. Setup 1.x's (Video card->Hybrid Graphics.dedicated=off) allows the dedicated graphics component to be completely disabled on Series-5 or older chipsets, freeing up 32-bit resources to host the desktop eGPU. If your primary video card is a Intel 4500MHD, HD or HD3000 then can even do a x1.Opt NVIDIA setup.
I use gnome-display-properties to configure the external screens that I attach to my laptop at home and in the office. Gnome-display-properties cleverly remembers which screen is which, and automatically sets the display up when the screen is plugged.
For example, in gnome-display-properties, the monitor shows as "Monitor: Samsung Electric Company 24''", I wonder where is this info pulled from?
Where is this information saved?
I sometimes have an rtkit-daemon process eating 100% of my CPU and making the system unresponsive. I reboot and things are fine after that. What is rtkit-daemon supposed to do and why would it be sometimes eating up 100% of my CPU?
