I'm trying to install gentoo from usb. I'm using windows7 I downloaded the amd64 in: iso ( install-cd on this page: https://www.gentoo.org/main/en/where.xml then used Unetbooting to burn it on my usb. For some reason in the choices of distributions gentoo does not appear so I don't select any distribution. It worked before but now when I select the default option after reboot it says the iso is corrupt. I tried on another usb key, tried with lili usb creator, win32diskimage, universal-usb-installer, yumi, sardux64 and none of these work.
You can try just copy byte-to-byte liveDVD iso to you flash drive. Use dd command for this (under Win you can find some analogs).
The good article about Gentoo on USB: https://wiki.gentoo.org/wiki/LiveUSB/HOWTO
I was able to use UNetbootin.
First select the Diskimage radio button. Next push the three dots button to select the iso install-amd64-minimal-20140828.iso. Next select the usb drive and push the ok button.
Your machine should be using legacy bios to boot the usb. On my dell I push F12 on the bios screen for a boot menu and then select usb to start.
Once grub comes up select gentoo to use the usb drive.
The minimal install cd has worked great but any live disk can be used. The live disk is only used to connect to the internet, prepare the disks, copy the stage 3, and chroot into the disks. Most distributions have live disks that can do this.

Installed virt-manager,
target virtual machine is debian jessie with spice-vdagent installed
shared clipboard, and latency-free mouse input works
Display: Spice
Video: QXL
Channel spice: spicevmc, virtio, com.redhat.spice.0 (confirmed /dev devices exist in target vm)
Make sure guest resizing is enabled in virt-manager:
Menu View -> Scale Display ->
Auto resize VM with window (Checked)
Make sure your have a spice agent on your guest (the virtual machine)
https://www.spice-space.org/download.html#guest
'spice-vdagent' on linux
'spice-guest-tools' on windows
How I figured this out,
I found a setting in "spicy" that I assumed had an equivalent in virt-maanger. To connect with spicy from spice-client-gtk apt package, I found the port to connect to by checking sudo ss -nlp | grep qemu, and connected to that port on localhost. Spicy's toggle was much easier to find: Options -> Resize guest to match window size (Checked).
For XFCE, this is a known bug which does not appear to have been fixed yet (confirmed still broken in Xubuntu 20.04).
This issue is due to a change in spice-vdagent whereby instead of changing the resolution directly, it instead notifies the DE to make the change, and that functionality has not been implemented yet in XFCE.
One workaround is to run the following in the guest every time you resize your window:
$ xrandr --output Virtual-1 --auto
According to Installing Windows 10 in KVM + libvirt, visit Spice then scroll down to Windows binaries and then click the link spice guest tools. Proceed to install the spice tools after download completes. Once installation is complete, you should be able to get the guest VM resolution to match that of the resized VM window.
For me, "Auto resize VM with window" was greyed out until I installed the spice guest tools; I did not even have to reboot after installation - this feature was available immediately and it just worked - :).
Host machine: Ubuntu 16.04.6 LTS (Xenial Xerus)
Guest VM: Windows 10 Pro (Version 1809 build 17763.379)
#ThorSummoner's approach works, but if you have a high resolution monitor, the guest video driver may not have enough memory to draw the larger screen. In that case, you will need to increase the video memory, but unfortunately the virt-manager GUI doesn't provide a method to do so. So instead follow this procedure:
View -> Details -> copy the UUID.
sudo virsh edit <copied uuid>
Look for a line like the following: <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/>. Your type and other parameters may be different, but as long as there's a vgamem, you can continue.
Change vgamem to 32768
Save & exit. The config file will automatically be checked for errors.
Then restart your VM, and try again.
Short answer that worked for me:
I also have Display set to Spice. If the VM's virtual Video hardware was set to VGA or QXL, I could not resize the desktop in the guest. When I changed Video to Virtio in virt-manager and restarted the VM, it worked.
Longer background in case it's useful to future visitors:
I ran into this problem in May 2020 and while the older answers here were of some help I thought I'd add some clarifications since the virt-manager UI and libvirt capabilities continuously evolve.
