Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have an emachines pc with yes I know crappy onboard nvidia geforce 6150se graphics and both unity and gnome shell run very bad with lagging. The open source nouveau driver just crashes with a "dri failed to idle" error.

Any tips on getting this to work? I tried all the drivers from the additional drivers tab

It doesn't matter which version of ubuntu 12.04 or 13.04 just as long as it works.

thanks in advance.

There is no majic here, Ubuntu 13.04 is out because the hardware is too old. Try Xubuntu or Lubuntu instead. With 12.04, Unity-2d should work, but if not, again, Xubutnu 12.04 would be a good choice. –  mikewhatever Sep 10 '13 at 20:16
Would a video card upgrade help? –  user158170 Sep 10 '13 at 21:32
Yes, it should, but I doubt it's going to be a worthwhile investment. –  mikewhatever Sep 11 '13 at 14:30
