I think the 2nd issue is a bug in the graphics component. We have seen it
across distributions and hardware. Every system that I've upgraded the kernel
on to something recent has had the problem disapear.
Try upgrading the kernel with the following directions:

If you need a better tutorial we can put one together. I know Jason is
integrating his kernel with Trisquel now so you might be able to apt-get it
from the Trisquel repository too. I haven't inquired or looked yet though.