In my case, I have a Fedora 32 (KDE Spin) Linux host and the same OS in the guest. My virt-manager version is 2.2.1.
As with thorsummoner's original situation above I am using Display Spice so I can have goodies like the shared clipboard between host and guest.
The guest seemed stuck on 1024x768. xrandr in the guest showed lots of higher resolutions available, but when I tried to set the resolution to 1920x1080 -- whether with xrandr --output Virtual-1 --mode 1920x1080 or with Plasma's Display setting -- it would only momentarily change to the higher resolution. Then, clunk, it would change right back.
Explicitly setting a higher level VGA video memory did not work (although it did help for another problem long ago).
No matter what I set virt-manager's View -> Scale to display menu options to, this still happened.
The fix for me was in the virtual hardware Video settings. Note: not Display, but a separate entry further down in the left-hand-side Hardware list in virt-manager.
If video was set to VGA or QXL, I could not resize the guest.
Then I changed the video hardware to Virtio, and the problem went away. I could resize the desktop with either xrandr commands or the GUI Display preferences, and the changes would stick even after restarts.
Of course the guest VM should be cleanly shut down before making this change to its virtual hardware settings.
What worked for me is much simplified modified ThorSummoner's answer:
Step 1:
View > Scale Display > Always
Step 2:
View > Scale Display > Auto Resize VM with window
Step 3:
In the guest OS, set the desired resolution.
I tried everything I saw to make it work but the only thing that worked for me was to set video to QXL (didn't tried Virtio or VGA after that tho) and do a proper shutdown of the Windows 10 VM (from inside the VM, do a "shutdown"). If you use the reboot from virt-manager it seem's like it doesn't reboot entirely.
What worked for me (finally!):
Debian 11.6 on my host laptop.
Debian unstable as my guest VM.
In the guest, "apt install spice-vdagent".
In the guest details (View / Details):
Display Spice = Spice Server
Video = QXL
View / Scale Display = Always
When logged into KDE Plasma (X11) as my Desktop Environment, the View / Scale Display had the "Auto-resize window with VM" option selected, but it was grayed out and KDE's resolution would not resize as I changed the guest window size; it would scale to some degree, but it seemed to be using a magnification effect rather than actually changing the resolution.
When logged into Cinnamon or into Gnome (just plain "Gnome", not "Gnome Wayland" or "Gnome on Xorg" or any of the other Gnome options in my selection pull-down menu), the View / Scale / Auto-resize was not grayed out, and both DE's resized as I resized the guest window.
Note: the resizing was not instantaneous; it took a second or two after I finished resizing the guest window before the DE changed resolution to match.
In my case, I had manually set resolution to 1920x1080 prior to booting with SPICE vdagent. I just had to go to settings, display (will depend slightly between DE), and select the resolution corresponding to SPICE resize mode.
For those of you who still haven't got virt to auto-resize with suggested config (spice channel, spice guest tool, QXL), this is how I solved mine.
Background: I got it to auto resized before, but I got a clean install of ubuntu, and using the same config, same vm files (was actually physical partition), but I can't get it to resize again. I got spice channel in the config with QXL video, spice guest tools in windows guest, but still can get it to resize.
So finally, I just got a clean install of both windows and my distro (this is not the solution, just indicating that my config was clean). I tried again with the same config but nothing work, and I started to wonder if windows I the problem here, which it ultimately was. I checked the device manager to see that 2 virtio drivers were rejected by windows secure boot. So as an instinct I went in tiano bios (ovmf) and disable secure boot. It's working fine now.
Form me it was just a matter of going to the VM click Show virtual hardware details icon, resize that window, then click back on the Show the graphical window icon since they share the same window.
Resizing on Windows guest works if you install the virtio display driver.
Open "Device Manager", right click on "Display adapters", right click on the one entry you find, then "Update driver", browse for a driver, select the virtio ISO, and install the driver.
Notice the entry won't be displayed with a yellow warning sign, as Windows will use the Microsoft Basic Display Adapter drivers, and so it is all fine for it.
