I have an old system with NVIDIA Corporation NV25 [GeForce4 Ti 4600]. When running Ubuntu , the nouveau driver loads fine but does not log into Unity with compiz. Instead it logs into Unity-2D. Any idea how to enable 3D/ compiz with the nouveau driver.
OS: Ubuntu 12.04 Beta2
The nvidia driver is no more available for this graphics card, so have to rely on nouveau.
UPDATE: Bug reported on launchpad . See here.
There has been no reply as yet to this bug-report - does anyone have any idea how to resolve this?
Also, if I use kubuntu desktop, kwin graphics works just fine. But, the users prefer Unity over KDE so I have uninstalled Kubuntu.
libgl1-mesa-dri-experimental does not have any effect on the installation. still booting to unity-2d
