At the login screen of my Ubuntu box, I select Ubuntu under the cog menu, but it loads the 2D version instead of the 3D version.

I'm running:

  • Asus P5Q Pro
  • Intel Core 2 Quad Q6600 @ 2.40GHz x4
  • GeForce 9600GT (1024MB)
  • 32-bit OS
  • 4x 1GB DDR2 RAM Modules (although BIOS only shows I'm using ~3GB)

Is this setup not capable of running Unity 3D? I understand that it won't install it if it's not supported!

unity_support_test output:

penGL vendor string:   NVIDIA Corporation
OpenGL renderer string: GeForce 9600 GT/PCI/SSE2
OpenGL version string:  3.3.0 NVIDIA 290.10

Not software rendered:    yes
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:       yes

glxinfo output after driver reinstall:

direct rendering: Yes
    GL_NV_path_rendering, GL_NV_pixel_data_range, GL_NV_point_sprite, 

direct rendering: Yes
    GL_NV_path_rendering, GL_NV_pixel_data_range, GL_NV_point_sprite,

  • run this comand and check if your graphics can support unity or not /usr/lib/nux/unity_support_test -p. – sagarchalise Nov 29 '11 at 11:01
  • I get a 'Segmentation fault' when I run that command.... – neildeadman Nov 29 '11 at 11:21
  • What is the output of this: sudo jockey-text --list – heartsmagic Nov 29 '11 at 11:34

    usually the problems occur when openGL support does not work. Please check the output of glxinfo | grep rendering - there should appear "direct rendering: yes" - further you can test opengl-support with glxgears. Then you should see rotating gears. If one of this does not wort, reinstall your graphics driver. I suggest to install the proprietary Nvidia driver as I described here: http://askubuntu.com/questions/80121/525-m-nvidia-grapic-card-is-not-work-in-linux – Michael K Nov 29 '11 at 11:45
  • @heartsmagic output is: kmod:nvidia_current_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_173 - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_173_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_current - nvidia_current (Proprietary, Enabled, Not in use) -- I tried to install nvidia latest driver and now have x server issues! – neildeadman Nov 29 '11 at 12:42
  • You can remove the installed driver and start the X server again. I don't know what was the error but somehow your card could be incompatible with latest drivers. You can try the others maybe. – heartsmagic Nov 29 '11 at 12:55
  • @neildeadman Can you put the glxinfo and all that stuff in your question so it doesn't get buried in the comments? – Jorge Castro Nov 29 '11 at 13:53
  • @neildeadman - so now that you've installed the graphics drivers - does Unity 3D now work? – fossfreedom Nov 29 '11 at 14:12
  • Partially, I get the Unity 3D display but one screen is white! Guess that is a different issue though.... How do I accept an answer for this Q? – neildeadman Nov 29 '11 at 14:13
  • Screen white? If you have an answer, just write what you have done so far, and accept it yourself. – heartsmagic Nov 29 '11 at 14:22
  • I have two screens... The main one loads Unity or does when Compiz is installed, but the other one is pure white. Without compiz, I can move stuff over to it and use it etc (but no panel at top). With compiz the mouse cursor changes to a black X and it is totally unusable! – neildeadman Nov 29 '11 at 14:32
  • Sorry, I am not so exprienced for multple screens. But I think this is a different problem. – heartsmagic Nov 29 '11 at 14:45
  • @neildeadman - your dual screen white problem is a different issue. Create another question for this - add to that question what you have tried using the nvidia-xconfig app to configure dual screens. – fossfreedom Nov 29 '11 at 16:01
  • @MichaelK Please answer this with your tip on re-installing drivers and I will mark it as the answer as that solved the problem! Thanks! – neildeadman Dec 07 '11 at 14:12