I have virtualbox running an Os X 10.11 El Capitan VM and I want to be able to boot my computer into OS X, but I can't figure out how to create a usb that my computer will successfully boot to or try to install mac to install to a partition. I've tried transmac and much googling. I was wondering if there is a way to use my existing .vdmk file to boot to a partition on my computer or if there is another solution.
I have heard about two possible solutions (but I never try them):
First - you can try convert your .vdmk file into an iso image, and then boot to a partition on your computer.
Second - you can try clone your .vdmk file using Clonezilla (http://clonezilla.org/) and then boot from It.
Hope it works for you.
Ever since I have upgraded my laptop (Click here for hardware specs.) my screen usually freezes. Mostly in chrome or Firefox browser. I am pretty sure this is a Nvidia driver problem but I can't seem to find the solution. I am running a Nvidia Quadro K2100M.
I am currently running Nvidia 361.42. I have tried using open source Xorg server without any luck.
The only solution I have found so far is forcefully turning off the computer by holding down the power button.
Things that I have tried:
I got keyboard input
I cannot switch to another terminal to restart lightdm
This problem came to me occasionally, making me really annoyed.
As illustrated in many blogs, this may be caused by graphic driver problem. For me, my desktop has a NVIDIA video card, you can run lspci | grep VGA to see what type of your video type, in my case, it returned:
02:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400 GS Rev. 2] (rev a1)
I followed the instruction on jiakai zhang's blog to reinstall proper drivers for the desktop, hope this will help you.
The key steps in [1] are to reinstall the ubuntu desktop and nvidia drivier by:
$ sudo su
$ apt-get update
$ apt-get install --reinstall ubuntu-desktop
$ apt-get install unity
$ apt-get remove --purge nvidia*
$ reboot
$ sudo apt-get install nvidia-current
$ sudo reboot
Updating the grub settings worked for me! Do the following:
1. Open the GRUB configuration
sudo vi /etc/default/grub
2. Change the value of GRUB_CMDLINE_LINUX_DEFAULT from "quiet splash" to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"
and save the file.
3. Update & Reboot
sudo update-grub
sudo reboot
More info:
This is a bug in the processor, known as the c-state bug. It causes total freezes when the CPU tries to enter an unsupported sleep state. It's a problem for many Bay Trail devices especially with newer (4.*) kernels. There is a simple workaround until it gets properly fixed upstream. You just need to pass a kernel boot parameter and the random freezing stops completely. The parameter may increase battery consumption slightly, but it will give you a usable system. You do this by editing the configuration file for GRUB as described above.
GRUB - boot loader package from the GNU Project, which provides a user the choice to boot one of multiple operating systems
installed on a computer or select a specific kernel configuration available on a particular operating system's partitions;
Intel Bay Trail - new Atom Processors from Intel. Atom is Intel's family of x86 and x86-64 processors that are optimized
for small computing devices, such as smartphones and mobile Internet devices;
C-States - used to optimize optimize or reduce power consumption in idle mode (i. e. when no code is executed) - (C0 to C8)
Reference: here.
I have since fixed this problem by re-installing Ubuntu 16.04 and not switching from the nouveau video driver. I also disable updates and everything been working good for about 2 months now.
Gaming is pretty good but I usually play steam games so doesn't push any kinda hard core graphics
Well, I had the same problem: My PC was freezing randomly. I tried Ubuntu 16, 17 and 18.04 and everything was the same. I tried several drivers and didn't get a solution. I tried several solutions that I found in the forums (including this) and got bad and harmful results.
My solution was: I stopped using the graphical nvidia card, removed it and now I'm using the integrated Intel HD graphics card (Intel® HD Graphics 530 card (Skylake GT2)) and all the problems were solved!
I fixed mine using a few commands from #Qoros solution above. i just ran apt-get update, apt-get install nvidia-current, and sudo reboot. cheers to #Qoros btw!
For me, none of the approaches described in rest of the answers worked.
I was opening multiple terminal tabs running some heavy processes and ubuntu used to freeze when I had 6-7 tabs. I tried monitoring the resources used while I was starting my processes in terminal tabs. You can do it by opening System Monitor app and going to Resources tab.
