Slow performance of Ubuntu Guest VM on VirtualBox
Source: http://askubuntu.com/questions/284551/performance-problems-with-13-04-and-virtualbox
Graphic/performance fix for Ubuntu was tested with Ubuntu 13.04, 12.10, and 12.04. Part of this solution applies where aero / transperancy is used including d3d games.
RAM requirements
Recommended graphic memory or virtual ram for aero based operating systems is 256 MB min.ram -768 MB for 13.04
Virtual machine settings
-
enable 3d support in virtualbox 3d settings
-
terminal commands:
/usr/lib/nux/unity_support_test -p
(Not software rendered:no, unity 3d support:No)
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 follow
cd /media ls cd username ls cd VBOX* ls sudo ./VBoxLinuxAdditions.run sudo gedit /etc/modules
add “vboxvideo” in the next line after lp means
loop>lp>vboxvideo
like this click save and file quit -
restart the machine
-
now open the terminal to checkunity 3d is enabled or not
/usr/lib/nux/unity_support_test -p
-
after this shut down the machine lets increase the virtual ram
-
close virtual machine and virtual box
-
follow this path
C:\Users\Username\VirtualBox VMs\ubuntu 13.04
-
now look for “.vbox” extension file and open it with temporarily with wordpad
-
look for the following lines and replace these in following manner
Display VRAMSize="128" monitorCount="1" accelerate3D="true" accelerate2DVideo="false"/>
to
Display VRAMSize="256" monitorCount="1" accelerate3D="true" accelerate2DVideo="false"/>
-
now you can set 256 mb virtual memory for this operating system.
-
any OS can be provided with desired vram this way
