I am trying to figure out why Ubuntu and Linux Mint only run in Software Rendering Mode on Virtualbox. My motherboard supports hardware virtualization and it is turned on, and I have installed the Guest Additions succesfully. Both OSs are extremely sluggish.

I am running an MSI GS70 laptop with a Core i7 processor and a GTX 765M gpu with optimus.

I have turned on 3d acceleration, given the maximum GPU allowance, updated my GPU driver to 326.80, installed guest additions. All of these things helped slightly but have not solved the problem, Linux Mint is still showing that I am running in software rendering mode only.

Anything I can try, or questions I should be asking?

To fix:
shut down the Linux Mint VM.
Edit the VM settings in VirtualBox.
Click "Display -> Enable 3D Acceleration"

As stated in my post, I have been using 3D acceleration. – Ty Underwood Sep 18 '13 at 18:57
This worked for me, thanks! – Richard-dW Jul 11 '14 at 7:24
Doesn't work for me in VMWare when I enable the equivalent setting. – Sridhar-Sarnobat Aug 24 '14 at 19:09
Thanks, Worked for me too. :) – Udhay Apr 17 '15 at 15:25

This seems to be an issue with VirtualBox Guest Additions 4.3.8-4.3.12. It seems that 4.3.13 fixes the issue. , though I cannot find an available pre-RC ISO any longer.


Update: I was able to bypass the issue using 4.3.10 that is packaged with Linux Mint 17 by avoiding the untested updates which contained several updates to mesa and opengl. I had no issues by sticking to the security updates until 4.3.13 is officially released.

Have you tried installing another desktop environment? I have seen problems with Cinnamon (for Mint) on both VirtualBox and Hyper-V (e.g., here).
