Ubuntu 14.04.1 running slowly on Windows 8.1

[MartinMihov]

Hello,

First I would like to appologize for the really common topic, but it is a fact. I've been trying to get the new Ubuntu work fine on my laptop, but I couldn't succeed. So here is all the info about my system:

1. Host:
Processor Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz
RAM: 8.00GB
Graphics card: NVidia GeForce GT 635M 2GB
OS: Windows 8.1 Pro 64 bit
VirtualBox version: 4.3.16 r95972

2. Guest:
Ubuntu 14.04.1 64 bit
RAM: 2GB
Processors: 1CPU
Video memory: 128MB
3D Acceleration enabled
Guest Additions installed.

I have also attached the VirtualBox log file for more info on my setup.
So the problem is basically that the Ubuntu VM is really slow. Moving windows around is not smooth at all, changing workspaces takes some time and switching between windows too, which makes it somewhat annoying to work with. I have tried loads of suggestions on various forums and blogs, including reinstalling, reducing RAM, increasing RAM, reducing/increasing CPUs, enabling/disabling 3D acceleration, changing the chipset, installing custom guest additions and so on... What I have found out is that:

Code: Select all

/usr/lib/nux/unity_support_test -p

gives me:

Code: Select all

OpenGL vendor string:   VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits)
OpenGL version string:  2.1 Mesa 10.1.3

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

and as far as I understood, the two "no"s could be the problem.

Also in the past week I've seen VirtualBox running a guest Ubuntu 14.04.1 both on Mac and Windows 8.1 hosts, but with less powerful hosts, running the VM a lot smoother than mine. If anyone could help me fix this problem, I would be really greatful.

Enable 3D acceleration in the guests settings and then run the following in the guests terminal and post the results

Code: Select all

glxinfo | grep OpenGL

Enabled 3D acceleration and tried to run the command. It said that mesa-utils was not installed, so I installed them and ran the command. Here is what I got:

Code: Select all

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits)
OpenGL version string: 2.1 Mesa 10.1.3
OpenGL shading language version string: 1.30

It still is not using the hosts graphics accelerator. When it does you will see chromium and humper instead of VMware and Gallium.

It may have to do with specific drivers in VBox and the new code. You have two options which are revert to version 4.3.12 or post a ticket at bugtracker. I believe ther eis already a ticket about this and you need to search and attach your information to that ticket. There may even be a test build that addresses this too.
