Comment 164 for bug 982485

Mine is working again. I have Nvidia Geforce Go 6150 integrated graphics inside a Compaq Presario V3000.
When -proposed was released, I first uninstalled nvidia-current and installed nvidia-current-update (295.49) from -proposed. It worked fine. So, when the nvidia-current 295.49 driver was finally released, I uninstalled nvidia-current-update and reinstalled nvidia-current, not without running apt-get update first.

For those who are still having unity2D being loaded, I know it may sound silly but... have you checked if Unity3D is selected as the main session? I've done this mistake a thousand times myself, checking unity2D whenever I had a problem with 3D and always forgetting to change it back when a fix was released.
