glmark2 and general opengl issues

[ctrauma]

I have been running a Ubuntu 14.04 trusty guest in a Windows 7 host for months with no issues. Recently I ran into a limitation while running Blender where I needed access to glsl because of an export plugin that was trying to call gpu.export_shader() from the Blender python API and was rolling over when it hit GPU_glsl_support() because the function informed blender it was not supported. Looking into it further I realized I was not using 3D acceleration. I switched it on for the VM and gave it some more video memory.

When I fired up blender it was flickering on and off, parts of the UI were missing, and it frequently just locked up forcing me to kill the process. Searching around the web I found a bunch of discussions here as well as in the Ubuntu forums and in the Blender forums.

Solutions were:

make sure 3D acceleration is enabled
have the latest VirtualBox installed and matching guest additions
make sure that glxinfo lists Chromium/Humper as renderer

There was also a host of test releases mentioned here and there that are now old or unavailable and I'm currently running VirtualBox VM 4.3.27 r99022 win.amd64 (Mar 17 2015 19:25:57) which is pretty new. There were lots of posts from people reporting the OpenGL Warnings about strings not found in the mesa table as well as the missing dri extension, but from what I understand from the answers to those posts is that it is normal behavior because of how VirtualBox hooks the OpenGL calls and these warnings are just noise.

So I have everything up to date, everything enabled, and seemingly all settings correct. Not sure what to try next.. Any suggestions?

Below I've put all the data I could gather and attached both the VBox.log and the output from systeminfo from the host..

The preferences screen in Blender is a complete train wreck, not sure what is going on here..

Just curious, why are you not running the Windows version of Blender? It's bound to run better natively than in a virtual machine.

[ctrauma]

Good question, I do actually run Blender w/Ubuntu native on my desktop without a problem, unfortunately my laptop has to run Windows 7 as it's main OS, so I have to suffer with windows for a lot of my work, and run Ubuntu in a VM to actually get things done.

I really only used Blender in this post as an an example because it gave me the most visual example of problems, every other opengl application I run in virtualbox has similar issues, so I just chose Blender as the poster child. I wanted to give more examples than just the glmark2 output.

[loukingjr]

Blender apparently renders correctly with 3D acceleration disabled. Screen is Blender 2.69 but the results are the same.

[ctrauma]

Yea I did notice disabling 3D acceleration solved all of the render problems but caused some exporters to die because gpu.export_shader() is called in the export script and that throws which stops the export dead in it's tracks. I traced the call back to the source and found that GPU_glsl_support() was telling the python API that glsl support was disabled.

[loukingjr]

Now you tell me.
So I installed it for nothing.

hahaha.. thanks for the effort, sometimes I post too much data and some of the trees get lost in the forest
