Grphics acceleration is disabled in Ubuntu. I went to Software & Updates and opened the Additional Drivers tab and was presented with a list of drivers, which one am I supposed to install?

Why is the correct driver not automatically selected and enabled during installation? This is really not user friendly, I can't even play a simple WebGL game (such as apathy.plankhead.com) because it needs 3D acceleration.

Update:

I installed the "tested" nvidia drivers as per lupp0l0's recommendation and restarted my computer. Startup failed with a screen that said "nvidia: module license 'NVIDIA' taints kernel.".

After rebooting a few times, Ubuntu finally started. I'm worried that next time I restart Ubuntu will fail to load again.

Please, let us know which drivers you see from the "Additional Drivers" tab. –  lupp0l0 Apr 26 '13 at 8:03
    
Sorry, i have a nvidia card so i can see nvidia-310, nvidia-310-updates, nouveau (currently selected) and some beta/legacy drivers. –  OpenTangent Apr 26 '13 at 8:08
    
Just as a quick note, WebGL does not always work, even if you do have the additional drivers. Blame the web browsers for that ;) –  MiJyn Apr 26 '13 at 8:10

In the Additional Drivers tab you see these three options:

nvidia-310: nvidia proprietary driver in the version available when your Ubuntu version was first released

nvidia-310-updates: nvidia proprietary driver in latest version available from the "updates" repository. If a new nvidia driver will be available in the next 9 month (support time for your Ubuntu 13.04) there is a good chance that it'll be installable through this option.

nouveau: open source version of the nvidia driver. This is default option because of its opensource license.

I advise you to choose "nvidia-310" for now.

Thanks, that helps. So the non-updates version is the safest option but I would prefer to be kept up to date. Is the "-updates" version just a gamble or is it generally stable as well? –  OpenTangent Apr 26 '13 at 8:31
    
For now the two options are the same and will install the same package. The nvidia-310-updates will be eventually be updated when nVidia will release a new driver version. I don't own a nVidia card, so I don't know if the -updates versions are generally stable. –  lupp0l0 Apr 26 '13 at 8:49