What I noticed is that when my RAM(8GB) and my swap space(1GB) were completely used up, ubuntu would freeze.
As a solution, I increased my swap space and made it 16GB. After this memory never gets used completely and ubuntu doesn't freeze.

Could anyone get the camera data from the Kinect using a Raspberry Pi ?
We would like to make a wireless Kinect connecting it using Ethernet or WiFi. Otherwise, let me know if you have a working alternative.
To answer your question, yes it is possible to get Image and depth on the raspberry pi!
Here is how to.
If you want to use just video (color, not depth) there is already a driver in the kernel! You can load it like this:
modprobe videodev
modprobe gspca_main
modprobe gspca_kinect
You get a new /dev/videoX and can use it like any other webcam!
If you need depth (which is why you want a kinect), but have a kernel older than 3.17, you need another driver that can be found here: https://github.com/xxorde/librekinect. If you have 3.17 or newer, then librekinect functionality is enabled by toggling the gspca_kinect module's command-line depth_mode flag:
modprobe gspca_kinect depth_mode=1
Both work well on the current Raspbian.
If you can manage to plug your kinect camera to the raspberry Pi, install guvcview first to see if it does works.
sudo apt-get install guvcview
Then, typeguvcview in the terminal and it should open an option panel and the camera control view. If all of that does works and that you want to get the RAW data to do some image treatments, you will need to compile OpenCV (it takes 4 hour of compiling) and after that, you just will need to program whatever you want. To compile it, just search on Google, there are lots of tutorial.
Well, as far as I know there are no successful stories about getting images from Kinect on RaspberryPi.
On github there is an issue in libfreenect repository about such problem. In this comment user zarvox say that RPi haven't enough power to handle data from Kinect.
Personally I tried to connect Kinect with RPi using OpenNI2 and Sensor, but have no success. And that was not a clever decision because it's impossible to work with Microsoft Kinect on Linux using OpenNI2 due to licensing restrictions (Well, actually it is not so impossible. You can use OpenNI2-FreenectDriver + OpenNI2 on Linux to hookup Kinect. But anyway this workaround is not suitable for RaspberryPi, because OpenNI2-FreenectDriver uses libfreenect).
But anyway there are some good tutorials about how to connect ASUS Xtion Live Pro to RaspberryPi: one, two. And how to connect Kinect to more powerfull arm-based CubieBoard2: three.
If you intend to do robotics the simplest thing is to use the Kinect library on ROS Here
Oderwise you can try OpenKinect, They provide the libfreenect library that let you acess to the accelerometers the image & much more
OpenKinect on Github here
OpenKinect Wiki here
Here is a good exemple with code & all the details you need to connect to the Kinect & operate the motors using libfreenect.
You will need a powered USB hub to power the Kinect & to install libusb.
A second possiblity is to use the OpenNI library which provides a SDK to develop midleware libraries to interface to your application there is even an OpenNi lib for processing here.
yes, you can use Kinect with raspberry pi in a small robotic project.
I have done this work with the openkinect library.
my experience is you should check your raspberry pi and monitoring pi voltage, not time does to low voltage.
you should accuracy your coding to use lower processing and run your code faster.
because if your code had got a problem, your image processing would be the slower response to the objects.
https://github.com/OpenKinect/libfreenect https://github.com/OpenKinect/libfreenect/blob/master/wrappers/python/demo_cv2_threshold.py
This programming guide implies that this is possible, so I figure what the heck.
Right now, though, it doesn't work.
Host OS is Vista 64-bit, VMWare Workstation 6.5.3 is running Windows 7 Enterprise 32-bit.
