How to Change From SNA to UXA Acceleration Methods

perhaps if you show us at least what Intel chipset and video subsystem
you are using we can try to see if there is someone with the same
problem and collect more data. Without additional bits I don't know if
we can do something for you.
For example with my old P3 with an i830 I can't boot at all without
UXA. And I need to put it on xorg.conf because 20-intel.conf doesn't
make any difference on my notebook, but Lubuntu works well on a HP
Mini 1034nr netbook with an Atom 270 and 945GSE chipset without this
