I am running Ubuntu 12.04 32 bit and when I try to upgrade to 12.10 I see an error saying that my computer will run slowly.

enter image description here

If I upgrade to 12.10 and then 13.04 will my computer still run slow or will 13.04 run on my computer smoothly. I have an IBM thinkpad T42 with a 1.7 GHz processor and 1 gig of Ram.

It would be helpful if you would add to your question what hardware prompts this. –  Uri Herrera Apr 29 '13 at 16:54

The main reason for this is that "Unity 2d" is removed in 12.10, and if you don't have proper graphics support (or a really good processor) Unity3D will run slow.

This is because Unity3D will be running through LLVMpipe, which basically runs all the graphics on the main processor.

The website mentioned on the error box states:

If you choose to continue anyway, Ubuntu will try to run using software rendering (via LLVMpipe). While llvmpipe is pretty good on modern CPUs, if your video card is old your CPU is likely old too, and it may result in unusable performance.

Alternatives may include sticking with an old ubuntu release or switching to one of the lighter weight derivatives or Debian. For 12.04 and 12.10, ubuntu-classic (no effects) is also a feasible option. To do this, install the gnome-session-fallback package, and then on the login screen click the gear icon and select "Ubuntu-classic (no effects)".

How to tell if your are running the 2d or 3d: Am I using Unity or Unity 2D?

If you are running 3D currently I may mean that the new drivers don't support the card on your machine, or if there is a chance of getting graphics drivers working it probably won't be easy, and these problems will likely continue in 13.04.

So probably the best options:

  • Stick with 12.04 (still use the version of unity you are using)
  • Or, Move to Xubuntu, Kubuntu, Lubuntu and upgrade (other desktops, will not look like unity)