Installed Software on the VM:
Visual C# 2010 Express
Microsoft Server Speech Platform Runtime
Microsoft Server Speech Recognition Language - Kinect
Microsoft Speech Platform SDK
Kinect for Windows SDK Beta
I plug in the Kinect, the device is recognized by the VM, then I run the Sample Shape Game and it doesn't recognize the device. It says "Plug in the Kinect and try again" which turns out to be error 0x80080014, which leads to
http://social.msdn.microsoft.com/Forums/en-US/kinectsdknuiapi/thread/4da8c75e-9aad-4dc3-bd83-d77ab4cd2f82/
which gives me two things to look at:
is it plugged in with the special cable? yes
are all 4 entries in the Device Manager? no
In the Device Manager, I see a "Microsoft Kinect" group containing Microsoft Kinect Audio Control, Microsoft Kinect Camera and Microsoft Kinect Device, but there is nothing under "Sound, video and game controllers" other than VMware VMaudio. "Kinect USB Audio" should be there.
I'm guessing that there is some further twiddling I have to do with the VMWare USB / hardware options (whatever that tray with the USB / CD / HD / floppy etc icons is called) or some deft combination of rebooting and (un)plugging, but I'm almost out of enthusiasm.
Any ideas? TIA
EDIT: I realized that I had some lingering drivers on my host (Vista) system from OpenKinect. After removing them, I can no longer see the Kinect at all in the VM. Hmm.
There is this on read.me
Virtual machines: You must run applications built with the Kinect for Windows SDK Beta in a native Windows environment. Kinect for Windows applications cannot run in a virtual machine, because the Microsoft Kinect drivers and this SDK Beta must be installed on the computer where the application is running.
just to share that (not really understood how) VM Workstation 8 running in a host win 7 x64 with guest OS Ubuntu 10.04 sucessfully detected and installed Kinect drivers.
I was able to test it with libfreenect (OpenKinect Project) http://openkinect.org/wiki/Getting_Started#Manual_Build_on_Linux
best regards,
I'm late to the party, but we've been running and developing for the Kinect with Windows 7 running under VMWare under Mac OS X Mountain Lion.
I'm not a Computer Scientist, but I thought Turing showed that a universal Touring Machine was basically the same as physical hardware. I've had Distributed COM+ running on 3 or 4 VM's on the same physical hardware, but somehow the Kinect device is different? I don't buy that at all.
The most recent version of Microsoft Kinect for Windows (v1.6, possibly slightly earlier versions) in combination with the "Kinect for Windows" hardware does work inside a virtual machine. I run this setup on a MacBook Pro, Parallels 7 and Windows 7.
Note that a Kinect for Xbox does not work inside a virtual machine.
This page from Microsoft says that the "Kinect for Windows" device should work in a VM, but that the "Kinect for XBOX" does NOT work.
First of all you just need two Things to be installed:
libfreenect
libusb
after that you should set three flags to 0x02 at the line
typedef enum {FREENECT_DEVICE_MOTOR = 0x02,FREENECT_DEVICE_CAMERA = 0x02,FREENECT_DEVICE_AUDIO = 0x02,} freenect_device_flags;
Inside the headerfile located at /usr/local/include/libfreenect libfreenect.h but you will lose the ability to control the movement and the the microphone usage will be disabled so don't even try to access them or your device might get damaged after that you should also set
#define PKTS_PER_XFER 32
#define NUM_XFERS 6
inside your libfreenect/src/usb_libusb10.h file at the linux Line
After that rebuild your libfreenect by
mkdir build
cd build cmake ..
make make install.
Than Restart your virtual System and plug and connect only the Kinect Camera Device and no other Kinect device during start of the VM. When System is up you could test your device is properly working by switching to your previously created libfreenect build directory and go to bin there you run ./freenect-camtest you should get no or only a small number of package losses if a lot of losses occur try restart your vm with the camera device pluged in and already connected to your vm. You might need to active disconnect and connect the Webcam from the VM during startup to receive images this should be done during first seconds of VM Boottime!
Works with Ubuntu 14.04 and Workstation 10 and 11 and 11.1
HOST OS Windows 7 and Kinect SDK installed and Kinectdevice for Windows
Also it seems to be quite unstable you often have to restart your virtual system if you can't receive images from your Kinect. But if you once received images don't unplug device or you won't get data until you reboot virtual system with Kinect Camera connected to it.
=> This actually solved the problem otherwise to much frames get lost and its not possible to display proper image!
