How to fix slow performance ubuntu 13.04 running in virtualbox

Having very slow perform when running Ubuntu 12.10 and 13.04 in virtualbox? It’s because Ubuntu can’t use graphics card for acceleration, ubuntu uses CPU for rendering graphics trough LLVMpipe. It makes running ubuntu in virualbox really slow.

To check if your Ubuntu 12.10 guest is using 3D acceleration

/usr/lib/nux/unity_support_test -p

You should see something like this

Not software rendered: no
Not blacklisted: yes
GLX fbconfig: yes
GLX texture from pixmap: yes
GL npot or rect textures: yes
GL vertex program: yes
GL fragment program: yes
GL vertex buffer object: yes
GL framebuffer object: yes
GL version is 1.4+: yes
Unity 3D supported: no

If you see “Not software rendered” and “Unity 3D supported” both say no. This means Unity is using slow LLVMpipe.

To enable 3D supported, fist you will need to update linux-headers

uname -r
sudo apt-get install linux-headers-$(uname -r)
sudo apt-get autoremove
sudo apt-get install build-essential

Now insert vitualbox guest iso from devices and to install manually

cd /media
ls
cd username
ls
cd VBOX*
ls
sudo ./VBoxLinuxAdditions.run

Insert vboxvideo to /etc/modules

sudo nano /etc/modules

Add “vboxvideo” at the end of the file

loop
lp
vboxvideo

Reboot the machine

sudo reboot

Check ”Not software rendered” and “Unity 3D supported” are enabled or not after rebooting

/usr/lib/nux/unity_support_test -p

The next thing you want to do is to increase video memory. Look for .vbox file

nano /home/username/VirtualBox VMs/ubuntu/ubuntu.vbox
