Once I did this, I now get great performance with VirtualBox in full screen.By Michael Bose How to Install Kali Linux on VirtualBox: Complete Walkthrough Then under bullet 2, select the High-performance NVIDIA processor for VirtualBox. Select the “Program Settings” tab and hit the “Add” button to add the VirtualBox executable. You can also set what graphics processor to use in the Nvidia control panel under “3D Settings” -> “Manage 3D settings”. The trick is to set the graphics card to be used for VirtualBox. I followed this video to tweak Optimuss settings on a per-application basis. Optimus auto-selects between the low-power integrated, Intel graphics card and the fancy-schmancy super accelerated but power-hogging Nvidia card. What I learned was that Nvidias souped up laptop graphics card had something called “Optimus” built in. Thankfully Windows booted in CPU driven graphics mode and saved my butt.Īfter some research, I was lucky enough to stumble on this SuperUser question with a screenshot that looked eerily familiar. I attempted to delete the integrated graphics card, which was pretty stupid. I attempted to delete the Nvidia from device manager and rebooted, hoping it would “reinstall” correctly. As far as I could tell, for some reason the Nvidia that had come with my Sager was not operating. ![]() I thought a return of my laptop to Sager was definitely going to happen. Not the beefy Nvidia 670M I have installed. Right-clicking on the desktop and selecting “screen resolution” and then “Advanced Settings”, I noticed right away that the the graphics adapter was listed as “Intel HD Graphics 4000″. On a whim I wanted to see if anything was awry in the host’s video card settings. Eventually, I stumbled on something suspicious. None of these things helped improve the performance of my VirtualBox. I attempted to search for people with similar problems. I installed a fresh Ubuntu virtual machine and played with the settings. I tried a lot of things to figure out what was going on. Unfortunately, Unity wasn’t happy when I went into full-screen mode. (It turns out 3D acceleration for the guest is meaningless without the guest additions). This plus installing the guest additions got things working pretty well in windowed mode. I also did an update to Ubuntu to bring in all the updates since the 12.04 ISO was released. Enabled 3D acceleration That helped a little, but it still wasnt quite enough. ![]() Maxed out guest’s video memory to 128 MB.Allocated 4 GB of RAM to the Ubuntu guest.Allocated 2 logical cores to the Ubuntu guest. ![]() In my configuration, I made the following change. Luckily I’ve got quite a bit installed on this new laptop, so the host has plenty to be generous with. The first thing that occured to me was to give the guest enough RAM, processors, and video RAM with 3D acceleration to quench its appetite. Optimus is a video card power saving technology that I’ll describe below The intersection of these two new things caused my Ubuntu guest to lurch pretty badly after the initial install. Pretty heavy 3D desktop environment that tends to lurch unless you have the right hardware and right Virtualbox settings I have all the power of Linux and all the device support of Windows, woohoo! And I can easily do Windows dev at the same time, double woohoo! Anywho, a few things have changed since the last time I got this setup working: Mostly cause I’m not trying to force Linux to run on a bunch of hardware it’s probably missing support for. The number of glitches I have to work through tend to be really few compared to a direct Linux install. Traditionally when I need to do Linux dev in this kind of environment, I’ve loaded up Ubuntu in VirtualBox. Since I’m pretty much changing everything about my career, I thought I’d stick to one thing staying the same – I’ll stay with a Windows PC (specifically Win 7 圆4 sp1). So I’ve got a new hooptie laptop (a pimped out Sager NP9170).
