I'm using 12.10 with Unity 3D on my laptop and it's really laggy compared to when I used 12.04 with Unity 2D

How can I install Unity 2D for 12.10?

  • They removed unity 2d. I don't know if you can get it back. Try a different desktop environment like XFCE.

  • Why can't you just purge unity3d from ubuntu 12.10 and install unity2d from http://packages.ubuntu.com/quantal/unity-2d via gdebi-gtk or dpkg. Another option would be to compile it from source.

Unity 2D has been removed ; in it's place, LLVMpipe is now used to perform the relevant shader operations on the CPU, in effect, taking the place of dedicated graphics hardware.

See ; http://www.phoronix.com/scan.php?page=news_item&px=MTE2MTQ

This may work better on a 64-bit install, if you have the hardware, as noted in the article.

There is a work around for those troubled by lags in Unity. For this, you need to add the following line in your ~/.xprofile file. If the file doesn't exist, create it.

export UNITY_LOW_GFX_MODE=1

The line enables low graphics mode in Unity which disables some fancy effects like active blur and transparency.

  • I'm not sure why you'd recommend installing LowLevelVirtualMachine in this case?
